#9 MAGLOCK RELAY: (NO-COM-NC Relay) - Can be used to control higher powered maglocks
that can’t be powered by the Diamond DC board’s #10 output connection.
#10 MAGLOCK (24 VDC): Provides a 24 VDC and relay output for maglock or solenoid locks.
#11 ALARM (12 VDC): Safety Alarm - If the gate hits an obstruction twice while closing or
opening, the system will shut down for 5 minutes. On the Diamond DC board, you have two
options of reset mode (Feature Selector switch #7):
OFF setting - The system will require a “Manual Reset” of the board after the gate
hits an obstruction twice while closing or opening.
ON setting - The system will automatically reset itself.
#12 POWER (24 VDC): Connect accessories to this when using the POWER SAVE MODE to
maximize operating cycles when AC power is not present. See page 19.

Two-Way Adjustable Reverse Sensor / ERD Emergency Reversing Device
IMPORTANT: The level of sensitivity
has to do with the weight of the gate
and the condition of the installation.
A heavier gate will require LESS
sensitivity and a lighter gate will
require MORE sensitivity.
Only a qualified service technician must make all adjustments to these sensors.
Proper function of reverse sensor (ERD):
When meeting an obstruction in the CLOSING direction, the gate will STOP, reverse direction and return to the FULL OPEN position.
When meeting an obstruction in the OPENING direction, the gate will STOP and reverse its direction and stop again after 4-6 inches. The gate
operator will stay in an “OVERLOAD” state for 5 minutes or until manually reset.
If the gate operator enters overload status two times in a row, the alarm will sound until manually reset.
When adjusting the sensors sensitivity:
TOO sensitive - If the gate stops or reverses by itself.
NOT sensitive enough - If the gate strikes an object
and does NOT stop or reverse.
Fine tune adjustment is ONLY necessary when stopping force
cannot be achieved within normal reverse sensor ERD range.
Three (3) full turns sets ERD in the “Normal Range”:
• Turn Clockwise for MORE force beyond normal range.
• Turn Counter-Clockwise for LESS force than normal range.
The Diamond Control Board has a sensitivity adjustment for the OPENING direction and
CLOSING direction of the gate. Both MUST be adjusted.
Adjustment must be made so that the gate stops and reverses when meeting an
obstruction equal to approximately 20 lbs. of stopping force.
OVERLOAD LED: The OVERLOAD
LED warning light will light up when
the gate is heavier than normal for the
operator. During this warning, the
operator will NOT function properly.
