Normal Mode vs. Auto-Reversing Mode

TRx Push Buttons and Toggles can be set up to operate in “Normal” or “Auto-Reversing” mode.

i)Normal Mode: two switches are required for each function, one for each direction.

ii)Auto-Reversing Mode: only one switch is required for each function. In this mode, pressing the switch once will activate the function; releasing the switch, waiting for two seconds and then pressing it again, will cause the reverse direction of this function to occur.

Tables A. and B. below show a comparison of Normal Mode vs. Auto-Reversing Mode when using a tog- gle and/or a push button to control the tilt function of a power positioning system.

Table A. - Using a single toggle to control the tilt function:

		Pulling the toggle back will cause the seat to tilt
Normal	Mode	back. Pushing the toggle forward will cause the
		seat to tilt forward.
		Pushing the toggle forward will cause the seat to tilt
Auto-	Reversing	back. Releasing the toggle to its rest position, wait-
		ing for two seconds, and pushing it forward again,
Mode		will cause the seat to tilt forward. (This set-up allows
		the rearward (pulled back) toggle direction to be used for
		a separate power positioning function (e.g. Recline)

Table B. - Using a dual push button to control the tilt function:

		Pushing the first button will cause the seat to tilt
Normal	Mode	back. Pushing the second button will cause the
		seat to tilt forward.
		Pushing the first button will cause the seat to tilt
Auto-	Reversing	back. Releasing the button (rest position), waiting
		for two seconds, and pushing the same button
Mode		again, will cause the seat to tilt forward. (This set-up
		allows the second push button to be used for a separate
		power positioning function (e.g. Recline)
