FAULTS AND REMEDY

he following pages contain an overview of

faults which may occur on the CARD G FIT with appropriate troubleshooting.

NOTE:

The numbers mentioned between parentheses in this chapter are references to
part numbers in the schematic drawing in chapter 6 on page 9, and the
numbers mentioned between brackets are references to the wiring diagram at
the end of this manual.

18.1

AULTS WITH

ISPLAY

EXT

The pressure switch (1.3) [2S5] in the process air circuit reports no or low air pressure.



No or low compressed air at the inlet of the
CARD G FIT unit (1.1).



Check if compressed air supply matches the
requirements (see chapter 7 on page 11).



Leaks in the compressed air line inside the
CARD G FIT unit.



Check for leaks and seal any leaking fitting.



Compressed air alarm is only detected when
the hopper loader is running.



External compressed air lines are too small
or the external air pressure is too low (see

the requirements in chapter 9.1 on page 15).



The compressed air inlet of the CARD G FIT unit
is blocked.



Check compressed air supply and the inlet of
the compressed air in the CARD G FIT unit.



The compressed air switch (1.3) [2S5] is not
correctly set.



Use the adjusting screw on the pressure
switch to adjust the alarm set point to 3.0bars

[40PSI].



The pressure regulator (1.4) is not correctly set.



Contact

or its exclusive

representative for the correct setting.



The compressed air pressure switch (1.3) [2S5]
is defective.



24V DC must be measurable at both terminals
(to ground) of the switch when compressed

air is available. Replace the switch if needed.



Solenoid valve (1.2) [3Y14] does not open when
drying is activated.



Check voltage supply 24VDC to valve; if OK,
replace valve.
