General
Machines of product range BW 100/120 AD/AC-4 are tandem vibratory rollers orcombination rollers for compaction work in road construction. They are most suitablefor the compaction of bituminous materials as well as light compaction tasks inearthwork. Compaction is achieved by the vibration of both drums or the vibration ofthe drum and the static load of the rubber tires. The power output from the watercooled Kubota diesel engine is transferred to drums or wheels (travel and vibrationsystems) and to the steering via the hydrostatic drive systems of the machine. Thistype of power transmission ensures lowest possible efficiency losses.
Both drums of the BW 100/120 AD-4 are fitted with both travel motors as well asvibration motors. The motors for the respective drive systems are always arrangedon one side of the machine. Since it is beneficial for many applications (e.g. whenlaying asphalt layers) to work with one vibrating and one static drum, the machine isequipped with a vibration shut-off valve for the rear drum.
On machines of type BW 100/120 AC-4 the wheel set is driven by two travel motors.This roller combines the high compaction power of a vibration drum with the excellentsurface sealing effect of rubber tires in one machine. This machine obviouslyachieves considerable savings in costs when compared with a pure vibratory orpneumatic tired roller.
The standard equipment of the machine includes a gravity sprinkler system. Apressure sprinkler system is optionally available on request. In connection with thescrapers the water sprinkler system avoids picking up of material by the drums.
On the AC-machines a pressure sprinkler system prevents sticking of dirt andbitumen to the rubber tires. For this purpose the tires are sprayed with emulsion.
Front and rear frames of the machine are joined by an oscillating articulated joint.The amply dimensioned oscillation angle makes sure that the drums always haveground contact over the entire width.
Both travel motors are fitted with integrated brakes working as parking brakes.Depending on the position of the brake solenoid valve these brakes are released bycharge pressure when starting the engine and applied when shutting the enginedown.

Maintenance
The tandem/combination rollers of series BW 100/120 AD/AC-4 are highperformance machines for the extremely difficult use in asphalt compaction and earthwork. To be able to meet these demands the machine must always be ready to beloaded up to its limits. Apart from that, all safety installations must always be fullyfunctional when working under the partly very dangerous conditions on a constructionsite.
Thorough maintenance of the machine is therefore mandatory. This not onlyguarantees a remarkably higher functional safety, but also prolongs the lifetime of themachine and of important components.
The time required for thorough maintenance is only minor when being compared withthe malfunctions and faults that may occur if these instructions are not observed.
The maintenance intervals are given in operating hours. It is quite obvious that witheach maintenance interval all the work for shorter preceding intervals must also beperformed. During the 2000 hour interval you must also perform the maintenancework for the 500 and 1000 hour intervals.
It should also be clear, that with the 2500 hours interval only the work for the 10 and500 hour intervals must be performed.
For maintenance work you must only use the fuels and lubricants mentioned in thetable of fuels and lubricants (oils, fuels, grease etc.).

Checking the valve clearance
IMPORTANT:
The valve clearance must only be checked and adjusted when the engine iscold.
The cylinders are counted from the flywheel end, i.e. cylinder 1 is on theflywheel side.
1. Remove the cylinder head cover.2. Align the mark „1TC“ on the flywheel and the notched part (1) on the plate so
that piston no. 1 is in compression stroke or overlaps top dead centre (TDC).3. Measure the valve clearance marked "1" with a feeler gauge.4. Correct the clearance by the setscrew if it is not within the limits of the specified
factory data.
Valve clearance (cold) Factory settings 0,20 mm
(The values apply for intake and exhaust valves)
Service Training
________________________________________________________________________________________BW 100/120 AD Series 4 C 7BW 100/120 AC Series 4
Please note that the TC-mark is only valid for cylinder 1. There is no mark for theother cylinder.Cylinder 1 is in compression stroke when the TC-mark is visible in the window (2)Now turn the flywheel further, until the other valves overlap top dead centre andadjust the valve clearance accordingly.
Note:
• The "TC"-mark on the flywheel applies only for cylinder no. 1. The other cylinderhas no "TC"-mark.
• When the „TC“-mark is aligned with the punched mark on the rear disc, piston no.1 is in top dead centre position. Now turn the flywheel bz 15° clockwise or anti-clockwise to check whether the pistons are in TDC-position (compressionposition).(The piston is in TDC when intake and exhaust valves do not move. When bothvalves are moving, the piston is in overlapping position.)
• Finally turn the flywheel by 360 ° to ensure that „TC“-mark and punched markmatch exactly. All valve clearances must be set to the nominal value.
• Turn the flywheel two to three times in anti-clockwise direction to check the valveclearance.
• After adjusting the valve clearance retighten the locking nut of the setscrew.

