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).

✽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

For Upper- and Lower-Limit Alarm Described Above

• Case 1 and 2

Always OFF when the upper-limit and lower-limit hysteresis

overlaps.

• Case 3: Always OFF

✽5. Set value: 5, Upper- and lower-limit with standby sequence

Always OFF when the upper-limit and lower-limit hysteresis

overlaps.
