1 Purpose and Features:
The flat Grinder is the required instrument in the national standard GB5211.19 "Determination of relative tinting strength and diluted color of coloring pigments by visual comparison method".
This machine can be used as a special physical performance testing instrument for the pigment, paint and ink industries. The whole machine is compact in structure, simple in appearance, easy to change the number of revolutions and loads, and easy to assemble and disassemble the glass plate. Microcomputer control, LCD display, easy parameter setting. When the input parameters are wrong, the controller will automatically display "invalid input", which achieves the purpose of reliable control and simple operation.

4 Connection between the flat Grinder and the controller:
4.1 Pay attention to the direction of the socket when connecting, and use it after checking that the connection is correct.
5 Check before use:
5.1 Every time you use the flat Grinder, check whether the positioning rings of the upper and lower grinding discs are tightened. If not, tighten them before using them.
5.2 When running without load, the upper grinding disc needs to be opened, and the turning of the lower grinding disc should be counterclockwise.
5.3 The instrument is powered by three-phase four-wire 380 volts, and should be connected to the ground wire (zero wire) for use, otherwise the electric control box will not work.
6 key functions:
6.1 "Number" key: input the value of "set number of circles".
6.2 "Run" key: The machine starts to run.
6.3 "Stop" key: the machine stops running.
6.4 "Cancel number setting" key: cancel the number input, return to the display when the machine is turned on and the machine stops running.
6.5 "Stop counting" key: "Number of revolutions" and "Accumulated times" stop counting.
6.6 "Reset A" key: clear the counter of "number of revolutions".
6.7 "Reset B" key: clear the "cumulative times" counter.
7Operating steps:
7.1 Put a certain amount of sample and blending agent on the lower grinding disc, use a knife to mix it into a slurry, then move the blended slurry to the center of the lower grinding disc, and put down the upper grinding disc, so that the positioning shaft core and the positioning block are buckled, Pull the eccentric handle down again, and hang up the required weight.
7.2 When the power switch of the controller is turned on, the buzzer will make a beep.
7.3 Then the LCD screen displays in turn:
Company Name:
Instrument Model: "PM240 Flat Grinder"
URL:
Product serial number: □□□□ (Example: 0001)
Date of manufacture: □□□□—□□—□□ (Example: 2005—06—28)
Simple operation: "Please enter the set number of laps, and then press the operation button!"
7.4 Then the LCD screen enters the operation interface to display:
"Set laps: "
"Number of revolutions: 0000"
"Accumulated times: 00"
7.5 Press the number keys on the keyboard corresponding to the thousands, hundreds and tens digits of the set circle number to input numbers in turn. If you accidentally press the function key at this time, the LCD screen will display "invalid input", and you can continue to input numbers. When the input is full of four digits, but not 0000, the "run" button can be pressed. (For example: if you want to run 10 laps, you need to input 0010), if you deliberately input 0000, the instrument will tell you "Input error, please re-enter". The buzzer will emit a "beep" every time a digit is input, indicating that the input is valid, otherwise it indicates invalid. If you find that you have entered a wrong number, please press the "Cancel Setting Number" button, and the number after "Setting Number of Circles" will be canceled immediately. If it is confirmed that the input is correct, please press the "Run" button, and the relay will be closed at this time, and the motor will start to run. Every time it turns a circle, the "turning circle" will automatically add 1 cumulatively. When the number of running circles is the same as the set number of circles, the motor will stop running automatically. At this time, the buzzer will emit a "beep beep" alarm sound, and the "cumulative times" will automatically increase by 1. At this time, pull the eccentric handle to separate the upper and lower grinding discs, pull the positioning handle outward, and push it up at the same time, open the upper grinding disc, and observe the sample.
7.6 If you want to run again according to the number of laps set last time, just press the "Run" button directly; if you want to stop midway, you can press the "Stop" button. If you press "Reset A", the "Number of Operations" counter will be automatically cleared; press "Reset B", then the "Accumulated Times" counter will be automatically cleared, and at the same time, a "beep" will sound. To continue working, just press the "Run" button, and the machine will continue to run until it reaches the set number of laps.
7.7 If the machine is going to run for a long time, the counter should stop counting. Please enter any four-digit number first, but not 0000. Then press the "stop counting" button, and at the same time make a "beep". It means that the button is valid, otherwise it is invalid. Then press the "Run" button, so that the machine can run for a long time. At this time, the "Number of running circles" will display "STOP"; Make a "beep" sound to indicate that it is valid; the machine will return to the original counting state. After reaching the set number of laps, the machine stops automatically. If the machine wants to stop running halfway, please press the "Stop" button.
7.8 If the "cancel setting" button is pressed during the operation of the machine, the whole machine will stop running. At the same time, clear the values of "set laps", "reset A" and "reset B".
7.9 If water cooling is required, connect the water nozzle of the upper grinding disc.
8 Notes:
8.1 After each work, the upper and lower glass should be wiped clean, with appropriate paper placed in the middle, and the upper grinding disc should be put down to avoid damage to the glass plate.
8.2 The set number of laps cannot be 0000.
8.3 If the input "setting number of laps" is less than four digits, all function keys on the keyboard will be invalid.
8.4 The flipping and closing time of each operation button is greater than 0.5 seconds; if the flipping and closing time is too short, the MCU will be regarded as an interference signal.
8.5 Every time the machine is turned on and off, there must be an interval of 10 seconds, and the LCD screen will be cleared after the machine is turned off; otherwise, an error will appear on the screen.
8.6 If the counting pulse device fails, the number in the "number of rotations" will not add "1" cumulatively, and the machine will not stop automatically during operation.
9Maintenance:
9.1 The controller can be placed close to the flat Grinder, but strong vibration should be avoided. After each work, the power should be turned off and covered with a cloth.
9.2 After the instrument has been used for one year, it is necessary to open the cover and fill the gearbox with oil.
