Opening/Closing the Barrier (Gate) Enclosure

Removing/Replacing the Top Cover

Note: Use caution not to damage or scratch the finish after removing the top cover.

To remove the Top Cover, insert the Magnetic Gate key into the horizontally oriented key slot. Turn the key counterclockwise to disengage the locking mechanism. If the key resists turning, sometimes using the bottom of your fist, and tapping on the top cover just above the key will help to get the lock to disengage. Once the lock disengages, pull the front of the Top Cover upward and then slide rearward to disengage the static rear L-locks.


To replace the Top Cover, engage the rear static L-locks into the slots, then making sure the keylock is in the unlocked (vertical) position, lower the cover onto the gate. JFK

Here is a picture of the barrier with the Top Cover removed:

Accessing The Inside of The Barrier (Gate) Enclosure

Note: Use caution not to damage or scratch the finish after removing the front panel.

Once the top cover has been removed, the inside of the enclosure may be accessed by removing the Front Slide Panel. To accomplish this, grab the Front Panels top edge and pull upwards. The Panel rides in slotted tracks on either side and may be completely removed by sliding the Panel upwards until it slides free of the tracks. Below are pictures of the Front Panel sliding open halfway and one of the panels removed completely.

To replace the Front Panel, align both edges with the tracks on the enclosure and then slide the Panel into the tracks and push downwards until the panel is in the full down position. The panel is captured by the Top Cover when it is in place, and once the keylock has been engaged it is inaccessible and prevented from being removed.

Turning the Barrier (Gate) Power On/Off

Start by accessing the inside portion of the gate enclosure by following the Top Cover and Front Panel removal procedures covered on pages 3 and 4. Once access to the inside of the enclosure is achieved, you will find the power switch on the lower right-hand side. See the pictures below.

Barrier (Gate) Controller Program Mode

While working with Flash support you may be asked to verify the Program Mode of the barrier (gate) controller. The Program Mode is an internal set of instruction or Program that tells the controller how we wish the gate to operate. We normally will run in Program Mode 5. To verify this, we look at the top left side of the gate controller.

If you see this “Wrench” symbol it indicates that the gate is in the service mode. More information on the 

Checking and Clearing Barrier (Gate) Controller Messages

Gate Controller Messages come in three formats:

Event messages - "INFO" Event messages inform us about events such as "switching to battery operation". The gate continues to run normally. Event messages do not influence the outputs of the control unit.


Warning messages - "WARNING" Faults that could be reset by the control unit are displayed as warnings. Operation of the gate is not or only briefly impaired. If the function "Warning" has been chosen for output, this output is deactivated at pending warnings (fail-safe).

Error messages - "ERROR" Faults that cannot be reset by the control unit are displayed as errors. The gate will be inoperable.

To view the messages, first, you must remove the gate's Top Cover as listed on page 3. Once the cover is removed you will have access to the barriers control unit. See the picture below. Also, refer to page 10 for precise button locations.

Accessing the Messages

To access the messages, begin by pressing the left most button on the controller, labeled with the Square.

Scroll through the message list by using the Up and Down Arrows.

The messages will contain a Date/Time Stamp and the actual message.

The messages could display Text, Numbers, or both. By supplying these messages to the Flash Support Technician, it often assists them with troubleshooting current or past barrier problems.

Clearing the Messages

  1. Press the left most button, labeled with a square.
  2. Using the up/down arrow keys, select the message to be cleared.
  3. Press the right most button, labeled with a circle to clear.
  4. Select the next message to be cleared using the arrow keys or continue to press the circle button to clear the highlighted error message.

Resetting the Barrier (Gate)

The Control unit reset is performed in one of two ways:

  1. Switch of the power as described on page 5 and switch it on again after 10 seconds.
  2. Press the two middle operating buttons (Arrow Up and Down) on the control unit display for 5 seconds.

