دستورالعمل نصب و راه اندازی

دستورالعمل نصب و راه اندازی:Mounted on vertical column or directly mounted on plane by hoop or bolt, installation height should be as high as possible.

Connection description: connect by 3.2.

چراغ نشانگر:when the power light is bright and the power supply is normal, the status light is on the communication between the instrument and the lower computer.

Instrument appearance diagram

Light state:

1) Function test of power indicator:When the controller is connected to the power supply, power lights have been shown in the green.

2) Function test of connection indicator:When the controller is connected to the power supply and switchboard, the connecting lamp has been shown green.

3) Function test of communication indicator:When the controller and the lower machine have information transmission, communication indicator bright; after finished light extinguish.

4) Function test of status indicator:

a) When software sends commands to the instrument or instrument upload data, status indicator bright؛

b) When the instrument and monitor have information transmission, status indicator bright,after finished light extinguish.
