3.6 RotatingTransmitterSection
Thetransmittersectioncanberotatedapproximately
360°(180°toeitherdirectionor360°toonedirection
fromtheoriginalpositionatshipment,dependingonthe
congurationoftheinstrument.)Itcanbexedatany
anglewithinaboverange.
1)Removethetwosetscrewsthatfastenthetransmitter
sectionandcapsuleassembly,usingtheAllen
wrench.
2)Rotatethetransmittersectionslowlyandstopitat
designatedposition.
3)Tightenthetwosetscrewstoatorqueof1.5N·m.
IMPORTANT
Donotrotatethetransmittersectionmorethanthe
abovelimit.

TheterminalboxcoverislockedbyanAllenhead
bolt(ashroudingbolt)onATEXameprooftype
transmitters.Whentheshroudingboltisdriven
clockwisebyanAllenwrench,itisgoinginandcover
lockisreleased,andthenthecovercanbeopened.
Whenacoveriscloseditshouldbelockedbya
shroudingboltwithoutfail.Tightentheshroudingbolt
toatorqueof0.7N·m.
1) Removethecover.
2) Whilesupportingtheintegralindicatorwithonehand,
loosenitstwomountingscrews.
3) DismounttheLCDboardassemblyfromtheCPU
assembly.Whendoingthis,carefullypulltheLCD
boardassemblystraightforwardsoasnottodamage
theconnectorpinsbetweenitandtheCPUassembly.
4) AfterrotatingtheLCD,alignboththeLCDboard
assemblyandCPUassemblyconnectorsandengage
them.
