System Lamp Test.
The Main Unit conducts a short lamp test on start up but a lamp test of the
entire system (including Outstations) can be carried out during set up and
prior to the commencement of the event if required. With the system pow-
ered up, hold down the ‘Dimmer’ Group B, ‘Standby’ and ‘Go’ buttons all
together until all the Main Unit LEDs illuminate. Release the buttons and
the Main Unit LEDs will now flash slowly across all channels. The red
‘Short’ LED will flash also and the power LED will remain illuminated con-
stantly. This test will verify that all LEDs are functioning properly. Whilst in
this mode, all LEDs and lamps on all Outstations will flash also so each
can be checked for full functionality. To cancel lamp test mode, hold down
the ‘Dimmer’ Group B, ‘Standby’ and ‘Go’ buttons all together again or
power down the Main Unit.
Individual Outstation Lamp Test.
To lamp test any Outstation, disconnect the power input XLR cable from
the Outstation, wait 10 seconds for the Outstation to fully power down,
then reconnect the power again. The Outstation performs a short lamp test
whenever it is powered up.
Diagnostic Mode.
This mode allows the operation of the LEDs and data communications to
be verified. Enter the diagnostic mode by pressing both of the Group B
‘Standby’ and ‘Go’ buttons for approximately 4 seconds, until all LEDs on
the Main Unit illuminate. Release the buttons and the ‘Go’ and ‘Standby’
LEDs on all Outstations flash alternately. Any ‘Fault’ LEDs illuminating
briefly is an indication of data communication errors. The usual causes for
this are excessive cable lengths and/or too many Outstations at the end
of a long cable run. Exit the Diagnostic Mode by pressing either of the
Group B ‘Standby’ or ‘Go’ buttons ,or by powering down the Main Unit.
