Adjusting the IES Sensitivity
SlideSmart 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.
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, degrading gate
hardware and other site
issues, such as road settling or
debris on the gate rail
(V-track) can occur. As the gate hardware ages and becomes stiffer, the SlideSmart motor current increases and
this 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, gate track, or wheels are repaired so the gate rolls smoothly with minimum
resistance.

NOTE: When wind load increases, IES soware adapts and changes the threshold allowance. The IES threshold
automacally increases by 50% when the temperature drops below 32°F.
