Note
• When setting alarm values in continuous channels, use the decimal point as follows:
The decimal point of an alarm value when the continuous channels have different measuring
ranges should be in the position determined by the individual measuring range. If the
decimal point is outside the measuring range, an error occurs. For example, if channels
with measuring ranges 20 mV and 2 V, and a type T thermocouple channel, are all set to an
alarm value of 10000, then the alarm values in the respective channels are as follows:
10.000 mV in the 20 mV measuring range channel
1.0000 V in 2 V measuring range channel
1000.0°C in the type T thermocouple channel
• A type T thermocouple has a measuring range from –200.0 to 400.0°C, so an error results.
• If you make below changes, channel alarm values will also change automatically:
• Recording span.
• Linear scaling settings.
• Power monitor channel wiring and input range.
Setting Relays (Internal Switches)
Set which alarm output relay or internal switch should be triggered when an alarm
occurs:
• Select the desired alarm output relay or internal switch from among the following. The
default setting is OFF.
• OFF : Alarm output relays and internal switches remain OFF.
• S01 to S60 : 60 internal switches are provided.
• UMN
U : Unit number for an alarm module or a DI/DO module. M: Slot number for an
alarm module or a DI/DO module. N: Number 0 to 9. For details, see page
3-8.
• Multiple alarm setpoints can be set for one alarm output relay or internal switch.
• The operation mode in the alarm output relay or internal switch can be set when
an alarm occurs. For details, see Section 4.21, “Setting Relay and Internal Switch
Actions.”
• When the alarm module or DI/DO module is not recognized as system module, the
relay is set to OFF.
Selecting the Alarm Printout (DR only)
This setting can be selected from the following. The default setting is ON2.
OFF: Alarm printout will not be carried out;
ON1: Alarms will only be printed out on occurrence.
The alarm occurrence mark, channel No. or tag, type of alarm, alarm heading or time of
occurrence will be printed with trend recordings.
ON2: Alarms will both be printed out on occurrence and release.
The alarm occurrence/release mark, channel No. or tag, type of alarm, alarm heading or
time of occurrence/release will be printed with trend recordings.
Selecting a Message Printout (DR only)
This setting specifies whether to print a message on alarm occurrence, and if so, which
message will be printed. The default setting is OFF.
OFF: No message will be printed.
