10.9. Configuration of the Safety
Position of Solenoid Valves if Bus
Error
If the bus fails, the solenoid valve is switched to a programmable
safety position (factory setting: the solenoid valve is in the power-off-
state) - for details see manual, chapter „Configuration of the device".
The bus status LED „Network" on the electronic module specifies the
kind of error by color and blinking pattern - for details see manual,
chapter „Display of the Status LEDs in the event of a bus error").
