Alarms Chapter 5 Alarm & Error Codes Using Alarms The Series 733/734 has two alarm types, Process or Deviation. A Process alarm sets an absolute temperature. When the process exceeds that absolute temperature limit an alarm occurs. The Process alarm set points may be independently set high and low. A Deviation alarm alerts the operator when the process strays too far from set point. The operator can enter independent high and low alarm settings. The set point is the reference for the deviation alarm.
