12.1 PROBLEMS SOLUTIONS
DEFECT POSSIBLE CAUSE SOLUTION
Display OFF Fuse burnt.
Supply voltage.
Jumper for input voltage selection Check the protection fuse on supply line.
Check if supply voltage is present and if it
agrees with supply voltage needed by the
device (clamps 1 and 2).
Check jumper JP1.
No output activation Output voltage.
Connection to the electrovalves.
Jumper for output voltage selection Check that sequencer output voltage and
electrovalve coils have the same voltage.
Check the connection between sequencer
and electrovalves and do manual test of
the outputs (See B10 / B10b).
Check jumper JP2 and JP3.
The cleaning cycle do not run in according
to the set value. The memory of the microprocessor could
be modified by external factor. Switch Off the supply voltage of the
sequencer. Hold down key A and switch
on the supply voltage. By means of this
operation the default data are loaded in set
up. Adjust the zero dP reading and the
other parameters according to the filter's
needs.
