Operating modes

The different coils of the master reset have different
operating modes
• Z1: For Q outputs: controls outputs Q1 to Q8 and S1 to S8.
• Z2: For markers M, N: controls the marker range M1 to
M16 and N1 to N16.
• Z3: for outputs and markers: controls Q1 to Q8, S1 to S8,
M1 to M16 and N1 to N16.
Function of the master reset function relay
A rising edge or the 1 signal on the coil will reset the outputs
or markers to 0, depending on the operating mode set. The
location of the coil in the circuit diagram is of no importance.
The master reset always has the highest priority.
The contacts Z1 to Z3 follow the status of their own coil.
Example: Resetting outputs
All outputs that you have used can be reset to 0 with one
command.
A rising edge at the coil of Z1 will cause all Q and S outputs
to be reset.
Example: Resetting markers
All markers that you have used can be reset to 0 with one
command.
A rising edge at the coil of Z2 will cause all markers M and
N to be reset.