Engine solenoid:
The machine is equipped with a solenoid which works according to the principle„ENERGIZED TO RUN“. This solenoid has the benefit that the engine will beimmediately shut down in case of a fault in the electric system. A disadvantage is thequite costly design of the solenoid with two coils.
Nominal currents of windings:
Pickup winding (PW) 51 A
Holding winding (HW) 0.7 A
Fig. 14:
Function of the engine solenoid:
The pickup winding (PW) is directly triggered via potential 30. Once the engine hasstarted and oil pressure is available the voltage to the pickup winding is interruptedand voltage is only applied to the holding winding.

Travel system:
On the machines described in this training manual the travel system consists of a closedhydraulic circuit. It mainly consists of the travel pump with the integrated safety elements, twotravel motors, the hydraulic oil filter and the hydraulic oil cooler.
The installation of a hydraulic pump with variable displacement into a closed hydraulic circuitis a perfect solution for a hydrostatic travel system, because with this design the traveldirection can be reversed without any problems.
The travel pump is flanged to the flywheel side of the diesel engine. It is directly driven by theengine with constant speed.
The tandem gear pump driven by the auxiliary output of the diesel engine consists of asteering/charge pump and a vibration pump. The return flow from the steering valve is fedthrough the charge oil port into the travel pump.

Besides its function of supplying the closed circuit with cool and filtered oil as replacement forleakage and flushing losses, the oil from the charge circuit is also used to release the travelmotor integrated brakes:
All safety and control elements needed for the operation in a closed hydraulic circuit areintegrated in the travel pump. These are:
High pressure relief valves (380 bar) with integrated boost check valves
Charge pressure relief valve (24 bar)
Servo control
The travel motors (on AD-machines) are hydraulically connected parallel to each other. OnAC-machines all three motors are arranged parallel to each other.

Pilot pressure is used to operate the pump out of neutral position to the desired pumpingdirection (direction of oil flow).
A manually operated 4/3-way valve directs the pilot oil flow (from the charge circuit) to thecorresponding control piston side in the servo control. The 4/3-way valve is controlled by thetravel lever and the travel cable.
In neutral position both control chambers are loaded with case pressure. When opening the4/3-way valve pilot oil (from the charge circuit) is directed to one of the control piston sidesand moves the control piston to the corresponding direction.
The swashing lever between the control piston and the swash plate transfers the controlpiston movement to the swash plate. The needle bearing mounted swash plate swivels to thechosen direction. This causes the axial movement of the pistons inside the cylinder block.The axial movement draws oil into the pump and presses it to the travel motors.
All working pistons are drilled through their entire length. Pressure fluid flows through thesebores into the areas between the slipper pads and the surface of the swash plate. This formsa hydraulically balanced field, on which the slipper pads can slide without any metal to metalcontact between swash plate and slipper pads. The feedback lever on the control pistondetects when the swash plate has reached a position that corresponds with the displacementof the travel lever. This feedback lever controls a pilot oil portioning valve which interrupts thepilot oil flow to the control chambers when the swashing angle corresponds with the positionof the travel lever. Swashing angle and displacement of the working pistons (oil flow rate)remain constant, until a new control command requires a different swashing angle.
When changing the swashing angle through the neutral position to the opposite side, the flowdirection of the oil and the sense of rotation of the travel motors will change. The sphericalvalve plate centres cylinder block, which is mounted on the splines of the drive shaft. Thisavoids the appearance of undesired transverse forces.
The complete drive consisting of
valve plate
cylinder block with working pistons and
swash plate
is held together and preloaded by Belleville springs. This immediately eliminates anyappearing wear, increases the efficiency of the pump and prolongs the lifetime considerably.
When controlling the travel pump pressure will build up in the line between pump outlet andmotor inlet. This pressure depends on the load acting on the travel motors. This pressurekeeps the boost check valve inside the high pressure relief valve for this particular side of theclosed hydraulic circuit closed. Cool and filtered oil can now only enter into the closed circuiton the opposite side (low pressure side). The high pressure relief valve limits possiblyoccurring extreme pressure peaks to the adjusted value. If one of these valves responds,hydraulic oil will flow out of the high pressure side and enter the low pressure side throughthe corresponding boost check valve.

