OVR operated Ov (value) (Value of Indicator x 110(V) x PT Ratio →
Operated voltage of OVR.
UVR operated Uv (value) (Value of Indicator) x 110(V) x PT Ratio →
Operated Voltage of UVR.
OVGR operated V (value) (Value of Indicator) x 190(V) x GPT Ratio
→ Operated Voltage of OCGR.
SGR operated SGR
◆ If press the [reset] key after removing the cause of fault, a relay will be on operation.
4) Measuring display of protection relay part
◆ If press the [CHAR] key during the [Run..] is displayed at operating mode,
measurement
value will be displayed with the Ir. If repeat to press the [CHAR] key, it displays
measurement value of each contents in a row as followings. But the fact value of
measurement calculated by formula as table.
(Ir → Is → It → I → Ov → Uv → V → Io → Run..)
5) Display of System error
◆ Error code is blinking and displaying when internal trouble occurs. Error codes are
same as followings:
ERR 1 : Detect the analog circuit error of voltage or input circuit.
ERR 2 : Detect damage of back-up data
ERR 3 : Detect obstruction of internal telecommunication(RS-232C)
