8. FAULT IDENTIFICATION
The Series D valve island has an OPEN COLLECTOR diagnostic output with which it signals the faults that may
occur to the single valve / sub-base. The maximum controllable current is 50mA and is equipped with short
circuit protection.
(Pin 23 of the 25-pin D-sub connector and Pin 39 of the 44-pin D-sub connector)
- Non energized solenoid.
- Solenoid interrupted.
- Solenoid with anomalous current absorption or with excessive temperature.
The status of this output depends on the type of alarm set:
Blocker (Default): the status of the diagnostic output is restored by removing the fault by turning the island off
and on again.
Non-blocking: the status of the diagnostic output is restored by removing the fault or by driving OFF the
solenoid that caused the problem
The sub-bases indicate the type of alarm by means of a coded flashing of the LED associated with the individual
solenoid pilot (see following table).
