Elevance® Chair Manual Calibration Test and Repair
Manual calibration is only required to modify one or more of the limits to which the base and back are originally set.
Power to the chair must be cycled after dipswitch #4 is returned to OFF position to complete the procedure.
Base and back movements are monitored by sensors that keep them within a controlled range. Manual calibration is a modified routine allowing technicians to set limits, store the values, then test results.
To manually calibrate a chair
1.Unplug chair from power supply.
2.Remove upper lift arm cover and PC Board cover (two screws). Locate S1 and S2 switches on the PC board.
3.Move dipswitch #4 on the S2 Prog SW to ON position.
4.Plug chair into power supply, press and hold the TEST button on S1 switch for five seconds. Listen for a beep to indicate it is in Manual Calibration mode. Beeps continue, one every 5 seconds, as long as you are in manual calibration.
5.Limits can be manually set or skipped for each of these base and back travel points using the same keypad selections.
|
Limits must be set in this order, one at a time: |
Procedure | |
|---|---|---|
|
Base Low Back High Base High Back Low |
To set a limit: |
|
|
Move base or back to desired limit, then press and hold button 1 for two seconds to set. |
Two beeps indicate limit is set. |
|
|
OR, to skip re-setting any of the current limits: |
||
| Press and hold button 4 for two seconds. |
Two beeps indicate previously set limit remains. |
|
You can abort the manual calibration procedure any time by pressing the TEST button on S1 switch.
6.As soon as the final (Back Low) limit is set, the calibration routine begins. Step back and allow the chair to complete the necessary number of up/down cycles, which takes a few minutes. This is only checking manual limits.
The chair emits a short beep every 2 seconds while calibrating. When calibration is successful, the chair emits three long, confirmation beeps. If calibration fails, the chair emits one long beep at the end of the routine. Repeat entire Manual Calibration.
7.Unplug chair from power supply and move dipswitch #4 on S2 program switch out to OFF position
8.Install Covers.
9.Plug Chair back into power supply.
10.Activate keypad and remote buttons to test operation.
