Tilt sensor
Remark: perform this test on the ground using the lifting platform controller. Do not
remain in the lifting platform.
• Lower the lifting platform completely.
• Set a 5 x 10cm wooden chick or a similar item in front of both wheels on the same side
and raise the machine onto them.
• Raise the basket approx. 2.1m above the ground.
> Result: the lifting platform should stop rising and the tilt alarm should sound at
180 beeps per minute. The lifting platform’s LED control screen should show “LL”
and the liquid crystal control screen at ground level should show “LL: Machine
Tilted” (Fig. A2-2).
• Press the drive function button.
• Move the translation control lever in the direction indicated by the white arrow and then
in the direction indicated by the black arrow.
> Result: the translation function should not be activated in any direction.
• Lower the lifting platform and remove the two wooden chocks.
Restricted translation speed
• Press the high speed or slow speed lifting confirmation button.
• Hold down the function confirmation switch.
• Raise the lifting platform to approx. 1.2m above the ground
> Result: the anti-pothole protection systems should deploy.
• Press the drive function button.
• Slowly move the control lever to the maximum translation position.
> Result: the maximum translation speed that can be achieved with the lifting platform raised should not exceed 22 cm/s.
• If the translation speed is more than 22 cm/s when the lifting platform is raised, place a sign immediately on the machine and put
it out of service.
Pothole protection
Remark: the pothole protections must deploy automatically when the lifting platform
is raised. These activate another limit switch that enables the machine to continue to
function. If the pothole protections do not deploy, an alarm sounds and the machine
does not operate any more.
• Raise the lifting platform.
> Result: when the lifting platform is approx. 1.2 m from the ground, the pothole
protections must deploy.
• Press on the protections from one side and then the other.
> Result: the protections must not move.
• Lower the lifting platform.
> Result: the protections must fold back.
• Place a 5 x 10 cm wooden wedge or a similar object under a pothole protection. Raise the
lifting platform.
> Result: the light should flash, an alarm should sound and the translation function
should be deactivated before the lifting platform is 2.1m from the ground.
The control screen in the basket should show “PHS” and the control screen at ground level should show “PHS: Pothole Guard
Stuck” (the protective device against potholes is jammed) (Fig. A2-3).
• Lower the lifting platform and remove the wooden wedge.
