*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 Digital Temperature Controllers User's Manual (Cat. No.
H174) for information on the operation of the standby sequence.
*7. Refer to the E5@C Digital Temperature Controllers User's Manual (Cat. No.
H174) for information on the PV change rate alarm. This setting cannot be
used with a position-proportional model.
*8. Refer to the E5@C Digital Temperature Controllers User's Manual (Cat. No.
H174) 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.
