Technical Guide | Mitsubishi HOPE-II Elevator Weighing System Adjustment
Accurate weighing system adjustment is essential for proper load detection in Mitsubishi HOPE-II elevators. Here are the key procedures for installation, commissioning, and maintenance.
🔧 Preparation & Adjustment
Ensure the elevator is ready for operation, with a 45–50% balance coefficient.
Check rope tension and weighing sensor installation.
Adjust the differential transformer spring length to 37.5 mm.
⚙️ Load Calibration
No-load: Set the MON switch to “1” and use “2” to check the empty-load data.
Half-load: Add 50% rated load and record the corresponding data.
Data Storage: Use the LDO/LDI switch to save the calibration data.
🔍 Overload Adjustment
Place 110% of the rated load in the car.
Adjust the WGH potentiometer until the overload detector activates.
💡 Maintenance Tip
Recalibration may be required after traction rope replacement, rope tension adjustment, weighing component replacement, or significant weighing data deviation.
