3. Description: Governor

3.1 Standard Version • Range of pre-settable release speed 0.50 – 3.43 m/s • Triggering at downward or upward travel • Rope distance 200 or 300 mm • Rope diameter at 200 mm 6-6,5 mm; at 30 mm 6-8 mm • Property of rope groove:

- 40° V-groove with undercut - Flanks hardened upon request (for gearing at upward travel not mandatory)

• Safety switch complying with EN 81 (IP 65) - up to Vn = 1,00 m/s w/o snap-on contact - up to Vn = 1,00 m/s w snap-on contact as pre-cutoff

• Rope jump off guard

3.2 Functional Description The overspeed governors type 7/8/9 are safety components type approved in accordance with EN 81. They serve for engaging the safety gear and switching off the lift system at overspeed in upward or downward direction. The release speed (Va) has been factory set and sealed in accordance with EN 81-1. The governor works according to the pendulum principle. The safety switch on the overspeed governor is actuated at a speed of: • Vn up to 1.00 m/S simultaneously with the mechanical safety gear



Version 07.02

• Vn above 1.00 m/s max. 10% below the mechanical safety gear as a pre-

cutoff and the lift system’s safety circuit is interrupted. The engaging force required fort he safety gear or brake system respectively is achieved by means of an according tension weight. The overspeed governors may be used for triggering safety systems on the cabin, counter-weight or balance weight.

The tensile force generated in the governor rope by the release overspeed governor must equivalent to the higher of the following values: a) the double of the force required to engage the safety gear or b) 300 N

• The governor’s release speed on the counter-weight is set 10% higher than the one of the cabin.

• A slack rope switch must be installed on the tension weight.

Description of the triggering By means of a pressure spring which is guided by a bolt and acts on the pendulum, the pendulum pulley s pressed to the cam shape of the governor wheel. If the pre-set release speed Va is exceeded the pendulum pulley is taken off the cam shape by the centrifugal force. This initiates the following process:

• The stop pendulum is moved so far that its safety catch engages in the cam on the governor wheel. - At Vn up to 1.00 m/s the safety switch is triggered by the stop plate together with the mechanical gear. - At Vn above 1.00 m/s the pre-cutoff is triggered by the switch cam before the mechanical gear.

• The governor wheel is blocked. • The governor rope is clamped due to the v-formation of the rope groove. • This clamping causes the safety gear on the cabin or counter-weight to be

pressed in.

! The governor must not be commissioned until the lift system has been checked and any causes of malfunctions have been eliminated by expert personnel.

Resetting is made:

• Systems of up to Vn 1.00 m/s: by travelling the lift with the return control. • Systems above Vn 1.00 m/s: by manually or electromechanically resetting the

pre-cutoff and subsequent travelling of the lift with the return control. The governor is then in operating condition again.

6 Installation Instructions BODE Overspeed Governors may be installed in one of the following locations: 1. In the machinery room

• On the floor • On the sub-structure

Installation with screws and dowels (not included) on the floor. The customer has to provide a clean and even seating for the governor or the sub-structure. The governor must not be deformed when tightening the mounting screws. 2. In the pit head

• With console on the guiding rail • On the pit ceiling • On the pit wall

The console for the rail fastening is installed by means of clamping brackets. The type plate has been applied suited for this type of installation.

!For governors with lateral tope outlet or suspending types, the settings have to be made accordingly ex works. The type plate has been applied suited for this type of installation.

3. On the pit floor

• On the tensile weight with guiding stand The tension weight is vertically mounted to the floor with screws and dowels (not included). A clean an even seating is to be provided.

! The governor is to be protected against intruding of foreign objects between cam wheel and rope (EN 81-1). A suitable cover is available.

The rope outlet is to be aligned vertically from the governor to the rope mounting of the safety gear. The wrap angle must always be 180°. When installing the governor in the machinery room or pit head, a suitable tension pulley must be used. 7 Commissioning

Before commissioning, the following has to be checked: • Operability of the governor • Operability of the attachments • Mounting of the governor • Wiring of the safety switch • Installation and wiring of additional parts. • Unobstructed movement of the tension weight. • Wiring of the slack rope switch. • Vertical rope outlet.

!For testing purposes the governor has to be pressed in jerkily as otherwise the required frictional resistance is not achieved. At low speeds the safety switch will be reliably actuated when the release speed is reached.



