What safety features do you bypass when you use the local control rocker switch?
Typically if a feature is software based in the controller then it will bypassed with local control.
These bypassed features include:
- Soft Limits
- Load Profiling
- Phase reversal check - Caution: You can back wind the drum while using local control
- Variable speed hoists will run at limited speed, approximately 30 FPS
- Motor not moving notification- If the timing chain breaks the motor will still move possibly damaging other things in the hoist
Any safety feature that is hard wired into the control card:
- Hard Limits
- Slack line
- Hoist capacity- still can't overload the hoist
- Motor Brake
- Load Brake
- Overload relay
