In Normal Run mode, the alarm will trigger if the probe reads a temperature equal to or above the high
temperature limit. The high temperature limit cannot be set above the operating temperature range of
the unit.
Lo (Low Limit)
When in Normal Run mode, the alarm will trigger if the probe reads a temperature equal to or below
the low temperature limit. The low temperature limit cannot be set below the operating temperature
range of the unit.
Ad (Alarm Delay)
The Control Center will not declare an alarm until the out-of-range state has continued for a specified
time (the “alarm delay”). This alarm delay time will prevent transient nuisance alarms. The alarm delay
time can be set for 0 to 30 minutes.
rd (Relay Delay)
If there is an alarm condition, the relay contacts will switch. The relay delay parameter allows the user
to set the amount of time delay from the start of the alarm condition to the time the relay contact
switches. This keeps the relay from switching during short “nuisance alarms”. The operator may set the
relay delay time for 0 to 30 minutes.
SIL (Alarm Silence, or Alarm Mute Time)
This parameter sets the number of minutes the beeper will “chirp” when the mute button is pressed
during an alarm condition. After the Silence Time elapses, if the alarm condition still exists, the beeper
will begin to sound at full volume again. This parameter can be set from 5 to 120 minutes.
