Changing Switch Panel; Checking Switch Panel Indicator Lights - Valtra 6000 Workshop Manual

32. Electro---hydraulic power lift
C. Changing switch panel
N.B: If the voltage measurements show that the switch panel
is defective the panel must be replaced as a complete unit as
follows:
1. Detach the switch panel from the bracket by removing se-
lector knobs and by unscrewing ring nuts.
2. Remove also the lock washers and dust seals. Detach the
switch panel connector so that the panel can be removed.
.
3. Fit onto new selectors washers with lugs. These washers
limit selector positions. Before fitting the washers turn every
selector anti ---clockwise as far as possible to their extreme
position. After this has been done, fit the washers so that the
lugs engage in the holes at number six on every switch (see
figure above). Make sure by turning the switches that they
have six different positions.
4. Connect the connector to the new panel. Fit the dust covers
(317 204 20). Fasten the circuit card to the panel by means of
ring nuts (fit under nuts lock washers JE 9423).
5. Attach the connector to the switch panel. Fit the switch
panel onto the bracket by means of the ring nuts (fit the cup
washers under the nuts).
6. Fit the selector knobs and place the bracket onto the lever
console with four cross head screws.
D. Checking switch panel indicator lights
If Autocontrol power lift functions properly, but indicator lights
on the switch panel do not function correctly the following
steps must be taken:
--- Detach the switch panel (instr. A) and move the connector
on the panel so that possible poor contacts disappear.
--- If an indicator light is still out of order the voltage measure-
ments shown in instruction B must be carried out.
--- If voltages are between allowable limits but light is still out of
order the fault is in the bulb and the whole switch panel has to
be changed as a complete unit (see instruction C)
