Product Q&A
4 QuestionsQ: Zone damper with ma-nd4 ewc control. The motor turns the shaft but does not open or close the damper. How do I replace the shaft that is stripped or broken?
Asked by none 11 years ago

No luck here - you have to replace the whole motor. They do not sell individual parts for motors.
Q: How long does it take this damper to go from full closed to full open?
Asked by Rick Macy 13 years ago

Damper's motor MA-ND5, which is a standard motor for this type of dampers, makes full open or close cycle (90 degrees) for 35 seconds. The time is independent from load. For more specifications of the motor see attached file.
Q: From the picture it looks like the dimensions are 8" Height X 16" Wide and the motor is mounted on the 8" dimension. Is that correct?
Asked by Hank 13 years ago

No. Here is a quote from the manufacturer: The motor will be mounted on the second dimension when ordered. In your case, it is 16". The picture is a generic image for all dampers regardless of size and orientation.
On website it's how you order it dimension wise. From the picture it looks 8"h by 16"w with motor on 8" side. If you order 16"h by 8"w it's on 16" side. It says somewhere on there. -----Original Message-----
The motor is always mounted to the second dimension specified. This picture is not accurate but the description is and it states that the motor is mounted to the second dimension side so it's on the 16" side.
I'm just a home owner and its been a while since I ordered but from what I can remember, the motor is mounted on the side of the first number. So 8x16 would be on the 8" side. 16x8 would be on the 16" side. Hope that helps.
No. Motor is on the bottom. If you click on the Overview tab on the product page... http://www.pexsupply.com/EWC-8X16ND-8-x-16-ND-Motorized-Damper Motor Mount: Bottom
Yes, that is correct. The motor is on the 8" side of the unit. This product worked great for me.
According to the manufacturer that is a 16" X 8" motor is always mounted on the 2nd dimension a 8" X 16" will have the motor installed on the 16" side.
Q: is the damper powered open or powered closed?

This damper requires power to open and power to close. It will not move without power in any direction. The motor has three terminals: common wire, to open, to close. The damper operates 24 VAC.
It is powered open and closed. Sent from my iPhone
It is not 'sprung' and needs power to achieve either state. Sent from my Verizon Wireless 4G LTE DROID
This damper is both powered to open and powered to close.
It looks to be powered open and powered closed.
The damper is powered in both directions and the motor only runs until the desired position (open or close) is reached. The motor comes with 3-wire connections : neutral, open (power) and close(power)
