Operator Response to LCD Error Indication Alarms
If an alarm occurs during operation, the controller will switch off the internal power to the heaters
and an appropriate error indication display will appear.
Pressing the RETURN button resets the error. If several zones display alarms, each must be ac-
knowledged by pressing RETURN. The alarm display is switched off. The operator must either
switch OFF the indicated temperature zone(s) (via the DynaControl keypad) or troubleshoot to cor-
rect the problem.
Low temperature alarms will not open the main contactor and are only indicated on the bar-graph
display and auxiliary alarm output contacts.
A sensor failure is displayed as a "?" on the bar-graph and power is switched off to the zone.
When the actual temperature exceeds the setpoint limitation plus a tolerance of a few degrees, a "!"
is displayed on the bar-graph and heater power is switched off.
