The Inherent Entrapment Sensor (IES)
The IES on HySecurity gate operators is an entrapment sensor that is required by UL 325 as a Type “A”
detection sensor. It is tripped through software programming OR hydraulic pressure settings. It does not
function solely on its own accord and must be connected to the Smart Touch Controller. The sensitivity and
response of the IES when tripped is factory set, but can be adjusted through the Installer Menu items:
• SE (Inherent Sensor sensitivity)
• SS (Inherent Sensor function)
• SR (IES reverse to open)

Description
SE 2
IES SENSITIVITY
1 = max. sensitivity
2 = Default setting
9 = least sensitivity
Adjusts the sensitivity of the internal inherent entrapment sensor
(IES). Available settings are 1 to 9 with 9 being the least sensitive.
HySecurity strongly recommends that you avoid setting the IES
sensitivity higher than 6.
Note: Adjust pressure relief valve on hydraulic operators for security
and gate impact purposes prior to changing IES sensitivity. Refer to
the operator’s manual for steps involved in adjusting the pressure
relief valve setting.
SS 0 (OFF)
IES STOP ONLY
0 = stop, reverse for 2s
1 = stop only
A setting of 0, stops the gate and then reverses its direction of travel
for 2 seconds. To stop gate travel with no reversal, the optional
setting 1 can be selected if the gate operator is at a Usage Class IV
site and assigned a UC 4 classication.
SR 0 (FULL OPEN)
REVERSAL LOGIC
0 = IES reverses full open
1 = 2 second reversal only
The default setting is a 2-second duration reversal if the inherent
sensor is triggered. The optional setting of 0 will cause the gate to
reopen fully if triggered while closing.
