5.1.4.6.4
Drive enable green warning light (R)
This light is ON when drive can be carried out.
Drive movement is inhibited
(
green light OFF
) when:
a)
One or more levelling cylinders are not completely retracted (did not reach the upper stop). See also warning lights
ZB
– only machines with levelling cylinders;
b)
Platform is above the maximum drive height (see paragraph “Technical features”);
c)
Sliding platform is “out of center”. See also green warning light
P
– only machines with sliding platform;
d)
With lifted platform the machine is on a ground inclined over the max. allowed inclination. See warning lights
S
and
T
;
e)
With lifted platform, the platform is overloaded. See warning lights
U
and
T
.
5.1.4.6.5
Danger red warning light (S)
It flashes quickly for 4 seconds together with the acoustic alarm at the machine start-up in case of fault during safety test on
controls (pedal, joystick control, switches, etc) during machine start-up.
It is lit up steady together with the acoustic alarm when the chassis inclination exceeds the allowed value. Lifting and platform
extractions are inhibited (in case of electric control). If platform is lifted, drive is also inhibited. It is necessary to lower the
platform completely and then place the machine onto a flat surface.
CAUTION!
The activation of this indicator warns of a dangerous situation since the machine has reached a
dangerous inclination level for the machine stability.
5.1.4.6.6
Lifting enable green warning light (T)
This light is ON when lifting can be carried out, i.e. when:
a)
All or none of the pads are resting on the ground (no pads resting means that the machine rests on its wheels). See
also warning lights
ZB
– only machines with levelling jacks;
b)
Sliding platform is in retracted position. See also warning light
R
– only machines with sliding platform;
c)
Machine is in levelled position. See also warning light
S
;
d)
Overload alarm is not present. See also warning light
U
;
e)
Flat battery alarm is not present. See also warning light
Q
– only models “E” and “E/D”.
5.1.4.6.7
Overload red warning light (U)
On steady and activation of acoustic alarm with a platform overload exceeding 25% the rated load. If the platform is lifted, the
machine is completely locked. If platform is completely lowered all driving/steering operations are still possible but lifting is
inhibited. Remove the overload before using the machine again.
Fast flashing in case of fault in the control system of the platform load. With lifted platform the machine is completely blocked.
After reading the manual instructions, trained staff can carry out an emergency manoeuvre for platform recovery (Chapter
“Maintenance”).
CAUTION!
The activation of this indicator is a synonym of danger since the load at platform is exceeding or no
load control is active upon signalling.
For adjustment or activation in emergency situations read the MAINTENANCE chapter.
