Measurement Channels

•Number of Channels vs. Scan Interval

The MV acquires data by sampling measurement channel input signals at the set scan interval. The following is a list of the scan intervals available with different numbers of channels.

	Number of		Scan Interval
Model	Measurement	Normal Mode		Fast Sampling Mode
	Channels
MV1004	4	125 ms, 250 ms		25 ms

MV2020	20
MV2030	30	1 s, 2 s, 5 s	2 s, 5 s	125 ms
MV2040	40
MV2048	48
A/D converter integration time		60 Hz/50 Hz	100 ms	600 Hz (fixed)

For configuration instructions, see section 3.1.

•A/D Converter Integration Time

The MV uses an A/D converter to convert sampled analog signals to digital signals.

You can effectively eliminate the influence of power supply noise by setting the A/D converter’s integration time to the same length as or to an integral multiple of the power source period.

•Because 100 ms is an integral multiple of both 16.7 ms and 20 ms, you can effectively eliminate the influence of power supply noise from both 50and 60-Hz frequencies by setting the integration time to 100 ms.

•Power supply noise elimination is less effective in fast sampling mode than it is in normal mode. When measuring in an environment susceptible to power supply noise, we recommend that you measure in normal mode.

For configuration instructions, see section 3.1.

Input Types and Computation Functions

You can measure the following types of input.

Input Type	Description
DC voltage	You can measure DC voltages in the range of ±20 mV to ±50 V.
DC current	You can measure a DC current signal by converting it to a voltage signal using a shunt
	resistor attached to the input terminal.1
	The converted signal can be measured within the DC voltage range (see above).
Thermocouple	You can measure temperatures using these thermocouple types: R, S, B, K, E, J, T, N,
	W, L, U, and WRe3-25. It is also possible to measure using other thermocouples, such as
	PR40-20 and PLATINEL.2
RTD	You can measure temperatures using RTD types Pt100 and JPt100. It is also possible to
	measure using other RTD types such as Cu10 and Cu25,3 and Pt50 and Ni100.2
ON/OFF input	You can display contact input or voltage input signals correlated to 0% or 100% of the
	display range.
	Contact input: A closed contact is ON (1). An open contact is OFF (0).
	Voltage input: Less than 2.4 V is OFF (0). 2.4 V or more is ON (1).
Pulse input4	You can count pulses.

1 Shunt resistor sold separately. For example, you can use a 250-Ω shunt resistor to convert a 4- to 20-mA signal to a 1- to 5-V signal.

Note

You can use difference computation even if the reference channel and difference computation channel’s input types and ranges are different. Difference computation takes place using the difference computation channel’s decimal place and unit.

Example 1: If the input value of the difference computation channel is 10.00 and the measured value of the reference channel is 100.0, the result is 10.00–100.0=–90.00.

Example 2: If the input value of the difference computation channel is 10.00 V and the measured value of the reference channel is 5.00 mV, the computed result is 10.00 V – 5.00 mV = 5.00 V.

•Hysteresis

You can set a difference between the value that activates an alarm and the value that deactivates it.

For configuration instructions, see section 3.5.

•Delay High Limit Alarm and Delay Low Limit Alarm

If the measured value remains above or below the set alarm value for the set period of time (the delay time), an alarm is activated.

•High Limit on Rate-of-Change Alarm and Low Limit on Rate-of-Change

Alarm

The MV checks the rate-of-change of the measured values over a set period of time (the interval) and activates an alarm if the rate-of-change in the rising or falling direction is greater than or equal to the set value.

The alarm value of the rate-of-change alarm is set using an absolute value. The interval is derived from the sampling count using the following equation:

Interval = scan interval × sampling count

For instructions on how to set the interval, see section 3.5.

•Difference High Limit Alarm and Difference Low Limit Alarm

The MV activates an alarm when the difference between the values of two channels goes above or below the set value. You can use this alarm on measurement channels set to difference computation.

1.3 Alarms

Alarm display

Alarm conditions are indicated in operation windows (trend, digital, bar graph, overview, etc.) and by icons in the status display section. The alarm summary displays detailed alarm information.

•Hold/Nonhold of Indication

When alarm conditions cease, their indicators can be set to either:

•Stop as soon as the alarm condition ceases (Nonhold).

•Continue until the execution of an alarm output release (AlarmACK) operation (Hold). The default setting is Nonhold.

For configuration instructions, see Section 3.5.

•Alarm Hide Function

If this function is enabled, the MV will not display alarm condition information or record it in the alarm summary. However, the MV will output alarm information to a relay (/A options) or internal switch. You can set this function for each channel and alarm.

