ERROR CH5/6 (red) This LED lit up in c ase there are problems with operating the Zoom or Focus of the Lens. T his is
caused by over-current or over-temperature of the driver. Possible problems are:
• the electrical socket of the Lens or Lens Holder are dam aged (short circuit).
• the wire unit between Motor Control Board and Lens Holder socket is dam aged (short c ircuit).
• the mounted Lens is m alfunctioning.
6
ERROR CH1 (red) This LED lit up in case there ar e problems with the horizontal shift of the lens. Possible problems
are:
• the wire unit of the stepper motor for hor izontal shift is disconnected.
• the wire unit of the stepper motor for horizontal shift is damaged (causing a open circuit
or short circuit).
• the stepper motor for horizontal shift is malfunctioning.
7
ERROR CH2 (red) This LED lit up in case there a re problems with the vertical shift of the lens. Po ssible problem s are:
• the wire unit of the stepper m otor for ve rtical shift is disconnected.
• the wire unit of the stepper motor for vertical shift is damaged (causing a open circuit or
short circuit).
• the stepper motor for vertical shift is malfunctioning.
8
ERROR CH7/8 (red) This LE D lit up in case there ar e problems with operating the Shutter or Contrast plate of the
projector. This is cau sed by over-current or ov er-temperature of the dr iver. Pos sible problems are:
• the wire unit of the DC motor of the Shutter is damaged (causing a short circuit)
.
• the wire unit of the DC mo tor of the Contrast plate is damaged (causing a short circuit).
• the DC motor of the Shutter is malfunctioning.
• the DC motor of the Co ntrast plate is malfunctioning.
9
ERROR CH4 (red) Channel 4 is currently not used and thus this LED has no p urpose (future expansion)
10
FPGA CONFIG (red) This LED lit up during the start up of the Motor Control Board and in case the FPGA of the
Motor Control Board is not correctly loaded with the firmware. If this is the case try to reload the
firmware and/or software of the Motor Control B oard. If the problem remains replace the Motor
Control Board.
11 +3.3V OK (green) This LE D lit up in normal condition and indicates that the local generated +3.3V is available. Th e
+3.3V is derived from the +12V which is generated by the Pow er Box.
12 SWITCH FORCE
BOOT
Keeping this switch pressed while powering the projector will force the Motor C on trol Boar d to run
in bo ot mode. As a result the MCB HEARTBEAT flashes twice a second.
