E5CD/E5CD-B

*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

@D Digital Temperature Controllers User's Manual (Cat. No. H224) for information on the operation of the standby sequence.

*7. Refer to the E5

@D Digital Temperature Controllers User's Manual (Cat. No.H224) for information on the loop burnout alarm (LBA).

*8. Refer to the E5

@D Digital Temperature Controllers User's Manual (Cat. No. H224) 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.
