Chapter 1 Functional Description

1.1 Overview of the Recorder

The RD100B Recorder (hereafter referred to as the recorder) can be used to assign DC voltage, 1-5V, thermocouple, RTD, and contact or voltage ON/OFF signal to channels for measurement. The measured results are recorded with pens or dots on a chart paper that is fed at a constant speed. The pen model can record up to 4 channels; the dot model can record up to 6 channels.

RD100B Recorder Recording example (dot model)

Alarms

For each channel, various alarms such as high limit alarm and low limit alarm can be assigned to monitor the measured values. Alarm output relays can be used to output contact signals when alarms occur (/A1, /A2, and /A3 options).

Recording

The measured results are recorded with pens or dots on a chart paper (trend recording). The chart speed can be selected from 5 to 12000 mm/h on the pen model and 1 to 1500 mm/h on the dot model. In addition to trend recording, various types of information can be printed or recorded on the chart paper such as numeric measured values, alarm occurrence/release, and predefined messages. Also, the recorder settings can be printed.

Functional Description

Internal Light

A light is provided for easier viewing of the recording area of the chart paper.

Display

Measured values can be displayed numerically or using bar graphs on the large display. Also, alarm status and chart speed can be displayed.

Communication Function

Using the Ethernet communication interface (/C7 option) or the RS-422A/485 communication interface (/C3 option), the measured values on the recorder can be output to a PC or a PC can be used to control the recorder. This manual does not cover the communication functions. For details on communication functions, see the RD100B/RD1800B Communication Interface User’s Manual on the CD-ROM.

Other Main Functions

The computation function (/M1 option) can be used to perform various computations from four arithmetic operations to statistical calculations on 8 and 12 computation channels on the pen model and dot model, respectively. The computed results can be recorded. The remote control function (/R1 option) can be used to control the start/stop and other operations of the recorder by applying contact signals to the dedicated terminals. The FAIL/chart end detection and output function (/F1 option) can be used to output contact signals when errors are detected on the recorder or when the chart paper runs out.

Number of Measurement Channels and Scan Interval

The recorder samples the input signals on the measurement channels at the scan interval to obtain the measured values.

Model Number of Channels Scan Interval

1-pen model 1 125 ms 2-pen model 2 125 ms 3-pen model 3 125 ms 4-pen model 4 125 ms Dot model 6 1 s

Input Type, Measurable Range, and Computation

The recorder can measure the following types of inputs.

Input Type Measurable Range

DC voltage DC voltage in the range of ±20 mV to ± 50 V 1-5V See “1-5V” below. Thermocouple Temperature range corresponding to each type: R, S, B, K, E, J, T, N, W, L, U,

and WRe

RTD Temperature range corresponding to each type: Pt100Ω and JPt100Ω ON/OFF input Contact input: Open contact is OFF (0). Closed contact is ON (1).

Voltage input: Less than 2.4 V is OFF (0). Greater than or equal to 2.4 V is ON (1)

(However, the scan interval is 2.5 s when the integration time of the A/D converter is 100 ms.)

• 1-5V

1-5V is scaled to values in the appropriate unit to be used as measured values. Also, the low-cut function (input less than 0% is fixed to 0 (scale left value)) can be used.

• Current Input

A shunt resistor is attached to the input terminal. The current signal is converted to a voltage signal and measured. The measurable range is the range equivalent to the “DC voltage” range indicated above after converting the current to the voltage signal.

Note

Three types of shunt resistors (250 Ω, 100 Ω, and 10 Ω) are available for current input (see “Optional Accessories (Sold Separately)” on page v). For example, a 250-Ω shunt resistor is

used to convert the signal to the range of 1 to 5 V for 4 to 20 mA input.

• Range Type, Measurable Range, and Recording Span

Various “range type” are available for the different types of inputs (for example thermocouple R). Each range type has a preset measurable range (0.0 to 1760.0°C for thermocouple R). Measurement can be made by specifying an arbitrary range within the measurable range as the input range. The measured values in the input range are recorded on the chart paper. The range of measured values that are recorded is called the recording span.

1.2 Measuring Input Section

• Delta Computation

The value obtained by subtracting the measured value of another channel (called the reference channel) from the input value of the channel set to delta computation is used as the measured value of that channel. The reference channel must be assigned to a channel whose channel number is less than that of the channel on which delta computation is specified. The channel on which delta computation is specified is automatically set to the same range type as the reference channel.

• Square Root Computation

When the input type is DC voltage, the square root of the input value is calculated, the result is scaled to a value in the appropriate unit, and used as the measured value of the channel. Also, the low-cut function (input less than a given measured value is fixed to 0 (scale left value)) can be used.

Burnout Detection of Thermocouples

This function makes the recording go off the scale to the right or left when the thermocouple burns out while measuring temperature with a thermocouple. This function can also be used on 1-5V. The burnout detection function can be set for each channel. By default, this function is disabled.

Note

For 1-5V, a burnout occurs when the input value is less than or equal to 0.2 V.

