Under Voltage Alarm Output; Power Factor Alarm Output; Reactive Power Alarm Output - Omron KE1 User Manual

Functions
 Under voltage alarm output
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With alarm X: Without alarm
• 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
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With alarm X: Without alarm
• 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).
 Reactive power alarm output
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With alarm X: Without alarm
• 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).
