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.
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.

Turn knob until blue LED lights up.
Max sensitivity reached, Position 1.
“
1”
- Maximum sensitivity setting.
Too sensitive for most gates. (LED lights)
“
16”
- Minimum sensitivity setting.
Not sensitive enough for most gates. (LED is off)
B.
Turn knob
counter-clockwise
to reduce
sensitivity during ERD testing as needed.
(LED remains OFF for all but position 1)
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.
When solid gates are installed in:
•
Unusually high wind areas
•
Uphill opening gate
•
Heavy gate
ERD sensor can be set to
Min
(position 16)
to keep the gate cycling normally in such
extreme conditions.
CAUTION:
Minimum sensitivity setting
(position 16) results in gate exerting
MAXIMUM force
before reversing direction.
