• This function is available when output terminal function setting is selected as an alarm
after the setting of alarm parameter setting and alarm output setting.
• Reactive power upper limit alarm threshold : -120000000 to 120000000 var (Initial
value: 1000 var)
• Reactive power upper limit alarm hysteresis : 0 to 24000000 var (Initial value: 100 var)
• Reactive power upper limit alarm on-delay : 0.5 to 10.0 s (Initial value: 0.5 s)
• Reactive power lower limit alarm threshold : -120000000 to 120000000 var
(Initial
value: 300 var)
• Reactive power lower limit alarm hysteresis : 0 to 24000000 var (Initial value: 100 var)
• Reactive power lower limit alarm on-delay : 0.5 to 10.0 s (Initial value: 0.5 s)
*1. CTD8E (CT expansion) can perform the two-system setting only when it is connected to
PMU2A (power two-system).

• This function is available when output terminal function setting is selected as an alarm
after the setting of alarm parameter setting and alarm output setting.
• Upper-limit temperature alarm threshold
: -58.0 to 212.0 (Initial value: 80.0)
• Upper-limit temperature alarm hysteresis
: 0.0 to 10.0 (Initial value: 5.0)
• Upper-limit temperature alarm on-delay
: 0.5 to 10.0 s (Initial value: 0.5 s)
• Lower-limit temperature alarm threshold
: -58.0 to 212.0 (Initial value: 0.0)
• Lower-limit temperature alarm hysteresis
: 0.0 to 10.0 (Initial value: 5.0)
• Lower-limit temperature alarm on-delay
: 0.5 to 10.0 s (Initial value: 0.5 s)

• This function is available when output terminal function setting is selected as a reverse
phase.
• If the condition in which voltage phase order has changed continues for 0.1 s or more, the
alarm output is turned ON.
• Setting range: OFF, ON (Initial value: OFF)
* Since the state where phases are not normal is judged as reverse phase, phase-loss may
be judged as reverse phase.
