AUTOMATIC GATES AND ITS COMMON FAILURES

usual failures in automatic gates

So many year around gates, automatism and surveillance system. After this time, Powermatic has resolved a lot of problems, someone more dificult than others.

In this article, we´re going to show you the commonest failures in automatic gates and how to proceed with them. Remember that a qualified technician could help you to assure the correct working of your gate.

Sliding Gates Failures.

Motor doesn´t work: if we see that our gate´s motor doesn´t work, first of all we´ll confirm the power supplier. We´ll check if there are blown fuse or the wires are out of their terminals. Don´t forget to check that security contacts are shor-circuited, emitter is programmed and has frecuency.

Gate is closed and we can´t unblock:  we have to look that limit switches are working correctly and if  the gate stop without we need to press it.

Gate doesn´t open and close completely: in this case, we have to check the manoeuvre timing of the gate. We´ll need more seconds that really required. So, we´ll look that limit switches are installed correctly. Don´t forget take attention, during the movement, the limit switch.

If we block the light of photocell and the gate stops and closes: we have to change the opening and closing wires, and the limit switches.

Motor sound but the gate doesn´t open and close: first of all we have to unblock the gate and move it until the middle. Push and test that opening and closing are correct, and the limit switch. We have to regulate the mecanic, electronic clutch and force.

Gate stops at the middle of movement: if motor stops to work, we have to increase the work time.  If the gate stops but motor still works,  we have to regulate the force (mecanic or electronic) and chech there isn´t any obstacle.

Swing Gates Failures.

Motor/motors don´t work: we have to check the power supplier. We´ll ckeck if there are a blown fuses or the wires are out of their terminals. We´ll ckech that the security contacts are short-circuited and emitter is programmed and it has frecuency.

One engine opens and other closes: change the opening and closing wires from motor. To know what it´s correct, we´ll have to see the leds or wait to automatic closing.

If we block the light of photocell and the gate stops and closes: we have to change the opening and closing wires, and the limit switches.

Gates don´t close: we have to check that photocells are connected correctly. Also, we´ll check they are aligned and the signal arrives to control pannel.

Gates stop at the middle of movement: we´ll have to regulate the work time, at leat, two or three seconds beyond the required time to do the complete movement.

Gates don´t open and close completely: we´ll check the regulation of hydraulic and/or electronic force. We´ll verify if there aren´t friction points during the gate movement. Don´t forget to check the installation levels that are fixed correctly.

Swivelling Gates Failures

Gate doesn´t work: first of all we´ll check the power supplier. So, we´ll check the blown fuses or if the wires are out of their terminals. Also, we´ll verify if the emitter is programmed and send frecuency. Finally, we´ll check if the security contacts are short-circuited.

Motor stop when gate is down and come up again: we´ll have to regulate the engine force, and the gate hasn´t any obstacle. At last, we´ll check the limit swicthes.

To open and close, the motor still works: we´ll have to regulate the limit switches.

Gate doesn´t close: we´ll check the photocells are connected, aligned and the pannel control receives the signal.

Gate closes by fits and starts: we´ll ckeck if the gate is balanced, and we´ll add extra weight if it´s necessary.

Motor sounds but gate doesn´t open: we´ll have to check  if gate is balanced and we´ll add extra weight if it´s necessary.

Barriers Failures.

Barrier doesn´t work: first of all we´ll check the power supplier. So, we´ll check the blown fuses or if the wires are out of their terminals. Also, we´ll verify if the emitter is programmed and send frecuency. Finally, we´ll check if the security contacts are short-circuited.

Barrier doesn´t open: we´ll veriry the spring, motor conections and limit swicthes.

Barrier doesn´t close: we´ll check if photocells are connected correctly, aligned and the signal arrives to central pannel.

Barrier opens and closes by fits and starts: we´ll have to regulate the spring.
