Basic Troubleshooting
Thermocouple (T/C) Open – The T/C connection is
broken, follow general troubleshooting
Thermocouple Reversed – The T/C connection is wired
+ to - at some point. Visually inspect each connection,
for type J US standard, red wire should connect to red
wires, not red to white
Open Fuse – Fuse on module bad. Turn "Off" main
disconnect. Locate module, check all fuses.
(Locate module light – press clear alarm button with
zone selected)
Shorted Heater – The heater is shorted or exceeds
the maximum rating of the module, follow general
troubleshooting
Open Heater – The heater connection is broken,
follow general troubleshooting
Clear alarm, turn off light / external relay. Press to
illuminate "find this module light" on zone
selected for 15 seconds
General Troubleshooting – Turn "Off" Main Disconnect
1
Check resistance from pin to pin, at the mold. T/C should read 3-50 ohms at
room temperature. Heater should read greater than 8 ohms. If there is no
continuity (open line) = broken connection, open heater or open T/C
2
Check resistance from pin to ground, at the mold. Heaters only – no continuity
(open line) = good. Some resistance is bad, heater shorted
3
Reattach the cable to the mold, detach the cable from the controller. Check
resistance from pin to pin on the cable. T/C should read 3-50 ohms at room
temperature. Heater should read greater than 8 ohms. If there is no continuity
(open line) = broken connection, open heater or open T/C. The connection is
broken in the cable set or the connectors/pins are not making contact
4
Reattach the cable to the mold, detach the cable from the controller. Check
resistance from pin to ground on the cable. Heaters only – no continuity
(open line) = good. Some resistance is bad, heater shorted. The wires are
either shorted in the cable set or the connectors are shorting to ground
5
At this point if everything is fine, the problem is in the controller. (1) turn "Off"
main disconnect, (2) locate problem module, (3) check fuses on module,
(4) swap bad module into a known good location, (5) turn "On" main
disconnect, (6) test the zone. If the problem follows the module = bad module.
If the problem stays with the original zone, the error is between the module
and the connectors on the rear of the enclosure. If available, try replacing the
T/C input module for that module or the data concentrator (communications
module) for that module

Alarm Area
High Temperature (+20ºF/11ºC default) – The temperature of
the zone exceeds the deviation band in advanced setup
Low Temperature (-20ºF/11ºC default) – The temperature of
the zone is below the deviation band in advanced setup
Thermocouple Pinched – The T/C is pinched or the
controller thinks it is pinched. (Default: 98+% output,
must see +20ºF/11ºC in 5 minutes). True pinch – the T/C
is sensing the temperature further away from the heat source
than intended. Without alarm, temperature reads low, controller
applies power, runaway heat. False T/C pinch – heater is too
small to heat the zone or the T/C is located too far away.
Replace heater; move T/C or adjust alarm. Selectable detection
times in advanced setup
Uncontrolled Output – The module has an unregulated output.
All zones on module shut "Off" automatically
When the high temperature alarm is also illuminated (flashing),
the critical over temperature alarm has been activated
