B (2 ) 2 C C (2 ) • Decimal display uses 0 to 9; nothing will be displayed for 3 D (2 ) D higher values. DP Data input The decimal point lights. Operates independently from the LE terminal. LE Control input Latch input: The immediately preceding display condition is retained. R/G Control input Set low for green display and high for red display. (See note.) Note: Only for the M7E-02DRGN2. G Power supply 0-V power-supply (ground) input terminal (GND). ■ Input Codes Operation Examples of RBI and RBO Fourth digit Third digit Second digit First digit Zero suppression functions and RBO is low when the display is 0, the decimal point is not lit, and RBI is low. Example 1 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 2 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 Example 3 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. Example 4 3 M7E Negative Logic Unit • 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.

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. Face Plate Dimensions 0 27.6 −0.3 2 0 45.9 −0.3 15 18 Character display range 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.
