Setting Item, Function, Setting Range
Loop break alarm span
• Sets the action span to assess the Loop break alarm.
• Setting range:
Thermocouple, RTD input without decimal point: 0 to 150
( )
Thermocouple, RTD input with decimal point: 0.0 to 150.0
( )
DC voltage, current input: 1 to 1500
(The placement of the decimal point follows
the selection.)
Available when 014 (Loop break alarm output) is selected in [Event output EV2
allocation].
Event output EV3 allocation
• Selects Event output EV3 from the Event Output Allocation Table below.
For Alarm output, the alarm value is set by
deviation from the SV
(excluding Process alarm), and if the input goes outside the range, the Alarm
output is turned ON (turned OFF for High/Low limit range alarm).
When De-energized action is selected, the output is activated conversely.
Pattern end output turns ON after program control ends.
Loop break alarm output turns ON after detecting actuator trouble (heater
burnout, heater adhesion) or sensor burnout.
‘Output during AT’ turns ON during AT.

Turns ON during AT.
When
001 to 012 (Alarm output) is selected, one alarm can be set to one event output.
When 013 to 015 is selected, each output is common to multiple event outputs.
EV3 alarm hysteresis
• Sets EV3 alarm hysteresis.
• Setting range:
Thermocouple, RTD input: 0.1 to 1000.0
( )
DC voltage, current input: 1 to 10000
(The placement of the decimal point
follows the selection.)
Available when 001 to 012 (Alarm output) is selected in [Event output EV3 allocation].
