Installation manual
Safety instructions:
•
For applications with frequent demand for the safety shutdown, testing should be at short
intervals, e.g. at the start of the shift, 1 x per week. However, a test should be undertaken
cyclically at least 1 x per year.
•
The test function for the outputs is undertaken for group operation and individual operation.
The signal outputs are not tested.
•
The high-side (Qx_P) and low-side (Qx_N) outputs are not allowed to be used individually for
safety tasks. Usage for safety tasks is only permissible in the combination high-side / low-side.
•
Mixed operation of the relay contacts is not allowed!
•
Mixed operation:

CORRECT:
The outputs can be loaded as follows:
Output Voltage
Relay Qx 24 VDC
Relay Qx 230 VAC
Yx 24 VDC
Qx_P 24 VDC
Qx_N GNDEXT
Qx 24 VDC
Safety instructions:
•
For safety-related applications, only external switching elements with a minimum holding
current of> 1.2mA may be used.
•
For safety-related applications, only external switching elements may be used in conjunction
with the combination of p- / n-switching outputs
o with a load resistance ≥ 100 Ω with a minimum holding current of> 2mA or
o with load resistance <100 Ω with a holding power> 0.4 mW
be used.
Note:
If the auxiliary outputs are used for control purposes, it must be ensured that after a POR of the
control, the auxiliary outputs are in an undefined state in the start-up phase.
