15.12.1MoldCheck Trouble Shooting
After the complete diagnosis of electric conditions of the hot runner and the corresponding peripherals by the func-
tion MoldCheck, references for trouble shooting are given for the erroneous zones. The MoldCheck references for
trouble shooting are presented as follows:
By the shown help key the user could display further notes for trouble shooting.
Identified faults in header Possible reason of error Instructions for trouble shooting
Short circuit
Power of connected heater is higher
than connected load of output.
Check wiring of sensor and heating on
permutation.
Control heater.
1) Remove connecting cable of mold
2) Measure resistance of heating with
multimeter
3) Read power value off table in Operat-
ing Instructions Hot Runner Controllers
and compare it with the connected value
of the heating output
Short circuit Short circuit on power output
Check feed line for short circuit.
1) Remove connecting cable of Hot Run-
ner Controller
2) Measure resistance at terminal with
multimeter
3) For resistance equals 0 Ohm fault in
cable or feed line of heating in mold
3.1) Remove connecting cable of mold
3.2) Measure resistance with multimeter
3.3) For resistance equals 0 Ohm fault in
feed line of heating in mold.
Residual current
Insulation resistance of heater too
low, e.g. by humidity in heating ele-
ment Single zones - execute MoldCheck
again. Where fault continues to exist, ex-
change heater.
Potential error at sensor input
Measurement signal for sensor input
too big.
Check the wiring and the state of the
heating element concerning conductive
connection between heater and sensor.
Temperature rise in spite of
switched off heating
Power output defective Check actuator card
