A zoom lens motor appears to have no power during calibration or operation
Details: The Zoom Controller PCB has four (4) motor drivers. There is a 2 Amp Timed (Slo-Blow) Fuse to pro-
tect each of the four drivers. They provide power for both the motors. The silkscreen on the Motherboard PCB
has each mechanism identified near the driver for each of the three Wheel Controller PCBs and the Zoom
Controller.
Procedure: If during calibration or operation, you observe a mechanism servo motor or stepper motor that
appears to have no power, locate the the driver for that motor. Verify all cables are installed properly. With
power off, visually inspect the driver for damage. If the driver chip has visible damage, then replace the driver's
PCB. If not, carefully remove the fuse. Check for continuity to determine if the fuse is open. If the fuse has
blown, then inspect the mechanism for shorts or other problems. Replace any blown fuses and recalibrate the
fixture.
Solution: Replace 2A Fuse...

Menu Display Issues

If power is applied and the Menu Display Touchscreen does not come up or the fixture does not start
the calibration routines
Details: The Interface/LVS Module controls several functions. It contains the 24VDC LVS that provides the low
voltage power for all the electronic components in the fixture, with the exception of the Ballast. It contains the
Master Control PCB that runs the Menu Touchscreen user interface and controls the DMX and Ethernet com-
munications. In addition, it generates the communication data that controls and monitors all the internal mech-
anisms if the fixture. When power is applied to the fixture, the LVS will supply 24VDC to all the mechanisms.
Next the MCB will display the Menu fixture status, detect the external communication, and initiate the internal
communication bus that starts the calibration routines for every mechanism in the fixture.
Procedure: If power is applied and the Menu Display does not come up or the fixture does not start the calibra-
tion routines, the most common cause will be a lack of 24VDC from the LVS. Remove the Pan-Side Yoke

If you do not have 24VDC, replace the Interface/LVS Module.
Solution: Replace Interface/LVS
If power is applied to the fixture and it begins to calibrate Pan and Tilt, but you do not see any status
information come up on the Menu Display Touchscreen
Details: The Interface/LVS Module controls several functions. It contains the 24VDC LVS that provides the low
voltage power for all the electronic components in the fixture, with the exception of the Ballast. It contains the
Master Control PCB that runs the Menu Touchscreen user interface and controls the DMX and Ethernet com-
munications. In addition, it generates the communication data that controls and monitors all the internal mech-
anisms if the fixture. When power is applied to the fixture, the LVS will supply 24VDC to all the mechanisms.
Next the MCB will display the Menu fixture status, detect the external communication, and initiate the internal
communication bus that starts the calibration routines for every mechanism in the fixture.
Procedure: If power is applied to the fixture and it begins to calibrate Pan and Tilt, but you do not see any sta-
tus information come up on the Menu Display, most likely the Display or MCB have failed and you will need to
replace the Interface/LVS Module.
Solution: Replace Interface/LVS
