EVT output
•
Alarm output [Common output with Loop break alarm and Heater burnout alarm (option)]
The alarm action point is set by ± deviation to the main setting (excluding Process alarm) and when
input exceeds the range, alarm (EVT) is turned ON or OFF (High/Low limit range alarm).
When Deenergized is selected during the Energized/Deenergized selection, alarm (EVT) is activated
conversely.
Setting accuracy
: The same as indication accuracy
Action : ON/OFF action
Hysteresis : Thermocouple and RTD inputs : 0.1 … 100.0°C (°F)
DC voltage and current inputs : 1 … 1000 (The placement of the
decimal point follows the selection)
Output : Open collector, Control capacity 24V DC 0.1A (Max.)
Alarm output action : One alarm action is selectable from below by front key operation:
High limit, Low limit, High/Low limits, High/Low limit range, Process high,
Process low, High limit with standby, Low limit with standby,
High/Low limits with standby and No alarm action.
Energized/Deenergized : Alarm (EVT) output Energized/Deenergized can be selected.
Energized Deenergized
Red (EVT) LED Lights Lights
EVT output ON OFF
Alarm HOLD function selection : Once the alarm is activated, alarm output is held until
the power is turned off.
•
Loop break alarm output (Common output with Alarm and Heater burnout alarm [Option])
Detects heater burnout, sensor burnout and actuator trouble.
Setting range:
time setting : 0 … 200 minutes
span setting : 0 … 150°C (°F) or 0.0 … 150.0°C (°F)
DC voltage and current inputs: 0 … 1500
(the placement of the decimal point follows the selection)
Output : Open collector
control capacity 24V DC 0.1A (max.)
