BEZEL OPTIONPERFORMANCE in percentage of spanBezels are used to adapt the 48N Series to an existing panel
cutout. In order to replace the 48 Series products, use theone attached to the 48N Series as standard. When theexisting panel is cut according to DIN standard, specify ‘/D’suffix code.
For a new installation, no bezel is required. Please refer to‘Mounting Requirement’ and mount the 48N directly.
Ingress protection is invalid when the 48N is mounted with abezel, or when multiple modules are stacked side by side.

SCALE PLATE■ WHAT MUST BE SPECIFIED WHEN ORDERINGFollowing two methods can specify scale plate.
a) Using ‘Scale Plate Designer’
Access ‘Design Scale Plate’ in the our web site. Scale plate can be designed in this web site.
By function below, it can be easy to create standard design or original design.
[Design Automatically]
Entering Minimum, Maximum, and Unit allows to create automatically a scale plate.
Maximum created scale division number is ’54.9’. Use [Specify Division Number], if division number more than ’54.9’ isrequired (Maximum 100 division).
[Specify Division Interval]
Division Interval can be specified according to the application.
[Specify Division Number]
It is available to create originally with scale division number, length of line, position, character size, font and detailed position.
After designing is completed, register code is issued. Place the order with this code.
Once scale plate is designed, it is recorded. The register code can be used any number of times.
b) Specifying scale range and display unit when placing the order
It is available to create by specifying scale range and display unit for right and left.
Regarding design of scale plate such as division number, length of division number line, and character font, they are sameas above [Design Automatically], we design them.
■ DESIGNING BY ‘DESIGN AUTOMATICALLY’How ‘Design Automatically’ creates scale design is described succinctly below.
■ TYPES OF DIVISIONS
Five (5) types of divisions are used depending upon the scale span, which determined by the following equation:
Scale Span = (Max. range value – Min. range value) x 10n
where n = integer (used to limit the calculated scale spanto the minimum of 1.1, below 11.0.)
The number of divisions is automatically determined by the scale span.

• Type 1: 1.1 Scale Span < 1.3
Number of divisions: 22 to 25.9
Scale: Starts at 0, increments by 0.02 / 0.2 / 2 / 20 /200. Min. and max. values indicated. 4 digits
including negative sign and decimal point.
Division lines: Long, Short, Medium, Short, Long
(4 divisions repeated)

MinimumDivisions• Type 2: 1.3 Scale Span < 2.0
Number of divisions: 26 to 39.9
Scale: Starts at 0, increments by 0.03 / 0.3 / 3 / 30 /300. Min. and max. values indicated. 4 digitsincluding negative sign and decimal point.
Division lines: Long, Short, Medium, Short, Medium,Short, Long (6 divisions repeated)
