Adjusting Belt Tensions

Over time and with repeated use, belts may loosen. Belts that are too loose may cause the

fixture to calibrate incorrectly and may affect the movement or repeatability of the motorized

mechanisms. Follow all belt adjustment procedures carefully to insure optimum operation

of the Revolution luminaire.

Adjusting Tilt and Pan Tension

Adjusting tilt belt tension:

Step 1: Power-down the fixture. See Power-down Procedure, page 9.

Step 2: Using a #2 Philips screwdriver, loosen the four captured screws on the tilt-side

yoke cover and remove the cover. The tilt-side has the tilt lock mechanism

protruding through the yoke cover.

Step 3: Loosen, but do not remove, the four screws securing the tilt motor assembly to

the yoke leg.

Step 4: Pinch the tilt belt together a few times to adjust the motor placement. Allow the

motor to settle against the spring. Make sure the spring is centered on the plate.

Step 5: Tighten the motor screws in a star pattern.

Step 6: Place the yoke cover back on and tighten the captured screws.
