5.5 Warning for voltage miss-wiring
This feature shows alarms when voltage phase for the phase and wire type is open, when the wrong phase sequence
(for 1-phase 3-wire, 3-phase 3-wire, and 3-phase 4-wire) is detected, when the active power is a negative value, or
when the frequency goes out of the rated range (
• If the V1 voltage phase is under 85V, this is "V
R
open phase warning".
• If the V2 voltage phase is under 85V, this is "V
S
open phase warning"
• If the V3 voltage phase is under 85V, this is ""V
T
open phase warning"
• A phase sequence error occurs when the phase sequence for 3-phase 4-wire, 1-phase 3-wire, and 3-phase 3-wire
is incorrect.
• If the phase of the voltage and current differ and the active power is a negative value, the error is "Active power is a
negative value".
• If the frequency goes out of the range between 45 and 65Hz, the error is "Input frequency error warning".
Information
• If the alarm LED flashes, it cancels after you make corrections to the wiring and input and then restart the unit.
