Complementary information
You must configure one option only otherwise the device will go into an error status.
Whenever the safety relay configuration changes, the Flexi Loop monitoring is taught-in
again and the Flexi Loop series connection initialized. This results in a delay in the
safety relay start when the configuration is changed.

Activating configuration
Prerequisites
•
The Flexi Loop safe series connection is connected to the safety relay.
•
The safety relay is disconnected from the voltage supply.
Approach
You must activate the configuration after configuration is complete. After activation, the
safety relay will detect the configuration.
1.
Set the CS switch to the corresponding position to activate the configuration:
°
If the CS switch is in position 0, set the CS switch to position 1.
°
If the CS switch is in position 1, set the CS switch to position 0.
2.
Connect the safety relay to the supply voltage.
✓
If configuration is successful, the LEDs of safety relay 2 × light up one after
another, from top to bottom.
Complementary information
•
The initialization of the safety relay may take several seconds depending on the
length of the Flexi Loop series connection.
•
You only have to complete configuration once and activate the successful configu‐
ration process. If a configuration is faulty, you can fix the error without reactivating
the configuration.
•
If a configuration is already valid and becomes invalid at a later time (e.g. acciden‐
tally changing the DIP switch position), you have to fix the error and then reactivate
the configuration.
•
For module exchange, it can be helpful if the CS switch is at 1 at the end of
configuration. The DIP switch positions are then transferable to the new module
when replacing a module.
7.6
Resetting the configuration
Prerequisites
The safety relay is disconnected from the voltage supply.
Approach
1.
Set all DIP switches to position 0.
2.
Connect the safety relay to the supply voltage.
✓
The PWR LED flashes red (1 Hz).
