7. What safety features do SVS Lifts have?

• Redundant limit switches (two up/two down) for safe and secure motor shutdown.

• USA patented drum lock systems to ensure safety in event of a mechanical failure (100% safety record after 20 years of manufacturing).

• The projector weight is suspended by two 3/16-inch steel cables capable of supporting 1780 lbs [807kg] each.

• The use of channel scissors, heavy steel, grade 5 fasteners and other heavy duty components, combined with the precision grooved drum and other manufacturing techniques ensure safe level, accurate tracking with properly mounted equipment at lowering distances to 33-feet.

(dimensions do not include projector or other accessories which may increase the minimum ceiling opening size. Please contact SVS  for the exact ceiling opening for your application.)

10. Can I use an Accessory #12 Decorative Cover with a SVS Mini 4 2X2 or M2X Series Lift?

Sorry but we have not been able to design a Decorative Cover that will work with a 2X2 ceiling opening. The Accessory #12 Decorative Cover is not offered with the SVS M2X or Mini 4 2X2 Series Lifts.

11. What is the different between the SVS Mini 4 2X2 Lift Series and the Mini 4 Standard Lift Series?

The Mini 4 2X2 Lift Series is designed to be used with 2X2 ceiling grids. The Mini 4 2X2 Lift Series is normally sold as a package including the Mini 4 Series Lift, Accessory #16 Compact Cable Management, and a M4#1A 2X2 Ceiling Closure. The M4#1A Ceiling Closure comes in two sizes to accomodate 9/16" or 15/16" ceiling grids. The 2X2 ceiling grid limits the size of the projectors that can be used with the Mini 4 2X2 Lift Series.

The Mini 4 Standard Lift Series can be used with the Accessory #1 or FP1 Ceiling Closures. The Accessory #1 and FP1 Ceiling Closures allow larger projectors to be used with the Mini 4 Standard Series.

12. What is the normal leadtime for a SVS Lift?

All SVS Lifts are built-to-order. The normal leadtime for SVS Lifts is two weeks. Large or custom orders may require longer leadtimes. Rarely will the leadtime be longer than three weeks.

13. What SVS Lift can I used with a 2X2 ceiling grid?

You can use either the SVS M2X or Mini 4 2X2 Series Lifts with 2X2 ceiling grids.

14. How do I connect my SVS Lift to an external controller?

SVS Lifts are control with 24vac contact closure. Two methods to contect to an external controller are Option 1 and Option 2.

Option 1: Lift is controlled by the external controller. The Wall Plate Control Key Switch selects the whether external controller will lower the lift to the Show or Service positions.

Option 2: When the Wall Plate Controller Key switch is in the Show position, the external controller controls the lift lowering to the Show position or raising the lift to the ceiling. When the Key Switch is in the Service position the Wall Plate Controller Up/Down Toggle switch lowers the lift to the Service position or raises the lift to the ceiling.

At the wall plate control terminal strip the control wires are:

• White wire is the common (24VAC supplied by the lift)
• Red wire is the up
• Brown wire is down to Service
• Green wire is down to Service
• Orange wire is the Motor LED positive
• Black wire is the Motor LED negative
  

The lift is lowered to the Show position by connecting the white wire to the brown wire
The lift is lowered to the Service position by connecting the white wire to the greem wire
The lift is raised by connecting the white wire to the red wire

POSITIONING

Using the Key Switch Controller, lower the lift (with Key Switch in Service position) to where your Show position. The Show microswitch is adjusted by loosening the thumb screw on the Show microswitch bracket, located on the lifts top frame. Position the bracket along the roller guide so that the microswitch touches the large retainer washer. You should be able to see or hear the microswitch on the bracket compress and make contact. Make sure the microswitch is not positioned too close to the washer because the washer must pass under the microswitch when going to the Service position.

OPERATION OF SHOW POSITION

• The key switch controller operation for the Show position operates by switching the key switch to Show and pressing the toggle switch down. When the lift reaches the Show microswitch, it will stop.
• To lower to the Service position, switch the key switch to the Service position and press the toggle switch down. The lift will lower to its maximum drop length, until the down limit microswitch stops the motor.
• Pressing the toggle switch up works in both the Service and Show position on the key switch. The lift will not stop at the Show position when using pressing the toggle switch up.
