The control system
Concens C3-controller
Introduction
The electric actuators for tilt, recline and leg rests on electrically operated chairs are
managed by a C3-controller. The controller can recognize and be used with up to 10
remotes. Each remote has a unique ID-number, so each C3-controller can have its own
remote without disturbing other controllers in the same room - see note 1.
Inserting and ejecting the battery
The C3-controller uses a compact environmentally-friendly NiMH battery, which is fixed
in the C3-housing by strong magnets. Before inserting the battery, clean the magnetic
poles for dirt. Insert the battery in the housing and turn the battery to align the dots of the
housing and battery. To eject the battery, turn 90 degrees to the right or to the left.
Charging the battery
The battery has to be charged in the supplied C3-charger. A full charge takes normally
about 5-8 hours, depending on state of charge. A NiMH battery can be charged although it
has not fully discharged without decreasing the lifetime. When connecting the C3-charger
to the mains, the yellow diode lights up continuously and there is typically a single flash in
the green diode before it turns off again. By inserting the battery, the green diode flashes
once each second while charging the battery. After finishing charging, the green diode
stops flashing and lights up continuously, the battery can now be removed and is ready for
use.
Start-up of controller
Push in the battery (2) in the C3-housing (4) and turn the battery to align the 2 dots. On
correct installation of the battery you will hear a buzzer-sound for about 5 seconds while
the C3-controller initializes. Thereafter C3 is ready for operating. Occasionally there will be
sounds after the initializing.
2 long sounds
- Battery power level is too low. Battery has to be charged.
5 short sounds
- It’s not possible to run the C3 controller due to lack of power. Start-up is not possible
before the battery has been recharged.
