1.1Overview
This operation manual provides detailed information about the installation, operation, calibration, and maintenance of the belt scale conveyor controller.
1.2 Introduction
The feeder controller includes on-site installation and panel installation. It adopts microprocessor control to process the weight signal and belt speed signal of the load cell, calculate the flow rate and cumulative amount of the flowing material, and display it on the instrument. At the same time, the instrument has a built-in PID regulator, which provides a standard 4-20mA output to control the operation of the feeder. And provide remote pulse count output. An RS-232 or RS-485 interface can be added to communicate with the host computer using a communication board. The instrument adopts an all-Chinese operation interface, which is intuitive and easy to operate. And has a variety of automatic detection functions, which is convenient for users to calibrate and maintain.
1.3 Environmental parameters
1. Indoor/Outdoor The installation location should be close to the load cell. Pay attention to dust and moisture.
2. Storage temperature -40℃ — +70℃
Operating temperature -10℃ — +50℃
3. Maximum relative humidity: 95%
1.4 Power supply
·220VAC±10% 50Hz
·Fuse 2A
·EMI/RFI filter
1.5 Load cell
·The instrument provides 10VDC ± 10%, 200mA excitation power, 4 load cells can be connected in parallel
·Sensitivity, 0.5mV/V – 3.5mV/V
· Maximum input signal 33mV
· Weighing sensor shield grounding
· Use excitation compensation circuit when the cable distance is greater than 60 meters (not more than 900 meters)
Jumper selection local or remote compensation
1.6 Mainboard digital input port
The instrument mainboard provides 3 programmable input ports to receive dry contact switch signals.
1.7 Mainboard digital output port
The mainboard of the instrument provides 3 programmable output ports, 24VDC open collector output. It can directly drive the control relay.
1.8 Communication board
The instrument can be installed with a communication board and can use standard RS-232, RS-485 serial interface to communicate with the host computer to collect instrument data and operate the instrument.
Chapter 2 Installation
2.1 Overview
This chapter includes the installation, configuration, and initial programming of the feeder controller.
The instrument should not be installed in a place where the environmental conditions change drastically. Try to install it indoors, otherwise, it is necessary to install protective facilities to avoid direct sunlight, humidity, collisions, and severe mechanical vibrations. The meter can be installed at the farthest distance of 900 meters from the load cell.
2.2 Installation
The wall-mounted integrator is vertically installed on a solid, flat wall through the four mounting holes at the back of the chassis.
2.3 Safety warning
warn
Do not perform any installation, operation, and maintenance operations before reading the following warning regulations
1. Do not connect to the power supply of the meter until you fully understand the manual.
2. Strictly follow the warnings and operating procedures in this manual to avoid personal injury and equipment damage.
2.4 Wiring
1. Make sure the power is off
2. Do not route signal wires and power wires or other cables with strong electromagnetic interference in the same conduit.
3. The instrument housing and conduit should be grounded at one point.
4. Check that all connections are correct and secure.
5. It is strictly forbidden to use a “megohm meter” to check the circuit.
6. A circuit breaker (maximum 20A) should be installed in the power supply line. The installation position of the circuit breaker should be easy to operate and clearly marked for this instrument.
7. All ducts should enter from the bottom of the chassis, not from the top or side of the chassis.
Notice:
1. Do not shorten the cable of the load cell
2. The sensor signal line should not use the same conduit as the power line.
3. The shielding layer of the shielded cable should be grounded at one end and connected as shown in the figure.
4. The chassis must be grounded.
2.5 Initial settings of the instrument
After the mechanical and electrical installations are completed, initialize the instrument and program it. The following parameters should be entered before calibration.

Alarm Generate an alarm message to remind the user. If the alarm output function is set, the output can reset the alarm output until the alarm is reset or the fault is eliminated.
Downtime Generate alarm information, such as setting the stop output function to generate a non-resettable stop output signal
until the fault is eliminated.

Convey Belt scale debugging method and operation
Step 1: Establish a test cycle: (It is not the first time to calibrate the meter or change the speed sensor, you can skip this step.)
1)To idle the belt at maximum speed, press the “Menu” key twice to display the “Menu 2” page, press the “Down ↓” key until the “Establish Test Cycle” page appears, press the corresponding soft key under “Manual”, and the page “Max Speed” appears “Start the belt” prompt, press the “Continue” button, the page displays “Enter the belt cycle length***”, press the “Enter” button, the page displays the “Enter belt rotation cycle number” prompt. Enter the number of belt weeks “*” weeks. Press the “Enter” button. Then enter the belt running time ***S, press the “confirm” button, the page will display the belt running countdown, and wait until the countdown reaches 0. The page displays “Establish Test Cycle”, press the “Continue” button. The page displays “Maximum belt speed…”, press the “Enter” button. Press the “Run” button again. The establishment of the test cycle is complete.
Step 2: Zero adjustment (tare):
1) Idling the belt at maximum speed, press the “Menu” key once, “Menu 1” appears, press “Zero Calibration”, and then press the “Start” soft key, and the instrument will count. When the timer reaches 0, the page “Change the new zero point value?” appears on the page, press the “Change” button, and then press the “Run” button. The zero point calibration is complete. Repeat the zero adjustment operation 2 times. 2) Frequent zero adjustment operation is necessary to ensure accurate measurement.
The third step, the first method: hanging code calibration:
After the zero adjustments are completed, stop the conveyor belt, hang up the 10KG code (depending on the specific weight), start the belt at the maximum speed, press the menu button once, “Menu 1” appears, press “Interval Calibration”, then press the “Start” button, the instrument Proceed to time. When the timer reaches 0, the page “Change the new interval value?” appears on the page, press the “Change” button, and then press the Run button. The interval check is complete. Repeat the interval calibration operation twice. Record the interval value at this time and press the “Run” key to exit。
The third step and the second method: physical verification:
First accurately weigh out the physical weight T, after the zero adjustments are completed, perform physical verification, in menu 1, press physical verification, and when the red mark passes the mark point, press start. At this time, the material will start to pass, and wait until all the materials pass the belt scale. , And wait until the red mark passes the mark point, press the finish button, enter the standard weight T, and press the change button to complete the calibration. Go through the material again according to the above method and observe the error between the displayed weight and the actual weight.
Note: In the third step, one can be selected reasonably according to the use environment of the field equipment.
The key formula of belt scale: In menu two-interval calibration, press Manual, there will be an interval value. This interval value can be changed manually. Specific formula: new interval value=(actual weight/display weight)*old interval value or new interval value=(1±error to be adjusted)*old interval value.
For example, increase the amount displayed on the instrument by 0.5%, and the new interval value=1.005*old interval value. For example, reduce the amount displayed on the instrument by 0.5%, and the new interval value=0.995*old interval value.
