3. How to Install
3-1. How to Connect Load Cell
Connect the load cell connector to the load cell port on the back of the indicator.
* How to connect the load cell to the connector.

Pin Function
1 EXC+
6 SEN+
2 EXC-
7 SEN-
3 SIG+
4 SIG-
5 SHIELD
Note 1. When 4 line load cell is used, connect EXC+ and SEN+ to '+' power supply terminal
in the load cell input, and connect EXC- and SEN- to '-' power supply terminal in the
load cell input.
* Relationship between the load cell output and input sensitivity.
The input sensitivity of this product is maximum 0.2uV/digit or more.
The following equation should be satisfied upon the system design.
Example 1) Number of load cell: 4 ea
Rated capacity of load cell: 500 Kg
Rated output of load cell: 2mV/V
Value of a division: 0.10 Kg
Applied voltage of load cell: 10V (= 10,000 mV)
According to the equation
(10000 mV* 2mV * 0.1Kg)/(500Kg * 4) = 1
≥
0.2uV
As the calculated value is greater than 0.2uV, this weight system design has no problem.
Applied voltage of load cell x Output voltage of load cell x Value of a
division
0.2uV
≤
------------------------------------------------------------------------------------------------
Rated capacity of load cell x Number of load cell
