• The Short circuit test parameter is only accepted by the F I/O module with
the "active" value.
• All inputs are sensitive to clock output T1 and are tested for short circuit on
any 24 V signal source.
• Clock output T2 is switched off.
• The signal states on the digital inputs are not analyzed in advance by the
F I/O module. A separate function block is required.

Parameter Open Load Detection

The Open load detection parameter is used to separately activate or deactivate
open load detection for each individual power output.
Open load detection is only possible on digital output Ox. Therefore, we
recommend that you wire the load to be switched between the Ox+ and Ox-
connections.
If you have set the Open load detection parameter to "active", the supply lines
from the digital power outputs to the loads to be switched are monitored for open
loads.
If you have set the Open load detection parameter to "not active", then the
supply lines are not monitored for open loads by the F I/O module.
Open load diagnostics are performed just once per minute!
Open load monitoring is performed once per minute.
Open load detection is not safety related and cannot be part of the safety
function under any circumstances.
Open load detection is only possible if the test pulse length is set to >
0 ms!
Open load detection is only possible if the test pulse of the digital power output
affected is set to > 0 ms.
Open load detection is not safety related and cannot be part of the safety
function under any circumstances.
