Dimensions of the Belt Scale Controller JY**0B1

Technical parameters of the controller

Inputs

Static & Dynamic Calibration
Static Calibration uses load cell sensitivity and load cell capacity to calibrate the weight signal. Dynamic calibration allows calibration of weight when the belt is running knowing the platform weight(kg) or the belt loading (kg/m)
Flowrate Set point
The setpoint is the flowrate of material the belt conveyor is carrying. The controller can control the local setpoint ,which is set via the keypad or remote analog input.
Digital Inputs
There are 3 digital inputs. Terminal X*0 (1 ,2) is used to confirm the events. Terminal X9 (1,2) is used to stop the controller and terminal X9(3,4) is used to run the controller.s
Tacho input
The tacho input is used to measure the speed of the belt. To make a calibration, you need to run the belt at a constant speed to get a constant tacho input.
JY**0B1 can accept a wide range of speed sensors, including proximity switch ,Namur switch, stepper motor and encoder.
Zeroing
The weight of the unloaded belt is averaged over one or more complete belt revolutions and the resulting value is kept as the dynamic zero.
While in zeroing, any small drift in the weight measurement or materials build up on the weigh platform is automatically zeroed out. This ensures that with no products on the belt ,a zero flowrate is recorded.
Limits
The low and high limits have adjustable setpoints which may be programmed to operate on any internal signal.
Batching
The controller can be used to batch out a desired weight by stopping the conveyor when the weight has pass the weight platform. A pre-act weight can be adjusted to shut off the conveyor before the target weight is reached allowing time for the conveyor to stop and allowing the correct batching weight to be reached.
Loop Control
The controller compares the flowrate with the setpoint . A proportional/integral ( PI ) control technique alters the analog control output to maintain the flowrate at setpoint. It makes the belt scale get the desired flowrate very quickly and also make it respond to changes in setpoint rapidly.
Events Collection
Process events are collected for operation with external equipments.( Speed sensor etc.)

Internal Signal	The total of material The controller incorporates a totaliser which totalise the weight of material through the belt scale. The totaliser can be reset to zero easily. A pulse output is available to operate external counters. The total is retained after a power failure.
Output	Analog control output An analog control output is used to drive a frequency inverter to change the speed of electric motor in order to get vary the belt speed. Analog feedrate output An analog feedrate output reprensents the feedrate of the belt scale and can be connected to other instruments. Analog I/O Scaling The range of analog outputs can be adjusted over the full 0 to 0 mA. A voltage output can be easily acquired by connecting a resistor to the output. The analog feedrate output can be changed into an analog output that represents belt speed or belt loading(kg/m) Digital Relay Output* There are 7 digital relay outputs to operate from 7 internal signals, such as start/stop the electric motor, start/stop the pre-feeder and so on
Communications	RS2 and RS5 ports are available. They are used to connect to some systems. The protocol is either ACSII output for example to drive a printer or Modbus for interactive communications. Baud rate and node address are programmable.
