1200W Industrial Air Blower Not Working on First Use

2 months ago
#416 Quote
Hello, everyone! I have an ATO-ABL-1200 (WB3-1I-H) 1200W industrial air blower, and I plugged it in today for the first time, but nothing is happening.
I connected the motor according to the instructions, with an e-stop between the mains and the blower.
I know the issue isn’t with the cable or the e-stop, as I triple checked everything.
I ordered the model with the internal potentiometer, and I tried various positions, but nothing happened.
Should the potentiometer have hard stops for the minimum and maximum positions? The potentiometer on my unit turns freely.
Any help would be greatly appreciated—thank you in advance!

Hi Beckett,
Thanks for the update. The input power of your industrial air blower is 110V, which is connected to the L and N terminals. There is a small hole next to the terminal block to display a potentiometer. You could use a screwdriver to adjust the potentiometer clockwise to turn it up (counterclockwise is to turn it down) and check whether the blower is working. Please refer to the user manual, see on: https://www.ato.com/Content/doc/adjustable-speed-air-blower-user-manual.pdf
If the blower still fails to start normally, please provide us with the position of the DIP switch as shown in the attachment, so we can check whether the DIP switch is set correctly. Please see attached.

Hi,
The dip switch is in position A, same as in your photo.
Regarding the potentiometer, is it normal for it not to have hard limits? i.e. I can turn the knob seemingly forever in each direction.
I deleted the e-switch this morning to see if that could somehow be the cause, but the blower still won’t power up.
I also tried a different circuit, but got the same result.
When I plug the motor, there’s no noise or heat, or anything at all coming out of the motor.
I confirmed there is continuity between the casing of the blower and the ground prong of my cable. I assume the other connections are also good.

Hi Beckett,
Pls set the dip switch to position C and test again.
There is a small hole next to the terminal block to display a potentiometer. You could use a screwdriver to adjust the potentiometer clockwise to turn it up (counterclockwise is to turn it down), as we mentioned before.

Ah! It works now.
Thank you!
