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
