E5EC/E5EC-B/E5AC

*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 loop burnout alarm (LBA).

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.

*10.This value is displayed only when a remote SP input is used. It

functions in both Local SP Mode and Remote SP Mode.
