Calibration procedure:
1
- Retract the boom all the way, bringing it in a
horizontal position.
- Lower the boom with an abrupt movement of the
control lever, in order to “bounce” the machine;
return the boom to the horizontal position and wait
for oscillations to dampen out.
- Rotate trimmer
VR1
(see Fig.15) until LED2 turns
off (rotating the trimmer clockwise turns off more
LEDs, and viceversa); after LED2 turns off, rotate
the trimmer clockwise two and half turns more.
4
- Load the forks with the known weight.
5
- Extend the boom to the distance previously found
on the load chart. If LED5 turns on while the boom
is being extended (and therefore the boom locks
out), turn trimmer
VR
clockwise approximately five
turns.
6
- Lower the boom with an abrupt movement of the
control lever, in order to “bounce” the machine;
return the boom to a horizontal position and wait
for oscillations to dampen out.
7
- Rotate trimmer
VR
counterclockwise until LED5
is lit; at this point, rotate
VR
counterclockwise
another half turn.

After completing the calibration procedure, make sure the
alarm is activated at the required distance. Then replace
the main module on its support.
If, during the calibration procedure, the LEDs light
up in an unusual manner (for example, LEDs 2 and
3 off, LEDs 4 and 5 on) proceed as follows:
•
turn trimmer VR1 counter-clockwise approximately
ten turns.
•
turn trimmer VR2 clockwise approximately ten
turns.
