Temperature
Use the temperature alarm to activate an alarm when the temperature reaches the ON
setpoint (2.8.1.5.) (Page 197). This alarm uses the same setpoint parameters as the level
alarms [ON Setpoint (2.8.1.5.) (Page 197) and OFF Setpoint (2.8.1.6.) (Page 197) ]
You can set a high alarm (ON Setpoint > OFF Setpoint) or a low alarm (ON Setpoint < OFF
Setpoint).
This shows a high alarm:
