ADJUSTING THE IES SENSITIVITY
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.
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.
Gate maintenance - Gate rollers will deteriorate and begin to fail over time. Gravel or dirt roads will
incur more debris in the gate rail or inverted V-track than a paved surface. In poorly maintained gate
areas, the chance for false IES trips is higher.
To adjust the IES sensitivity, take the following steps:
1� At a gate status display, press the MENU button twice. The CLOSE TIMER display
appears.
2� Simultaneously, press the OPEN and RESET buttons to enter the Installer Menu.
Release the buttons and the LEARN LIMITS display appears.
3� Press NEXT until the IES SENSITIVITY display appears. The factory default setting is 2.
4� Use the SELECT and NEXT buttons to navigate and change the number on the display.
5� To exit the Installer Menu, press the MENU button. The gate status appears in the display
indicating you have returned to Run Mode.
If IES errors occur, SAFE MODE or ENTRAPMENT MODE will appear on the display. For more information
about troubleshooting, refer to “SmartDC Controller Troubleshooting” on page 151 .
