5.1.5.2 Levelling outriggers manual control(OPTIONAL)
The machine can be supplied with an optional automatic levelling system. The system has two operating modes:
manual mode
(see previous paragraph)
automatic mode
For
AUTOMATIC LEVELLING
set the control lever
ZC
downwards.
The control system will independently control the levelling
outriggers until the machine is levelled.
Levelling is correct when:
All four warning lights ZB turn on.
Inclination alarm warning light
S
turns off (if an alarm condition due to instability was present before levelling control) and lifting enable
warning light
T
turns on at the same time and the audible alarm is activated.
For
AUTOMATIC RETRACTION
of all pads, set the control lever
ZC
upwards.
The control system will retract all pads up to the
upper end stop.
Retraction is complete when all warning lights
ZB
turn off and audible alarm is activated.
During automatic levelling, the system aims to level the machine within an allowance of 0.4° both
longitudinally and transversally. The system continues the pad control until levelling within this
tolerance is reached. If the automatic system is unable to obtain levelling within the expected
allowance, yet the four pads are firmly resting on the ground and the machine is within the stability
limits controlled by the inclinometer, the lifting enable green warning light T will still light up and lifting
can be carried out.
Excessive longitudinal and/or transversal inclinations may prevent the automatic levelling from being
reached.
5.1.6 Other functions of the platform control panel.
5.1.6.1 Selection of electric/thermic propulsion (OPTIONAL)
On a few models the drive power type can be selected using the selector
H
Set it to position
ELECTRIC
to use the electric power drive (battery
or mains power); set it to position
THERMIC
to use the thermic drive power (Diesel engine for models ED; petrol engine for models EB).
5.1.6.2 Electric pump start/stop button (OPTIONAL)
Diesel-powered models can be equipped, on request, with an electric pump (230V single-phase or 380V three-phase) as an
alternative to thermic drive power for short works indoors.
If the machine is correctly connected to the mains power (230 V or 380V depending on the available function), and selector
H
is in position
ELECTRIC
, by pressing button
I
– before operating the “dead-man” pedal
ZE
or “dead-man” button
ZD
– the pump is turned on (if off) or
turned off (if on).
The electric pump is ON when the green led close to button
I
is lighting up.
In the event of a 380V three-phase electric pump, the machine controls are enabled only after 3 sec. after pump starting.
WARNING!
Always check the position of the cable during the movements.
