Ground Fault Bad heater.
Short in wiring.
Bad Card.
Mis-wired mold, cable or controller.
Moisture in the heater.
Consult the mold electrical prints and use an
ohmmeter or insulation resistance meter to
inspect the cables and mold.
This is unlikely to be a controller issue but the
connectors on the back of the controller
should be inspected as well.
Swap the card with a known good unit and
confirm if the error returns. If not, replace the
card.
If moisture is suspected, place the zone
setpoint at a 200°F (93°C) and apply heat until
the moisture has been baked out of the
heater.
No Response Heater is not heating sufficiently (Undersized
or low input voltage).
Temperature of the heater cannot be sensed
(Pinched or displaced thermocouple).
Insufficient heat can be low supply voltage.
Check the supply voltage and confirm that
this mold has run successfully at the present
voltage. If not, connect the controller to a
supply with sufficient voltage.
In some cases the current reading may be
used to determine if current is flowing
through the heater. If no current is flowing, a
wiring fault or bad heater is likely.
Shorted, detached, mis-positioned or pinched
thermocouples are possibilities. Check the
cables and wiring in the mold to ensure
thermocouples are properly routed and
terminated.
Reverse T/C Thermocouple has been connected with
reversed polarity.
Card is not calibrated.
Card is nonfunctional.
Mold is much colder than ambient.
Insufficient heat can be low supply voltage.
Check the supply voltage and confirm that
this mold has run successfully at the present
voltage. If not, connect the controller to a
supply with sufficient voltage.
In some cases the current reading may be
used to determine if current is flowing
through the heater. If no current is flowing, a
wiring fault or bad heater is likely.
Shorted, detached, mis-positioned or pinched
thermocouples are possibilities. Check the
