Switch Operation Mode
By default, DIN Rail is programmed for a latching switch. If you are installing DIN Rail behind a single momentary or
dual momentary switch, you must change DIN Rail’s local-control switch operation to single momentary mode or dual
momentary mode.
Change Mode
1) If installing a single momentary or dual momentary switch, change mode as follows
a) Press and hold set button until it beeps
LED will start blinking green
b) Press and hold set button until it beeps a second time
LED will start blinking red
c) Press and hold set button until it beeps a third time
LED will start blinking green
d) Perform the step that applies
• For single momentary: slowly tap set button four times
LED will continue blinking green
• For dual momentary: slowly tap set button five times
LED will start double-blinking green
• To switch back to latching: slowly tap set button six times
LED will start blinking green
e) Once the mode is selected, press and hold set button until it double-beeps
LED will stop blinking and turn green if load is on or red if load is off
2) Test mode change by following the switch actions in the Latching, Single Momentary, or Dual Momentary tables
below
Load will respond appropriately
3-Way Toggle Mode (Latching Switches Only, Default)
Because DIN Rail module comes programmed for latching switches, 3-way toggle mode is enabled by default.
Normally, a latching switch reads the switch’s up position as on and down position as off. For example, if you turn
DIN Rail module on from the latching switch and off from another controller, the switch is still in the up (on) position;
turning DIN Rail module back on from the switch would require you to tap the switch down, then up again.
The 3-way toggle mode overrides this sense feature, so in that same scenario—turning DIN Rail module on at the
switch and off from another controller, so switch is in up (on) position—you could then turn DIN Rail module on at the
switch by tapping it down.
If you are installing DIN Rail module behind a single or dual momentary switch, 3-way toggle mode is ignored. If
desired, you can disable (or re-enable) 3-way toggle mode by performing these steps:
1) Press and hold set button until it beeps
LED will start blinking green
2) Press and hold set button until it beeps a second time
LED will start blinking red
3) Press and hold set button until it beeps a third time
LED will start blinking green
4) Press and hold set button until it beeps a fourth time
LED will start blinking red
5) Tap set four times button
DIN Rail module will beep
LED will start double-blinking red
6) Press and hold set button until it double-beeps
LED will stop blinking
3-way toggle mode is now disabled (or re-enabled)
