Safety
1- Do not connect main electrical plug until all hydraulic connections have been made. Pump will start
when power is applied.
2- Be aware that the heat exchanger at the top of the unit, the solenoids on the valves and the motor
will reach temperatures that may exceed 120 degrees Fahrenheit.
3 -Inspect all hydraulic hoses in your entire system at least once per month. Look for cracks in the hose
coverings and leaks in tubing joints.
CAUTION: Be aware that even though the unit may not be running, under some operating conditions
it may start unexpectedly.
CAUTION: Be aware that though the unit may not be running, the system may be pressurized up to
2600 psi and that the parts of the machine may reach temperatures exceeding 120 °F.
Startup Procedure
1 – Through the filler port, fill the unit with 5 gallons of hydraulic oil for HS-10-1300 or 7 gallons for HS-
20-2600, any standard mineral oil grade VG 24 or 32 can be used. It is normal to require added oil
once the system has been run and the lines are filled. The pump will stop and a notice on the Status
HMI screen will indicate a low oil condition. Add more clean oil and the pump will restart when the
proper oil level is reached.

Start Up (Continued)
2 – Connect hoses to the A, and B ports. On HS10-1300 and the HS15-2000 units, the port size is SAE8
and on the larger HS20-2600 units, the port size is
SAE12. (Note: In the case of a core pull unit, the rod
end cylinder connection will go the A port and the cap
end cylinder connection will go to the B port)
3 – Plug the electrical power and interface plugs directly
into their respective receptacles. The standard
machine voltage is 208v, three phase. Be sure the
voltage to the unit is the same as the sticker on the
door of the unit as the machine is available in several voltages for different installations.
4 – Turn on the power to the HPU. The unit is ready to operate as soon as the Status screen appears on
the operator station.
5 – Enter Pressure and Flow if the default settings are not desired (via “SETUP” page on HMI – See Touch
Screen Pendant Operation section below)
Touch Screen Pendant Operation
The operator station has five primary pages which the operator
needs to control the machine. The Status page (appears at
start up), Set Up page, Multiset page, Recipe page and the
Maintenance page. Each page has displayed information,
like pressure values and timer settings and control buttons
for turning thing off and on.
Each is explained as follows;

Machine Maintenance and Troubleshooting
Many features have been incorporated on the HydraSmart HPU to make maintenance as fast and easy
as possible. Here are a few of them:
1. Easy to access oil filter with a reminder based on actual running time that appears on the HMI to tell
you when to change it.
2. Lighted solenoid caps to indicate visually when they are energized. Valves include manual override.
3. Faults are annunciated on the Status screen as well as the Maintenance screen.
4. Manual control of the solenoids is provided on the maintenance screen for “test firing” all valves.
5. A continuous cycling of valves SV1 and SV2 with variable timing is available on the OEM page. CAUTION: Be aware that even though the unit may not be running, under some operating conditions
it may start unexpectedly.
CAUTION: Be aware that though the unit may not be running, the system may be pressurized up to
2600 psi and that the parts of the machine may reach temperatures exceeding 120 °F.
Filter replacement: The recommended time interval for replacing the filter element is 3000 hours.
Follow the below steps to replace the filter element:
1 – Turn the Hydraulic Power Unit OFF via the core pull button on the main molding machine HMI or by
pulling the power plug of the HPU.
3 – Place a drain pan under the filter and remove the filter element by turning the filter canister counter
clockwise.
4 – Refer to the parts list for your machine to ensure that you use the recommended filter unit. It is a 5
micron hydraulic system filter. Lubricate the seal on the replacement element and install the new
filter by turning the filter canister clockwise. Screw in by hand until the element contacts the sealing
surface, then tighten by hand ¾ turn more. Visually inspect to insure that the seal ring is not
protruding from one side of the seal. Top off the oil reservoir, if necessary, and then put the
machine back into service and observe the filter for a few minutes to insure there are no leaks.

Machine Maintenance and Troubleshooting (Continued)
Fluid Level: Check maintenance screen for status. If the Fluid level is low, the OIL LEVEL indicator will
read “LOW.” If the level is low, fill the reservoir through the filler port until the level reaches to the
middle of the filler port. The motor will not run if the level is low and will start again when the
proper oil level is restored.
Fluid Temp: Check maintenance screen for status. If the temperature is too high, the TEMPERATURE
indicator will read “HIGH.”

