*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).
*8. Refer to the E5
@ C Digital Temperature Controllers User's Manual
