Error Code EN 07. The gate is disabled.
Viewed 1955 times since Wed, Apr 28, 2010
Error code En 07 occurs when there is low AC voltage at the controller. Low voltage AC power must rise above 20VAC (i.e., a 230V operator is wired for 115V). Please contact your local dealer for service. Read More
Error code En 09. The gate is disabled.
Viewed 1945 times since Wed, Apr 28, 2010
Error code En 09 is caused by a compatibility issue with the firmware between the two controllers. A firmware update is required for both paired controllers. Reset both paired controllers. Please contact your local dealer for service. Read More
