Diagnosing EN 07 code on APeX controller

EN codes are the APeX controllers primary way of signaling an entrapment condition with the system. These codes range from EN 00, to EN 14. We will discuss each of these codes, their meanings, and possible solutions in periodic blog posts. Comments and questions are welcomed and encouraged to help you understand the automatic gate system you are working on as thoroughly as possible.



The EN07 code is activated any time the APeX board detects low or no incoming voltage to the system. Any previous blog posts can be found here.

 

When an EN07 error occurs, a lockout condition is present due to low incoming voltage detection from the APeX board due to AC power loss. This error will trigger either Fail Safe, or Fail Secure (depending on how the automatic gate system is programmed) either immediately, or when the batteries drop below 21.6VDC (dependent upon programming option).


When triggered, this input will display "EN 07" on the APeX display, and will have the "LOCKOUT" LED lit preventing movement of the gate until AC power is restored.


To reset this error code and return the automatic gate system to normal operation, check with the property manager or owner to test the breaker and ensure incoming AC voltage is adequate. AC voltage should read between 110vac and 125vac on a digital multimeter.


Once all voltages have been checked and are correct, press the "RESET" button on the bottom of the control box, or the "STOP" button next to the display on the APeX board; this should reset the error. You can now test run the slide gate system and check for normal operation.


If the problem persists after checking these devices and wiring, contact your installing dealer, distributor, or Rotary Gate Systems for further troubleshooting or replacement parts.

All error codes, and diagnostics can now be managed remotely with the Rotary IQ. This system is designed to work with all gate operators using the Linear APeX circuit board from 2008 to present and allows installing dealers a look at what is happening with a gate opener before making a trip on site, saving time and money.
