4.8.2. Speed control module for the jib
(build-in electronic plug)
F
UNCTION
: Reduction of the speed for the jib Elevation
/ lowering movements when reaching the end of its
higher travel.
Jib higher position switch [SW3]
: see § 4.2.4.

OCATION
: The module is connected to the plug [CR15]
on the electronic card of the platform control panel.
Operating principle
The speed reduction is obtained by placing a 1,2 k
Ù
resistance between the 0 V and the cursor of the
potentiometer for structure movements :
The speed reduction depends from the position of the
structure movement potentiometer :
- No speed reduction if the potentionmeter is on
minimum.
- Reduction of the maximum speed if the
potentiometer is on maximum.
During a jib lowering movement from its higher
position, the release of the switch [SW3] restore the
movement normal speed.
