6. Automatic Levelling System
The central control box is fitted with an automatic levelling system that allows the platform to
maintain a stable horizontal position. An out of level condition can occur when one of the hoists
is working faster than the other, or if the load in the platform is not evenly distributed.
When the platform is in motion, the automatic levelling system stops the hoist that is going too
fast and allows the other hoist to catch up. When both hoists are level again, the levelling
system is deactivated and both hoists will function simultaneously.
The automatic levelling system is activated when the platform is out of level by 6°.
The Automatic Levelling System can be tested by using the hoist selector switch to create and
out of level condition. Once the platform is out of level, check that the hoist that is too high no
longer works in the ’up’ direction and the hoist that is too low no longer works in ‘down’
direction.
7. Overheating protection for hoist electric motor
The hoist motors are fitted with a thermal contact, which cuts power to the motors in case of
overheating.
When the overheating protection is ac
tivated, the ‘up’ movement is halted.
If a hoist motor has overheated, allow it to cool down to continue.
The overheating protectors of both hoists are connected in series. If one overheating protector
is triggered, then the ‘up’ movement of both hoists is halted.
8. Overspeed Safety device (Mandatory for any BAP 360° platform)
The overspeed safety device locks onto the suspension rope when the suspension rope
passes through the hoist (descent speed) at more than 15 m/min. The overspeed safety device
can also be triggered manually by pressing the manual release button.
To reset the overspeed safety device, first drive the hoist up a few centimetres and then turn
the reset knob clockwise in the direction of the arrow.
9. Use of Handwheel to reset safety device in case of power failure
If the slack rope safety device or overspeed safety device
has been activated and there is no
power to the platform, it will be necessary to wind the hoist up a few centimetres manually, to
be able to reset the safety device.
1. Pull out main power plug to cut off power supply.
2. Remove plastic plug in the motor cover to expose shaft for the hand wheel.
3. Remove the hand wheel from its storage position and insert shaft into hub.
4. Wind the hoist in the up-direction counter-clockwise ½ turn at the same time as you pull up
on the brake lever to open the brake.
5. Release brake lever and repeat.
TIP: Grab the hand wheel firmly while opening the brake to prevent it from turning and going
back down.
6. The overspeed safety device must be reset manually. The slack rope safety device resets
automatically.
7. Put plastic plug back on and return hand wheel to its storage position after use!
8. Plug in main power plug and resume.
