Installation, Operation & Maintenance Manual
NOTE:
TROUBLE SHOOTING
It is assumed that the system has been installed in accordance with the proper instructions, that all wiring is correct
and that power to the system is as specified on the controller.
Normally problems have two basic forms:
First, relate to the Controller, Wiring, Heaters or Thermocouples. These problems usually present themselves as
abnormal indications on the control module, i.e., absence of or blinking lights & displays and error codes.
Second, revolve around the design and/or manufacturing of the mold, the hot runner system (manifold), or the actual
processing conditions. These problems are often difficult to identify and repair.
PROBLEMS:
SOLUTIONS:
The module will not turn on:
1. Check input power.
2. Ensure input power is in proper phase.
3. Check power cord connections.
4. Check that main frame is turned on.
5. Check fuses (Bussman ABC-15), if blown check
for wiring short.
6. Swap module with known good module.
7. Return defective module for repairs.
Temperature won’t settle on set point:
1. Give module more time to settle on set point.
2. Molding process may have a wide variation in
temperature. Check to see if changes in display
temperature are in the same cycle as molding process.
Lights dim:
1. Check actual input voltage, should be same as
module rating.
Module appears to operate properly, but no power
1. Main frame is not set up for Anti-arcing.
is being applied to the heater:
2. Move jumper from pin position #2 & #3 (Enabled)
to pin position #1 & #2 (Disabled).
Mold is unusually cold:
1. Allow tool to warm up in Soft Start mode.
2. Check mold thermocouple/heater wiring.
3. Thermocouple/Heater not wired to proper zone.
4. Thermocouple/Heater defective.
5. Make sure input power voltage is correct.
6. Return defective module for repairs.
Temperature above set-point:
1. Thermocouple shorted or not wired correctly.
2. Triac shorted.
Tool overheats:
1. Is temperature display set to F
o
?
2. Check thermocouple.
3. Replace triac.
4. Return defective module for repairs.
Open thermocouple:
1. Check thermocouple & mold wiring.
Reversed thermocouple:
1. Correct thermocouple mold wiring.
