3.1.2.1 Line Diagnosis
During 2-pole operation, a line diagnosis is performed to detect potential external short-circuits
to L+ and L-. Time on delay is required to detect external short-circuits with an inductive or
capacitive load or a lamp load. This delay can be configured using the
Time on delay
system
parameter. In the range of 0...30 ms, the value can be set in steps of 1 ms.
i
Initial values must be set for all relevant system parameters of the line diagnosis
(
DO2[xx].2-Pole, Time on delay
).
Therefore, first set all required system parameters in the programming tool, then compile the
user program, and finally, transfer the program to the controller.
The settings for the system parameters configured for line diagnosis cannot be changed during
operation!
An external open-circuit will not be detected.

Figure 4: Connection of Actuators to Outputs
The redundant connection of two outputs must be decoupled with diodes. Only 1-pole switching
outputs may be connected redundantly.
CAUTION
For connecting a load to a one-pole switching output, use the corresponding L- ground
of the respective channel group (2-pole connection) to ensure that the internal protective
circuit can function.
