Technical description
The alarm unitM2118 isused tocheckorcontrolanytype ofsignalcurrentorvoltagesignal.It converts
the inputsignaltoan internalstandardsignalofforexample0to100.0%.Inthisrangetwoalarm
contactscan be setindependently.A4-digitLED displayshowsthe actualvalue and setpointsoralarm
values inthe rangeof-1999 to9999 units.
All settingsas alarm values,hysteresis,rangeand operatingmode ofthe floatingcontactscan be set
withalinkcable, connected toapersonalcomputer or alaptop.
Bothalarm contactscan also be programmed withtinypush button switches behind the front panel.
Atypicalapplication wouldbe tomeasureand monitorpressureinaprocess vessel.The pressure
transmitterconvertsthe pressureof1to10 bartoacurrentsignalof4to.20mA.The M2118 monitors
under- and overpressureinthe vessel.It convertsthe 4... 20mAsignalcurrentto0...100.0%.The alarm
issetbetween 0%(=1bar) and 100.0%(=10 bar). Withthese floatingalarm contacts,overpressure
valves, compressors, etc. aredriven directly.
Optionally, agalvanicisolated output signalof0...20mAor 4...20mAisavailable.

I. General references forusing theprogramming software
-The newest software maybe downloaded anytime and free ofchange at www.mostec.ch.
-Connect the M2118 to the powersupplyforprogramming
-Be sure that the connected COM-port isn`t used byanyotherperipherialdevice.
-Ifthe PC orthe corresponding COM-port is"grounded"bythe powerline cable orbyothercabeling, ground
loopsmayinterfere with the measuring signal. The use ofa computerwith batterypowerisrecommended to
avoid such problems.
-Contact usifthere are problemsorquestionsconcerning the software.
