6.0 TRx Switches

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.
