Nice HySecurity SlideSmart HD - Adjusting the IES Sensitivity

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 threshold.
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 xed
relatively high current value before the IES will be
tripped. The factory setting is 2, which is adequate
for most sites. See Figure 44 and Figure 45
For IES settings (0 through 6), the motor current is
continually being measured and the IES threshold
automatically set to trip at peak motor 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 minimal resistance.
CAUTION
Avoid setting the IES sensitivity to a xed 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.

Examples of conditions which affect IES sensitivity
include:
Gate design - For long and/or solid gates in windy
environments, large variations in motor current
may occur. In these types of scenarios, you may
want to use a higher (less sensitive) IES setting.
Gate condition - If the gate environment is near
salty sea air, rusty wheels or chains might impede
gate travel over time. Additionally, gates that are
hit and bent may have very stiff areas during travel
that cause a large variation in motor current. For
these issues, you may want to use a higher (less
sensitive) IES setting until repairs are made.

NOTE: When wind load increases, IES soware adapts and changes the threshold allowance. The IES threshold
automacally increases by 50% when the temperature drops below 32°F.
NOTICE
When changing the IES setting, consider the
site design and vehicular gate traffic. It is
recommended that you use the most sensitive
setting while still allowing for reliable gate
operation.
