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.
*6.
