TROUBLESHOOTING – LP WATER
5.3.1 Low Booster Pump Pressure
Booster pump pressure
below 70 psi
If at anytime the pump is running and the booster
pump pressure falls below 70 psi, adjust the relief
valve clockwise to increase the pressure above 70
psi.
If the booster pump pressure cannot be adjusted above
70 psi, replace the booster pump.
Booster pump pressure
above 125 psi
If at anytime the pump is running and the booster
pump pressure is above 125 psi, the relief valve is
opening up and sending water to the drain.
5.4
TROUBLESHOOTING – HYDRAULIC
5.4.1 Hot Hydraulic Oil
Restricted or No Cooling
Flow
Check cooling water flow to and from heat exchanger.
The water pressure differential across the heat
exchanger, 2.75 bar (40 psi) minimum required for
flow through the exchanger.
Check operation and setting of water modulating valve.
Water Modulating Valve
Setting
Check and adjust setting of water modulating valve.
Compressing spring (clockwise) slows water flow and
increases temp; reducing spring tension
(counterclockwise) increases water flow and lowers
oil temp.
Heat Exchanger Clogged
Flush heat exchanger, improve flow of cooling water or
replace heat exchanger.
Recirculation Pump
Hydraulic Pressure
below 20psi
Replace hydraulic oil filter.
If filter is new, replace recirculation pump.
5.4.2 Hydraulic Pressure but no High Pressure Water Pressure
Proximity switch failure
Verify left hand and right hand LED lights on
Directional Control Valve (DCV) alternately illuminate
ON/OFF. If so, both proximity switches are properly
functioning.
If both the green and red LED lights are on at the same
time on one proximity switch, replace the proximity
switch.
*Flag the proximity switches one at a time, checking to
see if either switch is sending a signal to the PLC.
