Power Failure
The KNIGHT 2 can be retracted manually if power to the unit is lost. If power loss is
temporary, reestablishing power may be easier than manually retracting the light.
Note: Disconnect power source from the KNIGHT
2
before manual operation.
Rotate to center
Locate the belly plate on the bottom of the lift arm and remove it by loosening all 4 screws
and only removing 2 of them. Disconnect the Red/White and Brown wires from one side of
the connecting terminals using a small flat blade screw driver.
Slowly apply pressure to the lamp tree to manually rotate to the centered position. Trying to
rotate too quickly or with too much pressure can break the rotation motor shaft. Be certain
that you rotate in the proper direction; the upper stage can rotate a full 360˚. Generally, you
need to rotate the lamp tree in the direction that requires the least amount of travel in order
to reach a centered position. If manual rotation causes the rotation belt to slip, this is alright
if minimized. Excessive slippage on the belt may cause enough damage for the need of belt
replacement.
Retract the lower stage
Slowly apply pressure to the rotation platform to manually rotate to the centered position.
Trying to rotate the platform too quickly or with too much pressure can break the rotation
motor shaft or cause the toothed drive belt to shear a tooth. The upper stage can be rotated in
either direction.
Generally, you need to rotate the platform in the direction that requires the least amount of
travel in order to center the platform.
Support the mid-plate assembly with temporary blocking to relieve the tension on the lower
actuator pivot pins.
Using a small flat blade screw
driver, remove the retaining rings
that secure the lower pivot pin in
place. New retaining rings must be
installed before returning light to
service.
Use a brass drift punch to remove
the pivot pin from the extension end
of the actuator. Avoid using a
hardened steel punch which could peen the end of the shaft thus damaging the bore within
the aluminum pivot blocks.
