Operation of the Zero Gravity Gen. 2 Controls
The Zero Gravity Gen. 2 controller operates in Standard and Float modes.
Please note warnings below for safe operation.
- Press Emergency Stop button to stop movement in case of an emergency.
- Make sure electrical wiring to the balancer conforms to all relevant safety codes and regulations.
- Make sure all electrical connections are secure before applying power.
- Never operate equipment with damaged, frayed, or twisted electrical cables.
- Before each shift or initial use, inspect the balancer for visible wear and damage.
- Immediately disconnect main power if balancer is damaged.
- Only licensed electrical technicians, trained on this product, should be allowed to access electrical components to perform troubleshooting/diagnostics or repair.
- Troubleshooting/Diagnostics of the system by licensed electrical technicians is limited to visual inspection of components and subassemblies once the enclosures are opened.
- Follow a Lock-out/Tag-out procedure before accessing electrical components to assure power to the system has been disconnected.
- Disconnect air supply to balancer prior to maintenance.
Standard Operation - Move load by acting upon the Handle
Red light stays on for two seconds immediately after powering up the balancer. During this time, load cell and handle sensor resting values are calculated by the controller. When the Red light turns off, balancer is ready for operation by using the handle to move the load upward and downward (see Fig J).
If the resting values of handle and load cell sensors are out of expected range, the Red light flashes rapidly. Balancer is inoperable in this state.
Float Mode - Move load by acting upon the load itself
Engage float mode - To engage float mode, release the handle. Float mode will be triggered by lack of contact with the handle. While float mode is engaging, the Red light on the control box will illuminate. Do not touch the handle while the controller is calculating load. Float mode is engaged and calculation complete when the three yellow lights on the controller illuminate.
- Do not apply force on the load (upward or downward) while float mode is calculating. This will cause faulty calculation of the weight and result in load drift.
Move loads up and down by acting directly upon the load itself.
Disengage float mode - Float mode disengages automatically once the handle is touched causing the yellow lights on the controller to turn off. When Yellow lights turn off, controller reverts to Standard Operation. Use the handle sleeve to move load upward or downward.
