Test pulse outputs T0, T1
Feedback loops Y1 and Y2 can be assigned test pulses. The PNOZ s50 has 2 test pulse
outputs, T0 and T1.
Please note the fixed allocation of test pulses to the following inputs:
} T0 pulses the feedback loop Y1
} T1 pulses the feedback loop Y2
The test pulse outputs T0/T1 are switched on (24 V) in
} "RUN" operating status.
} "I/O Fault" operating status (fault on inputs and outputs).
The test pulse outputs T0/T1 are switched off (0 V) in
} "Fault" operating status (internal fault).
The test pulses can be switched on and off via the display.
} The default setting is for test pulses to be switched on.
} Test pulses will not be active in the event of a fault (I/O Fault and Fault).
Signal and status outputs O3, O4, O5
Single-pole failsafe semiconductor outputs signal the operating status of the load and indic-
ate a fault.
Fault signal output O3
1 No fault, LED "I/O Fault" and "Fault" is off
0 Fault, LED "I/O Fault" or "Fault" is lit
Status outputs
They signal the status of the
load only after the ventilation
or application time has
elapsed.
O4
1 Load at O1+/O1- ventilated
0 Load at O1+/O1- applied
O5
1 Load at O2+/O2- ventilated
0 Load at O2+/O2- applied
