Insert the wires in the correct arrangement into the RJ45 modular plug, check that the wires
are firmly inserted, and then crimp the plug with a RJ45 modular plug crimp tool.
Finally, check that the plug has been crimped on properly by testing the connection with a
LAN cable tester.
(5) Insert the RJ45 connector into the TDLS8000 Ethernet port and the round crimp-on terminal
at the end of the shielded wire to the functional ground terminal (M4 screw) inside the SCU.
3.3 Optical Axis Adjustment
When wiring is complete, turn on the power, and adjust the optical axis.
CAUTION
The TDLS8000 is a Class 1 laser product. As such, the laser level of the product is safe to the
eyes, but do not intentionally look at the laser light source. The TDLS8000 laser unit emits laser
beam as soon as the power is turned on. Turn the power on after installing both the laser unit and
sensor control unit to the process flange or flow cell (in a condition where the laser beam is not
irradiated outside the process).
When the TDLS8000 is turned on, transmission is indicated on the display of the LU and that of
the SCU. The LU displays the value with 4 digits, and the SCU as “Trans **.*%.” The alignment
flange needs to be adjusted using the angle fine-adjustment nut so that this transmission is
maximized. (See Figure 3.16.)
The transmission display is updated every analysis period. The standard analysis period is 2 to 5
seconds. For details on the analysis period, see “Appendix 5 What Is an Analysis Period?”.
While adjusting the optical axis, check the updated display showing the most recent
transmission. Note that it is possible to determine when the transmission is updated by the way
each display changes its displayed content.
For details, see “1.2
Name and Function of Each Part”.
