Operation
NOTICE
The safety function should be checked after initial commissioning and each
time the plant/machine is changed. The safety functions may only be
checked by qualified personnel.
INFORMATION
The safety outputs are constantly checked via test pulses. This may gener-
ate a humming noise on the connected contactors, which does not affect
the function. The test pulses also mean that, when measured with a multi-
meter, the voltage at the safety outputs is displayed to be less than it actu-
ally is.
The unit detects the set operating mode once supply voltage is applied. During this time
(initialisation phase) the "POWER" LED will flash. The unit is ready for operation when the
"POWER" LED is lit continuously.
LEDs indicate the status and errors during operation:
