SECTION 3 - ADJUSTMENTS
The switch settings and adjustments in this chapter should be made after your installation and wiring to the operator(s) is
complete.
Whenever any of the programming switches on the circuit board are changed, power must be shut-off, and then
turned back on for the new setting to take effect.
3.1 4405 Circuit Board Descriptions and Adjustments
Auto-close timer
(when turned on)
SW 1, switch 4.
Time Delay:
Adjust from 1 second
(full counter-clockwise)
to approximately 23
seconds (full clockwise).
Self-test mode is for
bench checks ONLY!
The operator will
continually cycle the gate.
The jumper must be set
at normal mode for
normal operator function.
Set the DIP-switches on
the circuit board to the
desired setting. See
switch-settings on next
2 pages.

Input LEDs
should be OFF and will
only illuminate when the input is
activated.
Limit LEDs
will only illuminate when
the respective limit sensor has been
activated.
Loop LEDs
will only illuminate when a
reverse, shadow or exit loop is
activated (Vehicle passing over a
loop).

Primary Current Sensor
Uses a sensing coil with a given
number of wire turns through it
to monitor the current flow of the
primary operator motor.
Factory Set:
1/2 HP Motor - 2 Turns
1 HP Motor - 1 Turn
Secondary Current Sensor
Uses a sensing coil with a given number of
wire turns through it to monitor the current
flow of the secondary gate operator motor.
Factory Set:
1/2 HP Motor - 2 Turns
1 HP Motor - 1 Turn