For configuration instructions, see Section 3.6.

Alarm Output Relay Operation

The MV can generate a contact signal from an alarm output relay (/A options) when an alarm occurs. The alarm output relay operation can be changed.

1.3 Alarms

•Reflash

This function enables a single alarm output relay with multiple alarms assigned to it to indicate all alarm occurrences. After the first alarm, subsequent alarms are indicated by the brief release (approximately 500 ms) of the output relay.

The reflash function affects the first three output relays.*

*I01 to I03 or I11 to I13. With the /A1 option, I01 and I02.

Note

When reflash is enabled, the first three output relays are used exclusively as reflash relays.

The first three output relays are set to OR logic and to the Nonhold operation regardless of the

AND/OR or Nonhold/Hold settings explained below.

•AND/OR

When multiple alarms are assigned to one output relay, you can choose to activate the alarm in one of the following ways (you can also use AND/OR with internal switches):

•AND: Activate the relay when all of the alarms assigned to it occur simultaneously.

•OR: Activate the relay when any of the alarms assigned to it occur.

•Energize or De-energize Operation

You can choose whether to energize or de-energize alarm output relays when an alarm occurs. If you select de-energize, the alarm output relays will be in the same state when the power is shut off as they are when an alarm occurs. This setting applies to all alarm output relays.

•Nonhold/Hold

When an alarm condition is no longer met, alarm relays can be set to:

•Turn OFF immediately (Nonhold).

•Remain ON until the execution of an alarm output release (AlarmACK) operation (Hold). This setting applies to all alarm output relays.

•Alarm Output Release Operation

The alarm output release operation (AlarmACK) stops the display and the relay output of all alarms. For information about how alarm display and output relay operations respond to an AlarmACK operation, see the previous page.

Note

When you enter Basic Setting Mode, the alarm output relay remains at its current active/ released state. In Basic Setting Mode, alarms are not detected and the AlarmACK operation is invalid.

Internal Switch

The MV can transmit the alarm status to software switches (30 internal switches). Internal switch values are shown below. As with AlarmACK, you can apply an AND or OR operation (see the previous page).

	Alarm occurrence
Alarm
			Alarm release
	1
Internal switch
	0

Internal switches can be used as events with the event action function (for details, see section 1.7). Internal switches can also be written into computation channel (/M1 and /PM1 options) expressions.

•Waveform Updating

Every 30 dots makes up one division (also referred to as DIV) on the time axis. The waveform update interval is the time corresponding to one dot. The time

corresponding to one dot depends on the time set to one division (the trend interval). The relationship between the trend interval and the speed of waveform movement in the display is as follows:

Trend interval (per DIV)	5 s1	10 s1	15 s2	30 s	1 min
Time corresponding to one dot (in seconds)	0.125	0.25	0.5	1	2
Speed of waveform movement (approximation in mm/h)	10000	5000	2500	1250	625

•Measurement Channel Numeric Value Display

When the MV detects a range-out (see below), the display is either “+Over” or “-Over.” When the MV detects a burnout on a channel that has been set to be checked for burnouts, the display is “Burnout”. All other values are displayed numerically.

Range-outs are detected on measurement channels in the following circumstances.

•If the DC voltage input value goes above the measurable range ± 5%, a range-out is detected. For example, when the measurement range is 2 V, the measurable range is –2.000 to 2.000 V. If the voltage exceeds 2.200 V, a positive range-out is detected. If it goes below –2.200 V, a negative range-out is detected.

•If the input type is thermocouple or RTD, a range-out is detected when the temperature goes 10°C above or below the measurable range. For example, when the measurement range is set to R, the measurable range is 0.0 to 1760.0°C. If the temperature exceeds 1770.0°C, “+Over” will be displayed. If the temperature goes below -10.0°C, “-Over” will be displayed.

•On channels that use linear scaling, the range-out values, ignoring the decimal point, are above 30000 and below –30000. However, you can also set the range-out values to 105% or greater, and –5% or less of the scale width, as long as those values fall within ±30000.

For configuration instructions, see section 3.11.

•Computation Channel Numeric Value Display

See section 1.9.

•External Input Channel Numeric Value Display (/MC1 option)

The range of displayable values, ignoring the decimal point, is –30000 to 30000. The decimal place is determined by the location of the decimal point on the external input channel’s minimum span value. Regardless of maximum and minimum span value settings, all values within the range of –30000 to 30000 will be displayed. If the value exceeds 30000, “+Over” will be displayed. If the value goes below –30000, “-Over” will be displayed.
