Over voltage 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.
• Alarm judgment implements the OR operation in phases (when the value of a phase
exceeds the over voltage alarm threshold). In addition, release of an alarm implements the
AND operation (when the values of all phases are lower than over voltage alarm threshold
and voltage alarm hysteresis).
• Over voltage alarm threshold
• Over voltage alarm hysteresis
• Over voltage alarm on-delay

Under voltage 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.
• Alarm judgment implements the OR operation in phases (when the value of a phase is
lower than the under voltage alarm threshold). In addition, release of an alarm implements
the AND operation (when the values of all phases exceed under voltage alarm threshold
and voltage alarm hysteresis).
• Under voltage alarm threshold
• Under voltage alarm hysteresis
• Under voltage alarm on-delay

Power factor 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.
• Power factor alarm threshold
• Power factor alarm hysteresis
• Power factor alarm on-delay
*1. CTD8E (CT expansion) can perform the two-system setting only when it is connected to
PMU2A (power two-system).
