(5) Set value: 5 (Upper- and lower-limit with standby sequence)
• The alarm is always OFF if upper- and lower-limit hysteresis overlaps.
(6) Refer to 4-2-1 Standby Sequence for information on the operation of the
standby sequence.
(7) Refer to 4-12 of H156: Loop Burnout Alarm (LBA).
(8) Refer to PV Change Rate Alarm on page 52.
• Set the alarm type independently for each alarm in the Alarm 1 to 3 Type
parameters in the initial setting level. The default is 2 (Upper-limit alarm).
• Alarm values are indicated by "X" in the table on the previous page. When
the upper and lower limits are set independently, "H" is displayed for
upper limit values, and "L" is displayed for lower limit values.
• To set the alarm value upper and lower limits for deviation, set the upper
and lower limits in each of the Alarm 1 to 3 Upper Limit, and Alarm 1 to 3
Lower Limit parameters in the operation level.
This procedure sets alarm 1 as an upper-limit alarm. The related parameters
and settings are shown below. The alarm is output when the set point
exceeds 10°C. (In this example, the temperature unit is °C.)
Alarm 1 type = 2 (Upper-limit alarm)
Alarm value 1= 10
1. Press the O Key for at least three seconds to move from the operation

2. Select the Alarm 1 Type parameter by pressing the M Key. Confirm that
the set value is 2. The default value is 2 (Upper-limit alarm).
3. To return to the operation level, press the O Key for at least one second.
