A gate that opens and closes manually but ignores FlexWash is not a hardware fault. The barrier, motor, and boom are proven working. The problem is upstream: programming mode, a conflicting input, or the network. Work through this in order. Each step rules out everything before it.

Step 1. Check for power

Remove the top lid of the gate and look at the screen. A dark screen means the gate is turned off or has no power. Check the power switch before going further. See Magnetic Gates for the mains switch location. If the screen is on, continue.

Step 2. Test the gate manually

Open and close the barrier by hand in service mode. See Magnetic Gates for the service mode procedure.
If the barrier moves manually, the motor and boom are fine and the fault is upstream. If it does not move, stop here. That is a hardware problem, not a configuration problem.

Step 3. Check the programming mode

The left side of the screen should show the number 7. Any other number means the gate is in the wrong programming mode and will not accept commands from FlexWash. To set it:
1

Open the main menu

Press the circle button below the screen.
2

Select Function

3

Set the programming mode to 7

Then press the circle button again to save.

Step 4. Clear conflicting inputs

An input set to Ext opening loop exit breaks programming mode 7. The mode can read 7 and the gate will still fail. Any input with that value must be cleared to -.
To check the inputs:
1

Open the main menu

Press the circle button below the screen.
2

Select In-/Outputs

Go through each input and check its value.

Step 5. Reseat the ethernet cable

Check the screen for an error icon . If one is present:
1

Turn the gate off

Power it down before touching the cabling.
2

Reseat the ethernet cable at the gate

Unplug it and plug it back in, confirming it seats fully.
3

Check the other end

Confirm the cable is seated on the FlexWash switch inside the office.
4

Turn the gate back on

Then retry a command from FlexWash.

Other gate symptoms

Gate stuck open (Open High Priority)

The gate will not respond to open or close commands. Usually the key switch.

Gate opens randomly (Queue Out of Sync)

The gate cycles open with no car present and the queue backs up.
