•
S1 and S3 must always be connected.
•
S2 must be connected depending on the program.
All later changes at the connection of S1, S2 and S3 cause a lock-out (ERR).
•
During the configuration phase (when the voltage is activated) of the manual reset with
the reset button, the corresponding S-input must be open or be connected to a high-
resistance output, for example of a PLC (high or low potential causes an incorrect
configuration).
•
In order to monitor external contactors that may be connected to the safe outputs Q1 to
Q4, the N/C contacts of the respective contactors or output extensions have to be con-
nected in series with the corresponding control inputs.
