At the BEKOMAT
32U, two LEDs indicate the individ-
ual operating states.
When applying supply voltage, the BEKOMAT
carries out a self-test.
Both LEDs are lit for approximately 1 second, subse-
quently, the device changes over to the "ready-to-op-
erate" state.
Ready to operate, voltage is applied.
In the event that the condensate discharge is dis-
turbed, an alarm mode will start which is indicated by
the flashing of the red alarm LED.
