or exceeds the CONTACTOR COUNT ALARM setting. This serves as a method to perform
preventative maintenance on the contactor before a failure is likely to occur.

Procedure: Adjust the CONTACTOR ALARM setting to the desired value. Note that the
CONTACTOR ALARM must be enabled in order to adjust the CONTACTOR ALARM setting.
IMPORTANT: The CONTACTOR ALARM is only available if the SWITCH CONTROL MODE is set
to either DEADBAND or PROPORTIONAL AMBIENT CONTACTOR.
3.5.22 EEROM DATA FAILURE ALARM
Purpose: This alarm indicates that the control module has detected a failure in its non-volatile
memory. If this occurs, the control module may be uncalibrated because factory default values
may have been reloaded. This indicates an internal problem and the control module should be
replaced and returned to the factory for repair. The three-character display will always flash
“Err” when this alarm is active.
Alarm Mask: ENABLE or DISABLE
Procedure: Enable or disable alarming of a non-volatile memory failure as desired.
IMPORTANT:
• The EEROM DATA FAILURE ALARM should always be enabled.
• This alarm cannot be reset.
