8. Powered hinge
At this moment we have 2 different powered hinges.
The powered sliding hinge needs less space then the powered folding hinge when folded in.
8.1 Powered sliding hinge
The powered sliding hinge uses extra remote-controls for moving the hinge up/down.
A 1-channel transmitter and receiver are used for ‘hinge is down’-command.
The transmitter is battery-buffered via 2x 9V recharge-able batteries on the hinge PCB.
The hinge can only be controlled when a chair is on the charge-point.
It uses the battery of the chair as powersupply.
A detail drawing of the connections of the sliding hinge is attached. (drawing 86900 SS eng)
8.2 Powered folding hinge
The folding hinge is controlled by an extra PCB in the chairlift itself.
When you control the lift on the armrest or on a remote, the extra PCB in the chair (ssp 008 v3)
commands the PCB under the rail (ssp 007 v3) to fold the rail out.
When the hinge has folded out, the PCB near the hinge commands the PCB in the lift that it is safe to
drive.
If the chair is stopped on a charge-point the hinge will fold in automatically.
A detail drawing of the connections of the folding hinge is attached. (drawing 86900 KS eng)
The working of the folding rail is described in chapter 9.9
Note that the transformer is not connected directly to the charge-point, but is (and should be)
interconnected through the PCB ssp 007.
