signal and sensor error indication without display front
Status.of.the.unit.can.also.be.read.from.the.red/green.LED.in.the.front.of.the.device..
Green.flashing.LED.13.Hz.indicates.normal.operation..
Green.flashing.LED.1.Hz.indicates.sensor.error..
Steady.green.LED.indicates.internal.error..
Steady.red.LED.indicates.fatal.error.
advanced functions
The.unit.gives.access.to.a.number.of.advanced.functions.which.can.be.reached.
by.answering.“Yes”.to.the.point.“adv.set”.
display setup:.Here.you.can.adjust.the.brightness.contrast.and.the.backlight..
Setup.of.TAG.number.with.6.alphanumerics..Selection.of.functional.readout.
in.line.3.of.the.display.-.choose.between.readout.of.analogue.output.or.TAG.
number.
Two-point process calibration:.The.unit.can.be.process-calibrated.in.2.points.
to.fit.a.given.input.signal..A.low.input.signal.(not.necessarily.0%).is.applied.
and.the.actual.value.is.entered.via.4501..Then.a.high.signal.(not.necessarily.
100%).is.applied.and.the.actual.value.is.entered.via.4501..If.you.accept.to.
use.the.calibration,.the.unit.will.work.according.to.this.new.adjustment..If.you.
later.reject.this.menu.point.or.choose.another.type.of.input.signal.the.unit.will.
return.to.factory.calibration.
Process simulation function:.If.you.say.”yes”.to.the.point.“EN.SIM”.it.is.
possible.to.simulate.an.input.signal.by.means.of.the.arrow.keys.and.thus.
control.the.output.signal.up.or.down..When.you.finalise.the.point.with.
3
,.the.
unit.returns.to.normal.mode.
Password:.Here.you.can.choose.a.password.between.0000.and.9999.in.order.
to.protect.the.unit.against.unauthorised.modifications.to.the.configuration..
The.unit.is.delivered.default.without.password..If.you.have.locked.the.unit.
with.a.password.by.mistake,.you.can.always.open.the.menu.by.using.the.
master.password.2008.
language:.In.the.menu.”lang.setup”.you.can.choose.between.7.different.
language.versions.of.help.texts.that.will.appear.in.the.menu..You.can.choose.
between.UK,.DE,.FR,.IT,.ES,.SE.and.DK.
auto diagnosis
The.unit.performs.an.advanced.auto.diagnosis.of.the.internal.circuits..
The.following.possible.errors.can.by.display.in.the.front.unit.4501..
CJ.ER. -. CJC.sensor.defect.or.CJC.temperature.outside.range.
FL.ER. -. Flash.error.
AO.ER. -. No.load.on.the.current.output.(only.for.S4...20.mA/S20...4.mA).
NO.CO. -. Connection.error.
IN.ER. -. Error.levels.on.input.
TY.ER. -. Configuration.in.4501.does.not.match.this.product.type
selection of units
After.choosing.the.input.signal.type.you.can.choose.the.process.units.which.
will.be.displayed.in.text.line.2.(see.table)..By.selection.of.temperature.input.
the.process.value.is.always.displayed.in.Celsius.or.Fahrenheit..This.is.
selected.in.the.menu.point.after.selection.of.temperature.input.
safety readback
When.the.device.is.delivered.with.default.configuration,.the.SIL.function.is.
disabled..The.safety.readback.function.(loop.surveillance).can.be.selected.in.
the.menu.O.RANGE,.thus.enabling.the.device.to.run.in.SIL.mode..In.order.
to.enable.the.SIL.functionality,.the.menu.item.S4...20.mA.must.be.selected..
Please.note,.however,.that.when.safety.readback.is.enabled,.a.sensor.error.
will.be.indicated.as.an.error.on.the.analogue.output.signal.
CjC
In.the.CJC.menu.you.can.choose.between.external.CJC.connector.and.internal.
cold.junction.compensation..The.external.CJC.connector.(PR.5910).must.be.
ordered.separately.
Memory
In.the.memory.menu.you.can.save.the.configuration.of.the.device.in.the.4501,.
and.then.move.the.4501.onto.another.device.of.the.same.type.and.download.
the.configuration.in.the.new.device.
