9.5 Configuration and setting the delay time (undelayed and delayed)
Note
The configuration can only be modified after disconnecting the power supply.
Changes during operation are not accepted. The device is in the configuration mode if you
configure it under voltage and then deactivate and reactivate the power supply. The device is
therefore in the safe state and all enabling circuits are deactivated.
Note
Adjusting the potentiometer for the delay time leads to no immediate device action in
protection mode.
The "DEVICE" LED signals "Potentiometer setting changed" (changes from green to
green/yellow flashing). The delay time is not, however, changed.
After the device is restarted (using RESET or by disconnecting and reconnecting the power
supply), the device is in configuration mode for the delay time. The device is therefore in the
safe state and all enabling circuits are deactivated.
