Alarm Conditions / Temperature Alarms
If the readings are within the alarm limits, the STATUS LED will blink green.
When the temperature reading meets or exceed the temperature limits the STATUS LED will
blink red.
After the probe’s alarm delay time is exceeded the unit will blink the ALARM LED and beep the
buzzer.
The user can MUTE the buzzer by tapping the MUTE/MENU button. The unit will reduce the
audible signal from a loud beep, to a quieter and less frequent chirp. It will remain muted until
MUTE time expires or a different probe goes into alarm.
Once the Alarm state has been signaled the unit will wait the appropriate Relay Delay(s) time
before tripping the appropriate Relay(s). Units with individual channel relays, have individual
Relay Delay times. Units with a single relay have one Relay Delay time that applies to any
alarm condition.
