Repairing Your Nice Robus Sliding Gate Motor
Today, I will guide you through the repair process for a Nice Robus sliding gate motor. Follow these steps to troubleshoot and fix common issues.
Step 1: Check Photocells
If the gate won’t close, first put it on manual mode. Move the gate to the middle and try closing and opening it. Check the photocells for visible damage caused by insects or water. If you find any suspicious signs, clean the photocells. If cleaning doesn’t help, replace them.
Step 2: Inspect Photocells Wiring
If the photocells appear fine but the gate still won’t close, check the photocells wiring. Look for any faulty wires and fix or replace them as necessary.
Step 3: Test Photocells Functionality
To further check the photocells, unplug the BUS plug. Turn the motor power off and on. Wait until the controller recognizes that there are no BUS devices. Try operating the motor. If it works fine, the issue likely lies with the disconnected photocells.
Step 4: Inspect the Controller
Check the controller for visible damage. Look for dried slugs or wet soil from ants. Replace the controller if you find any such damage.
Step 5: Dismount the Unit
If the photocells and controller are in good condition but the motor still malfunctions, delve deeper into the unit. You’ll need rust penetrating spray and a long Philips number 2 screwdriver. Dismounting the unit is tricky and should only be done if you are experienced. There is one screw under the grey cover and at least one behind the controller. Spray them with rust penetration spray and wait. Then, use the screwdriver to remove the screws. You will see the transformer after opening the enclosure.
Step 6: Check Transformer Power
Unscrew the transformer and check the power coming in and out. Ensure it’s functioning correctly.
Step 7: Test the Motor
Locate the blue and red wires going to the motor. Cut them in the middle and attach the motor wires to a 12vdc battery. If the motor runs, swap the polarity to make the gate move in the other direction.
Step 8: Inspect the Rectifier
Now, focus on the heart of the unit—the rectifier. It sits in a cavity where moisture accumulates, causing the rectifier legs to corrode and break over time. This is a common reason for motor issues but is often overlooked. If you find the rectifier in bad condition, replace it. I went to a DIY electric shop (Jaycar) and asked for the most powerful rectifier, which worked fine.
Step 9: Remove Stubborn Screws
Sometimes, if you don’t have the right screwdriver or the screws are stuck, you can gently cut them with a multitool or grinder. If you do this, drill a couple of holes and fit small screws to keep the enclosure tight in place.