Machine Maintenance and Troubleshooting (Continued)
Motor Drive Trouble Shooting Tips
Using the display
The motor on the HydraSmart units are powered by an A.C. vector drive. The drive contains a red LED
display that displays many types of useful information. The default display is the speed of the motor
in set frequency which is in Hertz. The base speed of the motor which is around 1750 RPM is
achieved at 60 Hz. The maximum motor speed is 3000 rpm or 100 Hz. The higher the desired flow is
set on the operator HMI, the faster the motor will run. Maximum flows are achieved between 70
and 95 Hz depending on which HydraSmart unit is being used.
Other useful drive information is available by using the up and down arrow keys on the drive to change
the address of the information to be displayed. Press the key marked with an “M” (mode) and the
display will change to a “Pnnn” with nnn indicating the parameter number. Use the up and the
down arrow keys to increase and decrease the parameter number. Press the M button again and
the display will show the value for that parameter.
CAUTION: Important drive parameters can be changed in this same way. Operation will be negatively
affected and in some cases damage to the motor may result. Only the parameters suggested here
are to be used to view conditions in the drive. Do not make any changes to the values you see in
any parameter. If you accidently enter undesired information, DO NOTHING, and the parameter will
change back to the original value in about 15 seconds.
Resetting Faults.
When faults occur, the drive will protect itself when possible by taking itself out of service or “tripping.”
Try to clear the cause of the fault before proceeding. There are several different ways to return the
drive to operation depending on the fault. First try pressing the red button on the drive control
panel. If this doesn’t restore operation, go to the MAINTENANCE screen on the HMI and press HPU
OFF, then press the red button on the drive. If this fails, remove power from the machine and wait
15 seconds or until the fan on the drive stops then re-apply power.
HydraSmart Power Unit Page 18
Motor Drive Trouble Shooting Tips (Continued)
Useful Motor Drive Parameters
There are many drive parameters, below are the most likely to be useful in troubleshooting the unit.
P508 Motor Current. When the pump is idling, this value will be less than half of the current on the
nameplate of the motor. When a valve first opens, motor current will ramp up to several times the
rated current. This is normal.
Use: watch this parameter for higher than normal idle current which may indicate valve leakage or
incorrect adjustment of pressure relief valve.
P521 Analog input value. This will indicate the motor speed being requested by the setting of oil flow
on the HMI. An indication of around 4 (milliamps) indicates minimum motor speed and flow.
Indications of around 17 ma (depending on the size of the HydraSmart unit) indicates maximum
motor speed and oil flow.
Use: From the operator input screen select “zero speed” operation. P521 should read 4 ma or slightly
less and motor speed should be zero. Now turn on any valve. P521 should read a higher value at 3
GPM and should increase depending on the flow set on the HMI. If this does not happen, check the
wiring from the drive to the PLC, the connectors on the PLC for proper installation and look for a
fault light on the PLC.
P540 Total Run Time. Indicates total hours the drive was enabled (ready to run.)
P541 Total Power-On Time. Indicates total hours the power was applied to the drive.
Use: Use in conjunction with the next three parameters to analyze the fault history.
FAULT HISTORY: Using the parameters P550, P551 and P552 it is possible to see how many faults have
occurred and at approximately what time. The fault logs are designed to avoid “overflow” resulting
from repetitive faults such as low buss faults caused by normal power down cycles. Refer to table 1
for interpretation of fault codes.
P550 Fault History. Shows the last eight unique faults. Press the up and down arrow keys to scroll
through the list of faults.
Format is n.xxx where n=fault number (1…8) with 1 indicating the newest fault. xxx= the three letter
fault code from table 1
P551 Fault History Time. Format is n.hhhh, mm, ss = fault number, hours, minutes, seconds
P552 Fault History Counter. This parameter indicates the sequential occurrences of a fault.
For example: The line voltage dips below minimum which will cause the drive to trip off line due to a
low bus voltage.
HydraSmart Power Unit Page 19
Motor Drive Trouble Shooting Tips (Continued)
If this happens three times over a period when there are no other faults, P552 will indicate 3, P550 will
indicate the fault “LF” and P551 will indicate the time counted from the first time power was
applied. Note that only the time of the first occurrence is displayed. The time of faults two and
three are not known unless another fault occurs, then you will know that the 2nd and 3rd occurrences
were between the time of the first fault and the next new fault displayed in P550.
FAULTS CODES: The drive is capable of displaying over 25 fault codes. Only the most likely or those that
you may be able to clear are listed here. If you see any other code, write it down and call for service.
TABLE 2 - FAULT CODES
F_AF HIGH TEMPERATURE Ambient temperature is above 95F. Fan filter is dirty.
F_EF EXTERNAL FAULT There may be a problem with the external wiring or braking resistor unit (on HS20 units only)
F_dbF DYNAMIC BRAKE UNIT FAULT (on HS20 units only) Check for high line voltage, Replace unit. Call for service.
F_LF LOW BUS VOLTAGE Check for low line voltage.
F_HF HIGH BUS VOLTAGE Check for high line voltage.
F_OF OUTPUT FAULT Shorted output/Check motor wiring. Shorted output transistors/call for service
F_OFI GROUND FAULT Check motor leads for shorts to the chassis.
F_PF MOTOR OVERLOAD Extended period of high motor load. Check flow and pressure settings against max. permissible values
F_SF SINGLE PHASE FAULT Check line voltage for missing phase.
HydraSmart Power Unit Page 20
PLC Trouble Shooting Tips
The PLC is located in the lower part of the enclosure with the drive. It has green connectors on the front
along with a series of red or green LED lights. The connector on the upper left of the unit contains
the input wiring and the LED lights to the right of this connector represent the state of the adjacent
input. Inputs are designated by the letter “X.” If the light is on, the input is active (24 volt power is
applied).
The connector immediately below that one is the output connector and the lights indicate whether or
not the output is turned on. Outputs are indicated by the letter “Y.” The connector on the far right
module (HydraSmart units with add-on features such as extra valves may have a third module)
contains the analog outputs to the motor drive and to the pressure controlling servo valve on the
manifold. The analog current outputs are marked “I.”
By using the schematic for the unit and watching the lights on the PLC, important troubleshooting
information can be determined.
For Example: your machine is calling for solenoid SV1 to be on, then the lights on X4 and Y2 should be
on, as well as the light on CR1, which is located near the PLC.
Other Lights: Also, in the upper left corner of the PLC module are three more lights, Power, Run and
Error. When power is connected to the machine the POWER light should be on as well as the RUN
light. If neither is on, check the circuit breaker for the 24 volt power supply, CB3. If only the power
light is on, verify that the small slide switch below the lights, marked RUN is in the run position. If it
is, try cycling the power to the machine. Also, if the ERROR light is on, look at the two plugs on the
bottom of the PLC and be sure that both plugs are seated properly. Cycle the machine power. If the
error light remains on, call for service.

