*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

• In cases 1 and 2 above, the alarm is always OFF
if the upper-
and lower-limit hysteresis overlaps.
• In case 3, the alarm is always OFF
.
*5. Set value: 5, Upper- and lower-limit alarm with standby sequence
The alarm is always OFF
