The Control Station does not op-
erate when the main switch is
switched on!
- See ”
6.1.1 Electric fault” on page 89
.
The bout marker(s) cannot be
unfolded!
- Check according to ”
6.1.1 Electric fault” on page 89.
- Check according to ”
6.1.2 Hydraulic fault” on page
89.
- Check whether one of the bout marker indicator lamps
on the Control Station lights.
- Check whether the machine is in the low-lift mode.
(For safety reasons the bout markers cannot be un-
folded in the low-lift mode or at a higher height.)
- Check the low-lift switch. Disconnect the switch con-
nector from the Workstation and verify correct bout
marker operation.
- Check the wing unfolding switch. This switch blocks
the current signal from the bout marker valves when
the wings of the drill are retracted. This prevents a
bout marker from being unintentionally unfolded in
this position. Disconnect to the switch connector from
the Workstation and verify correct bout marker oper-
ation.
- Check the current supply to the two electric valves (A)
and (B) in the centre of the top surface of the valve
block. See ”
6.1.3 Hydraulic electric valves” on page
90.
The bout marker valve(s) should receive current
when the corresponding indicator lamp lights.
The bout marker(s) cannot be
retracted!
- This is probably caused by contamination in an elec-
tric valve. Please note that contamination that causes
faults such as this often is not visible to the naked eye.
In this case, replacement of the electric valve is rec-
ommended.
- It should always be possible to retract both bout mark-
ers no matter which setting and indication are ob-
served on the Control Station and also when the
Control Station has been switched off.
