Fault No.10
Fault
Probable cause
Poor connection
between SI unit and
valve manifold
Any valves not
work and all
valve LEDs
Mismatch polarity
also stay off
between solenoid valve
and SI unit output
Defective solenoid
valve
Fault No.11
Fault
Probable cause
Valves not
Mismatch polarity
work but valve
between solenoid valve
LEDs can turn
and SI unit output
on
Recommended error handling
Check if there is any loosing screws for making
the connection between the SI unit and the
valve manifold.
Check if the solenoid valve common
specification match the output polarity of the SI
unit.
Follow the troubleshooting for the solenoid
valve.
Recommended error handling
Check if the solenoid valve common
specification match the output polarity of the SI
unit.
‑32‑
Recommended action
Tighten the screws with the
specified tightening torque
(i.e. 0.6 Nm) and make sure
there is no gap between the
SI unit and the valve
manifold.
Match polarity between
solenoid valve and SI unit
output
Same as left.
Recommended action
Match polarity between
solenoid valve and SI unit
output.
