Touch Screen Error Indication Faults & Alarms
If a fault/ alarm occurs, the Acknowledge button (on the Main Screen) and the temperature zone
will be highlighted in red. The controller will turn off the internal power to the heaters and an ap-
propriate alarm indication will appear in the status line of the controller’s display.
The operator must either turn Off the indicated temperature zone(s) or troubleshoot to correct the
problem. Then press the Acknowledge button in order to turn on the main contactor and reset the
error. If more than one alarm condition occurs simultaneously, the alarms will be displayed se-
quentially and each alarm must be acknowledged.
When an alarm occurs, the current display will be interrupted only if a sensor (or a motor drive)
failure has occurred. When the actual temperature exceeds the setpoint limitation (plus a toler-
ance) the over-temperature alarm is displayed and main power is switched Off.
