Reverse Sensor (Erd) - Maximum Controls MAX MEGATRON 1400HP Installation And Owner's Manual

reverse sensor (erd)

This operator is equipped with an ERD Sensor - Electronic Reversing Device (Type A) that functions as entrapment protection
according to UL 325 standards. The gate will reverse direction after encountering an obstruction in either the OPEN or
CLOSE gate cycle.
When the gate encounters an obstruction during the CLOSE cycle, it will reverse to the open position and PAUSE the gate. An
input command (press remote button or exit loop) is needed BEFORE the gate will reset and close again.
When the gate encounters an obstruction during the OPEN cycle, it will reverse approximately 6 inches and PAUSE the gate. An
input command (press remote button or exit loop) is needed BEFORE the gate will reset and open again.
For the ERD Sensitivity to function correctly:
• THE RELEASE HANDLE CLAMP MUST NOT SLIP when the gate encounters an obstruction.
• Limit switches must be learned BEFORE adjusting the ERD Sensitivity.

Testing ERD Sensitivity
Allow the gate to strike an immobile object while OPENING and
CLOSING. The gate MUST reverse direction after striking the object.
Increase or decrease the ERD Sensitivity as needed. Repeat this
process until the correct sensitivity is achieved. If alarm sounds
while preforming this procedure,
press STOP BUTTON on Matrix 1
or externally mounted Alarm
Reset button to shut-off alarm.
IMPORTANT:
When satisfied with ERD adjustment,
cycle the gate 3 or 4 times to make sure that the ERD
sensor does not falsely trigger during normal gate
operation. Readjust if this happens.

Position gate half-way open and STOP gate.
This gate position will put the most amount of
resistance on the ERD sensor when gate cycles.
CLOSE gate. If ERD sensor triggers, reduce
sensitivity. If sensor does NOT trigger,
sensitivity is set correctly.
