White Wire - AI

Once routed into the Control Panel, the unused/excess wire can be Cut off, or Coiled up inside the Panel

AT THIS POINT, THE MOTOR AND CONTROL PANEL ARE WIRED COMPLETELY. YOU ARE READY TO TURN ON THE POWER, BUT PLEASE BE AWARE OF THE RISK INVOLVED WITH AC POWER, AND TAKE CARE WHEN WORKING ON YOUR GOFF'S DOOR WHILE THE POWER IS ON.

The "Home" Tab will Include the Primary OPEN, CLOSE, and STOP Buttons.

It will also Show the Count-Down Timer Should you Turn on "TIME TO CLOSE MODE".

Asterisks will be Replaced with Numerical Value Designating How Much Time (in Seconds) is Left Before the Door Automatically Closes.

When "TIME TO CLOSE MODE" is Disabled, the Goff's Logo will Appear.

Press the "Setup" Tab.

Notice a New Tab Appears Titled "Limits". Ignore This Tab for now, But This is Where the Limits will be Set Later on.

The "Setup" Tab is Where You can Enable/Disable "TIME TO CLOSE MODE", And Toggle Between "SEQUENTIAL" And "NORMAL" Door Operation Modes.

Setup Tab is Discussed in Greater Detail in Following Steps.

If you Wish to Setup "TIME TO CLOSE MODE":

Navigate to the "Setup" Tab.

Press the Numerical Value Field, and Assign the Value Corresponding to the Number of Seconds before you Want the Door to Automatically Close.

This Process will Enable "TIME TO CLOSE MODE" And will Assign your Value to the Timer.

To Change the "DOOR OPERATION MODE":

Navigate to the "Setup" Tab.

Press the Button Corresponding to the Desired Mode of Operation:

The Door will come Configured in "NORMAL" Mode, which means the OPEN, CLOSE, and STOP Buttons Function as Their Name Implies.

"SEQUENTIAL" Mode makes it so that you can Utilize Single-Button Remotes/Button Stations or Pull-Cords to OPEN, STOP, and CLOSE the Door.

"SEQUENTIAL" Mode makes it so that the OPEN Button on the Touch Screen Home Tab Functions as all Commands through the OPEN, STOP, and CLOSE Sequence.

The CLOSE and STOP Buttons will still Only CLOSE and/or STOP the Door, Respectively.

To Set the OPEN and CLOSE Limits:

Navigate to the "Setup" Tab.

Notice a New Tab Appears Titled "Limits".

Navigate to the "Limits" Tab.

A Keypad Will Appear, at Which Point you Must Enter the Password "limits" (all lowercase) to access the Limit-Setting Screen.

The OPEN and CLOSE Buttons (ON THIS SCREEN ONLY) are Constant Pressure. They will Operate the Door as long as they are Held. Once Released, the Door will Stop.

The STOP Button will Stop the Door when it is pressed (Momentary Pressure).

On the Encoder unit flip-open the blue cover, exposing its (3) setting buttons. PRESS THE RED "R" BUTTON TWICE QUICKLY TO ENTER TEACH MODE. The green LED on the encoder will flash and then stay on, indicating that it is in teach mode.

Back on the Control Panel Touch Screen, Tap the "TEACH ENCODER LIMITS" Button.

Using the CLOSE button on the touch screen, jog the door down by HOLDING the CLOSE button until you have moved the door into the desired closed position.

Once at the desired closed position... on the encoder unit, press the green button labeled "0%". The LED on the encoder will flash again and then stay on, indicating that you have saved the closed limit setting.

Jog the door up by HOLDING the OPEN button on the touch screen until the door has reached the desired open position. Go back up to the encoder and press the green button labeled "100%". Again, the LED on the encoder will flash and then stay lit, indicating that it has saved the open limit setting.

Back to the touch screen again, press the "JOG TO TOP TAP TO SET" button to teach the open limit to the controller. The open limit is now saved in the encoder and taught to the control panel.

Now that both limits are set and taught, go up on the encoder and PRESS THE RED "R" BUTTON TWICE TO EXIT TEACH MODE. The LED will flash and then turn off to indicate that the encoder is out of its teach mode and ready to run.

Run a Test Cycle to see Where the Limits Stopping the Door.

The Limits May Need to be Re-Taught if they are Significantly Off From Where they Need to be. Repeat the Process in the Previous Step to do so.

If the Limits are Off by a Small Margin, you can use the Top and Bottom Offset Settings to Make Minor Adjustments.

Think of How the Brakes are Applied in Your Car as You Approach a Stop Sign:

The Offsets Represent How Early (or Late) You Begin to Apply the Brakes to Ensure You are Completely Stopped when you Reach the Stop Sign. The Stop Sign is the Limit Position we Previously Taught.

If the Door is Over-Traveling Past the Taught Open or Closed Limit, Increase the Value of the Corresponding Offset to Make the Door Begin to Slow Down Sooner.

If the Door is Under-Traveling, and Coming up Short of the Taught Open or Closed Limit, Decrease the Value of the Corresponding Offset to Make the Door Begin to Slow Down Later.

To Adjust the Offsets, Press The Numerical Value in the Corresponding Field, and Adjust as Necessary.
