Alarm Types
The CLS has three different kinds of alarms: failed sensor alarms,
global alarms, and process alarms.
Failed Sensor Alarms
Failed sensor alarms alert you to T/C breaks and these RTD open or
short failures:
• Open + input.
• Open - input.
• Short between + and - input.
Failed sensor alarms alert you to T/C breaks. When the loop is in
Automatic or Tune mode and a failed sensor alarm occurs, the CLS sets
the loop to Manual control at the output override percentage you set in
the Set up Loop Outputs menus.
