Case WX145 Operator's Manual page 289

SECTION 5
PROBLEM
The right lamp (3) blinks.
Different lubricant quantity on
lubrication points.
Excess or lack of lubrication on
the lubrication point.
System locking downhill.
5-20
POSSIBLE CAUSE
One of the two selectors (1) and (2) is
positioned to 0.
Signals: 4-times flickering.
Short-circuit on button (4).
Signals: 3-times flickering.
Wrong quantity.
The relevant valve body has been
assembled without locking ring.
Wrong setting of working and time-
out times.
Wrong setting of working and time-
out times.
Articulation points, pipes or
distribution manifold clogged.
The trouble can be determined from
following signals:
- grease output from pressure relief
valve;
- the checking plugs, installed on the
manifold pistons (if installed), do
not move.
Distribution manifold clogged.
CORRECTION
Set both selectors on position 3.
Check if the short-circuit is occurred
on the control board. Replace the
board if necessary.
Check the quantity according to
lubrication diagram.
Remove the valve and fit the locking
ring.
Check the times setting.
Check the setting of the working and
time-out time on control units, control
boards or controls.
Detect and clear the locking cause as
described hereunder:
Activate the tank pump.
On the main distribution manifold (B)
detach one by one all high pressure
hoses (G) leading to the sub-
manifolds. If, for instance, grease
comes out under pressure from
output 1 of main distribution manifold
(B), this means that the clogging has
to be searched in the lubrication
circuit of the sub-manifold (D).
Let the tank pump operate.
Detach one by one all high pressure
hoses (E) of the sub-manifold (D). If,
for instance, grease comes out under
pressure from output 3 of sub-
distribution manifold (D), this means
that the clogging has to be searched
in the piping of connector 3 or in the
articulation point connected to the
same.
By means of a manual pump clear all
clogged pipes of articulation points.
Replace the distribution manifold or
have it cleaned by the After-sales
service.
