Alarm Condition Description
ALM OVER Over Temperature Alarm. A zone's actual temperature has exceeded its
setpoint by the amount set for the alarm limit.
ALM UNDER Under Temperature Alarm. A zone's actual temperature has dropped
below its setpoint by the amount set for the alarm limit.
A-SLAVE Lost Thermocouple, Auto Slave activated. A zone has had its
thermocouple become defective while running in automatic control
mode. The system has AUTOMATICALLY SLAVED this zone to another
one using data collected before the thermocouple became faulty. The
faulty zone is now being controlled by the power output from another
similar zone. Once a zone is Slaved, the auto-slaved zones number on
the Home screen will switch between the slaved zone number and the
master zone number.
AMC-NO T/C Lost Thermocouple, AMC activated. A zone has had its thermocouple
become defective while running in automatic control mode. There was
no match found for this zone in the mold by the Auto-Slave feature. The
zone has been setup to go into AUTOMATIC MANUAL CONTROL in this
event. The zone is now being controlled in manual mode at a power
percentage selected by the controller using data it collected before the
thermocouple became faulty.