Version 07.02

8 Maintenance The maintenance is to be made together with the lift system maintenance and is limited to the following: The free movement of all movable parts is to be checked. Cam wheel, rope groove, and O-ring on the pendulum pulley are to be inspected for damages and wear. The safety switch and additional parts are to be checked for their proper functioning. Should the rope groove be run in in direction of the rope seat groove, the governor does not need to be replaced as it features a blank die (EN 81-1; EN81-2). The governor is to be replaced if the blank die is less than 3 mm. 9 Repairs As the governor’s release speed has been factory preset, an on-site repair is not possible. In case repairs or re-settings are required, these must be either made at the manufacturer’s or the governor is to be replaced. In case of repairs BODE gladly provides a corresponding governor for the repair period. Replacing the governor does not require the governor rope to be loosened. The warranty becomes void if seal on the adjustment nut or the colour sealing on the safety switches are damaged. 10 Description and Wiring of the Safety Switch 10.1 Safety Switch 1563 (without arrest) Switch 1563 is standard on governors designed for a nominal speed of up to 1.00 m/s. It comes without snap-on contact and the NCC is automatically closed when turning out of the gear. It is triggered by the dent in the stop plate.

10.4 Pre-cutoff 1489 (with snap-on contact) According to EN 81 the pre-cutoff has to be installed at a nominal speed of more than 1.00 m/s. This switch comes with snap-on contact and has to be manually reset. It is factory set to max. 10% below the indicated release speed and is triggered by the switch cam on the stop pendulum. If the governor is inaccessible, e.g. when installed in the pit, switch 1563 is additionally installed. If switch 1489 has been triggered it must be bridged for resetting it. In order to ensure the safety despite the bridge, switch 1563 is active. Can not be retrofitted.

11. Installation of Attachments 11.1 Governor with remote release unit (FA) If the governor is installed in the pit, it can be equipped with a FA. For testing purposes the FA can be triggered via a key switch. Functional description: When actuating the key switch outside the pit a magnetic coil is excited and the push rod is pressed in direction of the switch cam. The so far freely swinging stop pendulum is thereby put in release position and blocks the governor’s cam wheel. Now the safety gear is released.

Version 07.02

Note on Installation The remote release unit is pre-fixed in its position by means of a heavy-duty dowel pin. For installing it the holder’s M8 screw is put in the right hole of the stop plate and tightened with a torque of 10 N/m. Then, wire the unit. The supply voltage is 230 V AC, 50 Hz. The coil connection is pre-mounted with a 0.75 qmm pigtail. Test the operability of the unit and, if need be, readjust the FA. Governors with a FA always include the safety switch 1563 without snap-on contact. In case, a pre-cutoff is required, switch 1489 or only switch 2239 is to be additionally installed. Switch 1489 has to be bridged and manually reset after actuating the remote release unit and engaging of the governor.

! When retrofitting the governor with a remote release unit modifications have to be made. A dent has to be filed on the switch cam so that the remote release unit’s cone presses down the pendulum. Laterally, the remote release unit has to be put in the right position. The operability of the unit is to be tested.

• When actuating the remote release unit the max. ED of 15% must not be exceeded.

• The remote release unit’s switch is to be clearly marked by means of a warning sign.

11.2 Governor with Anti-Creep Protection (AS) The governor can be equipped with an AS. The AS provides for several functions. Functional description: A magnetic coil including push rod is additionally mounted on the governor. During the controlled cabin movement, the magnetic coil is excited and holds the push rod in its end position. The stop pendulum can swing freely. When the cabin comes to a halt the magnetic coil goes dead and drops out after a delay period preset at the time relay. Depending on the position of the cam disc the magnetic coil’s push rod is pushed against the switch cam or slides over it. If the cabin now starts moving due to overloading or other reasons, the push rod keeps the stop pendulum in release position. The cam wheel is blocked and engages the safety gear. The safety circuit is interrupted by the switch on the AS. Depending on the respective position of the stop cam to the stop pendulum the release distance varies between 9 cm and 25 cm.

