What are Limit Settings?

Limit settings are the fully down/closed setting and the fully up/open settings. The down/closed

limit setting is the setting that stops the garage door in the fully down/closed position. The

up/open limit setting is the setting that stops the garage door in its fully up/open position.

Using a step ladder locate the Limit Adjustment screws on the side of the control panel on the

Guardian 315 Core Series 1/2 Horse Power garage door opener. Make sure the trolley is

engaged before you start setting the up/open and down/closed limits. Use caution while using

the step ladder to prevent accidental falls.

Programming the Up/Open limits:

For the Guardian Model 315 Core Series 1/2 Horse Power Garage Door Opener first operate the

garage door one full up/open and down/close cycle by pushing the wall button or the button

programmed for this opener on your remote.

If the door opens and closes to the desired

positions without unintended reverse, you will not need to make any adjustments to the

Guardian 315 unit. If the garage door does not travel up/open or down/closed to your desired

locations or you experience an unintended reverse, follow the listed instructions.

Adjustments to the up/open and down/closed limits can be increased(+) or decreased(-) by

turning the corresponding adjustment screw using a flat head screw driver.

*Note: One full turn of the adjustment screw is equal to approximately 2″ inches of actual

garage door travel.

Testing Safety Reverse Setting on Guardian Model 315 Core

Series 1/2 Horse Power Garage Door Opener.

The Safety Reverse Setting is the setting that tells the garage door opener to reverse when

the center of the garage door.

programmed for this garage door opener to close the garage door.

The garage door must reverse within 1 1/2 seconds after striking the 2X4 or other

similar object and then stop in the fully open position.

If the garage door does not reverse and stops on the 2X4 or similar object, (+) increase

the down/close travel limit set screw 1/4 turn.

Step 6:

Complete steps 1-5 until the garage door reverses upon contact with the 2X4 or

similar object.

Step 7:

Remove the 2X4 or similar object and run a minimum of 3 test cycle open and close to

confirm the adjustments are proper.

Up/Open and Down/Close Force Adjustments

The Up/Open and Down/Close Force is the amount of force needed to open and close the

garage door. The Force Adjustment Buttons are found on the back of the Guardian 315 Core

Series 1/2 Horse Power Control Panel. The Force Adjustments allow you to compensate for

minor resistance caused by climate, weather and other means.

On the Guardian 315 Core Series garage door opener the force is preset at 6 however the

settings range and can be adjusted to any of 1-12 levels of force for either Up/Open or

Down/Close.

If the Down/Close Force is set too low the garage door will reverse during closing. If the

Up/Open force is set too low the opener will stop the garage door while opening.

Never adjust the force level more than 1 level (+) increase or (-) decrease at a time.

Setting Down/Close Force

Step 1:

Start with the garage door in the fully open position.

Step 2:

Close the garage door by pushing the wall button or the button on your remote

programmed for this Guardian 315 Garage Door Opener.

Step 3:

If the garage door closes without reversing, press the Close Force (-) Decrease Button 1

time.

Step 4:

Repeat steps 1-3 until the garage door reverses during closing.

Step 5:

When the garage door reverses and then stops in the fully open position, press the (+)

increase button 1 time. The Close Force is now set properly.

Make sure the garage door is in the fully Down/Closed position.

Press the wall button or the button on the remote programmed for this Guardian

Opener to open the garage door.

Step 3:

If the garage door opens fully without stopping, press the Open Force (-) decrease

button one time.

Step 4:

Repeat steps 1-3 until the garage door stops before it fully opens.

Step 5:

When the garage door stops before it fully opens, press the (+) increase button 1 time.

The open force is now set properly.

The Guardian 315 Core Series 1/2 Horse Power Garage Door Opener is compatible with the

Home Link system and can be programmed for Home Link, but it is not compatible with the

MyQ system and will not program to MyQ.

Based on my experience working with Guardian Operators, I would not recommend it for

several reasons. First it is not compatible with the MyQ system and after market replacement

remotes will not program to the Guardian Operators. You must use Guardian remotes. Second

is the fact that Guardian has had problems with the head units that control the function of the

openers and I had to replace many head units on the Guardian openers. Aside from these

items, the Guardians are fairly simple to install and program. Guardian operators seem to have

the power needed to effectively open and close garage doors without issue.
