TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
REMEDY
Injection time too long or too short
1. Timer(s) TA and/or TB out of adjust-
ment
1. Adjust timer(s) TA and/or TB in con-
trol panel as needed
Hydraulic pressure sustains relief setting
pressure for more than 5 seconds
1. Moisture on extrusion die or inside
compression cylinder accumulating
during shut down period
2. Excess moisture in liquid CO
2
supply
(dew point above -60 ºF (-51 ºC)
1. Remove extrusion die, clean and dry
die and inside of compression
cylinder thoroughly and reinstall,
being certain to torque according the
procedures on page 4.12
2. Check liquid CO
2
supply dew point
Hydraulic cylinder does not move
1. Solenoid coil on hydraulic control
valve burned out
2. Rectifier board in hydraulic control
valve shorted
3. Hydraulic control valve or hydraulic
pilot valve spool jammed by foreign
particles
4. Limit switch defective or stuck
5. Hydraulic control valve or hydraulic
pilot valve damaged
1. Replace solenoid coil, check control
voltage (high or low voltage will
cause solenoid coil to burn out) - for
double solenoid valves, make sure
both solenoid coils are energized at
the same time
2. Replace
3. Disassemble hydraulic control valves
and hydraulic pilot valve, clean and
reassemble
4. Repair or replace
5. Dissemble hydraulic control valves
and hydraulic pilot valve, replace any
damaged parts and reassemble
Hydraulic pump does not deliver hydrau-
lic fluid
1. Hydraulic fluid level low
2. Closed or restricted hydraulic fluid
supply line to pump
3. Leak in fluid intake line
4. Fluid viscosity too high (especially in
cold conditions)
5. Pump rotation reversed
6. Pump broken
7. Pump coupling broken
1. Add hydraulic fluid to proper level
2. Check supply valve and/or strainer
or filter
3. Repair
4. Use hydraulic fluid with a lower vis-
cosity or install a low density immer-
sion heater suitable for hydraulic fluid
(contact Tomco for more information)
5. Correct pump rotation - Note: Contin-
ued operation of pump in wrong di-
rection can damage pump
6. Replace
7. Replace
