14.1.10 Fault Supply vol F_SPh
Main supply fault, one phase missing
•
Check that the main voltage connects simultaneous to the control voltage
• Check the connections of the terminals 19 (U1-1), 17 (U1-2) and 15 (U1-3)
In insulated or high impedance grounded networks, the zero level floats, causing errors in detecting
the actual supply voltage. Set parameter 4-10-3 to NO
14.1.11 Fault Phaseorder F_Sor
Main supply fault, incorrect phase order (supervision is carried out only once after each power-
ON)
•
Check the connections of the terminals 19 (U1-1), 17 (U1-2) and 15 (U1-3)
• Check the phase-order
• Check the phase order of the wires through the current transformers
• Check the connections of the current transformer
In insulated or high impedance grounded networks, the zero level floats, causing errors in detecting
the actual supply voltage. Set parameter 4-10-3 to NO
14.1.12 Fault CParameter F_CP
Internal parameter read or write fault
•
Incorrect check sum in reading the memory or internal hardware fault in the unit
14.1.13 Fault MParameter F_MP
Internal parameter read or write fault
•
Incorrect check sum in reading the memory or internal hardware fault in the unit
