How to adjust open close limits on a 4 meter gate for a Germin motor

The latching delay is an important safety feature on an Elite gate opener, and it is not recommended to defeat it. The purpose of the delay is to ensure that the gate is fully closed and in the correct position before the magnet engages to latch the gate. Disabling the delay could cause the gate to not close properly, which could be a safety hazard and may also damage the gate and the gate opener.
If the magnet is not grabbing the gate on the first impact, there could be several reasons for this. One possible cause is that the magnet is not properly positioned, which could cause it to miss the gate on the first impact. In this case, adjusting the magnet's position may help.
Another possible cause is that the gate is not aligned properly, which could prevent the magnet from making contact with the gate on the first impact. In this case, adjusting the gate's alignment may help.
It is recommended to refer to the owner's manual for your Elite gate opener to learn more about the proper position and alignment of the magnet and the gate.

Sounds like the travel limit switches are out of adjustment

most sliding gates suffer form dirt, grass , rocks in the gate track so constant cleaning of that track is essential
small twigs , rocks will slide along with the wheels on opening but are an obstruction for the wheels on closing
most closing gates run a cog and rack system at the bottom ot the gate so check that the mesh of the rack and cog is correct at either end

There are switches on both ends of the course of the motor, if one fails it will only work on the side that´s ok. That´s why it opens but do not close.Check it out.

Check with a multi-meter that the switch itself has a open/closed function(ohm meter setting)Hope this helps....

Check if it has stops anywhere in the system, usually there are micro switches that are activated by arms, etc that tell it how far to open and close. You may need to adjust them.

Your manual override is active. This disengages the gearbox from running the gate. You will need to release the manual override. What make and model gate motor is it?

Do you know how to test automotive electrical circuit's with a DVOM - digital volt ohm meter ? When adjusting the moon roof did you see any switches ? sunroof limit switch
Measure the reference voltage of the sunroof limit switch soft stop signal circuit at the sunroof control harness connector to a good ground.
Does the reference voltage measure near the specified value?
4.5-5.5 V
Notice: Do not open the sunroof glass past the full open soft stop position. Doing so may damage the sunroof assembly and or the roof top.
Connect a jumper wire to the sunroof limit switch soft stop signal circuit at the sunroof control module harness to a good ground.
Turn ON the ignition, with the engine OFF.
Using the sunroof switch, operate the sunroof system, not to exceed the full open soft stop position.
Does the system operate as requested?

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof motor with the limit switches
• Sunroof switch
• Sunroof glass-spoiler type, with glass sliding above roof
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power sunroof system circuit breaker: PWR WDO 25 A
• Ground: G204

Sunroof Limit Switches
The sunroof limit switches track the position of the sunroof glass through two limit switches:
• Soft Stop limit switch through the sunroof limit switch soft stop signal circuit
• Vent Stop limit switch through the sunroof limit switch range signal circuit
The sunroof control module monitors the limit switches and based on the input combinations, determines the position of the sunroof glass. As a sunroof limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling the 5 volt reference to 0 volts.
The sunroof control module monitors both sunroof switch input requests and based on the sunroof limit switch input combinations, will control an output to the sunroof motor, to drive the sunroof glass to the requested position.

Sunroof Motor
The sunroof has a bi-directional motor. When the motor is not operating both circuits are grounded. When the motor drives the sunroof glass in the direction from the closed to vent or vent to open position, the following occurs:
• Voltage is supplied to the sunroof motor open circuit.
• Ground is maintained to the sunroof motor close circuit.
When the motor drives the sunroof in the direction from the open to vent or vent to closed position, the following occurs:
• Voltage is supplied to the sunroof motor close circuit.
• Ground is maintained to the sunroof motor open circuit.
The sunroof control module is equipped with a timer circuit which stops the operation of the sunroof motor after 8 seconds.

Hello and welcome the problem is very simple to resolve first make sure you have battery power turn off vehicle open rear gate unlock doors go to rear gate and look at lock unlock again and push the Grey plastic lock trigger mechanism forward towards front glass close gate unlock again make sure lock is still in the position you just set it to and close glass it will the lock. Normally what happens in this situation was power was removed from your jeep and the rear gate was opened with no power running to electric lock so it stays in a set position you cannot lock the glass because there was no power in the electric lock I will lock once you reset it Hope this help.
