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 following alarm types and the alarms for heater burnout, SSR failure, and heater
          overcurrent. To output only a heater burnout alarm, SSR failure alarm, and heater overcurrent alarm for alarm 1,
          set the alarm type to 0 (i.e., no alarm function).
