Problem conditions
Fill out the problem conditions starting with the first question and working
your way to the end. When a question requires you to check a separate Unison
component, you will be directed where to go and what to do by the
instructions.
1. Are the wall stations working? Most problems with an architectural
lighting control system are detected when a control station won’t work.
Preset Recall and Fader stations have built-in feedback features that can
tell you a lot about what is happening in your system.
▼ Do the stations control lights? Press several different Preset buttons or
vary zone light intensities with the Zone or Master faders. Observe if
the light intensities change normally.
▼ Do station button and fader LEDs turn on/off properly? To test a Preset
button LED, watch it while you press the button. If the LED was off
when you pressed the button, it should turn on. If the button LED was
on, it should turn off. Try this with different Preset buttons to determine
if their LEDs are responding properly. To test fader LEDs, press
[Manual]. The fader LEDs should turn on. Press [Manual] again and the
LEDs should turn off.
▼ Do wall station LEDs run the self test chase? Push a button on a Preset
Recall or Fader station. Under some conditions, these stations respond
by turning all their button and fader LEDs on and off one at a time. This
is the self test chase. Pushing another button, or the same button again
will repeat the chase. When stations run the self test chase, it indicates
the station has lost its connection to the Architectural Processor.
▼ Do wall stations appear to be off (no response)? Pushing buttons and
moving faders on an unresponsive station will not change light
intensities or turn LEDs on or off.
