A1 output
When A1 action is set as Energized, the alarm action point is set by
deviation
from the SV (except Process alarm).
When the input is out of the range, the output turns ON or OFF (in the case of
High/Low limit range alarm).
When the alarm action is set as Deenergized, the output acts conversely.
Setting accuracy : The same as the Indication accuracy
Action
: ON/OFF action
Hysteresis
: Thermocouple, RTD input, 0.1 to 100.0
( )

Control action
• PID action (with auto-tuning function)
• PI action: When derivative time is set to 0
• PD action (with auto-reset function): When integral time is set to 0
• P action (with auto-reset function): When integral and derivative times are set to 0
