7.10 LED Test
An LED test is provided (as from PCB version 11) for the MDO which enables a visual functional
test of the front panel LEDs. This test can be carried out independently from the active operating
state of the SUPREMA and does not affect the mode of operation of the SUPREMA. To carry
out the LED test, please press the switch shown in the illustration. The front panel LEDs should
now be illuminated (System – power, fail, inhibit and Signal – 1
st
to 4
th
alarm, fail). If there is an
LED that is not illuminated when the switch is pressed, it is possible that the MDO module
needs to be replaced.
