Parameter "USPAN"
The adjustment of the extensiometric sensor may
move following important vibrations or repeated shocks
on the structure : the sensor's zero drifts. The alarm
is actuated when the shift reaches 20% of the signal
value (in microprocessor units) when loaded. The
threshhold for alarm activation in case the sensor's
adjustement shifts is determined by the "USPAN"
parameter. the green led [D19] flashes when the signal
value is below the value determined by the "USPAN"
parameter: refer to § Error codes. Actuation of the
alarm when the machine is lowered and the work
platform empty is a revealing sign the sensor's
adjustment has moved.
O
:
sensor's zero determined during adjustment
phase 6.
C
O
: load corresponding to the alarm activation
during adjustment phase 11.
S
:
value of the sensor's signal (in microprocessor
units) corresponding to the activation of the
alarm.
C'
:
load corresponding to the alarm activation in
case the zero shifts.
O
' :
Shift limit determined by the "USPAN"
parameter.
Should the sensor shift, it is possible to recalibrate
the system automatically and to restore the initial
work window by determinating a new zero for the
sensor: refer to the autocalibration procedure below.

Autocalibration
NOTE
Autocalibraion is always possible except with
a faulty sensor (indicated by the green led
[D19] flashing : refer to § error codes).
1. Read this procedure completely before applying
it.
2. Position the machine on flat and horizontal
ground. The machine must be lowered,
telescope retracted, superstructure in line, work
platform empty.
3. Switch the machine off and install the jumper
J14.
4. Switch the machine on again.
5. Autocalibration : Depress the SW2 button.
ç
the red led [D20] is more luminous when
the SW2 button is depressed.
The platform must be in the position
described in step 2.
6. Switch the machine off before removing jumper
J14 (stick jumper J14 inside the box with an
adhesive).
7. It is recommended to check the good working
order of the system. To do so, follow steps 15
to 16 of the adjustment procedure described in
paragraph "Adjustment of the threshhold for
setting off".