Control
The servo control of the pump is an integral part of the pump housing and consists mainly of:
the manually controlled 4/3-way valve (1)
the control piston (2)
the feedback lever (3)
the swashing lever with the swashing cradle (see Fig. 3).
Service Training
________________________________________________________________________________________BW 100/120 AD Series 4 D 7BW 100/120 AC Series 4
Travel pump control
When actuating the travel lever the 4/3-way valve moves out of neutral position to thedesired direction and guides the pilot oil flow through the pilot oil portioning valve to thecorresponding control piston side. The control piston moves to the corresponding directionand operates the swash plate via the swashing lever accordingly.
The feedback lever, which is mounted with its ball head in the pump control shaft, follows thecontrol piston and interrupts the pilot oil flow when the control piston has reached a positioncorresponding with the displacement of the travel lever. The pump can now deliver oil to thetravel motors.
The oil from the opposite control chamber flows through the 4/3-way valve as leak oil into thepump housing.
The supply bores to both control chamber sides are fitted with nozzles (swashing timenozzles). These nozzles restrict the pilot oil flow and enable a very sensitive control of thepump.
Control in neutral position

The feedback lever controls the pilot oil portioning valve so that the swashing angle remainsunchanged, until the introduction of a new control command.
Control actuated
When the 4/3-way valve is in neutral position, the pressure values in both control chambersare identical (case pressure = max. 3 bar).

Charge pressure relief valve
The charge pressure relief valve belongs to the group of safety elements in a closedhydraulic circuit. This valve limits the pressure in the charge circuit to the adjusted value.
Charge pressure relief valve
The charge circuit is needed for the compensation of leak oil and flushing quantities in theclosed hydraulic circuit. Charge oil is also required to control the pumps and to release theparking brake.
Since feeding of cool and filtered oil is only possible on the low pressure side of the closedcircuit, the pressure in the low pressure side is identical with charge pressure. If the travelpump is in neutral position, both boost check valves can open and let in oil from the chargecircuit. In this case the pressure in both sides of the closed circuit is identical with chargepressure.

Drum drive motor:
Poclain travel motor type MK04
Both drums are driven by Poclain travel motors type MK04. These are radial piston motors.These drive motors consist of the outer housing, the flat distributor, the cylinder block withthe working pistons, the output shaft and the brake. The brake is designed as a Hirth-toothing.
The housing consists of
Ø bearing section (bearings for output shaft)Ø torque module (cam race)Ø oil distributor andØ Hirth brake
The function of the radial piston motor is described hereunder. The piston positionsmentioned in the description are shown in the corresponding illustration.
The movement of a piston along the cam race must be examined during various phases ofthe rotation.

________________________________________________________________________________________BW 100/120 AD Series 4 D 13BW 100/120 AC Series 4
Piston position 1:
Ø The oil enters into the oil distributor under pressure, flows through the distributor andpresses against the piston. This is the start of a rotation. Due to the pressure on theback of the piston the roller will move along the cam, thereby causing a rotarymovement of the cylinder block.
Piston position 2:
Ø At this point the oil flow to the piston has reached its largest cross section. The pistoncontinues its travel along the cam race towards the valley between two cams. Theopening cross section decreases with continuing rotary movement.
Piston position 3:
Ø Once the piston has reached the deepest point the oil flow to the piston is cut off. Thepiston is no longer driven. It has reached its dead centre. Another piston must now bedriven to move the previous piston out of dead centre position.
Piston position 4:
Ø By driving other pistons the previous piston is moved out of dead centre position. Theoil behind the piston is connected with the low pressure side and the retracting pistonpresses it back to the pump.
Piston position 5:
Ø The oil supply back to the pump comes close to an end, the connecting bore betweencylinder and low pressure side closes slowly. The piston will now reach its seconddead centre position. This point is the start of a new working cycle.
Reversing the oil flow reverses also the rotation of the motor.

