J DISPLAY AND SPECIAL FUNCTION SETTINGS
Display Setting
The E3X-DA-N offers three display modes, which are Digital Incident Level display, Digital Percent display and Analog display.
•
Digital Incident Level Display: the incident level is digitally displayed.
•
Digital Percent Display: the threshold-based excess gain is displayed in percentage.
•
Analog Display: threshold and excess gain is displayed by two-color (red and green) bar graph.
Special Function Setting
The E3X-DA-N series has various functions that give users more flexibility in meeting a variety of application requirements.
•
Sensing Function: Enables users to choose either standard sensing distance mode, long sensing distance mode
or high speed mode
•
Timer Function: Enables users to select various OFF-delay timer settings from 0 to 20 ms (set in 1 ms increments) and from 20 to
200 ms (set in 5 ms increments). OFF-delay timer lengthens the duration of a short, high-speed signal so that it can be recognized as
input to Programmable Controllers during a scan cycle.
•
Flashing Function: Flashing red LED allows easier optical axis adjustment.
•
Display Hold Setting: This function provides easy data reading during optical axis adjustment and high-speed detection by holding
the displayed value for a period of time. Displayed data gets updated every 2 seconds. Within the 2-second time frame, the maximum
or minimum value is displayed (data will be flashing).
•
Display Orientation Setting: Reversible digital display provides easy data reading from any mounting orientation.
•
Zero reset: When activated, this function sets the incident
level digital display to zero. This enables operators to easily
monitor the difference between the maximum incident level
and the minimum incident level.
•
Initial reset: Enables users to easily program the amplifier
back to the default (factory) settings.
•
Monitor focus: This feature is available on analog/digital
output models. Without "monitor focus", the E3X-DA-N has to
analyze an incident level range of 0 to 4095 to process a 1 to
5 VDC analog output. With the "monitor focus" function, the
E3X-DA-N can narrow the range of the incident level to pro-
cess a 1 to 5 VDC analog input by defining an upper and
lower limit of the incident level. As as result, the sensor's
resolution is increased.
Example: Monitor focus increases resolution over a narrow range Upper limit = 2400 and lower limit = 1000
