If power is applied to the fixture and calibration completes, and you can see the Status for the mecha-
nisms displayed on the touchscreen, but you have no external control of the fixture
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 calibration completes, and you can see the Status for the
mechanisms displayed on the touchscreen, but you have no external control of the fixture, it is most likely a
MCB failure. When you have valid communication to the fixture, a green LED will be present on the front panel.
If you remove the DMX or Ethernet cable controlling the fixture from the data input on the front panel, the LED
will turn red. If you have known-good DMX or Ethernet, but no green LED, the MCB has failed and you will
need to replace the Interface/LVS Module.
Solution: Replace Interface/LVS Module...page 69

Pan/Tilt Issues

Tilt continues to move past center during calibration, and...
"TILT: no sensor" is displayed in Status Log and TLT sub-code is red
Details: During initial Pan/Tilt calibration at power-up, Tilt will line up between the yoke legs and Pan will rotate
looking for its mechanical stop. If Tilt continues to move past the center, it is an indication that the COT sensor
has failed or is unplugged from the Pan/Tilt Controller PCB. In addition, the Status Log will display the error
"TILT: no sensor" and the TLT sub-code will be red.
Solution: Re-connect Pan/Tilt COT Sensor Cable.
Solution: Replace Pan/Tilt COT Sensor... page 74
PAN sub-code is red and Status Log contains one or more Pan-related error codes, and/or...
TLT sub-code is red and Status Log contains one or more Tilt-related error codes
Details: Upon power-up, the Pan/Tilt Controller PCB performs a calibration procedure that the Pan and Tilt
must pass before allowing control of these two functions. The Tilt moves to a position between the two yoke
legs and stops. The Pan rotates the yoke until it contacts the pan stop and reverses directions for half a turn
then stops. The Status screen will show the PAN and TILT sub-codes in green if they pass. If the Pan/Tilt Con-
troller PCB is faulty, or if either mechanism fails, the sub-codes will appear on the Status screen in red and
there will be one or more entries in the Status Log containing an error message.
Procedure: Remove the Pan-Side Yoke Cover (page 8) and verify all connections to the Controller PCB are
secure. If all connections are good, and the Pan and/or Tilt still fail, replace the Pan/Tilt Controller PCB with a
tested "known-good" PCB. If the failures continue, follow up on the error codes to isolate the source of the fail-
ure. If the failures stop, replace the Pan/Tilt Controller PCB.
Solution: Replace Pan/Tilt Controller PCB... page 73