Setting the burnout detection function: Section 7.3

Reference Junction Compensation of Thermocouple Input

When measuring the temperature using a thermocouple, the reference junction compensation on the recorder can be used. When using external reference junction compensation, you can set the reference voltage. The reference junction compensation can be set for each channel. By default, the recorder is configured to use the internal reference junction compensation function.

Note

When using external reference junction compensation, set an appropriate reference junction

compensation voltage. For example, if the reference junction temperature of the external

reference compensation is T0 °C, set the reference compensation junction voltage to the

thermoelectromotive force of the 0°C reference of T0 °C.

Noise Elimination from Input Signals

Filter and Moving Average

This function used to suppress the effects of noise that is riding on the signal. The pen model and dot model are equipped with a filter function and a moving average function, respectively. The function can be set for each measurement channel. However, it does not operate on channels set to ON/OFF input.

• Filter (Pen Model)

The filter is a low-pass filter. The time constant can be set to 2 s, 5 s, or 10 s.

Input

2, 5, 10 s (time constant, the time it takes to reach 63.2% of the output value)

• Moving Average (Dot Model)

The average value of the m most recent values acquired at the scan interval is used as the measured value of the channel. The number of moving-averaged data points (m) can be set in the range 2 to 16. The figure below shows an example indicating the operation of the buffer for the moving average computation when the number of moving averaged data points is set to 5.

1.2 Measuring Input Section

Integration Time of the A/D Converter

The recorder uses an A/D converter to convert the sampled analog signal to a digital signal. By setting the integration time of the A/D converter to match the time period corresponding to one cycle of the power supply or an integer multiple of one cycle, the power supply frequency noise can be effectively suppressed. The integration time of the A/D converter is selected according to the model from the table below.

Model Integration Time of the A/D Converter

Pen model Select 16.7 ms (60 Hz), 20 ms (50 Hz), or Auto

Dot model Select 16.7 ms (60 Hz), 20 ms (50 Hz), 100 ms or Auto

• If Auto is selected, the recorder detects the power supply frequency and automatically selects 16.7 ms or 20 ms.

• Because 100 ms is an integer multiple of 16.7 ms and 20 ms, this setting can be used to suppress the power frequency noise for either frequency, 50 Hz or 60 Hz.

• The scan interval on the dot model is 1 s when the integration time is set to 16.7 ms or 20 ms and 2.5 s when the integration time is set to 100 ms.

Setting the A/D integration time: Section 7.2

1.3 Alarms

This function generates an alarm when the measured data meets a certain condition. The alarm occurrence/release can be recorded on the chart paper. The alarm status can be displayed on the screen. Also, alarm output relays can be used to output contact signals when alarms occur (/A1, /A2, and /A3 options).

1.3 Alarms

• Delay High Limit Alarm (T)

An alarm occurs when the measured value remains above the alarm value for a specified time period (alarm delay period).

• Delay Low Limit Alarm (t)

An alarm occurs when the measured value remains below the alarm value for a specified time period (alarm delay period).

• Alarm does not occur at T1, because the time period is shorter than the specified

alarm delay period (T).

• The measured value exceeds the alarm value at time X2, and the alarm occurs at

time X3 at which the specified alarm delay period elapses (the time when the alarm occurs is the time at X3).

• The measured value falls below the alarm value at time X4, and the alarm is

released.

Note

• The alarm detection operation is reset when a power failure occurs. The operation

restarts after the power recovers.

• If the alarm value is changed while a delay alarm is occurring, the alarm is released if the

new alarm value does not meet the alarm condition.

Alarm Hysteresis

Hysteresis can be specified to the values for activating and releasing the alarm. The hysteresis applies only to high limit alarm (H) and low limit alarm (L). The hysteresis width can be set in the range of 0.0% (Off) to 1.0% of the recording span in 0.1 steps. The setting applies to all high limit alarms and low limit alarms. By default, the hysteresis width is set to 0.5%.

Functional Description

Alarm Output Relay (/A1, /A2, and /A3 Options)

Contact signals can be generated from alarm output relays when alarms occur. The number of output relays is 2 (/A1), 4 (/A2), or 6 (/A3). The alarm output relays are denoted as I01 to I06 on the recorder. The following functions can be assigned to the alarm output relay.

Diagnosis Output

The diagnosis output can be assigned to alarm output relay I01. The relay is activated when there is an error in the plotter operation on the pen model, when a burnout is detected, or when there is an error in the A/D converter. Output relay I01 is normally energized and de-energizes when an error is detected (de-energized operation and non-hold operation).

Trend Recording

The measured values are printed within a width of 100 mm.

Recording Method (Pen Model)

• The measured value is updated every scan interval and continuously recorded.

• The recording colors in order from channel 01 are red, green, blue, and violet.

Recording Method (Dot Model)

• The most recent measured value is recorded with a dot every dot printing interval. The dot printing interval is in the range of 10 s to 90 s. There are two recording methods from which you can select. One method automatically adjusts the dot printing interval according to the chart speed so that the dots do not overlap. The other method records at the fastest dot printing interval at all times.

• The recording colors in order from channel 01 are purple, red, green, blue, brown, and black. The recording color of each channel can be changed among these six colors.

• For each channel, trend recording can be enabled or disabled.