Service Mode

In the "Service" mode, all opening and closing signals are ignored. The functions of safety devices like the safety loop or safety light barrier remain active for security reasons. This means that as soon as the safety loop is occupied, the barrier cannot be closed. Reference the picture below showing the location of the Service Switch. The switch position shown in the picture is in the Normal Run Mode and the LED will illuminate Green. To select the Service Mode, slide the switch lever towards the rear of the controller. When the Service Mode is selected The LED illuminates Red. The display backlighting flashes and will display an “X” symbol in place of the Program Mode number.

Raising and Lowering the Barrier (Gate) Arm ManuallyA screenshot of a computer

Description automatically generated with low confidence

To Raise or Lower the gate arm manually we use the gates controllers “Service Mode” To access the Service Mode we need to manually slide the selector switch to the Service Mode position. See the picture for the Service Mode Selector Switch location. (reference Service Mode above)

The Normal Run Mode is indicated by switch being in the forward position as shown in the picture to the right. The LED will show Green.

Service Mode is selected by sliding the switch to the rearward position. Once selected, the small LED next to the switch will illuminate Red indicating that the Service Mode is in effect.

Returning the selector switch to the forward position will cancel the Service Mode. The LED will illuminate Green, and the gate will resume normal operation.

Once the gate is in the Service Mode:

Note: Use Caution as the Barrier (Gate) Arm will move as soon as the appropriate control button is pressed and move to the full opposite position. Make sure there is nothing restricting the arm from moving full range in either direction prior to manually moving the boom.

  1. The Gate Arm may be raised by pressing the UP Arrow control button located just below the display.
  2. The Gate Arm may be lowered by pressing the DOWN Arrow control button located just below the display.

Note: Be sure to place the Barrier (Gate) back into the Normal Run Mode when work is completed. If the barrier (gate) is left in the Service Mode, the gate will not function as expected.

Closing or Opening the Barrier (Gate) Arm in Case of Power Failure

In case of power failure, the gate arm may be in the lower (arm down) or upper (arm open) dead point, I.E; the gate arm can no longer be easily moved manually. In this case, proceed as follows: 

  1. Remove the gate housing hood. Refer to page 3
  2. Remove the gate housing door. Refer to page 4
  3. Press a tool (screwdriver or similar appropriate tool) straight into the appropriate tool bore hole. The lever arm is pressed from the dead point. See picture on below for reference.

    Use the Upper tool bore for opening the barrier.
    Use the Lower tool bore for closing the barrier.

Note: This process will not work with the gate's power in the ON position.

  8. Press right control button. (circle)
  9. The safety prompt "Save changes?" appears.
    If the changes are to be saved, press the right button. (circle) The current settings are
    reset to factory settings. A restart is performed.
    If the changes are not to be saved, press the left button. (square)
  10. Press the left button (square) repeatedly until the operating view is displayed again.

Understanding the Loop Indicators

By looking at the barrier (gate) controller display we can determine the status of the connected loops. In most instances there are two (2) loops connected to the gate controller, the Safety (A) Loop and the Arming (B) Loop. In some installations there may be two (2) additional loops, which will be designated as “C” and “D”. This picture shows the A and B Loops connected properly. The A and B icons are displayed and Not Flashing. If the icon is Flashing that indicates that the loop is occupied and most likely there is a vehicle sitting on top of it. One loop may be active, or in some instances both may be active simultaneously.

Here is a list of the Induction Loop Symbols you may see and their meanings:

Not Flashing - Indicates that loop A and B are both connected.
Flashing - Indicates that the loop is Active.
Indicates that a Reference has been performed.
Indicates that the Induction Loop is Deactivated or Not Connected.
Indicates that the Induction Loop is Defective.

Recalibrating the Loops

There may be instances where one or more loops in a lane need to be Recalibrated. The easiest and first thing to try is powering off the barrier (gate). First the loops need to be clear so make sure there are no vehicles or metal on the loop. Refer to the procedure on pages 3 and 4 to gain access to the gate enclosure and page 5 for instructions on how to turn off the power. Once you turn the gate Off, wait at least 10 seconds and then turn the power back On. While powering up, the gate will attempt to Recalibrate all loops connected to the controller. Once the gate is back in normal operation, test the loops to insure they are functioning properly.

