Limit Programming

Before the garage door operator can be used, the door limits have to be programmed.

This is an automated process, that involves little user input. Assuming the system has

powered up correctly (no beeping) the limits can then be programmed by following the

procedure in the following sections.

In the factory shipped state, the system will only accept a Limit Setup

command, all triggers are ignored until the door is set up correctly. This

is not a fault, it is for your safety.

To invoke Limit Programming

1. Close the roll-up door completely and ensure that the door seats properly on the

floor. Ensure the door is ENGAGED. If you cannot lift the door, it is engaged, if

not, pull the mechanical release cord until the door is locked.

2. Remove the wall console cover, and press and HOLD SET, until a beep is heard.

The door will begin to open slowly.

When running the Limit Programming utility, please ensure that the

batteries have had sufficient time to charge (usually 3-4 hours from the

factory) and that the batteries are connected. Performing Limit

Programming without batteries connected is not permitted, and will lead

to product failure.
