2) Select “Alarm 1” to set the level at which Alarm 1 will be activated (typically 10% of full range).
3) Select “Alarm 2” and set the level at which Alarm 2 will be activated (typically 20% of full range).
4) Select “Alarm 3” and set the level at which Alarm 2 will be activated (typically 50% of full range).

dependent on the current state of the button. When activated, these buttons will turn from gray to blue.
The button labeled ‘ASC/DES’ will set the sensor alarm for ascending (ASC) or descending (DES)
respectively. The button labeled ‘LAT/N-L’ will set the sensor alarm for latching (LAT) or non-latching
(N-L) respectively. Set the appropriate values for each alarm respectively:
value rises above the value set for that Alarm (Ascending). When de-activated (gray), the ‘DES’
button will cause the associated Alarm to activate when the sensor value falls below the value set for
that Alarm (Descending). Set Alarm’s 1, 2, and 3 to either ascending or descending.

allow that Alarm to reset until the cause is cleared or removed and the Alarm is reset with the reset
button. When de-activated (gray), the ‘N-L’ button will cause the associated Alarm to be reset when
the cause of the alarm is either cleared or removed. Set Alarm’s 1, 2, and 3 to either latching or non-
latching.

Bank Selection boxes will assign each sensor to a bank of alarms. Assigning a sensor to a Bank of alarms
allows the operator to create groups of sensor Alarms. When activated (Green) the sensor will be assigned
to the bank selected. I.E., selecting Bank 1 will assign that sensor to Bank 1; therefore, should an alarm
occur, it triggers the appropriate alarm in Bank 1 only.
