Reaction to faults in the control system
The reaction of the Festo valve terminal/valve
sensor terminal type 02 depends, in the case of
the following faults, on the configured reaction of
the master module.
•
telegram failure
•
master stopped
•
interruption in bus cable
When the setting or the configuration has been
completed, all the outputs (valves and electrical
outputs) are switched off or maintain their status.
WARNING
Ensure that the valves and outputs are reset
after rectifying the faults named. In this way
you can avoid dangerous situations
PLEASE NOTE
Single solenoid valves move into the basic
position; double solenoid valves remain in the
current position; mid-position valves move to
the mid-position and (depending on the type)
are pressurized, exhausted or blocked.
