You can also connect two contactors parallel to one digital power output and
connect the normally open contacts of the contactor in series to the more to be
connected.
If you want to deactivate open load detection for the contactors, set the Open
load detection parameter to "not active". Otherwise, set the Open load
detection parameter to "active" so that the F I/O module performs the open load
detection task once per minute.
For more information about configuring the F I/O module, read section
"Parameterization of the F I/O module with the WAGO Parameterization Tool".
Please note that open load detection may not be part of the safety function under
any circumstances.
With this connection, you can achieve SIL3/Cat. 4/PL e by re-reading the relay
states.
Open load detection on the digital outputs
To monitor line interruptions between the digital power outputs Ox+ or Ox− and
the connected load, you can set the line break detection parameter for each
digital power output separately.
Open load detection is not safety related and cannot be part of the safety
function under any circumstances.
