7.2.2 Acceptance of pending sensor signals (S1 and S2), for both channel 1 (Sx1) and channel 2 (Sx2)
• For the OSSDs to release, both sensors (S1 and S2) must have satisfied the conditions shown
above.
• The time offset between the sensors (S1 and S2) is arbitrary.
7.2.3 Acceptance of the RES manual release signal via the start button at (RES-I)
• At time t
1
, all four channels (Sx1, Sx2) must have satisfied the release condition (see chapter 7.2.2
„Acceptance of pending sensor signals (S1 and S2), for both channel 1 (Sx1) and channel 2 (Sx2)“).
• Release signal RES must be applied for at least

150 ms.
7.3 Circuit diagram examples
The following examples show possible connection combinations for AOPDs (relay, transistor), safety
switches and E-Stop command devices on the safety relay
The following circuit shows the connection of two AOPDs with integrated muting function in a double-
muting application, whereby the muting sensors are locally coupled to the AOPDs to reduce wiring.

All available safety inputs must be occupied! Bridges are to connect the remaining sensor inputs
where no components are connected (see table 7.2).
