Key points for debugging electronic belt scale

1. Please refer to the wiring for detailsThe instrument wiring section of the electronic belt scale user manual.

2. Main differences from the original instrument:

Chinese or English buttons can be selected.

16 buttons for menu and shortcut operations (with button tone).

Equipped with automatic encryption, key encryption, key decryption, digital setting, digital calibration, and interface testing functions.

3. Operation interface

(1) Horizontal embedded operation interface


(2) Vertical embedded operation interface

(3) Wall mounted operation interface

(4) Status indication

4. Key operation

Automatically return to the main display interface when there is no operation within one minute (except for the F2 system calibration and F6 factory calibration processes).

5. Menu Actions

(1) Quick Actions

(2) Speed calibration:

The first step is to enter the belt length L (or on-site measurement) in the user information into the belt length under the basic measurement parameters

The second step is to make a mark on the belt and measure the time T of the entire belt turn (in the timing of the entire belt turn under speed calibration). The instrument will automatically countdown and count to zero. Automatically calculate the belt speed. If the speed changes within a certain range, the speed coefficient can be increased a bit (the speed coefficient can be adjusted in the range of 0-200. The larger the speed coefficient, the more stable the speed is, but it cannot be adjusted too much, causing the speed to gradually approach the belt speed for too long when starting the machine) 6.1.1. Setting of DI input port

6. Input port wiring: from the common end of the COM port to DI1, DI2, and DI3 (3 pairs)

(1) The input port can only input dry node signals (the instrument provides 5V power supply internally).

(2) Setting of DO output port

Enter the interface settings menu. (On the interface where the wire is connected, such as DI 1 port), press the up and down keys to select the interface menu, select DI 1 port, and select external peeling (the instrument will automatically peel when DI 1 port is closed).

(3) Enter the interface settings menu. (On the interface where the wire is connected, such as DI port 2), press the up and down keys to select the connection

Menu, select DI 2 port, select chain code calibration (the instrument will automatically calibrate the chain code when DI2 is closed).

7、Setting of cumulative pulses for the instrument

The cumulative pulse of the instrument is divided into low-speed pulse equivalent and high-speed pulse equivalent.

Low speed pulse equivalent wiring corresponds to DO1+DO1-, DO2+DO2-, DO, 3+DO3-, DO, 4+DO4- (select low speed pulse equivalent in the setting of DO output port)

The high-speed pulse equivalent wiring corresponds to VIN and PO (select high-speed pulse equivalent in the DO output port setting, which can be accurate to 1kg or 1 ton). Note: VIN and PO ports are transistor outputs and can only be connected to 24V PLC input points. DO1+DO1-, DO2+DO2-, DO, 3+DO3-, DO, 4+DO4- ports are relay dry contact outputs. Other operations of the instrument are similar to those of the instrument, please refer to the instrument manual for details.

8. Instrument grounding protection

This product is a weak current device and should be isolated from strong current devices during installation.

In order to prevent personal injury caused by electric shock accidents and isolate this product from strong interference sources, please make sure to connect the instrument grounding terminal separately from the ground, and the grounding resistance is required to be less than 4 amps; Omega;.

9. Scale body grounding protection

In order to prevent personal injury caused by electric shock accidents and isolate the weighing sensor and speed sensor from strong interference sources, it is necessary to connect the weighing body to the grounding network of the electronic weighing instrument, and the grounding resistance should be less than 4 amps; Omega;.
