Shutdown Errors
Shut Down Error Description
Abort Over Temp A zone's actual temperature has exceeded its setpoint by the
amount set for the abort limit.
Abort Under Temp A zone's actual temperature has dropped below its setpoint by
the amount set for the abort limit.
Configuration Each zone’s control parameters are compared to the values sent
and received by each zone. If the values differ, then the system
will automatically correct the problem. If the problem is not
corrected after one minute, then the configuration alarm is
triggered.
Circuit Overload The over current hardware signal is triggered by the current
sensor. This error occurs immediately: usually in a dead short
situation.
Control Card Over Temperature A control card temperature has exceeded 76 °C (170 °F).
Earth Leakage ICC
2
: If the calculated limit or default value is exceeded, the earth
leakage error is triggered.
ICC
3
: If the measured leakage level exceeds the Earth Leakage
Fault Limit value, the earth leakage error is triggered.
Fuse 1 Blown Fuse 1 on this Intelligent Control Card (ICC
2
or ICC
3
) has blown
and needs replacing.
Fuse 2 Blown Fuse 2 on this ICC
2
or ICC
3
has blown and needs replacing.
Lost Thermocouple This zone has a defective or open thermocouple.
Maximum Temp Limit The temperature on this zone has risen above the maximum
value allowed. This usually means the switching device has failed
in the closed position and the zone ran away. The factory setting
is 95 °C (200 °F) over the normal setpoint.
No Response The system has been applying 96% to 100% power to this heater
for a set amount of time, and the thermocouple connected to this
zone is not responding. The thermocouple may be pinched or
the heater power wires may be broken.
Over Current Limit The current on this zone has risen above the maximum value
allowed.
Receive Data Comm This zone has stopped receiving data.
Rev. Thermocouple The positive and negative leads from the thermocouple have
been switched or the connections are reversed. As power is
applied, the temperature goes down instead of up. Correct this
situation at the point where the wires are reversed.
Read Time Out This zone has stopped transmitting data.
