Mecer 1200va not opening garage door

Recommended Posts

Hi guys I have a a mecer 1200va connected with to a Vision 100ah. 

My garage door only open a fraction when disconnected from mains supply. 

Door opens normally once mains is back.

Couldn't get any specs for the motor anywhere.

Check battery voltage whilst opening garage door and power is off.

Also check torsion spring adjustment: Disconnect door from door operator motor and manually open door half way. The door must not close or open from this position on its own. If manually closed a bit it should then close completely by its own weight. Similarly if opened a bit it should open fully by the torsion springs tension.

I had one of those... but it broke way back in December 2012. This is what the big worm gear mechanism looked like:

These door openers have a normal 230VAC induction motor, and as a result it will have somewhat of a start spike, generally about 5 times its nominal rating. I suspect that's the issue, it simply overloads the inverter.

I have since thrown the remains of it away, but a it of googling indicates it has a 0.5 horsepower motor, which is just short of 400W. That would need a good 2kw kick when it starts. While many inverters (including the voltronics) can handle a 200% spike for about a second, I suspect your's is JUST a tad outdone by that motor.

A new low-voltage motor is around 2.5k and well worth it imho.

Thanks guys. 

Yes seems like OVERLOAD. See attached Troubleshooting from the manual. 

Shall I try my 24v Mecer 2400va?

This is a sectional door operator, right?

If so then: Check torsion spring adjustment: Disconnect door from door operator motor and manually open door half way. The door must not close or open from this position on its own. If manually closed a bit it should then close completely by its own weight. Similarly if opened a bit it should open fully by the torsion springs tension.
