- The measuring system is designed for use in an industrial environment. It is used for
displacement, distance and movement measurement, thickness measurement,
measuring the position of parts or machine components
- The measuring system must only be operated within the limits specified in the technical data.

ged in the event of malfunction or total failure of the sensor.
Take additional precautions for safety and damage prevention in case of safety-related applications.

Sensor Cable, Optical Fiber
The sensor is connected to the controller by means
of an optical fiber.
- Do not shorten or extend the optical fiber.
- Do not pull or carry the sensor by the cable.
Do not kink the sen-
sor cable.
Do not squash the
sensor cable, do
not use cable ties to
secure it.
Do not pull the sensor
cable over sharp
edges.
Do not pull on the
sensor cable.
The plugs may only be cleaned by persons with the
appropriate expertise.

General Rules
Do not
- any contamination of the connector, e.g., dust
- apply any mechanical stress to the optical fiber
- curve the cable to a significant extent
Never bend the sensor cable more tightly than the per-
mitted bending radius.
R
If the cable is immova-
bly routed:
R = 30 mm or more
If the cable is movably
routed:
R = 40 mm or more

dark reference function.
Multifunction
Function 1
Function 2
Dark reference Starts the dark reference for sensor 1 or sensor 2
Mastering, Reset Mastering Starts or stops a master measurement of the selected signals
LED Switches the light source for sensor 1 or sensor 2 on/off
The functions can be assigned to the individual time slots. All time intervals are indicated by the LEDs flashing/lighting
up.

As standard, the Multifunction button has a lock that is activated 5 min after the controller is switched on.
Start of Measuring Range
An offset distance (SMR) between each sensor and the target must be kept.
Sensor SMR Target
Start of measuring range (SMR), the shortest distance
between the front surface of the sensor and the target.

Initial Operation
confocalDT 2421 / 2422
Initial Operation
iThe measuring system is ready to use approx. 10 s
after the controller is switched on.
To ensure precise measurements, let the measu-
ring system warm up for approx. 30 minutes.
The controller is shipped with the factory-set IP address
169.254.168.150.
You can query the IP addresses of the controllers that
are connected to a PC or network by using the sen-
sorTOOL.exe program. You can find this program on-
line at https://www.micro-epsilon.de/download/software/
sensorTOOL.exe.
Launch the sensorTOOL and click the button.
Select the controller from the list.
Click the Open Website button to connect the cont-
roller to your default browser.
The start screen of the controller software should now be
displayed in the web browser. You can configure the soft-
ware using the web pages or ASCII commands integrated
in the controller.
Selecting the Sensor
Go to the Settings > Sensor menu.
Select the connec-
ted sensor for the
relevant channel. Pay
attention to type and
serial number.
