Safety systems
Microswitches
Some microswitches are positioned on the machine with safety fun-
ctions.
SQ1 Microswitch
•Enables the atness indicator which locks the machine movements
if this last exceeds the maximum slope, except for the lowering op-
eration.
•Inserts the drive reduced speed.
• Prevents traction and steering movements in case the protections
against overturning are not lowered (combined with SQ6A-SQ6B
microswitches).
IT10122 - IT12122
The SQ1 microswitch has enabled through the platform liing move-
ment
SQ5 Microswitch
The SQ5 microswitch, placed on the le back part of the base truck
has enabled through the platform liing movement to a height of 2.25
m (IT10122) - 2.45 m (IT12122) from the oor surface.
• Prevent traction and steering movements in case the protections
against overturning are not lowered (combined with SQ6A-SQ6B
microswitches).
SQ1 is formed by a proximity sensor system and it is composed of:
- A rectangular-shaped magnetic unit
- A rectangular-shaped sensor with contacts.
SQ1 condition not activated
With the platform rest the sensor and the magnetic unit are near.
SQ1 condition activated
With platform lied when the sensor and the magnetic unit are sepa-
rated for more than 3 cm.
