4.1
Main switch
The main switch (red key) is located inside the platform, behind the cover (p.7, item
4). The key can be removed by turning it anti-clockwise, thus disconnecting the
power supply. (For opening the cover, sees 4.7.1). The main switch must be actuated
by technical personnel.
Deep discharge protector and charging
4.2
The LL12 platform lifts are equipped with automatic battery chargers. Charging takes
place automatically when the platform lift drives into a loading station. The batteries
do not require any care.
All LL12 platform lifts are equipped with an acoustic deep discharge protector. This
acoustic signal generator is intended to protect the batteries against deep discharge.
If the battery voltage drops below 22 V, a beep sounds at intervals of approx. 5
seconds. In this case you should drive immediately to the next charging station – if
possible the lower charging station – and allow the lift to charge up there for several
hours (this takes place automatically in the charging station). The beep stops after
proper charging. The sound can be turned off by pressing the emergency stop button;
this has no influence on the charging process.
Checking the loading / overload protection
4.3
The LL12 platform lift is equipped with an overload protector (acoustic and visual).
On activation the orange lamp on the hood goes out (p.7, item L2). In addition, the
internal beeper emits a continuous tone in the case of overload. This is based on the
entire load being in the centre of the base of the platform. Reduce the weight if the
overload protector is triggered. It may be sufficient just to shift the weight towards
the running rail.
4.4
Battery charger (indicator lamps)
The indicator lamps on the battery charger indicate the respective condition of the
battery charger. Distinction must be made between different versions of the battery
charger.
The meaning of the various colours or indicator lamps is shown on the battery
chargers. The installer will explain this to you in detail once again during the
instruction.
Note: An acoustic signal sounds if the lift, outside a station, is not charged 30
seconds after the last motor movement.
