Frequently Asked Questions
Q: How accurate are the integrated load sensors?
A: The load sensors provide accuracy of ±0.5% of rated capacity, which is suitable for most stage applications. High-accuracy versions with ±0.25% accuracy are available for certified lifting applications.
Q: Can the load data be integrated with show control systems?
A: Yes, the load sensors provide standardized outputs including 4-20mA, 0-10V, and CANopen. This enables integration with most stage automation systems for load-dependent control logic.
Q: What happens if one lifting point shows an unbalanced load?
A: The system can be configured to alert the operator, automatically pause operation, or take other safety actions based on the degree of imbalance. This helps prevent damage to scenery and equipment.
Q: Is calibration required periodically?
A: We recommend annual calibration verification to maintain accuracy. Our service team provides calibration and recertification services worldwide.
