SET IES SENSITIVITY
To comply with UL 325 Safety Standards, CNX
operators are equipped with a Type A, Inherent
Entrapment Sensor (IES). The IES software monitors
the average motor current when a gate is in motion
and reverses direction of gate travel when the
current exceeds a self-adapting threshold. A spike
in motor current can be caused by a collision with a
vehicle, failing gate hardware, extreme wind gust,
or any other force applied against the moving gate.
To set the IES sensitivity for your site follow these
instructions:
1. Press MENU on the Smart CNX Controller.
2.
Press the UP or DOWN arrow to navigate to
ENTRAPMENT SENSOR RESPONSE, press
SELECT.
3.
Press the UP or DOWN arrow to navigate to IES
SENSITIVITY, press SELECT.
4.
Press the UP or DOWN arrow to choose an
IES SENSITIVITY, press SELECT to update the
setting.
Note: Settings 0-8 are adaptive and setting 9 is
fixed.
5. Press BACK until the display shows the operator
status.
6. Run the operator for 3 uninterrupted gate cycles
so the IES can adapt to the new setting.
7. Apply force to the leading edge of the moving
gate to trigger the IES. Gate will stop motion
and reverse for two seconds. “SAFE MODE”
appears on the display.
Note: In Safe Mode, the automatic close timer is
disabled, but any open or close input restarts
gate motion. Safe Mode clears when full travel
reached or Reset button pushed.
Note: A second IES trip before Safe Mode is cleared,
results in an Entrapment Mode Alert which
can only be cleared with a Reset on the
display, an open input, stop input, or stop
button on CNX cover.
