Reactive power alarm output

PMU1A PMU2A
(Electric (Power
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.
• Reactive power upper limit alarm threshold : -120000000 to 120000000 var (Initial
• Reactive power upper limit alarm hysteresis : 0 to 24000000 var (Initial value: 100 var)
• Reactive power upper limit alarm on-delay
• Reactive power lower limit alarm threshold : -120000000 to 120000000 var
• Reactive power lower limit alarm hysteresis : 0 to 24000000 var (Initial value: 100 var)
• Reactive power lower limit alarm on-delay
*1. CTD8E (CT expansion) can perform the two-system setting only when it is connected to
PMU2A (power two-system).

Temperature alarm output

PMU1A PMU2A
(Electric (Power
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
• Upper-limit temperature alarm hysteresis
• Upper-limit temperature alarm on-delay
• Lower-limit temperature alarm threshold
• Lower-limit temperature alarm hysteresis
• Lower-limit temperature alarm on-delay

Reverse phase alarm output

PMU1A PMU2A
(Electric (Power
power) two-system)
• 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.