OPERATION:
1. On the operator station, enter the maximum pressure and flow that may be required for the
particular system connected to the manifold.
2. Control the actual pressure delivered to the cylinder with the pressure control valve for the circuit
desired. Use the gauges provided to determine actual pressure. NOTE: turning the adjustment screw
counter clockwise decreases pressure and clockwise increases pressure.
3. Control the flow to the circuit by using the individual flow control valves and watching the speed of movement of the load while turning the adjustment screw. NOTE: Clockwise reduces the flow and counter clockwise increases the flow. EXAMPLE: a. A cylinder has been connected to ports A1 and B1. Maximum required pressure has been estimated at something less than 1500 psi and maximum flow as 13 GPM. b. As a rule of thumb, always set the system pressure more than 100 psi above the anticipated manual set point to avoid valve oscillation. Therefore, Set the system pressure on the HMI to 1600 psi or higher and the flow to 13 GPM or greater and start the pump. c. Cycle the cylinder and adjust the pressure to insure smooth travel of the cylinder in both directions. d. Now, adjust the speed of travel in each individual direction using the flow controls as required. e. If satisfactory operation cannot be attained, it will be necessary to go back to the operator panel and increase either the pressure or the flow. NOTE: always using maximum settings on the control screen will generate unnecessary heat and noise. PRESSURE RELIEF: For safety and convenience, when disconnecting hoses or for testing purposes, the pressure within the cylinders and hoses may be released and bled to zero by opening the check valves located on the manifold body. NOTE: Turning the adjustment screw counter clockwise will relieve the pressure in the hoses, but for the system to operate normally, the screws must be at the maximum clockwise position.

ADDENDUM B
Instruction For The Use Of The Hydrasmart Multi-Valve Add On Kit.
Introduction: The multi-valve add on kit provides multiple sources of hydraulic power in addition to the
normal bi-directional axes of power provided by the basic HydraSmart unit. The add-on valves are
powered by a 24 volt D.C. signal that is supplied by a separate source other than HydraSmart unit.
This auxiliary manifold may be mounted on the HydraSmart unit or located remotely. Illuminated
valve connectors are provided for easy troubleshooting. Variable pressure and flow controls are
provided for each port along with separate bleed valves, one for each output port, to relieve
trapped pressure.
Installation
If the auxiliary manifold is to be mounted separately, plug the multi-pin connector from the auxiliary
manifold into the junction box located on the rear of the power unit and plug in the extension feed
hoses to the quick disconnects provided on the power unit and the auxiliary manifold.
Operating Instructions (refer to “Controls Layout” section and Figure 1B on the next page)
On the HydraSmart operator control HMI, Set the pressure and flow as required for the bi-directional
valves on the HPU. The pressure and the flow must be equal to or greater than the pressure and
flow required at the auxiliary outputs. With the pump on, adjust the pressure reducing valve (PCn)
to set the desired pressure for each pair of outputs using the gauge provided. Now set the flow, as
required for each port, using the flow control valve for each port. Use the manual override on the
valve coils to open and close the valves to test.
To relieve the pressure in the output lines, turn the pump off and open the appropriate dump valve.
WARNING: Motor will be overloaded if any dump valves are open during operation!
Be sure to close (clockwise) all open valves again to return to normal operation. Note: when using the
“Multiset” feature on the main unit, it is possible to open any number of gate valves at the standby
pressure and flow settings, and then close the ports before the machine valve opens at the new
multiset level. The auxiliary pressure will then be maintained in each port by the check valve
located in the auxiliary manifold.