Brake actuation MK04 motor (drum drive motor)
The travel system is equipped with a Hirth-type brake in the travel motors. This brake servesas parking brake to park the machine. (to secure the machine when the engine is running orto park the machine with the engine shut down) and as emergency brake.The brake control is accomplished via a 3/2 way valve which is located at the front in theengine compartment. If the solenoid valve is supplied with electric current when the engine isstarted, the valve will switch over and guide charge pressure into the brake housings. Thisreleases the brakes.If the solenoid valve is de-energized while the engine is running (e.g. when actuating theemergency stop switch), the oil pressure in the brake housings is relieved to the tank and thebrakes will close.

During travel operation the machine is braked by the closed hydraulic circuit. When movingthe travel lever to neutral position the supply from the pump is interrupted. The machine willstop.
However, both travel motors are additionally fitted with brakes. These brakes work only asparking brakes. The brakes are automatically relieved by the charge pressure building upwhen starting the engine. Should the charge pressure drop considerably (failure or shut-down of the engine, damage in the hydraulic system), the brakes close automatically.
When shifting the travel lever to neutral position the brake closes after a short while.The brake closes also when the seat contact switch is open.
The brakes can be relieved mechanically with screws.
The mechanical releasing of the brakes works as follows:
- Unscrew the 2 plugs (191)- Press the screws (192) against the springs (193)- Tighten both screws (192) alternately and in steps until they bottom (approx. 2
revolutions) (max. 35 Nm)
To close the brake, proceed in reverse order.

The rubber tires of the BW 100/120 AC-4 are driven by two radial piston motors PoclainMSE 02 which are joined parallel to each other and also parallel to the drum drive motor.
The function of the motor is identical with the previously described Poclain motor MK04.However, the main difference is the design of the integrated brake. The MSE02 is fitted witha multi-disc brake. This consists of inner and outer discs which run permanently in an oilbath. Since the brake is normally only applied in events of emergency, it is almost wear free.If needed, the brakes can be released with the help of a brake releasing device. For thispurpose a ball valve is installed in the engine compartment. By operating this valve oil can bedirectly guided to the motors (drum as well as wheel drive motors). For this purpose thesteering wheel must be slowly turned for approx. two turns in clockwise direction. In this casethe steering wheel or Orbitrol has the effect of a pump and delivers oil to the brakes (to thedrum as well as the wheel drive motors). The brakes are thereby is released.

The vibration pump is directly driven by the timing gear side of the diesel engine.Vibration pump and steering/charge pump are joined together to a tandem pump unit.The gear pump delivers the hydraulic oil out of the hydraulic oil tank to the vibration controlvalve.
If the vibration is switched off the hydraulic oil flows directly back to the tank.
When the vibration is switched on, the control valve directs the oil flow to the in lineconnected vibration motors (BW 100/120 AD-4), or to the vibration motor on the drum (BW100/120 AC-4).
The vibration motors (gear motors) drive the vibrator shafts in the drums with constant speedvia Bowex couplings.The rotation of the exciter shafts with the attached eccentric masses generates the vibrationof the drums, which are suspended in rubber elements. From the second vibration motor theoil flows back through the control valve block to the tank (open circuit).
The standard equipment of the AD-machine includes a shut-off valve for the rear drumvibration. When operating a ball valve the oil flow is directly returned to the tank after the firstmotor (front drum) via the control valve block

Vibration pump
The vibration pump is a directly driven gear pump.
Fig 21:
The drive gear is connected with the auxiliary drive of the diesel engine via a pinion. Drivegear and driven gear are positioned by a bearing plate in such a way, that the gears meshwith minimum clearance when rotating.
The displacement chambers are created between the tooth flanks, the inside wall of thehousing and the faces of the bearing plates.
During operation of the pump the hydraulic oil is transported in these chambers from thesuction side to the pressure side. This causes a vacuum in the suction line by which thehydraulic oil is drawn out of the tank. These tooth chambers convey the fluid to the pumpoutlet from where it is pressed to the consumer. To ensure a safe function of the pump thetooth chambers must be so tightly sealed that the hydraulic fluid can be transported from thesuction side to the pressure side without any losses.
Outer gear pumps are fitted with gap seals. In dependence on the operating pressure therewill be losses from the pressure side to the suction side. An axial pressure field presses thebearing plate on the cover side against the front face of the gears, making sure that only avery little quantity of oil will leak from the pressure side to the suction side when the pressureincreases.
The pressure field is always under the actual system pressure.
The vibration pump delivers the hydraulic oil from the tank to the vibration motors and fromthere back to the tank.

