5-62 Parameter Functions & Definitions
Alarm 2 Hysteresis
Conditions of Use: Alarm 2 must be assigned. The alarm 2 type must NOT
be 0, 12, or 13.
Alarm 3 Hysteresis
Conditions of Use: Alarm 3 must be assigned. The alarm 3 type must NOT
be 0, 12, or 13.
Function: These parameters set the hysteresis (allowed deviation from the
configured alarm value) for alarms 1, 2, and 3.
Note: Set
None as the unit for 0 to 50 millivolt.

• Alarm value 1 to 3 (page 5-16), Alarm value upper limit 1 to 3 (page
5-18), Alarm value lower limit 1 to 3 (page 5-18) (Operation function
group)
• Alarm 1 to 3 type (Initial Setting function group, page 5-59)
Transfer Output Type (900-TC8, 900-TC16)
Conditions of Use: An analog current output must be assigned/configured
Function: This parameter allows you to configure the analog current output
for a specific type of transfer output. Refer to Table 5.BU.
Note: If the analog current output is NOT used as a transfer output, configure
this parameter to OFF (default).