Version 07.02

Functional description when used to secure the installation: With lift systems where the drive unit is installed in the pit the AS may serve as a safety device during installation. When opening the lower lift door for maintenance works in the pit, the magnetic coil goes dead and drops out. Functional description for securing when enlarging the cabin without modifying its nominal load: If the cabin is enlarged without modifying its nominal load the AS in combination with a load weighing unit can be activated when exceeding the nominal load. Sinking and further travel of the cabin is then prevented by the safety gear. Functional description when used to prevent from overtravel: The AS may serve as a safety device if the safety space is short. For this, a contact has to set the AS voltageless when reaching the safety space so that the governor is blocked and the safety gear is engaged. Notes on Installation: The AS is supplied unattached together with the governor. For installing it the M8 screw of the AS holder is inserted in the right hole of the stop plate. Now, the 4 mm split pin is inserted in the hole in the holder and thereby fixed. Tighten the holder firmly with the nut. Wiring is to be made in accordance with the wiring diagram. Wiring diagram

! When retrofitting the governor with anti-creep protection modifications are required. A dent must be filed on the switch cam so that the coil’s cone presses the pendulum down. Laterally, the anti-creep protection unit has to be set in the correct position. The operability of the unit is to be tested. The holder of the anti-creep protection is to be tightened with a torque of max. 10Nm .

• When installing the anti-creep protection no remote release unit can be

additionally installed. However, the anti-creep protection may additionally serve as remote release unit, if it is set voltageless for this purpose.

• The switch for the remote release function is to be clearly marked with a warning sign.

• The AS should be battery buffered as the governor would otherwise be blocked in the event of a power failure.

11.3 Incremental Encoder Attachment An incremental encoder can be mounted to the governor, the tension or diverter pulley. For this purpose, the tension or diverter pulley must feature a V-groove. Retrofitting a encoder attachment is not possible. Included in delivery • Adapter plate to be mounted on the governor. • Toothed belt disc 44 teeth mounted on cam wheel. • Toothed belt on toothed belt disc. • Pinion 11 teeth (in bag). • 3 mounting screws M4 (in bag)



Version 07.02

Installation Instructions Remove the adjustable adapter plate from the pedestal. Mount the incremental encoder with the countersink screws supplied on the adapter plate. Slide the pinion on the axle of the incremental encoder and pre-mount it with the M4 set screw. Now move the pinion on the axle so that the toothed belt is correctly aligned in both turning directions of the cam wheel. Then remove the adapter plate with the incremental encoder and firmly tighten the set screws on the pinion. Secure the screws with Locktite. Now the adapter plate can be reinstalled.

! Take care to use tension weights suited for the respective governor type.

• When sliding on the pinion take care that the set screw does not extend into the borehole.

• Tighten the toothed belt only slightly. 12. Tension weights Different tension weights can be used for operating the overspeed governor. The type of tension weight depends on the mounting type. For all tension weights a slack rope switch is supplied. 12.1 Tension weight for mounting on the guiding rail; stopping in downwards direction Order number: 580 031 (Ø300) / 580 034 (Ø200) For this tension weight a shifting bracket for mounting on the guiding rail is required. The tension pulley is to be mounted in a way allowing for sufficient play below the tension pulley so that the slack rope switch can be safely switched and shut down the lift system in case the governor rope is stretched or tears. The tension pulley is to be protected against down falling objects. 12.2 Tension weight for mounting on the guiding rail; stopping in upwards direction (Order number: 580 160 (Ø300) / 580 161 (Ø200) For this tension weight a shifting bracket for mounting on the guiding rail is required. The shifting bracket features a preventer mechanism for stopping at upwards travel. The sleeve of the preventer arm has to be loosely shifted over the grooved bolt. The arm loosely rests on the tension pulley holder. All parts must be free-moving. The tension pulley is to be mounted in a way allowing for sufficient play below the tension pulley so that the slack rope switch can be safely switched and shut down the lift system in case the governor rope is stretched or tears. The tension pulley is to be protected against down falling objects. 12.3 Tension weight with governor or diverter pulley mounted on the pit floor There are two types of guiding stands to be distinguished: tension weights with a single type guiding stand with integrated diverter pulley and a duplex type guiding stand. Both are suited to be employed with a duplex safety gear. If the governor is mounted directly on the tension weight, a heavier weight is to be used. The guiding stands are to be



Version 07.02


mounted vertically and protected against dirt. Please check, whether the slack rope switch switches.

!All tension weights: Depending on the make of the governor rope or sluggishness of the safety gear the tension weight may have to be increased.

12.4 Cover for tension pulleys (Drawing 2 580 029) The cover for the tension pulley is to be mounted as follows: Mount the arm with the clamping brackets on the guiding rail. Place the perforated rubber mat on the arm so that both sides are equally long. Then fix the mat with the three securing plates.
