Stay Safe

Connect Limit and Safety Bumper Cables

Connect Cables at Cable Chain Bracket. Match the labels.

Connect the cables to the Forward and Forward Ultimate Limits.

Reverse and Reverse Ultimate Limits should already be wired in.

Connect Safety Bumper to Safety Interlock Pro

Connect the 3 pin XLR Safety Interlock cables from floorpocket bumper switches to REV Sensor In and Out on the Safety Interlock Box.

We reccomend that you add a halo set of bumper switches under your stage to protect a pinch point

Check limits

Run the Carriage all the way up and all the way down. Use a buddy to make sure you do not slam the carriage or platform at the ends of travel

Adjust as the limits as needed by loosening the screw and sliding the limis along the extrusion.

There is a standoff on the inside of the carriage that will strike the limit switch rod

Load Cell Configuration

Each Floorpocket should arrive to you with the Load Cell preconfigured with a label on the J-Box to enter into Spikemark for the Load Scaling Factor and the Load Offset Factor.

If you find that the scaling is different, first check the chain tension. You will want this to be looser than you expect.

Important Note: The Chain Tension will determine how much additional load is being applied to the motor and affect the amount of load the load cell is reading. It is reccomended that you run the platform all the way up, and then adjust the chain tension so that the chain is loose. About 3-4" of deflection measured from the center of the mast is about right, but you may need to adjust slightly to get accurate load readings.

Make sure the chain gaurds are installed so that the chain cannot be disengaged from the lower drive sprockets.

If you have the chain very loose, and the scaling is off, use the load cell configuration wizard in Spikemark to find the appropriate load scale for the Floorpocket.

INTERLOCK AUXILIARY LIMIT SWITCHES

Auxiliary Limits – These limits are wired in series with their corresponding standard limits. Thus, if a Forward Auxiliary limit is activated, the Stagehand Pro AC will read the limit as a Forward Limit. Similarly, if a Reverse Auxiliary limit is activated the Stagehand Pro AC will read the limit as a Reverse Limit. Auxiliary limits use NEMA ML1 connectors.

The Auxiliary Limits were originally conceived to be used with a Floorpocket and trapdoor (sunroof) application. This way, if you placed a Normally Open limit switch that is connected to the FWD Aux Limit input of the Stagehand Pro AC in the open position of your trapdoor (sunroof), this would prevent the lift from moving forward (or up) until the trapdoor (sunroof) is open. Similarly, you can do this with the REV Aux Limit to prevent the trap door from closing while the lift is in its raised position by placing a Normally Open limit switch where the limit is struck when the lift reaches its lowest position and is clear of the trapdoor (sunroof). If you are not using a trapdoor (sunroof) with your Floorpocket, you do not need Auxiliary Limits for your system. If you are not using a trapdoor (sunroof) with your Floorpocket, simply insert the included auxiliary limit jumpers to clear the limits. The graphic below shows how the limits could be placed for this system.

The graphic below shows the logic of how the interlock system controls the ability for motion to take place.
