6.3 SEQUENCE OF SETTINGS FOR LIFTING
- With the machine switched off, connect the programming console and then switch
on. If no wiring errors or component defects are found, the display shows the manu-
facturer’s name, programme release, configuration, and hour-metre value.
If the module has already been configured, the procedure passes directly to step
four. Otherwise, proceed in order as follows.
Consult the console manual for further procedure details.
1) Configure the chopper model.
2) Select the desired options.
3) Select and set battery voltage.
4) Check the functioning of all the wired inputs, including the potentiometer, by means
of the tester functions on the console.
5) Carry out accelerator signal acquisition on the “PROGRAM VACC” menu.
6) Set the maximum current by selecting the level corresponding to the desired value.
7) Set the speed of the respective functions with the machine in standby, and the level
of compensation set at “0”. Then apply a load and set the compensation until it
reaches the desired speed.
As the adjustments of speed and compensation are interdependent, further adjust-
ments must be made before reaching the optimum condition.
8) Set the hydrodrive speed in the same way as the others, with the only difference
being that the speed is set with the steering in standby, while the compensation is
set with the steering under load.
9) Set acceleration, deceleration, and creep as necessary.
6.4 SETTING THE PROPORTIONAL SOLENOID VALVE
- For handling the solenoid valve, it is necessary to fit the potentiometer and the de-
scent request microswitch.
1) Carry out the potentiometer signal acquisition using the “PROGRAM VACC” func-
tion.
2) With the lever in minimum speed position, set the “MIN VALUE VOLT” parameter
by incrementing the level until it begins to descend.
3) With the lever in maximum speed position, set the “MAX VALUE VOLT” parameter
by decreasing the level until you notice that the descent speed begins to reduce.
4) Acceleration and deceleration are set by obtaining the right compromise between
response speed and smoothness of movement.
