Abort Conditions (Shut Down Errors): 81
User Guide v 1.4 — September 2015 System Setup and Customization
9.5.5.2 Abort Conditions (Shut Down Errors):
The following conditions will cause the audible and visual alarms to initiate. Since they are
Shut Down Errors, they will cause the system to shut down and remove power to the heaters.
Table 9-6 Abort Condition Descriptions
Abort Condition Description
ABT OVER Over Temperature Abort. A zone's actual temperature has exceeded its
setpoint by the amount set for the abort limit.
ABT UNDER Under Temperature Abort. A zone's actual temperature has dropped
below its setpoint by the amount set for the abort limit.
FUSE 1 Fuse 1 Blown. One of the heater protection circuits (fuses) has been
blown. It is necessary to replace it. Refer to Section 12.2.3.
FUSE 2 Fuse 2 Blown. One of the heater protection circuits (fuses) has been
blown. It is necessary to replace it. Refer to Section 12.2.3.
NO RESP No Thermocouple Response. Neo2 has been applying between 96% and
100% power to this heater and the thermocouple is not responding. The
thermocouple may be pinched or the mold could be mis-wired.
LOST T/C Lost Thermocouple. This zone has a defective or open thermocouple.
REV T/C Reversed Thermocouple. The positive and negative leads from the
thermocouple have been switched or the connections are reversed. As
power is applied to the heater, the temperature decreases instead of
increasing. The operator must correct this situation at the point where
the wires are reversed.
EARTH LEAKAGE Earth Leakage. This zone has current flowing greater than 3 Amperes to
ground (earth) and there is potential for a short circuit.
OVER MAX Over Maximum Temperature. 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 200 °F over the normal setpoint.
OVER CRNT Over Maximum Current. The current on this zone has risen above the
maximum value allowed.
NO HEATER This zone is not showing any current draw. This usually means there is
not a heater hooked up to this zone or the wires to the heater have been
severed.
CC RX COMM Control Card Receive Communications Error. This zone has stopped
receiving data from the Neo2 operator interface.
CC TX COMM Control Card Transmit Communications Error. This zone has stopped
transmitting data to the Neo2 operator interface.
CC MAX TEMP Control Card PCB Over Temperature. The temperature sensor on the
control card is reading too high, this means the PCB is running too hot.
A possible cause could be that one of the system fans has stopped
working.
