and High pH value.
16.3 Output setup
Thegeneralprocedureistorstdenethefunctionoftheoutput,OutputorSimulate.Then,set
the process parameters associated with the output. On the Output, an output of measured value
is selected. On the Simulate, a simulation value can be set.
And,theparametersforHOLDfunctioncanbesetonthissetting.
l Output
Theoutputsignalisacurrentvaluespeciedbythefollowingparameters.
Process parameter
The available process parameters depend on the selected “Sensor type” on the Sensor setup
and the selected “Measurement” type on the Measurement setup.
The output of the selected process parameter is shown as a bar on the bottom of the Main
display.Anditsparametersymbol(forexample,PH1)isshownabovethebar,too.When
a selected process parameter is displayed as a measurement value, the top left number or
characteristurnedtobewhitenumberorcharacteronblackbackground(forexample,
). (Refer
to the section 1.2.)
Process parameters can be selected from among:
pH1,Temperature1,andORP1: SENCOMmodule’smeasuredvalues
Setup
Select one of the output methods: Linear and Table.
Linear: Set the 0% and 100% values.
Table: Thisallowsthecongurationofanoutputcurveby21points(5%intervals).
(The 0% and 100% values must be entered.)
Burn
Select the designated output in case of a fault from among Off, Low, and High. See “16.4 Error
conguration”tosettheoutput.
Off: Output depends on the measured value.
Low: Outputisxedto3.6mA
High:Outputisxedto22.0mA.
Damping time
Thisisthetimetakenforaresponsetoastepinputchangetoreach90%ofthenalvalue
(attenuation time). Set this time in sec.
l Simulate
Whenthisfunctionisselected,anoutputoftheinstrumentwillbeaxedcurrentvaluesetin%of
the output span. The output span range is -2.5% to 112.5% (3.6 mA to 22.0 mA).
When “Simulate” is selected, regardless of hold setting, the output is always simulated value.
