Alarm Manual/Automatic Reset Option

Units incorporating alarms are shipped set for automatic alarm: i.e.,

the alarm relay resets automatically when the pressure drops back

below the setpoint.

If manual reset is desired, remove the factory installed jumper

between terminals 4 and 5 (Reset) on the terminal block. Replace

jumper with a normally open pushbutton between the two terminals.

Units equipped with alarms are adjustable to provide either a Hi or

Low alarm setting. Units shipped from the factory are set for "Hi"

alarm, i.e., alarm relay trips upon ascending pressure. To modify unit

for a low alarm, remove gauge face per Figure 5. Remove Jumper on

signal conditioning board and reinstall per Figure 10.
