Possible reason of error
Instructions for trouble shooting
No temperature rise
No sensor connected, sensor defec-
tive
Check the connected sensors:
1) Remove connecting cable of Hot Run-
ner Controller
2) Measure resistance of sensor with
multimeter
3) Infinite resistance means, no sensor
existing or sensor defective
No temperature rise
Sensor wrong connected
Check the pin assignment of connecting
cable and of mold.
No temperature rise
Neutral conductor permuted
Check wiring system
Mains phase missing
The mains phase to control the power
output is not connected (case Yes) or
the appropriate fuse was triggered
(case No).
Open Hot Runner Controller. Flashes the
red LED on all power controller cards?
1) YES
1.1) Check main fuse and exchange de-
fective fuses
1.2) Check power cord
2) No, only on the appropriate power
controller card of the zone:
2.1) Switch-off power supply
2.2) Lock card
2.3) Red LED still flashing: exchange
power controller card
Measured current with
switched off heating
Power output defective
Exchange power controller card of the
appropriate zone.
No current measured
No heater connected
Check the connected heating element
1) Remove connecting cable of Hot Run-
ner Controller
2) Measure resistance of heating with
multimeter
3) "Infinite" resistance means, no heating
element found
No current measured
Power of the connected heating ele-
ment too low
In case of power value of heating zone
below 50 W (at 230V) no current measur-
able.
No current measured
Fuse defective
Check appropriate fuse for zone on pow-
er controller card and where necessary,
exchange it.
No current measured
Wiring error
Check wiring
