For conguration 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 inuence 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 50- and 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 conguration 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 Cu25,3and 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 input4You 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 conguration 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.

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 conguration 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 conguration 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.
For conguration instructions, see Section 3.5.

• Reflash
This function enables a single alarm output relay with multiple alarms assigned to it to
indicate all alarm occurrences. After the rst alarm, subsequent alarms are indicated
by the brief release (approximately 500 ms) of the output relay.
The reash function affects the rst 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).

Internal switches can be used as events with the event action function (for details, see

/PM1 options) expressions.
