Adjusting the IES Sensitivity
SwingSmart uses a primary Type-A inherent entrapment sensor (IES) per UL325 Safety Standards. A solid
immovable object blocking the gate will trip the IES and cause the operator to stop and reverse (for two
seconds) and enter safe mode.
The adaptive IES software monitors the average
running motor current while the gate is in motion
and reverses the gate when the current exceeds an
automatically self-adapting average.
The IES display, accessed through the Installer Menu,
allows you to input a number between 0 and 9. The
settings (0 through 6) allow an increasingly higher
threshold (amount of headroom) above the average
current draw before tripping. For IES settings 7
through 9, the current limit is a fixed relatively high
value before the IES will be tripped. The factory
setting is 2, which is adequate for most sites.
CAUTION
Avoid setting the IES sensitivity to a fixed level (7 - 9 setting). The high motor current required
for the IES to trip could cause severe injury or death to people caught in the moving gate.
For IES settings (0 through 6), the motor
current is continually being measured and
the IES threshold automatically set to trip at
the average current plus the additional
“headroom” provided by the IES setting
selected.
To prevent false IES trips, the software
boosts the IES current threshold for one gate
cycle after an IES event, then returns to the
normal sensitivity threshold.
Over time, a gate may sag or a hinge begin to
fail or other site issues, such as wind loading
can occur. As the gate hardware ages and
becomes stiffer, the SwingSmart motor
current increases. A failing hinge or other
gate condition which causes excessive drag
may create the need to use a higher IES
setting level.The higher settings should only
be used on a TEMPORARY basis until the
gate sag or bad hinge is repaired so the gate
swings smoothly with minimum resistance.
