Action
1. Rotate Load pot to new
sensing level.
2. Press and release Set button
to test level
3. After audible confirmation.
The load sensing level will also be confirmed audibly on any initial trigger after a full power up or manual
If a collision, obstruction or hindrance is encountered before the full open position is reached while opening, the gate will stop, back off and
wait for the next trigger input, before closing slowly. The status LED will flash rapidly once stationery after backing off of collision. Closing
trigger clears the status LED indication. For trigger responses see page mode selection on page 23.
If a collision, obstruction or hindrance is encountered while closing, the gate will stop and reverse to the fully open position. The status LED
will flash rapidly once stationery after opening away from the collision. The next trigger input starts the gate closing slowly. Closing trigger
clears the status LED indication. For trigger responses see mode selection on page 24.
On encountering 4 consecutive obstructions while closing the gate, the UMPETHA will not reverse back to the full open position. The response
will be a 5 sec beep tone, followed by a gentle momentary reverse away from the obstruction. The unit will now begin a mandatory 30sec
lockout whereby the only response to any trigger input will result in a tone so long as the trigger button is held. After 30sec a trigger input will
result in a repeat of the 5 sec beep and the gate opening 1 meter or to the full open position whichever is reached first. The unit will once
again lock out. This time the user must manual release the unit and test the travel by hand before attempting any further automation of the
gate.
The Status LED will flash rapidly throughout this procedure indicating a multiple obstruction lock-out has occurred.
Releasing the gearbox and re-engaging it will clear the LED status and the multiple obstruction lock-out routine.
If no limit input is made when expected (as calculated by the programmed run time) the UMPETHA will not reverse back to the open position
as it normally would when obstructed. It will however stop at the point of impact with the closed catch and emit a 5sec long beep tone. At
the next valid opening trigger the UMPETHA will re-emit the 5sec long beep tone and only open the gate by ±1 meter. This will allow for the
user to be able to enter the property and manually override the gate. The magnet actuator and limit can now be checked. If not
corrected and further attempts are made to operate the UMPETHA with a faulty closed limit condition the same routine will be repeated on
every operation.
If the user continues to attempt to operate the gate without manually releasing the gearbox while the gate is at the ±1meter position, the
result will only be a repeat of the 5sec beep tone.

Beeps confirm successful change
1 beep = 5kg resistance (Default)
2 beeps = 10kg resistance
3 beeps = 15kg resistance
4 beeps = 20kg resistance
5 beeps = 22kg resistance (max)
