Siemens Wiring Schematic Safe Output with Sensor Test Pulse to Interface to
Safety Exhaust Valve
With this schematic it is possible to achieve up to category 4 PL e if properly implemented.
External monitoring program for Siemens Simatic S7*
a) If Dia.0 = Dib.0 = 1 AND safety hardwire circuit in Active state AND no faults present THEN SET O0 = 1 when
commanded
b) Sensor discrepancy error: Dia.0 <> Dib.0 (max. discrepancy time = 150 msec)
c) Loss of pressure error: O0 = 1 AND Dia.0 = Dib.0 = 0
followed by Dia.0 OR Dib.0 AND O0 = 1
d) System pressure error: O0 = 1 AND Dia.0 = Dib.0 = 1 for x amount of time (where x is system pressurization
time dependent on volume) Default 3 secs.
e) IF sensor discrepancy error OR loss of pressure error OR system pressure error THEN reset O0 = 0
Errors must be reset only after maintenance acknowledgement