Vibration control valve
With the vibration control valve the vibration is electrically switched on and off.
The valve consists of the solenoid operated valve piston, the pressure relief valve for thevibration circuit and the brake valve to brake the exciter shafts when switching the vibrationoff.
When switching the vibration on the direct return flow to the hydraulic oil tank is interruptedand the hydraulic oil is guided to the vibration motors.
The high pressure (starting pressure) in the vibration circuit generated by the resistance ofthe resting exciter shafts is limited to 210 bar by a pressure relief valve inside the controlvalve block.
When operating the control valve the valve spool opens also a direct connection between theoutlet of the second vibration motor and the oil tank.
When switching the vibration off this direct connection is interrupted. The hydraulic oil, whichis now displaced to the control valve by the still rotating vibration motors is applied to 110 barpressure relief valve (brake valve). This valve brakes the rotation of the exciter shafts withinthe shortest possible time.

Vibration motor
On the machines of series BW 100/120 AD-4 and BW 100/120 AC-4 the exciter shafts insidethe drums are directly driven by vibration motors.
These vibration motors are gear motors which are directly connected with the exciter shaftsvia Bowex couplings.
The design of these vibration motors is almost identical with the design of the vibration pump.A more detailed description of the design is therefore not required.
On the BW 100/120 AD-4 the vibration motors are connected in series.
The standard equipment of the machine includes a shut-off valve for the rear drum vibration.When operating a ball valve the oil flow is directly returned via the control valve block to thetank after the first motor.

The steering pump delivers the hydraulic oil from the tank to the steering valve and theconnected steering cylinder. When the steering is not operated the complete oil flow isguided through the fine filter to the charge ports on the travel pump and further via the coolerto the tank.When turning the steering wheel the distributor valve guides the oil flow to the piston orpiston rod side of the steering cylinder.
A measuring pump in the steering unit measures the exact oil quantity corresponding to theturning angle of the steering wheel and delivers this oil to the steering cylinder. The steeringcylinder extends or retracts and articulates the machine. The steering unit is fitted with anintegrated pressure relief valve. This valve limits the steering pressure to 140 bar. Since thehydraulic oil flowing out of the steering system is used as charge oil for the closed travelcircuit, the charge pressure value must be added. When testing the pressure a value of 160bar would therefore be measured.

Steering valve
The steering valve block consists mainly of distributor valve, measuring pump, steeringpressure relief valve and the shock valves. When turning the steering wheel the oil flow fromthe pump is directed through the distributor valve to the measuring pump. The measuringpump, in turn, directs the oil flow through the distributor valve to the corresponding side ofthe steering cylinder. The machine is fitted with a so-called “Open Centre” steering valve, i.e.in neutral position of the valve the incoming oil flows through the tank return bore directly tothe charge ports for the closed travel circuit.

The rating pump determines the exact oil quantity in dependence on the turning angle of thesteering wheel. The oil quantity directed to the steering cylinder articulates and steers themachine. The high pressure relief valve in the steering unit limits the pressure in the steeringsystem to 140 bar. Since the oil leaving the steering system is used to charge the closedtravel circuit, this charge pressure value must obviously be added when checking thesteering pressure. The steering unit is fitted with so-called shock valves in each pressureside to the steering cylinder. These valves are adjusted to an opening pressure of 200 bar.The valves compensate extreme pressure peaks which may occur, e.g. when driving overobstructions, and protect the system against overloads.Each of these shock valves has its additional anti-cavitation valve. This anti-cavitation valvesprevent the appearance of cavitation, which may be caused by the response of the shockvalves. A check valve near the inlet port of the steering unit makes sure that no hydraulic oilwill flow back to the steering pump if the machine is articulated by sudden external forces. Insuch a case the steering cylinders would act as pumps and press the oil back to the pump.

