Trouble Shooting

Problem

Possible Cause

Remedy

Control unit reads high opacity

1- Smoke

2- Alignment is out

3- Transceiver and/or retro
window is dirty

1- Correct process

2- Adjust alignment until centered on
target.

3- Clean windows.

Control unit reads 100%

Transceiver current loop to
the control unit is open

Check wiring for open from Terminal
0V & I6 on control unit to wire 9 & 8
at J-box location.

Alignment is good but control unit reads high
opacity.

1- Reference voltage TP-2
on signal processor 1667 is
lower than 9.3V

2- Main lamp out

1- Adjust lamp drive PT-2 on the
power modulator 1668 until
Reference voltage TP-2 on signal
processor 1667 is 10.0 Volts +/- .3v.

2- Replace main lamp assembly

Control unit reads High, lens clean, alignment
is good.

Dirt built up in flanges

Swing open transceiver & Retro.
Clean flanges with push rod.
