3.5 Speed Control (9220, 9230 Only)
The models 9220 and 9230 are equipped with
a speed control module that allows you to
adjust the speed of the gate from 1/2 to 2 Ft./
Sec. To adjust the speed, simply rotate the
speed control knob clockwise to increase the
gate speed, or counter clockwise to decrease
the gate speed. The digital readout on the
speed controller will display the gate speed.

3.6 Current Sensor Wiring
This vehicular gate operator uses a current
sensing device to detect any obstructions in the
path of the opening or closing gate. The current
sensor uses a sensing coil with a given number of
turns through it to monitor the current flow into the
operator. Each time the wire passes through the
coil, it is considered a turn (see diagram below).
The number of turns through the sensing coil is
dependant on the operating voltage of the
operator, the speed of the gate and the weight of
the gate.

230 Single Phase 2
208 Three Phase 5
230 Three Phase 6
460 Three Phase 7
In general, light weight gates may require additional turns of wire through the ERD sensor, while
heavier gates may require less turns. In addition, the speed of the gate can affect how the ERD
sensor works. Gates running at a higher speed may require less turns of wire through the sensor.
CAUTION – HIGH VOLATGE: Be sure power is turned OFF before making any wire
adjustments to the ERD sensor.
If you are setting the ERD sensitivity (section 3.4) and reach the full sensitive position without
activating the reversing function, add an additional turn of wire through the current sensor. If you are
decreasing the sensitivity and the gate will not run properly, reduce the number of turns through the
current sensor.
