Standard functions
EVT1 output
Output is turned ON or OFF depending on the conditions selected in [Event output
allocation].
Output: Relay contact 1a
Control capacity: 3A 250 V AC (resistive load)
1A 250 V AC (inductive load cos =0.4)
Electrical life: 100,000 cycles
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 alarm with standby, Low limit alarm with
standby, 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 ‘12.4 Alarm Action’ on pages 76, 77.
Set value:
Factory default: 0
Setting accuracy : Based on the Base 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 is selected in [Event output allocation]
Loop break alarm
Detects the breaking status on the loop such as heater burnout, sensor burnout or
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 placement
of the decimal point follows the selection.)
Output:
EVT output for which Loop break alarm is selected in [Event output
allocation]
