IMPORTANT!
• Turn off the compressed air
supply with the service valve
before doing any work on the
cleaning system.
• Do not pressurise the system
if the air temperature is below
the minimum operating tem-
°
perature (= -20 C). At lower air
temperatures the process can
be started and operated for a
while (approx. 15 min.) where-
after the system can be
pressurised.
Correct the error indicated by the
function LED's, see page 21 - 22.
Check that the wiring is correct.
Closing 1 + 9 or 10 shall start
the filter.
There is an electrical fault in one
or more of the pilot valves. The
number/s shown after Err are the
number of the faulty valve/s.
Depressurise the system. Check
that the leads to the valve coil are
properly connected. Remove the
leads and measure the resistance
of the coil, it shall be approxi-
mately 26 Ω . If the resistance is
more than 29 Ω or less than 23 Ω
or if the coil circuit is cut, replace
the pilot valve.
