E5CC/E5CC-U

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.”

Set value: 1, Upper- and lower-limit alarm

Set value: 4, Upper- and lower-limit range

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.

Refer to the E5

@C Digital Temperature Controllers User's Manual (Cat. No.

H174) for information on the operation of the standby sequence.

Refer to the E5

@C Digital Temperature Controllers User's Manual (Cat.

No.H174) for information on the loop burnout alarm (LBA).

Refer to the E5

@C Digital Temperature Controllers User's Manual (Cat. No.

H174) for information on the PV change rate alarm.

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.

Remote SP input is supported only for the E5CC.
