Principle wiring for NCNC or NCNO control
When using the NCNC or NCNO control, the safety switches are supplied by the clock signal (S21,
S11). Safety input 1 (S12) is connected with S11 via the switch. Safety input 2 (S22) is connected
with S21 via the switch. Cross-circuits on the safety inputs are monitored by the AS3-SV safety
valve in this control. Start (pressurization) takes place using the start input X2 in this control.

Principle wiring for PM control
Input M of the AS3-SV safety valve must be connected with the safe negative output D0-M
(e.g. safe output assembly) of a PLC. Input P of the AS3-SV safety valve must be connected with
the safe positive output D0-P (e.g. safe output assembly) of a PLC. The "automatic start" function
is used in this operating mode, therefore X2 must be connected with 24 V DC. The contacts have
the following assignment for PM control:

Take the AS3-SV safety valve into operation
Proceed as follows in order to take the AS3-SV safety valve into operation:
1. Switch on the pneumatic supply.
2. Switch on the 24 V DC supply voltage.
"Pressurization" function
If the AS3-SV safety valve should pressurize the machines, you must switch both safety inputs 1
and 2 with the right signal sequence. If the signal sequence is not correct, the AS3-SV safety
valve goes into the safe state. Exhausting of the operating line is the safe state.
"Exhaust" function
If the AS3-SV safety valve should exhaust the machines, you must switch both safety inputs 1
and 2 with the right signal sequence. The AS3-SV safety valve goes into the safe state if the
AS3-SV safety valve is isolated from the supply voltage or if a fault occurs during operation.
Exhausting of the operating line is the safe state.
Signal sequence when switching on
The following signal sequence results when switching on the AS3-SV safety valve (see
The AS3-SV safety valve is not supplied with 24 V DC before time 1. Signal output (41, 42) is open
(41, 42=0) and the RUN-LED is off (0). The AS3-SV safety valve exhausts the operating line.
The AS3-SV safety valve is supplied with 24 V DC at time 1. The RUN LED and all other LEDs flash
briefly when switched on. The device performs a self-test. This self-test takes a maximum of
1.5 s. After the self-test (4) has been successfully carried out, the AS3-SV safety valve is in the
ready state (2). The RUN-LED (1) is illuminated in the ready state and the signal output is closed
(41, 42=1). The AS3-SV safety valve is ready for control via both safety inputs.
If the device is disconnected from the supply voltage at time 4,

the signal output is open (41, 42=0).
Signal sequence for PP control
The following signal sequence results during PP control of the AS3-SV safety valve (see
The AS3-SV safety valve is in the ready state before time 1, but is not activated. In this state
(AS3-SV=0) the AS3-SV safety valve exhausts the operating line.
Signal input S22 is actuated with 24 V at time 1. If signal input S12 is also actuated with 24 V
within synchronization time (4), the AS3-SV safety valve goes into the pressurized state
(AS3-SOV=1) at time 2. OUT LED illuminates and indicates the activated state.
The synchronization time for monitoring (4) is 0.5 s. The state of signal inputs 1 and 2 is
displayed by the IN 1 LED and IN 2 LED.

WARNING
If the interval between signal inputs 1 and 2 is longer than the synchronization time for
monitoring, the AS3-SV safety valve remains in the non-activated state. In this state (AS3-SV=0)
the AS3-SV safety valve exhausts the operating line and OUT LED is not illuminated. The IN 1 LED
and IN 2 LED flash fast and indicate that signal inputs 1 and 2 have not been actuated
synchronously.
If signal input 1 and/or signal input 2 is actuated with 0 at time 3, the AS3-SV safety valve goes
into the non-activated state (AS3-SOV=0) and exhausts the operating line. OUT LED is off. Signal
inputs 1 and 2 must be on 0 to re-pressurize. The IN 1 and IN 2 LEDs are off in this state.
Signal sequence for NCNC control
The following signal sequence results during NCNC control of the AS3-SV safety valve (see

(AS3-SV=0) the AS3-SV safety valve exhausts the operating line.
Signal input S22 is connected with clock output S21 at time 1 via the switch. If signal input S12
is connected with clock output S11 via the second switch within synchronization time (6), the
AS3-SV safety valve goes into the "wait for start" state at time 2. The AS3-SV safety valve
remains in the non-activated state (AS3-SOV=0) and the exhausts the operating line. OUT LED
indicates this state by flashing slow.
The synchronization time for monitoring the signal inputs is 0.5 s. The state of signal inputs 1
and 2 is displayed by the IN 1 LED and IN 2 LED.
If the interval between signal inputs 1 and 2 is longer than the synchronization time for
monitoring, the AS3-SV safety valve remains in the non-activated state. In this state (AS3-SV=0)

and IN 2 LED flash fast and indicate that signal inputs 1 and 2 have not been actuated
synchronously.
If start signal X2 is changed from 0 V to 24 V (positive flank) at time 3 and is changed back from
24 V to 0 V (negative flank) at time 4, the AS3-SV safety goes into the pressurized state
(AS3-SV=1) at time 4. OUT LED illuminates and indicates the activated state. The time for
monitoring signal X2 is between a minimum of 0.03 s and maximum 3 s. If X2 is not actuated
within this monitoring time, the AS3-SV safety valve remains in the exhausted state (AS3-SV=0).
If the connection between S11 and S12 or between S21 and S22 is interrupted via the
corresponding switch after time 4, the AS3-SV safety valve goes into the non-activated state
(AS3-SOV=0) and exhausts the operating line at time 5. OUT LED is off. Both signal inputs 1 and
2 must be open/interrupted to re-pressurize. The IN 1 and IN 2 LEDs are off in this state.
