Leakage Alarm Output; Open Phase (Fixed Unbalance Factor) Alarm Output; Opposite Phase Alarm Output - Omron KE1 User Manual

Functions
 Leakage alarm output
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With alarm X: Without alarm
Selecting Leakage in the output terminal setting allows the output of leakage alarms from the
output terminal.
[Setting range]
Leakage comparison value: 30 to 1000 mA
Leakage operating time
* For details on the leakage detection function, refer to Chapter 3.4.
 Open phase (fixed unbalance factor) alarm output
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With alarm X: Without alarm
Turning on the open-phase detection function allows detecting an open phase and issuing an
alarm. Selecting Open Phase in the output terminal function setting allows the output of
open-phase alarms from the output terminal.
[Setting range]
• Open-phase alarm output is turned on when (max. difference between each phase voltage
and average voltage)/average voltage is 85% or less under the condition of open-phase
for 3-phase 3 -wire or 3-phase 4-wire system.
* For details on the open-phase detection function, refer to Chapter 3.5.
 Opposite phase alarm output
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○
O: With alarm X: Without alarm
Turning on the opposite phase detection function allows monitoring the phase sequence of
voltage and issuing an alarm when an abnormal condition is detected. Selecting Opposite
Phase in the output terminal function setting allows the output of opposite-phase alarms from
the output terminal.
[Setting range]
* For details on the opposite phase detection function, refer to Chapter 3.5.
* Since phases other than the ones detected as normal phase are classified as opposite
phase, opposite phase detection may be provided at the time of an open phase
occurrence.
