With the following faults, the reaction of the CP system de-
pends on the configured reaction of the master module.
– Telegram failure
– Master has stopped
– Interruption in bus cable
When the setting or configuration is completed, all the out-
puts (valves and electric outputs) will be switched off or
maintain their status.
Warning
S Make sure that valves and outputs are reset when the
faults mentioned occur.
A dangerous situation can arise if the valves and outputs
are not reset.
Please note
Unilaterally actuated valves move to the basic position.
Double-solenoid valves remain in the current position. If
mid-position functions are implemented with CP valves,
these move to defined positions (pressurized, exhausted,
blocked).
