Festo FB13 - 5.7 Error Treatment; Reaction to Faults in the Control System

5.7 ERROR TREATMENT
Reaction to faults in the control system
The reaction of the Festo valve terminals types
03-05 depends, in the case of the following
faults, on the configured reaction of the master
module.
• telegram failure
• master stopped
• interruption in bus cable
Depending on the setting or the configuration, all
the outputs (valves and electrical outputs) are
switched off or maintain their status.
WARNING
Ensure that the valves and outputs are reset
after the faults name. A dangerous situation
can arise, if the valves and outputs are not
reset.
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.
