Alarm standby function
When the power supply to the instrument is turned on, even if the input enters the alarm action
range, the alarm is not activated.
Even if the alarm action point enters the alarm action range due to the SV being changed while the
controller is running, the alarm is not activated, either.
Once the input exceeds the alarm action point, the standby function is released, ensuring the
controller continues to run.
"A1" means Alarm 1. For Alarm 2, read "A2" for "A1".
EVT1 indicator is for Alarm 1, and EVT2 indicator is for Alarm 2.
Terminals 3 & 4 are for the user's own Alarm 1 indicator, which correlates directly with the EVT1 indicator.
Terminals 5 & 6 are for the user's own Alarm 2 (or Heater burnout alarm output) indicator, which correlates
directly with the EVT2 indicator.