If that doesn’t correct the loop issue, we can try Recalibrating the troublesome loop by using this procedure:

  1. Always verify that there are no vehicles or other movable metal objects near the loops before recalibrating.
    (Reference the picture at right for button locations)
  2. Under the Digital Display there are 4 buttons. Pressing the 4th button (circle) once will take you to the main menu. (picture 1 below)
  3. Use the middle two buttons (up and down arrows) to navigate to Detector 1 (A-B) and use the 4th button (circle) to enter the selection. (picture 2 below)
  4. The top item inside this menu will be “Recalibrate”. Use the 4th button (circle) to select it and wait a few seconds while the gate recalibrates. (picture 3 and 4 below)
  5. One the recalibration is completed use the 1st button (square) a couple times to return to the normal operating screen. Test the loops to verify that they are functioning properly and detecting metal/vehicles.

Understanding the Input/Output Indicators

Understanding the controller’s input and output indications may help in troubleshooting various problems. The field wiring input signals to the barrier (gate), the Relay Outputs, and the Digital Outputs each have a Green LED indicator that illuminates when that signal is Active. If the LED indicator is Off, that indicates the signal is Inactive See the picture below:

In this picture you can see the various indicator next to each of the labeled inputs and outputs. Each LED indicator is also labeled with a number that corresponds to the input or output that it is associated with. The picture above is showing that DO3 and Relay Output 5 are Active (green LED). Everything else is Inactive.

NO1 through C4-6 Analog Relay Outputs

Resetting/Adjusting the Barrier (Gate) Arm Position

The barrier (Gate) arm may get pushed or bumped and cause it to be out of position, and no longer level with the drive lane. Providing the gate arm is not damaged it is relatively easy to realign. You will need a #10 Hexagon (Allen) Wrench.

  1. Start by locating the 4 #10 Allen Head Bolts that clamp the main gate arm fitting to the gates rotating shaft. They may have Gray colored plastic caps installed. If so, remove the caps by lightly prying them out with a flat blade screwdriver. (refer to pictures below)
  2. Place the gate in the Service Mode. Refer to page 7.
  3. Place the gate mechanism in the desired arm position, Fully Up or Fully Down, by pressing the appropriate control button. Refer to page 7.
  4. Once the gate arm position has been selected, power off the gate. Refer to page 5.
  5. Using a #10 Allen Head Wrench, slightly loosen all four of the clamping bolts located in step 1.

Warning: Only slightly loosen the clamping bolts and only a little at a time. Loosening them to much could cause the gate arm to fall and could cause injury. Loosen them slowly until the gate arm can be rotated on the shaft, but not so loose that it falls free.

  1. Move the gate arm position until it is Level to the lane surface, or Vertically 90 degrees to the lane surface, depending on the position you selected in step 3. Check with a carpenter’s level if desired. 
  2. Once the desired position is obtained, retighten the 4 #10 bolts using the Allen Head Wrench. Use a rotating patten to tighten the 4 bolts. They need to be tight to prevent the gate arm from becoming misaligned again. If you have a Torque Wrench available, the bolts should be final torqued to 55.4-foot pounds.
  3. Once the bolts have been tightened, turn the gate back on. 
  4. Run the gate arm up and down in the service mode to check that the correct position has been achieved and that the arm moves through its full rage.
  5. If the arm still needs adjustment, repeat steps 1 through 7.
  6. Once satisfied with the gate arm alignment, place the arm in the down position while in the service mode. Turn the gate power Off.
  7. Move the Service Switch back to the Normal Run Position.
  8. Wait at least 10 seconds and they turn the gate power back to On.
  9. Place the gate back into the normal run mode and verify the gate arm alignment and movement by performing a live test transaction.
