Alarm Outputs
Each alarm can be independently set to one of the following 13 alarm types. The default is 2: Upper limit.
Auxiliary outputs are allocated for alarms. ON delays and OFF delays (0 to 999 s) can also be specified.
Note: For models with heater burnout, SSR failure, and heater overcurrent detection, alarm 1 will be an OR output of the alarm selected from the
