DYNAPAR brand PRODUCT MANUAL: Series S428A 1/8 DIN Process IndicatorNoise Suppression at SourceUsually when good wiring practices arefollowed, no further noise protection isnecessary. Sometimes in severe electricalenvironments, the amount of noise is sogreat that it has to be suppressed atsource. Many manufacturers of relays,contactors etc supply ‘surge suppressors’which mount on the noise source. Forthose devices that do not have surge suppressorssupplied, Resistance-Capacitance(RC) networks and/or Metal Oxide Varistors(MOV) may be added.Contacts:- Arcing may occur across contactswhen they open and close. This resultsin electrical noise as well as damageto the contacts. Connecting a properlysized RC network can eliminate this arc.For circuits up to 3 amps, a combination ofa 47 ohm resistor and 0.1 microfarad capacitor(1000 volts) is recommended. Forcircuits from 3 to 5 amps, connect two ofthese in parallel.Inductive coils:- MOVs are recommendedfor transient suppression in inductive coils,connected in parallel and as close as possibleto the coil. Additional protection may beprovided by adding an RC network acrossthe MOV.Contact noise suppressionTransient Suppression with Inductive Coils2.04Manual Number: 702683-0001 Rev.: A August, 2006 Installation

DYNAPAR brand PRODUCT MANUAL: Series S428A 1/8 DIN Process IndicatorSensor Placement (Thermocoupleor RTD)If the temperature probe is to be subjectedto corrosive or abrasive conditions, it mustbe protected by an appropriate thermowell.The probe must be positioned to reflect trueprocess temperature:1. In a liquid media - the most agitated area2. In air - the best circulated areaCAUTION:The placement of probes into pipework some distance from the heatingvessel leads to transport delay, whichresults in poor control.Thermocouple Wire IdentificationChartThe different thermocouple types are identifiedby their wire colors, and where possible,the outer insulation (sheath) as well.There are several standards in use throughoutthe world.+ Wire SheathThe table below shows the wire and sheathcolors used for most common thermocoupletypes. The format used in the table is:+ Wire Color- Wire ColorSheathColorFor a two wire RTD a wire link should beused in place of the third wire.

Its value may be adjustedbetween Scale Range Upper Limit and Scale Range Lower Limit.Display code = pla1, Default value = Scale Range Lower Limit. Also refer to Alarm Operation,Process Low Alarm 2 Value, Process Variable, Scale Range Lower Limit and ScaleRange Upper Limit.Process Low Alarm 2 ValueType: General ParameterThis parameter, applicable only when Alarm 2 is selected to be a Process low alarm. It issimilar to the Process Low Alarm 1 Value. Display code = pla2, default value = ScaleRange Lower Limit.Also refer to Alarm Operation, Process Low Alarm 1 Value, Process Variable, Scale RangeLower Limit and Scale Range Upper Limit.Process Variable (PV)Type: General DefinitionProcess Variable is the variable to be measured by the primary input of the instrument. ThePV can be any parameter that can be converted into a electronic signal suitable for theinput. Common types are Thermocouple or PT100 temperature probes, or pressure, level,flow etc from transducers which convert these parameters into linear DC signals (e.g. 4 to20mA). Linear signals can be scaled into engineering units using the Scale Range LowerLimit and Scale Range Upper Limit parameters.Also refer to Input Span, Scale Range Lower Limit and Scale Range Upper Limit.Retransmit OutputType: General DefinitionA linear DC voltage or mA output signal, proportional to the Process Variable for use byslave controllers or external devices, such as a Data Recorder or PLC. The output can bescaled to transmit any portion of the input span.Also refer to Input Span and Process Variable.Retransmit Output 1 Scale MaximumType: General ParameterScales a linear output module in slot 1 that has been set up to retransmit PV. RetransmitScale Maximum defines the value of the process variable at which the output will be at itsmaximum value. E.g. for a 0 to 5V output, the value corresponds to 5V. It may be adjustedwithin the range -1999 to 9999; the decimal position is always the same as that for theprocess variable input. If this parameter is set to a value less than that for RetransmitOutput 1 Scale Minimum, the relationship between the process variable and theretransmission output is reversed. Display code = roiK, default value = Scale RangeUpper Limit.Also refer to Process Variable, Retransmit Output, Retransmit Output 1 Scale Minimumand Scale Range Upper Limit.A2.06Manual Number: 702683-0001 Rev.: A August, 2006 Appendix 2

GlossaryTareType: Indicator ParameterWhen an Indicator’s Tare function has been enabled, the operator can set the currentProcess Variable input value to be displayed as zero. This function may be used to easilyeliminate any offset on the input signal, e.g. when a transducer output is not giving a truezero value. It may also be used in applications displaying the weight of a product, to removethe weight of a container before starting. When Tare is activated, the instrumentautomatically sets the PV Offset to an equal, but opposite value to the current measuredvalue.Display code = tare, default setting = disa (disabled).Also refer to Indicator and Process Variable.TriacType: General DefinitionA small internal solid state device, which can be used in place of a mechanical relay inapplications switching low power AC, up to 1 amp.
