DISPLAY
The unit's display shows the current temperature, the alarm set point temperature, the alarm
state, and the mode of operation of the unit (over temperature or under temperature alarm).
The TA22 Temperature Alarm is a single point or threshold type of temperature alarm.
This type of temperature alarm monitors the temperature at the sensor probe tip and when this
temperature passes above (or below) the set point, the unit will execute a preset operation.
NOTE: This unit also has a concealed slide switch that allows for the alarm to be activated
immediately when the temperature has met the alarm threshold, if desired.
When the probe temperature reaches the set point, the unit will display its state as follows:
·
In delayed alarm state the
ALARM
icon and the Bell will flash.
·
In the alarm state the
ALARM
icon and the Bell will remain solid. The Bell clapper will flash.
Audible alarm will sound and the N.O. relay contacts will close.
·
If the Silence button is pressed during alarm condition, the audible alarm will turn off and
the N.O. relay contacts will open.
