Manually Stroking QuickTrip (powered)
Manually stroking valve procedure:
1. In order to manually stroke the QuickTrip valve, the actuators must be powered with 24 Vdc. Make
sure the power supply is connected and operating while performing this procedure. This can be
verified by viewing the LED status through the sight window on top of the valve. One or two blue
LED’s indicate that the power supply is connected and is turned on.

Do not remove covers or connect/disconnect
electrical connectors unless power has been switched off or the area

QuickTrip may be manually tripped either by de-energizing the logic solver interposing relay to initiate
a trip state or by tripping the breaker to the Control In discrete input terminals on the QuickTrip
electronics module (terminals 5 and 6 of TB2).
3. If QuickTrip is in a trip state, as indicated by a red as LED viewed through the sight glass, QuickTrip
