2.1 Display Functions The inter-active front panel display consists of three rows. The first row is the main display, and the second and third row are sub-display 1 and 2 respectively. Monitor Mode and Status Display Status Display Indicators at the right side of the display will light up to show that recording is in progress (refer to page 2-5), alarms are occuring (refer to page 2-14), keys are locked (refer to page 2-18) and chart needs to be replaced (refer to page 2-19).
2.1 Display Functions Display for Setting the Type of Input, Computation and Recording Conditions Menus for setting each of the following functions will be displayed.
2.2 Measurement Input Functions Input Type DC Voltage Measurements can be done after selecting the measurement range per channel. The minimum range is 20mV, the maximum range is 50V. Resistance Temperature Detector Measurements can be done after selecting the type of resistance temperature detector (RTD) per channel.
2.2 Measurement Input Functions Scan Interval • The duration of time (one scan) in which the measurement of all channels is carried out, is called the scan interval. • This interval can be set to any value from 2 to 60s, and this range is the same for the 10ch, 20ch and 30ch model. A/D Integration Time This instrument measures the input signal after putting it through an A/D converter. In order to minimize the noise imposed on the input signal, specific integration times exist.
2.3 Recording Functions Chart Speed The speed at which the chart moves when performing trend recording can be selected from any value between 1 to 1500mm/h. Two types of chart speeds can be set. When you are not using the Event/Action function, which will be described later on in this manual, chart speed 1 will be valid. When the Event/Action function is being used, you can select whether chart speed 1 will change to speed 2 according to the event status.

2.3 Recording Functions Recording Format You can modify the recording format of measurement values according to your own preferences. The following selections are available. Items common for Analog Trend and Logging mode Printing Channel No. or Tag When printing measurement values, the corresponding channel number or a preset tag can be recorded with it. This selection will also affect the display the same way. The number of characters of a tag which will be printed out, can be selected too.
2.3 Recording Functions Recording Colors The color of trend recordings can be selected per channel. The colors which can be selected are black, purple, red-purple, navy blue, red, blue, brown, green, orange and yellowish green. The recording color of the numerical values in the logging mode is purple only. Recording Interval Recording interval = Scan interval × N where N is an integer satisfying N ≤ 720 / (scan interval × chart speed). 720 is fixed.
2.3 Recording Functions Recording Span The maximum value and the minimum value of the measurement range are decided when setting the type of input. The difference between the minimum value and maximum value which will be recorded within this measurement range, is called the recording span. The value on the left and right side of the recording are called the left span and right span respectively.
2.3 Recording Functions Partially Expanded Recording When carrying out trend recording, partially expanded recording enables you to compress a part of the recording span in order to examine the expanded (other) part of the span in more detail. The left boundary of the recording span being 0%, and the right boundary of the recording span being 100%, a segment of the recording span can be compressed. The following example shows a situation where 25% of the recording span has been compressed.
2.3 Recording Functions List Printout A list printout will show the following items.
2.3 Recording Functions Manual Printout One scan of measurement values of selected channels will be recorded as digital values together with the date and time. This printout can be executed by key operation or by event/action function (refer to page 2-18). Refer to page 2-6, 2-7 for a recording example. Header Printout For the header, you can print as many as 60 characters each on 5 lines (DR130) or as many as 80 characters each on 5 lines (DR231/241) and its recording can be executed by key operation.
2.4 Alarm Function This function will show an alarm on the display or generate an alarm output signal with /A4 or /R1 option when the measurement conditions of a channel exceed/fall below preset values. Up to four alarms can be set for each channel. Type of Alarms Six types of alarms are available, namely high limit alarm, low limit alarm, high limit on rate-ofchange, low limit on rate-of-change, difference high limit and difference low limit.
2.4 Alarm Function Operation Mode Energizing/De-energizing Setting The alarm output relays can be selected to be energized or de-energized on alarm occurrence. Using de-energizing, the alarm output relay will be activated when the power drops in the same way as when an alarm occurs. This setting can be done for each relay individually.
2.4 Alarm Function Recording Alarm Information Analog Trend Mode When an alarm occurs (or releases), the occurrence/release mark, message, channel No. or tag and time of occurrence/release will be printed on the right side of the chart. Logging Mode • If an alarm occurs, the type of alarm will be printed together with the measured value. • If an alarm occurs (or is canceled), the alarm occurrence/cancellation mark, channel No.
