1.1 Overview
The Feeder Electronic Belt Scale is a measuring device for continuous and automatic weighing of materials during the conveyance of materials on a belt conveyor. It is characterized by a continuous and automatic weighing process, which can usually be completed without the intervention of the operator.
The weighing operation is usually carried out without the intervention of the operator.
The FH-05T/IOT Feeder Weighing Instrument is one of the three main parts of the Feeder Electronic Belt Scale, which consists of sensor, weighing frame and secondary instrument. This manual mainly focuses on the performance, installation, operation and maintenance of FH-05T/0T Feeder Weighing Instrument to help users better use this product. FH-05T/10T feeder weighing instrument is available in embedded and wall-mounted versions. By processing the weight signal from the load cell and the speed signal from the speed sensor, the instantaneous flow rate and totalized flow rate of the material are calculated and displayed on the meter.
1.2 Performance Parameters (a) Chinese and English menu display (b) Weighing Function
-The instrument can be connected to up to 8 loads of 3500 at the same time and obtains the signals from a speed sensor to calculate the flow rate and the totalized quantity. (c) Environmental parameters
-Indoor/outdoor Installation as close as possible to the load cell, protected against dust and humidity. -Storage temperature -40°C - +70° Operating temperature
-10°C - +50° -Maximum relative humidity 95% (d) Power supply -110/220/240 VAC, +10%, -15%; 50/60Hz, -Fuse
0.5A - EMI/RFI filter (e) Load Cells - Instrument provides 10% of 10VDC, 500mA excitation power supply with up to 8 load cells in parallel - Sensitivity 0.5mV/V- 3.5mV/V
-Maximum input signal 33mV
-Protective earthing of the load cell.
-Excitation compensation for cable distances greater than 60 meters (not to exceed 900 meters) Circuit jumper to select local or remote compensation (f) Digital Inputs on Main Board The main board of the instrument provides 8 programmable inputs to receive dry contact switching signals. (gq) Main Board Digital Output Ports The instrument main board provides 8 programmable output ports. The 8th output is an optical relay output (400VAC/DC,lamps) and the rest are transistorized OC outputs (24) DC,0.5amps). (h) Enclosure Panel-mounted type: metal housing Field-mounted type: with two types of metal housing and plastic housing Ingress Protection IP65 See the installation dimension drawings in Chapter 2 (Fig. 2-1, Fig. 2-3, Fig. 2-4).
1.3 INSTRUMENT FUNCTIONS The FH-05T/IOT Feeder Weighing Instrument is designed to work with the feeder and meets the needs of all measurement and control functions. The software part of all functions is solidified in the memory chip, and the instrument will automatically turn on the corresponding function when the user installs the optional expansion board or the operator selects it through the keyboard. The FH-05T/10T feeder weighing instruments have a powerful and user-friendly interface, which makes it easy for the operator to select functions, set parameters, operate and maintain the instrument using the keyboard. FH-05T/10T feeder weighing instrument functions are mainly divided into the following aspects:
-Measuring function
- Monitoring function
-Printing function
-Communication function
