by set value 1 (output 1 is ON).
PASS is lit when the sensing object is between the points set by
set values 1 and 2 (output 1 and output 2 are OFF).
HIGH is lit when the sensing object is farther than the point set
by set value 2 (output 2 is ON).

MODE PROGRAMMING DEFINITIONS
Operation Mode Selector
Select one of the following modes with the operation mode
selector.
RUN: The sensor operates. No program input is accepted.
SET: Select this mode for setting values. The set values
will be written to the memory when the operation mode is
changed to RUN from SET.
UP Key
SET Mode: Used to change the mode setting or set value.

Mode A
UP Key

RUN Mode: Used to change the contents of the display.

UP Key
Monitor display
SHIFT Key
Used to finalize the mode or value setting or to shift to the next
digit.
TEACH Key
Used in the teaching mode. With the teaching function, the set
value will be input by locating the sensing object at an
appropriate position and pressing the TEACH Key. No set value
can be input if the sensing object is outside the sensing range.
s
LCD DISPLAY
Set Value Zone Indicators (SET Mode only)
Displays the location of the set values in the sensing range.
FINE: Displayed when the set values are in the guaranteed
accuracy range.
ROUGH: Displayed when the set values are outside the
guaranteed accuracy range, but within the sensing range.
NG: Displayed when the set values are outside the sensing
range. However, no program error will result even if NG
is displayed.
Example 1: FINE is displayed if set values 1 and 2 are within
the guaranteed accuracy range.
Example 2: FINE and NG are displayed if one of the set
values is within the guaranteed accuracy range and the other is
outside the sensing range.

Mode B
MODE Indicator
Displays the status of the present set mode. The set mode
display flashes while the E2CD is waiting for an input. It is
possible to select one of the following two modes on the E2CD.
MODE A: Deviation value setting mode. A standard value and
its tolerance are input in this mode.
MODE B: Upper- and lower-limit setting mode. An upper-limit
value and lower-limit value are input in this mode.
Set Input Indicator
Displays the status of the present value display. The set input
indicator flashes while the E2CD is waiting for an input.
IN1: The standard value is displayed in MODE A and the
lower-limit value is displayed in MODE B. The IN1 input
value will be the user origin in this case. Thus 0 is displayed
after the IN1 value is input.
IN2: The tolerance is displayed in MODE A and the upper-limit
value is displayed in MODE B.
Value Indicator
The 7-segment display of 3 1/2 digits (
1999) is possible. The
set input value (in the SET mode), monitor value (in the RUN
mode), and an error message will be displayed. One digit is the
same as the set resolution.
Monitor (RUN Mode only)
Displays the distance between the user origin and the sensing
distance.
RUN Indicator
Indicates that the E2CD is set to the RUN mode.