Relay cross reference in developed presentation
Switching symbols of parts of electric components (relays, switches ...) are drawn separatelyand arranged in such a way, that every current path can be easily tracked. The spatialrelationship of individual contacts is of no importance. A straight and clear presentationwithout any crossing of the individual current paths is of highest importance. Relay crossreferences can therefore be used to trace signals which have to be followed on componentswith dependent contacts.Apart from this there is a contact plan under each relay coil providing information about thecontact types of a relay and where these appear in the wiring diagram.
Example 2 (Fig. 4): On sheet no. 8 the coil of relay (K99) is located in current path ”6".The contact sketch under the relay informs that a throw-over contact with thecontact types 30, 87 and 87a is triggered. On sheet no. 8 this double-throw contact is locatedin current path ”3".

Start the engine:
To start the diesel engine the following conditions must be fulfilled:
- Emergency stop switch not operated- Travel lever in neutral position (switch B08) B08 triggers relay K05- Voltage on ignition switch output 50a
Driving the machine:
- The machine can only be driven when the seat contact switch (S06) is closed and K22has switched. (OPTION !!!) Attention! Standard on machines with CE conformity !
Switching the vibration on (standard version)
Push button S13 switches ground potential to the module A03 Pin 13. A03 then switches thesolenoid valve Y71 accordingly. When moving the travel lever fully to forward or reversevibration is switched off in dependence on the position of angle sensor B 39 when a speed of6 km/h is exceeded. If the speed is fallen short of (< 6 km/h) the vibration switches on again.
Switching the pressure sprinkler system on:
Interval switch A01 switches + potential to module A03 on PIN 1. The module switched relayK79 (terminal 86) via Pin 4. This requires that the travel lever is moved out of 0-position.The module now switches relay K79 in dependence on the set interval. The contact of relayK79 then activates the water pump.
To check the water sprinkler system without deflecting the travel lever is possible when theinterval switch is to the highest stage.

Description of function
Switching offIf operating voltage is applied to the module (PIN1/2 UB, PIN10/11 ground), LED1 will light asa control light. LED 2 flashes as Stay-Alive-Indicator („Live Sign of Module“), but with aflashing frequency which depends on the current on input PIN 8 (analogue input 1).
Angle sensor:
The machine is equipped with an angle sensor under the driver’s seat, mounted to the switchguide plate of the travel lever. The angle sensor reports the travel lever position back to themodule. The sensor works with an output current of 4-20 mA.
When replacing the sensor, a zero adjustment will be automatically performed as followed.

________________________________________________________________________________________BW 100/120 AD Series 4 G 11BW 100/120 AC Series 4
Neutral position of angle sensor
The zero point of the angle sensor is automatically adjusted via the module. Once the travellever is in neutral position the brake initiator (on the travel lever) (Pin 12) is actuated. Thezero position is thereby recognized. Should the brake initiator be defective or a cable isbroken the last value is set as default for the zero point.If LED2 (on the module) flashes in intervals of one second and LED3 lights permanently, thezero point is reached.

Defect on angle sensor
The current of the functional angle sensor is in the range from 4mA to 20mA. A current flowof <2mA or >22mA on Pin 8 of the module indicates a sensor fault (sensor defective, shortcircuit, or sensor not connected, etc.). LED2 and LED3 are then used as indicators. LED2flashes fast (with 80 Hz), LED3 shows permanent light.
Constant voltage monitoring
The flashing frequency of LED 2 indicates whether the output voltage of 8.5 V on Pin 9 isoutside the permissible tolerance. If this voltage is not high enough, the angle sensor will notwork correctly and the output signal of the sensor is undefined.For this reason the flashing frequency of LED2 is set to 80 Hz, if the voltage is too low. Thisalways takes place in case of a low voltage level on Pin 9. This may be caused by a too lowsupply voltage for the module (with UB < 9,5V the voltage of 8,5V can no longer bemaintained on PIN 9) or by a defect of the module.The complete module works from a minimum voltage of UB = 6,5V. However, the analogueinputs only work from a supply voltage of 9,5 Volt, since the sensor supply voltage of 8,5Vcan only be generated if this input voltage is available.
The following functions are influenced by the angle sensor:
- Automatic vibration ON/OFF- Sprinkler system water off after 30 sec. If travel lever is in 0-position- Backup protection- Checking of neutral position

Vibration control
Manual vibrationIf no voltage is applied to PIN 14 (manual vibration on), vibration can be switched on viabutton input (vibration on) on PIN 13. Vibration is always switched on or off when a clearground potential is detected on Pin 13. If vibration is switched on, the LED on Pin 5 lights up.If the vibration button is actuated again, vibration is switched off.In case of a bridge (Active-HIGH-Signal) on PIN 16 vibration switched off at a speed higherthan 6 km/h and on again at a speed below 6 km/h.Without a bridge on PIN 16 the vibration is not switched off above 6 km/h.

