Why is the RUN LED blinking and the ERR LED off on my Stahl 9440/15?
If the RUN LED is blinking and the ERR LED is off on your Stahl Control Unit, it means the unit is in standby mode, switched on but not yet exchanging data with the master. To resolve this, activate the cyclical data exchange with the master and check the master and bus connection to the CPM.
What to do if RUN LED is lit and ERR LED is blinking on Stahl 9440/15?
