How To Use The Alarms, Chapter 7

WATLOW Series 922 User's Manual

Alarms

Clearing An Alarm Message

You can clear a latched alarm when the ACTUAL display value returns to

within the operating band. You do not need to clear, indeed, you cannot clear,

a non-latching alarm. A non-latching alarm clears itself as soon as the AC-

TUAL display value returns to within the operating band. There is a 3°F

switching differential.

An Alarm And The State Of The Alarm Relay

Simply stated, a flashing alarm on the 922 alphanumeric display indicates the

state of the alarm relay contacts. A flashing alarm means that when an alarm

condition is present (ACTUAL beyond an alarm limit), then the alarm relay is

de-energized.
