Safety note:
• For applications with frequent safety shut-down requests these tests should be performed
more frequently, e.g. at the beginning of the shift, 1 x per week. However, a test should at
least be carried out cyclically 1 x year.
The test function for the outputs is performed for groupes and individual controls. The auxiliary
outputs are not tested
• The High-Side (Qx_PP) and Low-Side (Qx_PN) outputs must individually not be
used for safety duties. Any use for safety duties is only permitted for High-Side /
Low-Side combination
(Note: not relevant from FW release 05-00-00-01)
• A mixed operation with the relay contacts is not permitted!
Mixed operation: A dangerous contact voltage potential may not be mixed with a
protective low voltage.
Example:
FALSE: 230 VAC (120 VAC cULus) are switched over Q1.1 + Q1.2 and 24V
DC are switched over Q2.1+Q2.2.
TRUE: 230 VAC (120 VAC cULus) are switched over Q1.1 + Q1.2 and over
Q2.1 + Q2.2 respectively.
Or 24 VDC are respectively switched over Q1.1 + Q1.2 and Q2.1 +
Q2.2.
The outputs can be loaded as follows:

Safety note:
• For safety relevant applications only external switching elements with a minimum
withstand current of > 1.2 mA may be used.
• For safety-technical applications, only external switching elements may be used in
connection with the combination p-/n-switching outputs
o at a load resistance ≥ 100 Ω with a minimum holding current of > 2mA
or
o at a load resistance < 100 Ω with a holding capacity > 0.4 mW
