3.5 Secondary Current Sensor Adjustment

The PRIMARY gate operator's "secondary reversing sensor" uses a secondary current sensing device (Located only in the
primary operator) to detect any obstructions "physically" encountered in the SECONDARY gate path when using dual gates.
The secondary current sensor uses a sensing coil with a given number of turns through it to monitor the current flow into the
secondary operator. Each time the wire passes through the coil, it is considered a turn. The number of turns through the
sensing coil is dependant on the operating voltage of the operator and the weight of the gate. In general, light weight gates may
require additional turns of wire through the secondary current sensor, while heavier gates may require less turns. CAUTION –
HIGH VOLTAGE: Be sure power is turned OFF before changing the number of wire turns to the secondary current sensor. When
you are setting the secondary reverse sensor (section 3.4 on the previous page) and reach the MAXIMUM sensitivity position
on the reverse sensor without activating the secondary operator reversing function, add an additional turn of wire through the
secondary current sensor. If you set the secondary reverse sensor to the MINIMUM sensitivity position and the gate will not
cycle completely, reduce the number of turns through the secondary current sensor.
