F0003 Undervoltage | STOP II |
Quit
Refer to F0001
Cause
-line voltage failed
-shock stressing outside the permissible limits.
Diagnosis & Remedy
Please check the following:
-is the line supply voltage within the permissible range?
-is the line supply voltage stable with respect to sporadic failures and voltage dips
F0004 Inverter overtemperature | STOP II |
Quit
Refer to F0001
Cause
-inadequate cooling
-ambient temperature is too high. ambient temperature is too high.
Diagnosis & Remedy
Please check the following:
-is the pulse frequency P1800 set to the factory setting ? If required reset P1800.
-does the ambient temperature lie within the permissible limits ?
-reduce the load and / or ensure adequate cooling
Please check the following:
-does the fan rotate if the inverter is operational ?
F0005 Inverter I2T | STOP II |
Quit
Refer to F0001
Cause
-inverter overloaded.
