9.8 Transformer / on board charging-circuit
The main PCB has its own charging-circuit on board.
Because of this we can charge more accurate, which results in a longer lifetime of the batteries.
The maximum charge-current is 1,1A .
The transformer of the type 87 is NOT a battery-charger. You can not and may not use this
transformer for charging batteries directly.
Only use this transformer in combination with the 86900 or 09000 (jade) PCB.
Visa versa, you can not use a standard battery-charger, to charge the batteries when a type 86 main
PCB is connected.
The transformer must be fused with a 1,6 Ampere Fuse (glass-fuse 5x20)
NEVER apply a fuse with a higher value.
Always use the special 24V DC transformer which is delivered by Otto Ooms BV.
9.9 Dipswitches on the circuit board
The dipswitches on the circuit board have their own logic functions.
Dipswitch 1
=>
The rotation monitor unit is monitored on its functionality.
If the rotation monitor (RMU) does not give an alternating signal,
during 30 cm of moving the lift, the lift stops.
The lift will drive further by re-controlling it.
If the dipswitch is off and a rotation monitor unit is connected, the PCB
will see this as an incorrect combination. Every time when the signal
from the RMU alternates the chair is stopped.
Dipswitch 2
=>
Use for future options. (functionality is already implemented)
Dipswitch 3
=>
When the lift has not seen the voltage of the transformer for 1 or 8
hours the lift will go into sleepmode. (low current consumption)
When the dipswitch is on, the sleepmode will be activated after 8
hours instead of the standard 1 hour.
Dipswitch 4
=>
When an extra charge or stoppoint has been programmed, the lift will
stop on this point when it is controlled by a remote-control.
Dipswitch 5
=>
When an extra charge or stoppoint has been programmed, the lift will
stop on this point when it is controlled by the armrest-control.
Dipswitch 6
=>
The beeper will give a continuous alternating alarm signal (1 Hz),
when the lift has not seen the voltage of the transformer for a period of
time after controlling the lift.
When the dipswitch is on, the delay to this alarm is 2 minutes instead
of the standard 15 seconds.
Dipswitch 7
=>
For future developments. Functionality until now not implemented.
Dipswitch 8
=>
Use for future options. (functionality is already implemented)
Dipswitch 9
=>
Depending if a rail is mounted on the left or right side of a staircase
the logic of the remote might have to be reversed.
When the dipswitch is on, the remote-control is adjusted for right rail.
When the dipswitch is in the standard off position the remote-control is
adjusted for a left rail.
