Gate motor installed and remotes and app works. The gate closes fine, but then will only open about 6 inches. We moved the limit switch to try and adjust it and whatever we do it only opens about 6 inches. P.S. We did the "learning" part with the gate partially opened and it closes all the way but then will only open a tiny bit.

The TMT Automation Clifford 400 gate motor may only be opening 6 inches after installation due to one of the following reasons:
1. Limit Switch Settings – The Clifford 400 has two adjustable limit switches that control the stroke of the gate opener. If these are set incorrectly, they may be limiting the opening distance.
2. Obstruction or Resistance – Check if there is any physical obstruction or resistance preventing the gate from moving past 6 inches.
3. Power Supply Issues – Ensure the motor is receiving the correct 24V DC power supply and that there are no wiring issues.
4. Improper Installation of Rear Bracket – The adjustable rear bracket must be installed correctly to allow full movement of the gate.
5. Motor Load Capacity – Verify that the gate does not exceed the motor’s maximum specifications (20 ft length, 1000 lbs weight).
6. Manual Release Engaged – Ensure the manual release is not engaged, as this could limit the motor’s function.
Checking these factors should help identify and resolve the issue.

Safety Overview ------Important Instructions-------- Thank you for choosing TMT Automation® Automatic Gate Opener System, a leader and innovator in the field of gate automation systems. This manual will guide you through the steps of installation and maintenance. PLEASE READ AND FOLLOW THE STEPS CAREFULLY TO REDUCE the risks of injury or death.
I. Before Installation The terms gate opener and gate operator will be used interchangeably. 1. Please make sure your gate is in proper working condition: a. The gates should be level, firm and able to swing freely in both directions. b.
II. During Installation 1. Be aware of moving parts. Moving parts could pinch hands and fingers. 2. The gates should not open into public access areas to prevent unwanted collisions and injuries. 3. Do not install the gate opener in an area that the public has access to; the gate openers can be tampered with and cause security and other dangers.
Product registration is required, or warranty is in effect starting from the date of purchase. TMT Automation will, at its discretion, provide replacements for any defective parts within the terms of the warranty, free of any charge.
Tools Needed Below is a list of tools recommended for installation. Please have them prepared before you start your installation to save time. Adjustable wrench Philips Screwdriver Flathead Screwdriver Pliers Level Hammer Wire Stripper Drill Bits Tape Measure...
Installation I. Preparing the Gate Prior to installing the automatic gate operator, make sure of the following: 1. The gate should swing freely, smoothly and leveled. 2. The gate should be able to hang without support from wheels. It is Center Mount recommended that gates weighing above 250 lbs.
7. Find a suitable location to mount the control box and battery box. The control box and battery box should be in range of both gate operators. They should also be at least a foot above the ground to avoid splash and moisture damage. 8.

II. Pull to Open Installation 1. Mark out the positions for the gate opener. Make sure that the mounting spots on the post and the gate are leveled to the ground. You may want to use a Sharpie or tape to mark your positions.
Page 11
4. Use the clamps to notch the mounting brackets to the post. The center of the mounting bracket should align with the center line as labelled in the diagram in Step 1. Mark the positions where the mounting brackets should latch on to the post. 5.
Page 12
7. After you have set the angle, insert the bolt and washer to set the angle of the mounting bracket. 8. Once the positions of the mounting brackets are measured and checked, you can now drill holes to fasten the brackets. You may want to keep the clamps to hold the post mounting brackets in place, and slowly drill one hole at a time.
III. PUSH to OPEN Installation 1. To have a push to open gate, make sure that you will not be at risk of colliding into pedestrians or oncoming traffic. 2. Mark out the positions for the gate opener. Make sure that the mounting spots on the post and the gate are leveled to the ground.
Page 14
5. Use the clamps to notch the mounting brackets to the post. The center of the mounting bracket should align with the center line as labelled in the diagram in Step 2. Mark the positions where the mounting brackets should latch on to the post. 6.
IV. Control Box Installation 1. After determining the position of the control box, you may want to use the clamps to mark up the position of the holes and help you secure the box. Note that the control box should be at least one foot from the ground and within five feet of at least one of the gate operators.
4. There should not be any exposed strands of wires, and the screws should screw into wire and not the wire insulation. 5. If you have more than one opener, repeat the process for the other gate opener. Note that for the second set of openers, you should connect to a terminal block that is different from the one that the first opener is connected to.

5. The negative terminal of the battery should be connected to the black wire, and the black wire should be connected to the slot labelled BAT-. It is recommended that you connect the negative terminals before the positive terminals. 6. The positive terminal of the battery should be connected to the red wire, and the red wire should be connected to the terminal labelled BAT+.
VII. Connecting the Control Box to an AC Adapte 1. Make sure the power switch for the control board is in the OFF position. DO NOT connect the AC adapter to a power source until you have finished wiring the adapter to the control board. T h e A C A d a p t e r u n i t c o n s i s t s o f a n A C transformer block, an adapter wire to the control board and an adapter wire to the outlet.

3. The mounting brackets are equipped with a notch that can fit into the holes on the curved pipe, as seen below. If you want to change the orientation of the panels, drill a hole through the mounting brackets and pipe and secure with a screw. Make sure the power switch for the control board is in the OFF position before attempting to connect the solar panels.
IX. Setting Limit Switches 1. To set limit switches, first remove the screws at the end of the operator. 2. After removing the screws, you can remove the top cover. You should be able to see the actuator inside and the limit switches that run along rails at the top. Unscrew the screws on the limit switches as shown below, this will allow you to move the limit switches.
Control Board Setup Before attempting to set up the control board, always make sure that the power switch is turned OFF. Below is a diagram of the control board. I. PUSH/PULL SWITCH The PUSH/PULL DIAL controls the direction in which the gates open. If you have set your gates to being PUSH-to-OPEN, set the dial to the OFF position;...
STALL FORCE We recommend you set the stall force in accordance with the conditions at hand. If you live in an area with high winds or debris that may affect the travel of your gate, you can increase the stall force as needed.
Pairing Remotes I. Using Factory Remotes To pair the factory remotes that comes with the kit, follow the instructions below: 1. Make sure that the control board is properly powered: the batteries should be connected and have sufficient voltage. (LED2 should stay on) 2.
III. Connecting with Other Controllers Our control board uses a 433 MHz RF receiver. It offers limited compatibility with other remotes that use 433 MHz bandwidth. IV. System Learning Using the Controller 1. First, you must first pair at least 1 remote control 2.
VII. System Reset Via Remote The remote is capable of resetting the system. To do this, you can hold Button 3 and Button 4 simultaneously for 10 seconds. When the system is restored to the factory setting, the POWER LED will flash for 5 seconds before returning into the blinking state to indicate that system learning has yet to be completed.

4. What does the APP OVERRIDE dial do? When you have the dial set to the APP OVERRIDE ON position, then the Chow! App will be in control of all the settings. No matter what how the control board is set, the settings on the App will have priority unless the dial is switch back to the APP OVERRIDE OFF.
Manual Operation In the case of an emergency, the operator can be manually operated. Please keep the key that came with the operator, for it is essential in disengaging the operator. I. To Disengage Motor Gear 1. Open the cover as shown. 2.
