Over Current Alarm Output; Under Current Alarm Output; Over Voltage Alarm Output - Omron KE1 User Manual

 Over current 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
exceeds the over current alarm threshold). In addition, release of an alarm implements the
AND operation (when the values of all phases are lower than over current alarm threshold
and current alarm hysteresis).
• Over current alarm threshold
• Over current alarm hysteresis
• Over current alarm on-delay
* CTD8E (CT expansion) can perform the two-system measurement only when it is
connected to PMU2A (power two-system).
 Under current alarm output
