2.2.6 Setting the external OFF indicator
If the rotating switch is set to
OFF indicator (e.g. a flashing light). When the rotating switch is set to
(the flashing light comes on).
Determine the signalling contact input with the J8 jumper setting:

Indication of OFF
Indication of not-OFF
2.2.7 Setting the phase control voltage
The signalling unit has phase processing. If the phase voltage goes below 80 Vac, a signal is generated. If
desired, the phase control voltage can be adjusted for each phase with the potentiometers P1, P2 and P3.

2.2.8 Setting the battery voltage
Before setting the battery charge voltage, detach the battery clamp.
You can measure the battery charge across the soldering points "+" and "-" on the base of the CPB
(CN5 Ucharge Measure).
Determine the battery charge voltage with the potentiometer P5. The battery gets charged by default with 13.6
Vdc.

Testing the FB

Fancom recommends manual testing of the audio or visual signal at least once per week.
You can test the signalling unit by setting the rotating switch to T. If the audio or visual signal activates after the
passage of any delay interval that may have been set, then the signalling unit is functioning correctly. Does the
audio or visual signal not activate? Then have your installer measure the battery voltage under load conditions. If
this is less than 10Vdc, then the battery is defective. If this is more than 10Vdc, then the audio or visual signal is
defective or not turned on properly.
0 or T, then the signalling unit is turned off. Here, it's possible to connect an external
