Adjusting the Tilt Potentiometer
NOTE: For this procedure, refer to FIGURE 14.7 on page 153.
NOTE: The tilt potentiometer is adjusted at the factory for 20° drive lockout and should not require
further adjustment. However, if it becomes necessary to adjust the tilt potentiometer, the following
procedure may be used.
Adjusting a Tilt Potentiometer Used With a TRSS
To adjust the tilt potentiometer on a seating system with a single function toggle switch,
follow these steps:
NOTE: A single function toggle switch can only be used in conjunction with a tilt only seating
system.
1. Loosen the set screw on the tilt potentiometer. Refer to Detail “A”.
NOTE: Loosening the set screw enables the tilt potentiometer to be adjusted independently of the
chair seat movement.
NOTE: The up and down directions are noted on the front face of the single function toggle switch.
2. Push the single function toggle switch in the down direction and verify that the seat
tilts back.
3. Push the single function toggle switch in the up direction and verify that the seat raises
to the upright position.
4. Tilt the seat back 20° from the vertical position. Verify angles by using magnetic
protractor (available at any hardware store).
NOTE: 20° from the vertical position is the angle at which drive-lock out should occur.
5. Disconnect the single function toggle switch connector from the actuator connector.
6. Push and hold the single function toggle switch in the up direction.
7. Turn the tilt potentiometer clockwise until it stops.
8. Verify that the drive lock-out light on the single function toggle switch is NOT
illuminated.
9. Push the single function toggle switch in the down direction and verify that the drive
lock-out light on the single function toggle switch is still NOT illuminated.
10. Holding the single function toggle switch in the down direction, turn the tilt
potentiometer counter-clockwise until the drive lock-out light is illuminated.
11. Release the single function toggle switch.
12. Tighten the set screw on the tilt potentiometer.
13. Apply Glyptal to top of set screw to secure in place.
14. Reconnect actuator and single function toggle switch.
15. Tilt the seat up and down to confirm that the drive lock-out light illuminates on/off
when the seat angle passes through the 20° lockout angle.
