Operation
When the relay outputs are switched on, the mechanical contact on the relay cannot be
tested automatically. Depending on the operational environment, measures to detect the
non-opening of switching elements may be required under some circumstances.
When the product is used in accordance with the European Machinery Directive, a check
must be carried out to ensure that the safety contacts on the relay outputs open correctly.
Open the safety contacts (switch off output) and start the device again, so that the internal
diagnostics can check that the safety contacts open correctly
} for SIL CL 3/PL e at least 1x per month
} for SIL CL 2/PL d at least 1x per year
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.

Status indicators
LEDs indicate the status and errors during operation:
LED on
POWER
Supply voltage is present.
CH.1
Safety contacts of channel 1 are closed.
CH.2
Safety contacts of channel 2 are closed.
Faults – Interference
} Earth fault: The supply voltage fails and the safety contacts open. Once the cause of the
respective fault has been rectified and the supply voltage is switched off for approx.
1minute, the unit is ready for operation again.
} Contact malfunctions: If the contacts have welded, reactivation will not be possible after
the input circuit has opened.
} LED "POWER" does not light: Short circuit or no supply voltage.
