Example 1: The RBI input and RBO output of each digit are open when zero suppression is not being used. Example 2 Example 2: Wired as shown to display only 0 for the rightmost digit when zero suppression is being used. Example 3: Zeros are suppressed only for the digits on the left of the digit where the decimal is lit when both zero suppression and a decimal point are being used. Example 3 Example 4: Zeros are suppressed to the right of the first digit below the decimal point when both zero suppression and a decimal point are being used. If the first-to-fourth-digit values are all 0 and the decimal point is lit at the fourth digit, 0.0@@ will be displayed. (There is no data in @@.)

Visibility may be significantly reduced if the Unit is used outside or in locations where the ambient brightness exceeds the brightness of the M7E. The product is not drip-proof. Use the product where it will not be subject to water or oil splashing. • Use the Units in areas not subject to vibration or shock in excess of specifications. Mounting Projecting tip Procedure for Making Face Plates for M7E-01 Unit Display Unit Custom face plates can be made according to the following guidelines. 1. Prepare a blank Unit Display Unit (M7E-01UR2-A or M7E01UG2-A) for the desired lighting color. 2. Take transparent polyester film (with thickness equivalent to 0.188) and cut it to the following dimensions. Slot Character display range • Link the Units by snapping the projecting tips and slots together. There are projecting tips made of resin on the side of each Display Unit. Be sure not to drop the Display Unit, otherwise the projecting tips may break. • To undo the linkage, use a slotted screwdriver as shown in the following figure and press the upper and lower tips while separating. Face plate dimensions 0 18.6 −0.3 5 7 0 31 −0.3 Face plate dimensions Installation environment 11 Character display range 3. Print solid black on the film covering all areas 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.

Check the output circuit of the connecting device and use a pull-up resistor if necessary. • All M7E models used on a single Mother Board must be identical. Connecting or Disconnecting the M7E When connecting the M7E to or disconnecting the M7E from the Mother Board, hold the front panel of the M7E or the case and be sure to apply appropriate force on the top and bottom of the Mother Board alternately.
