Single-channel operation: no re-
dundancy in the input circuit, earth
faults in the reset and input circuit
are detected.
Dual-channel operation without de-
tection of shorts across contacts:
redundant input circuit, detects
– earth faults in the reset and input
– short circuits in the input circuit
Dual-channel operation with detec-
tion of shorts across contacts: re-
dundant input circuit, detects
– earth faults in the reset and input
Power: Supply voltage
Reset/start: Reset circuit S34 S34
Input: Input circuits S11-S12, S21-
S22
Output safe: Safety contacts 13-14,
23-24, 33-34
Output aux: Auxiliary contacts 41-
42
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24, 33-34 are
safety contacts, output 41-42 is an
auxiliary contact (e.g. for display).
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical de-
tails).

Automatic start: Unit is active once
the input circuit has been closed.
Manual reset: Unit is active once
the input circuit is closed and then
the reset circuit is closed.
Monitored reset with falling edge:
Unit is active once

Use copper wire that can withstand
60/75 °C.
Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.

Monitored reset with rising edge:
Unit is active once the input circuit
is closed and once the reset circuit
is closed after the waiting period
has elapsed (see technical details).
Reset with start-up test: The unit
checks whether safety gates that
are closed are opened and then
closed again when supply voltage
is applied.