2.5 Standard Computation Functions Standard computations such as difference between channels and linear scaling can be set with measurement input settings. A moving average computation is also available. Difference between Channels Linear Scaling This function changes the left and right span of the recording span to left and right scale values which are converted to a different physical quantity. This can be applied to each channel and a different engineering unit can be entered for display and printouts.
2.6 Other Functions Event/Action Function Following the occurrence of an event such as remote control signal (12), alarm, internal switch, chart end signal, timer, match time or key operation, any of the following actions can occur.
2.6 Other Functions External Input/Output Function (Option) Alarm Output When /A4 option is installed ten external output relays (make contact) can be used, whereas with /R1 option is installed, two external output relays (transfer contact) can be used. These relays will be operated when an alarm occurs. For details concerning their settings and their relation with alarms, refer to page 2-15, 2-16.

3.8 Countering Noise Types and Features of Noise Sources Commercial Power Supply It is necessary to consider both 50 and 60Hz as noise components. It is important to note that a power supply line in which a thyristor or inverter is incorporated functions not only as an “energy surplus line”, but also as a “supply surplus line”. Thyristor (SCR) A thyristor is used to control power through ON/OFF modulation of commercial power by controlling the phase angle.
3.8 Countering Noise Voltage waveform 3 Installation and Wiring Current waveform Voltage/current waveforms of an inverter Relay A relay is frequently used to amplify alarm and temperature controller outputs. However, since a counter-electromotive force (counter e.m.f.) is produced by coil inductance when the relay is turned off and the e.m.f. becomes noise, care must be taken. Due to chattering at the relay contact, tens to hundreds of kHz noise occurs mainly in bursts.
3.8 Countering Noise Example of a high-frequency induction furnace * Due to electromagnetic induction, current i flows through the conductor, creating joule heat which heats the furnace. J=i2r Furnace C Φ Inverter power supply (20 to 3500kW) Power supply r i (0.
3.8 Countering Noise In the figure on the previous page, due to common mode voltage ECM, noise currents i1 and i2 flow through the impedance to grounds Z1 and Z2 and coupling impedance Z3, resulting in the generation of normal mode noise ENM between input terminals H and L. Like this, common mode noise is converted to normal mode noise. The amp is equipped with a built-in filter and in case of output EO the normal mode noise will be eliminated.
3.8 Countering Noise Balance each other Input voltage (instantaneous value) DC voltage (average value) integration time Normally, an integration time of 20ms (50Hz) or 16.7ms (60Hz) is selected depending on the commercial power supply frequencies. A 100-ms integration mode is added to the instrument to achieve superior noise rejection. However, when using the 100ms setting, the smallest measurement interval is longer than in case of the 20ms or 16.7ms setting.
3.8 Countering Noise • for input lines: an increase of impedance; Always separate the input line from the noise source lines (power and alarm lines). Step 1 : Install a separator. Separator Signal* lines Power lines Special class 3 ground (10Ω or less) Signal lines* Power lines at least 15 cm Step 3 : Leave a clearance of at least 15 cm between the signal lines and power lines.
3.8 Countering Noise Step 2 : Change the position of the noise source. A) Leakage magnetic flux of transformer: Φ = strong Φ = weak Move the instrument to a location where the influence from magnetic flux is weak. B) Sparks spark strong electromagnetic radiation weak electrogmagnetic radiation Move the instrument to a location where the influence from electromagnetic radiation is weak. • Grounding: a decrease of impedance The grounding method is the point of common mode noise suppression.
3.8 Countering Noise • Shielded and twisted pair (prevention of electromagnetic coupling): an increase of impedance If it is difficult to keep the noise source away from the measuring instrument due to space limitations, the use of a shielded twisted pair is effective. • electrostatic coupling can be completely cut off by shielding; • for a magnetic field, shielding with a magnetic material (iron, permalloy, etc.) can be employed.
3.8 Countering Noise • Insertion of noise filter and noise killer If the influence from noise cannot be eliminated by the methods described before, use noise filter or noise killer. Power line noise rejection Step 1 : Insert an isolation transformer into the power line.
3.8 Countering Noise • Relay noise suppression • To prevent noise and protect the contact, connect the diode to the relay coil terminal directly. Dc external • In addition to the above measure, reduce power supply the rated voltage of the relay circuit as much as possible for higher reliability. • It is necessary to choose a diode that R matches the relay. Generally, a diode whose rated rectifying current is at least three times the current flowing through the relay coil must be used.
