Pre-Power Up Checks; Power-Up Sequence - Acorn 80 Installation Manual

SECTION 8
Programming

8.1.1 Pre-power Up Checks

Remove the front cover and check that all
programming switches are in the off position, to the
left. Select LEFT or RIGHT hand install. Check that
the correct hand has been selected, as these switches
should not be changed at all from now.
8.1.2 Power Up Sequence
Check that the seat holding switch is switched off. Connect the positive leads from both batteries to the
positive spade connectors on the board. The board will display the bottom right hand corner decimal point.
Switch on the seat holding switch. The selected hand of the lift will be displayed momentarily, then the
no datum set symbol will be displayed. The lift cannot be moved with this displayed.
8.1.3 Calibrating The Levelling
ONLY TO BE DONE IF THE PCB HAS BEEN CHANGED. Now switch the PROGRAM MODE to ON.
Datum search will be displayed. Call the lift with either the rocker switch or the remote in either
direction. Using a spirit level on the footrest, finely adjust the potentiometer until the lift is level. Once
the level position is set, the potentiometer should not be altered after programming or the whole rail
MUST be programmed again.
8.1.4 Programming The Top Terminal Limit
Call the lift down off the charge point. As the positive charge plunger leaves the charge point, the
programming rail symbol will be displayed. This sets the "datum point".
This is a reference point for the memory during programming of the rail. Stop the lift and drive
it back up onto the final limit striker. will be displayed. Note that the top terminal limit will be
approximately 10-15mm down from the final limit stop position. Adjust the striker to the required
position. This position depends on the angle of the rail at this point. When the correct position is
found, call the lift down the rail off the charge point, and then back up onto the final limit for a
second time. The carriage is now ready for programming down the full length of the rail.
