3 Installation and Removal
3.1 Fitting the unit onto a DIN rail
The LM Technic processor is designed to be mounted onto a standard DIN rail.
To install the unit:
1) Ensure that a suitable DIN rail (DIN EN 50 022) is available and installed
correctly (refer to Appendix).
2) Refer to Fig. 3. Rest the uppermost groove on the rear of the processor
on the top lip of the DIN rail.
3) Push the bottom of the unit so that the sliding spring catch clips onto the
DIN rail.
3.2 Removing the unit from a DIN rail
1) Refer to Fig. 4. Insert a screwdriver into the sliding spring catch via the
slot on the underside of the unit.
2) Lever the sliding spring catch downwards so that it disengages from the
DIN rail.
3) Lift the processor off the DIN rail.
3.3 Electrical connections
The LM Technic processor is designed to be used in conjunction with the Land
DPU Power Supply Unit.
To prevent damage to the equipment, ensure that the DPU (power supply)
and signal processor are fully interconnected, before switching on the mains
power supply.
The LMT to DPU wiring interconnections are given in Fig. 5 (overleaf).
The LMT wiring schedule is given in Table 1.
The DPU wiring schedule is given in Table 2.
ConnectionstothecongurationportaregiveninTable3-AppendixB.

3.4 Cable connector assembly
The cable connectors for the processor are included in the processor package.
Each cable connector must be correctly wired with the appropriate cable.
(Refer to Section 3.3 for the cable schedules).
To wire up the connector.
1) Make a note of the connector’s orientation.
2) Unclip the two halves of the connector shell to reveal the terminal block
and the cable tie/clamp bar.
3) Wire up the connector, remembering the correct orientation of the plug,
in accordance with the relevant cable schedule (see Section 3.3).
4) Ensure that the cable outer insulation is held in the clamp bar/cable tie
at the connector and tighten the clamp bar screws/cable tie. Refer to
Fig.8.
5) Clip together the two halves of the connector shell ensuring that the
‘write-on’ label is held in place by the shell assembly.
The connector is now ready for use.
Keep wire length as
short as possible
Ensure cable's outer insulation
is held in clamp bar/cable tie

4 Using the Configurator
When the processor is connected to a System 4 thermometer, the processor
mustbeconguredforusewiththatparticularthermometerandhaveits
operating parameters set. The temperature measurement system (i.e.
processorandthermometer)ismosteasilyconguredusingtheLMTechnic
CongurationSoftwareandasuitablePC.
It is also possible to use a PC running standard terminal software and an
RS232porttoperformtheconguration,allowingtheindividualcommandsto
be used. See Appendix B.
Oncecongured,thePCcanbedisconnectedandtheLMTechniccanbeleft
torunalone,withcongurationstoredintoit’snon-volatilememory.
4.1 Installation
RuntheleontheCDandfollowtheInstallationInstructions.
4.2 Getting Started
After the power supply has been connected (see Section 3) and switched on,
itispossibletoconguretheLMTechnicusingthecongurationsoftware.
ConnecttheconguratorcablebetweenthePCandtheLMTechnicand
runthesoftwarebyrunningthe.exeleintheinstallationdirectory.The
