LiftMaster Mega Arm barrier gate openers might have a built-in timer function for automatic closing. Here's how to set it, but keep in mind some details:

Model Dependence: This information applies specifically to Mega Arm models with DIP switches for configuration. If your Mega Arm uses a different configuration method, consult the user manual for your specific model.

Limited Functionality: The timer function might be for automatic closing after the safety sensors detect an obstruction and the arm re-opens, not necessarily a general closing timer after every opening.

Safety Precaution: Using a timer for automatic closing without additional safety measures (like loop detectors or photo beams) is a safety hazard. Make sure to prioritize safe operation over automatic closing, especially in high-traffic areas.

Here's how to set the timer using DIP switches (if applicable):

Locate the DIP Switches: These are small physical switches usually found on a circuit board inside the operator housing. Refer to your user manual for the exact location in your model.

Identify Switch S2: Among the DIP switches, locate switch S2 specifically. The manual should have a diagram or description to help you identify it.

Focus on Switches S2-1 to S2-5: On switch S2, there are individual switches numbered S2-1 to S2-5. These switches control the automatic close timer delay.

Adjust the Timer Delay: Each switch (S2-1 to S2-5) represents a certain time increment (likely in seconds). Consult the user manual for the specific timing assigned to each switch (e.g., S2-3 ON might be 3 seconds). By turning the switches ON or OFF in various combinations, you can set the desired delay for automatic closing after the arm re-opens due to obstruction detection.

Remember:

Refer to your LiftMaster Mega Arm user manual for specific instructions and switch configurations related to your model.

Prioritize safety over automatic closing. Employ additional safety measures like loop detectors or photo beams if using the timer function.

If your Mega Arm model uses a different configuration method or you're unsure about the process, consult the user manual or contact LiftMaster support for clarification.