Automatic vibration control (optional)
If a positive voltage is applied to PIN 14 (automatic vibration on) the LED on PIN 14 lights upand the vibration (PIN 5) is switched on and off in dependence on the travel lever position.With a bridge (Active-HIGH-Signal) on PIN 16 the vibration (output, PIN 5) is switched offwith the travel lever in a position <1 km/h and >6 km/h.Without the bridge (LOW-Signal) on PIN 16 the vibration (output, PIN 5) is only switched offat a speed < 1 km/h.

Water sprinkling controlThe sprinkler intervals are controlled by connection of a 12-stage switch to PIN 7. This switchswitches resistors in 500 Ω-steps from 500 Ω to 6 kΩ.
Sprinkling stages for pressurized sprinkler system
The total cycle (time for activation and deactivation phase) takes 15 seconds.The sprinkling intervals are set according to the following table:
Stage Activation time Deactivation time Cycle time1 0,0 s 15,0 s 15s2 1,0 s 14,0 s 15s3 2,0 s 13,0 s 15s4 3,0 s 12,0 s 15s5 4,0 s 11,0 s 15s6 5,0 s 10,0 s 15s7 6,0 s 9,0 s 15s8 7,0 s 8,0 s 15s9 8,0 s 7,0 s 15s10 10,0 s 5,0 s 15s11 12,5 s 2,5 s 15s12 15,0 s 0,0 s 15s

After stopping the machine (travel lever in neutral, evaluation of analogue signal on PIN 8)sprinkling continues with the set interval for another 30 seconds (pressure sprinkling). Afterthis time sprinkling will only be resumed after moving the travel lever out of neutral. If theswitch is in stage 12 (permanent sprinkling), sprinkling will continue after the 30 seconds,without any temporal limitation! Should be used for inspection with the machine stopped tocheck nozzles, pump etc.
Gravity feed sprinkler system
If no 12-stage switch is connected, but the gravity sprinkler switch (S05 on output PIN 4)instead, the output will permanently switch a High signal. The sprinkling system is triggeredvia this switch.With the machine stopped (travel lever in neutral position, evaluation of analogue signal onPIN 8) the HIGH-signal will still be emitted at PIN4 for another 30 seconds, after this it will beset to LOW-signal, until the travel lever is moved out of neutral again.
Fig. 2: Gravity feed sprinkler system
With both sprinkling systems the sprinkling cycle time is independent from the displacementof the travel lever, i.e. from the travel speed of the machine. Only the neutral position is ofsignificance for the automatic shut down of the sprinkling system after 30 seconds.

Description of function
Switch ignition on and start the engine• Stay-Alive-(Live Signs) LED flashes in one second intervals.• Engine running
Shut down the engine immediately• If the driver seat is not occupied (PIN 2 has HIGH–Signal) and the travel lever is actuated
(PIN 3 has Active–HIGH–Signal), the module will simulate a oil pressure fault. Relay (PIN30 + 87) switches immediately for half a second and LED6 lights for half a second.
• The holding winding of the engine solenoid is not energized for half a second and theengine is shut down.
Engine shut down with time delay• The driver's seat is occupied (PIN 2 has Active–LOW–Signal) and the travel lever is in
neutral position (PIN 3 has LOW–Signal).• When leaving the driver’s seat (PIN 2 has LOW–Signal) after shifting the travel lever out
of neutral (PIN 3 has Active–HIGH–Signal), the warning buzzer is activated.• After 2 seconds the relay (PIN 30 + 87) is switched on for half a second and LED6 lights
for half a second.• The holding winding of the engine solenoid is not energized for half a second and the
engine is shut down.
Restarting the engine• If the engine has shut down as described in point 3.4 it can be restarted within 2 seconds
after occupying the driver’s seat. This is only possible if the engine is still rotating and oilpressure (PIN 4 has Active–HIGH–Signal) is present.
• This is accomplished by switching on the BTS-output (PIN BTS) for 1 second. LED5lights for 1 second.
• The pickup winding of the engine solenoid is energized for half a second and the engineis restarted.
