Honeywell Honeywell Modulating Fluid Power Gas Valve Actuator V9055A 1055 V9055A 1055

Warning: Only trained personnel should perform this procedure

The actuator is not field repairable except for replacing the auxiliary switch

Do not disassemble the valve actuator

With manual gas valve closed, energize the V9055 and check for voltage on terminals 1 and 2. Actuator should modulate to the low-fire position

CAUTION! Equipment Damage Hazard. Improper wiring can damage the equipment and cause injury to personnel. Label all wires prior to disconnection when servicing valves. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing

Disconnect the leads from the modulating controller (terminals W,R, and B). Connect a manual potentiometer, color-to-color, to terminals W, R, and B on the actuator. With the valve energized, use the potentiometer to open and close the actuator. It should run from the low-fire position and to the fully open position

If the actuator itself has failed, return it to the factory for repair
