UNCTIONS
:
- Management of start sequences :
When the joystick is actuated for a drive movement
(speed selector on (
)), the work platform starts at
( ) speed and switches automatically to
( )speed. The delay to switch to ( ) speed can
be adjusted using the potentiometer (P1).
- Management of progressive start / stop
sequences :
When the joystick is actuated slowly
for a drive movement (speed selector on ( )), the
platform starts at ( ) speed and should switch to
( ) speed only when the value of the acceleration
signal (of the joystick potentiometer) has reached
approximately 70%. The automatic switch from (
)
speed to ( ) speed, during a slow reduction of the
acceleration signal, is done for a signal value of 40%.
The speed change threshold can be adjusted using
the potentiometer (P2).
- Management of stop sequences and sudden
reversal of the drive direction
:
In the event of sudden reversal of the drive direction,
the platform slows down then stops before restarting
in the opposite direction (as described in the start
sequence). The delay for the platform to restart in the
opposite direction can be adjusted using the
potentiometer (P3). During this delay, the hydraulic
power unit turns at low speed, supplying the make up
flow to the wheel motors.
- Automatic switch to ( ) speed during the use
of differential locking.
When the differential lock is actuated, input [E12] of
the module is supplied and causes the deactivation
of output [E11] (power cut to the coil [HI-LO] - switch
to 2nd drive speed (
)).
- Management of the drive movement cut out -
see § 4.3.
- When the circuit linking Inputs / Outputs [E5]
and [E7] is cut - see § 4.3 :
ç
Output [E6] is actuated : supply to the "Pump
Inhibit" function of the controller - see §
4.5.
ç
The output [E19] is desactivated : the supply
is cut to
of the coil [DV1].
- Management of the combination of lowering
movements
:
The combination of the mast lowering and jib
lowering movements is prohibited for platform height
over 5m (switch on mast 2 actuated) : the first
controlled lowering movement (input E25 : jib, E26 :
mast) is performed (input E27 : jib, E28 : mast).
In case the mast lowering and jib lowering movements
are controlled simultaneously (possible from the
emergency control panel), the mast lowering
movement has priority.
Simultaneous mast and jib lowering movements are
authorized for platform height les than 5m.
