Summary.
LD628 remote display can be used as second weight display, by receiving the data of weigh82ing display controller, used in the second weight indicator. Connecting through RS232, RS422, 20mA current loop or SIF interface and the Japanese UNIPULSE, Japan AD, METTLER TOLEDO - United States,and a variety of weighing display controller of our company,the LD688 remote display display the weight, total number of packages or accumulative weight information (depending on the weighing display controller to send data ). The LD688 can receive most of two weighing display controller weight data.
For example: LD628 remote display is mainly used in the packing scale packaging ( packaging weighing instrument scene in the control room ).

Preliminary test:
Open the packing box, according to the random and accessary packing list view components are complete. If there is a lack of parts or components damage, please contact with the company, in order to obtain properly processing.
Make sure each part intact after the instrument from inside the box is taken out, then the installation and wiring.
Installation guide:
According to the installation requirements in the control cabinet open rectangular holes.
Remove left inserting plate fixed by two screws, and remove the left inserting plate.
The instrument from outside is inserted into the opening of the control cabinet.
Back of the instrument to fit around the flapper, and tighten the two screws.
Serial interface COM1:
LD628 remote display serial port COM1 including RS232, RS422, 20mA current loop and SIF multiple serial interface. Serial port COM1 is used to receive the first weighing display controller weight data.
