7.4.2 Fault Location and Correction
NOTE
Error message No. 43 can indicate a fault in the flap opener.
Start fault location by referring to the section 7.2 "Fault Characteristics".
Information on the structure and functioning of the flap opener will be found in the section 7.1 "Overview".
If an individual flap opener is not being activated, the plunger will no longer extend or retract far enough or the
flap openers of an entire location (1 or 3) will not operate, proceed as described below.

Remove the cover plate over the compressed air unit from the machine base (2 special socket-head cap
screws M3) and check the pressure for the flap opener on the lefthand pressure gauge of the compressed
air unit: it must show 2.8 bar.
–
If it does not, correct the pressure at the corresponding setting knob of the compressed air unit (for
setting, see User’s Manual, Section 9).
–
If the pressure was set correctly, proceed as follows:
DANGER
QQQ
Switch off the machine at the main switch and disconnect it from the power supply.
●
Open the protective cover.
●
Tighten up the threaded hose connections at the flap opener (see Fig. 7.4.1) and at the com-
pressed air unit. Make sure that the compressed air hose is not pinched or damaged.
●
If the compressed air hose has to be replaced,
switch off the machine at the main switch and
disconnect it from the power supply.
●
Switch off the compressed air at the shut-off valve of the compressed air unit (see User’s Manual,
Section 9) and replace the compressed air hose. Replace all cable lacings in their previous posi-
tion. Fit the cover plate back over the compressed air unit.
●
Please note: The compressed air hose at the flap opener connection must be routed between the
machine base and the clamping lever in order to keep it clear of the cutter wheel.
●
Make sure the plug connection X38 at the "Flap opener control" board is firmly seated and con-
tacting properly (position: on the left below the strip, see Fig. 7.4.2).
●
Continue work with the next section.

None of the flap openers of a location is being activated: there is a fault in the 2.8 bar compressed air
branch (see Section above), or a defect in the "Flap opener control" board (see Fig. 7.4.2), or in the
cables between the flap openers interface and the communications unit.
