Answers You Need for Turntables, Parking Sliders & Lifting Platforms

Welcome to the Carousel USA Frequently Asked Questions page — your resource for expert answers about turntable systems, parking sliders, lifting platforms, installation requirements, electrical setup, troubleshooting, and custom options for residential and commercial applications. All answers come straight from our engineering and technical support teams to help you get the most out of your equipment.

Electrical Power & Control FAQs

Most control panels use single-phase 220 VAC power, typically 15 Full Load Amps. Controllers compatible with 120 VAC are available. For large Commercial Turntables, 480 VAC is preferred. 

What output power goes to the motor?

Standard output to the motor is 220 VAC, three-phase with a full-load current of about 4.2 A

How many conduits are needed for an MC3 controller?

We recommend two ¾″ conduits to the motor pit — one for motor power and one for encoder signals — sized to comply with your local electrical codes. 

How far can I mount the control panel from the turntable?

For reliable operation, mount the control panel within 50 ft of the turntable whenever possible. 

Can the control panel be installed outdoors?

Standard controllers are for indoor use, but weather-proof outdoor options are available upon request. 

What is the remote-control range?

Typical wireless remotes operate up to 100 ft line-of-sight. Extended-range remotes are available. 

How many conductors do I need to run from my control panel to the motor?

For a Standard Control Panel you will need 4 conductors from your control panel to the motor. 3 hot wires and 1 ground wire. For a MC3 Control Panel, you will need a total of 8 conductors, 4 for the motor power and 4 for the encoder signal.

Mechanical & Installation FAQs

Yes! We design custom configurations and modifications to meet unique space, weight, and use-case requirements. 

What does “dead load” vs “live load” mean?

  • Dead load — the static weight of the equipment itself.
  • Live load — the weight of the equipment plus the payload (e.g., vehicle weight). 

How should floor flatness be measured for surface mount turntables?

Use the guidelines in our installation site flatness documents for accurate measurement.

40SSV INSTALLATION SITE FLATNESS 

or

55SSV INSTALLATION SITE FLATNESS

What pit depth is required for flush mount turntables?

Standard steel, aluminum, or wood-topped turntables need 12.75″ pit depth; concrete-topped turntables require 20″, with some models at 15″

 

What is the maximum slope for flush mounted in-ground turntables?

Up to 8% slope is allowed when the pit bottom is parallel to the top edge surface

What’s the typical installation process?

  1. Pour pit floor and curb
  2. Install turntable
  3. Install trim ring
  4. Apply grout pack mortar
  5. Pour final concrete

Troubleshooting Turning, Control & Power Issues

Why won’t the control panel door close?

Ensure both power disconnect and interlock switches are OFF, check for mechanical interference, then close and lock the door fully before powering on.

Warning: opening the control box exposes live wiring. any work performed inside the control box is done at the user’s own risk. to prevent electrical shock use caution whenever working near exposed wiring or connections.

Turntable won’t rotate — what now?
  1. Verify the green power light is on.
  2. If not, check breakers and reset if needed.
  3. Try rotation again using the remote or control panel. 
What if the red “Fault” light is on?

This indicates an active VFD fault. Try clearing the code temporarily or check for debris binding the turntable — even small debris can stop movement and trigger faults. 

Remote control not working?

Often this is due to weak or dead batteries. Check the remote’s indicator light and replace batteries if needed. 

If problems continue, contact Carousel USA support. Factory-trained technicians can assist by phone or onsite if required.

Control Systems & Documentation

We offer several control system options depending on your needs:

 

Each control type has downloadable Documentation and Troubleshooting Guides available on the site.
