Tab.1/10: Fault LED for pneumatic interfaces Midi/Maxi, CPA or VTSA pneumatics
The fault indicated by the red fault LED is transmitted by the
pneumatic interface to the field bus node (unless parame
trized otherwise).
Status LEDs of the valve solenoid coils
The yellow status LEDs on the valve solenoid coils indicate
the status of the relevant output (see appropriate pneumatics
manual).
