Switching The Stairlift On And Off; Charging The Batteries - Access Flow2A Manual

The drive unit
Because the stairlift works on batteries it can still be used when there is a power failure. The battery voltage is
monitored by the microprocessor on the control board.
With fully charged batteries at least 10 trips can be made, depending on various factors such as rail length, user
weight and the age of the batteries. To safe battery charge the stairlift will enter a sleep mode when not in use for 2
minutes.
When the charge of the batteries becomes less than 19V during movement of the stairlift, the stairlift will stop
moving and an error will be given with an audible signal. The ELD can be used in this situation in a downwards
direction.
The batteries are connected in series (2x12 = 24 Volt) to the control board. On the control board the power supplies
for the other parts of the stairlift are generated.

Switching the stairlift on and off

At the rear of the drive unit is the main switch. With this the stairlift can be switched on or off when it does not have
to be used (e.g. during holidays).
Figure 4-17: On/off switch on drive unit
A blue light on the front of the drive indicates if the lift is on and ready for use.
If the transformer is un-plugged the stairlift will drain the batteries slowly, but a warning signal is given by the drive
that there is no charging contact available for at approximately 2 minutes. Then the stairlift will go in sleep mode.
