Alarms
The M&C Series TEC1 comes equipped with a Form C dry contact alarm relay to indicate the status of the
chiller. The relay operates in failsafe mode, meaning the coil is energized when there are no alarms present. As
this relay is a general status alarm, the following alarms, listed in order of severity, will cause the coil on the
relay to de-energize. Only the alarm with the highest severity will be written to the controller's display, listed in
the following order:
• High Temperature, channels #1 thru #4
• Low Temperature, channels #1 thru #4
• Open Thermocouple, channels #1 thru 4
• Water Slip, channels #1 thru 2
• Power Supply (general purpose unit only)
