Alarm Outputs
Each alarm can be independently set to one of the following 15 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).
✽1.With set values 1, 4 and 5, the upper and lower limit values can be
set independently for each alarm type, and are expressed as “L”
and “H.”
✽2. Set value: 1, Upper- and lower-limit alarm
✽3. Set value: 4, Upper- and lower-limit range
✽4. Set value: 5, Upper- and lower-limit with standby sequence

overlaps.
• Case 3: Always OFF
✽5. Set value: 5, Upper- and lower-limit with standby sequence
