5.1.1 Solenoid Valve Manual Override Procedure

Double solenoid valve adapters have manual override buttons on both lock and unlock side of the
valve. The manual override should only be used for unlocking the Tool Changer.
The manual override procedure should be used when the Tool Changer is locked without the Tool
plate attached. The control module safety circuit will not allow the Tool Changer to be unlatched
without the Tool plate attached and the tool in the tool stand.
Tools required: 3 mm Allen Wrench, 2 mm ball end Allen wrench (hex key)
1. Using a 3 mm Allen wrench, remove the M4 socket head cap screws, warning label, and nylon
washer from the Unlock side of the solenoid valve. The Unlock side is marked with a "U".
2. Insert a 2 mm ball end Allen Wrench in the unlock valve screw hole and gently depress the
valve override button. An air release should be heard when the solenoid is actuated. Make sure
locking mechanism is fully retracted.
3. Using a 3 mm Allen wrench, replace the M4 socket head cap screws, warning label, and nylon
washer and tighten the screw.

WARNING: Do not use the solenoid valve manual override if the tool is locked
to the Master. Using the manual override will release the Tool and may cause
bodily injury or damage to equipment. If the Tool is attached to the Master
it must be secured in the tool stand or in a location where the tool weight is
supported before using the manual override.
CAUTION: The manual override is not intended for normal operations. Manual
override is to be used in situation were no other alternative is available to
unlock the Master. Do not execute the Latch command unless the Master and
the Tool are ready to be coupled.
CAUTION: Applying excess force can damage the solenoid or cause override
button to stick in one position. Actuation of valve override buttons requires very
little travel (~1 mm) and only a small amount of force. Use non-sharp object,
similar to ball nose 2 mm Allen key, to gently depress the override button; an
air release should be heard when the solenoid is activated.
