Frequently Asked Questions about 7VGS084CD02
What does the diagnostic readout 010111 mean?
The diagnostic readout 010111 has a fault number of FL23 and a fault name of OVERF and means there is a field overcurrent (L, T).
-The field regulator is unstable.
-Field forcing at FRA (4TB20, 13PL-20) - check input scaling, (see Table 1 in the instruction book titled DC-300 Adjustable Speed Drives).
-The ADR076-FLDMX or ADR049-FTOCG are incorrect.
-The field SCR is shorted -replace the Motor Field Module.
What does the diagnostic readout 011000 mean?
The diagnostic readout 011000 has a fault number FL24 and a fault name of U3 FL which means a bad ram on the U3 8155 (L, T).
-Replace the Control card.
What does diagnostic readout 011001 mean?
The diagnostic readout 011001 has a fault number FL25 and a fault name COMTR which means there is an SCR communication failure (L, T).
-There is a low AC line voltage (less than 90% rated).
- The ADR080-CMFLM is set too high- should not exceed 1.13 X AC RMS in line voltage.
-The 1CPL is disconnected.
-The 1CPL is reversed.
-The P3-HP SEL and the JP9-11 gains are set too high on the Control card.
- The 1PL is disconnected or damaged.
-The Gate plug(s) are incorrectly connected.
-The SCR(s) have failed; try the SCR self test.
What does the diagnostic readout 011010 mean?
The diagnostic readout 011010 has a fault number FL26 and a fault name ACIOC means there is a Circulating AC line fault (in regenerative controllers only) (L, T).
-There is a low or noisy AC line.
-There is an incorrect setting of the P3-HP SEL and the JP9-11 on the Control card.
-There is noise in the SCR gate leads.
- The 1PL is disconnected or damaged.
-The SCR(s) has failed; try SCR self test.
