ADJUSTING THE IES SENSITIVITY
Adjusting the IES Sensitivity
FoldSmart uses a Type-A inherent entrapment sensor (IES) per UL 325 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.
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
FoldSmart 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.
NOTE: When wind load increases, IES software adapts
and changes the threshold allowance. The IES threshold
automatically increases by 50% when the temperature
drops below 32
°
F (0
°C) .
