Alarm action
When Alarm action (Energized) is selected in [Event output
allocation], the alarm action point is set by the deviation from the
SV (except Process alarm).
When the input goes outside the range, the output turns ON or OFF
(in the case of High/Low limit range alarm).
When the alarm action is set as De-energized, the output acts
conversely.
Types: High limit alarm, Low limit alarm, High/Low limits alarm,
High/Low limits independent, High/Low limit range, High/Low limit
range independent, Process high alarm, Process low alarm, High
limit with standby alarm, Low limit with standby alarm, High/Low
limits with standby, High/Low limits with standby independent
Energized/De-energized action are applied to the above alarms,
totaling 24 alarm types. No event can also be selected.
(Factory default: No event)
Refer to Section ‘11.3 Alarm action’ (pp. 83, 84)
Set value
Factory default: 0
Setting
accuracy
Based on the Indication accuracy and Cold
junction temperature compensation accuracy.
Action
ON/OFF action
Hysteresis:
Thermocouple, RTD inputs: 0.1 to 1000.0 ( )
(Factory default: 1.0 )
DC voltage, current inputs: 1 to 10000 (The
placement of the decimal point follows the selection.)
Output
EVT output for which Alarm output is selected in
[Event output allocation].
Loop break
alarm
Detects heater burnout, sensor burnout and actuator trouble.
Setting
range
Loop break alarm time: 0 to 200 minutes
Loop break alarm band: 0 to 150 ( ),
0.0 to 150.0 ( ),
DC voltage, current inputs: 0 to 1500 (The place-
ment of the decimal point follows the selection.)
Output
EVT output for which Loop break alarm is
selected in [Event output allocation].
Attached functions
Sensor correction
Corrects sensor input value.
Set value lock
Lock 1, Lock 2, Lock 3, Lock 4
Auto/Manual
control switching
Auto/Manual control can be switched using the
key in PV/SV
Display Mode.
Program
control function
Number of steps: 15
Program control starts or stops with the
key. If Pattern end
output is selected in [Event output allocation] (pp. 34-36), the Event
output to which Pattern end output is allocated is turned ON when
program is finished. If the
key is pressed for 1 second while
program is operational, the Advance function initiates, interrupting
the performing step, and proceeds to the next step.
Power restore
action
Selects program status when power failure occurs during program
control RUN and is restored.
Progressing time error after power is restored: 1 minute
