Installation

■Input Codes

Operation Examples of RBI and RBO

Zero suppression functions and RBO is low when the display is 0, the decimal point

is not lit, and RBI is low.

Example 1: Zero blanking is not required and the RBI input and RBO output of each

digit are open.

Example 2: Wired as shown when there is zero blanking. If the data of the rightmost

digit is 0, 0 will be displayed.

Example 3: Zero blanking is valid for only the digits on the left of the lit digit and

decimal point.

Example 4: Zero blanking is valid for the second digit and the following digits that are

on the right of the lit digit and decimal point. If the first- to fourth-digit

values are all 0 and the decimal point is lit with the fourth digit, 0. 0@@

will be displayed. (There is no data in @@.)

Note: Use RBO output for the connection with RBI input only.

•The display color will be green if the color control input of terminal 2 is set low and red if it is set high.

•All inputs are pulled up internally. Therefore high can be open.

*1 Either low or high.

*2 Even if the data input is 0 and RBI is low, "0." will be displayed if DP is low.

*3 Indicates the minus symbol (-) on the 7-segment display.

Procedure for Making Face Plates for

M7E-02 Unit Display Unit

Custom face plates can be made according to the following

guidelines.

1. Prepare a blank Unit Display Unit (M7E-02UR2-A or M7E-

02UG2-A) for the desired lighting color.

2. Take transparent polyester film (with thickness equivalent to

0.188) and cut it to the following dimensions.

3. Print solid black on the film covering all area except the character

and so that the desired unit character is within the character

display range (with the unit character transparent).

4. Install the completed face plate into the Unit Display Unit.
