Enabling the Auto-Close Feature
The Mighty Mule 250 is equipped with a built-in auto-close feature option. The auto-close feature will automatically activate
the Mighty Mule 250 and close the gate if it is left at the open position more than 60 seconds. The auto-close feature comes
disabled from the factory, allowing the gate to remain open until activated by a transmitter, push button or keypad.
To enable the auto-close feature, place the small black jumper connector on the JMP1 plug on the control board as shown in
Illustration "A" below. When the auto-close feature is activated, an audible warning will sound for 2.5 seconds prior to the
gate closing. This audible warning alerts anyone standing close to the gate that the gate is about to move. The audible
warning will only sound if the gate is closed by the auto-close feature, not by keypads, transmitters or other manual control
devices.
IMPORTANT: We recommend leaving this audible warning feature enabled if the auto-close feature is enabled. The audible
warning can be disabled by connecting the jumper to JMP2, see Illustration "B" below. The only reason the audible warning
should be disabled is if it disturbs live stock in a way that would create a safety hazard.
