*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 *2
• 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 Refer to the E5
@ C-T Digital Temperature Controllers Programmable Type
User's Manual (Cat. No. H185) for information on the operation of the
standby sequence.
*7 Refer to the E5
@ C-T Digital Temperature Controllers Programmable Type
User's Manual (Cat. No. H185) for information on the loop burnout alarm
(LBA). This setting cannot be used with a position-proportional model.
*8 Refer to the E5
@ C-T Digital Temperature Controllers Programmable Type
User's Manual (Cat. No. H185) for information on the PV change rate
alarm.
*9 When heating/cooling control is performed, the MV absolute upper limit
alarm functions only for the heating operation and the MV absolute lower
limit alarm functions only for the cooling operation.
