The LockMaster LM901 remote may not open your door if the remote control transmitter and the gate opener receiver are not programmed to a matching code. To resolve this, you need to program the remote to the opener:

1. Ensure the Digital Display indicates "PC."
2. Press and release the "INC" button, and the Digital Display will indicate "Ln."
3. Press the key on the remote control twice.
4. Wait for "PC" to display on the Digital Display after "Ln" flashes for 4 seconds, confirming the opener has learned the code.

Repeat these steps if necessary for additional remotes.

The desired position for Limit Switch B on the LockMaster LM901 is at the fully closed position of Gate 1. To set it, pull Gate 1 to its fully closed position, use a cross point screwdriver to unscrew Limit Switch B, slide it to the desired position, and then fix it in place.

The magnetic ring must always be placed between Limit Switch A and Limit Switch B.

  • Page 10: Preparation For Installation

    Preparation for Installation The proper position of the post brackets is a decisive factor to the efficiency and leverage of the gate opener. The distance (usually it is 2.5cm /1 inch or more) between the gate opener and the gate is also determined by the proper position of the post brackets.
  • Page 11: Determining The Position Of Mounting Hardware

    Both round and square post can be used because of the curved design of the post brackets. When mounting the post brackets, use bolts long enough to pass through the entire post. When mounting the post brackets to wooden posts, a larger-size washer or metal plate should be used between the bolts and the wood post to ensure the stability of the fastening hardware when thrust is used.
  • Page 12 Step 2 Attach the gate bracket and post bracket assembly to the opener by inserting a clevis pin. Secure the clevis pins using the hairpin clips. Step 3 With the gate in their desired open positions (from 0° to 100° from the gate’s closed position) and with the opener in their retracted positions, place the opener with the gate bracket and post bracket assembly on the gate post and the gate.
