CHAPTER 5: SETPOINTS
All RTDs programmed with an alarm or a trip are monitored for sensor failure. When the
measured temperature is greater than 250°C, the RTD is declared failed and a common

common RTD short circuit/low temperature alarm is issued.
The following setpoints are available for RTD protection.
RTD Open Circuit Alarm
