● Weighing device debugging under other circumstances:
If the following reasons occur, the working parameters of the weighing device need to be revised again.
The modification method is the same as above.
1. The elevator changes the decoration of the car, so that its self-weight changes;
2. The pull of the wire rope appears large imbalance phenomenon;
3. The phenomenon of rushing to the top and squatting to the bottom;

2.Installation Method：
3. Precautions for installing the controller and sensor：
3.1 The controller part should be installed in the control box on the
top of the car, and it is better not to be close to the elevator
electronic weighing device transformer, governor and other
equipment. In all cases, sensors and controllers shall be installed
away from heat sources;
3.2 "C" type sensor The sensor is installed above the bearing beam,
and the connection between the controller is better than 110V, 220V and other power supply in the same wiring slot;
3.3 Connect the sensor wiring port to the PG port of the controller, and connect PV to the power line according to the
requirements of the weighing device. Be sure to pay attention to the voltage level;
3.4 Power on the weighing device after the check is correct, and the controller shall be displayed in the corresponding
working mode.
The green part is welding accessories,
tatally 2, each "left , right, back" 2
welding points; The user can weld the
Fukien with the load-bearing beam.
