SOLA 4000 - Installation and Initial Start-Up

2 Initial Start-Up

•If your unit has separate supplies for the rectifier and bypass (terminals 4-L1, 4-L2, 4-L3, 4-N), switch on the external supply for the bypass. Check that the bypass supply voltage at termi- nals 4-L1, 4-L2, 4-L3, 4-N is within ±10% of the nominal input voltage.

If there are no separate input terminals then the bypass input is the same as that checked previously for the rectifier input.

•Close IUG.

•Close IRE.

?Does the display on the CPHC16 -Spcb for the bypass give the indication "P"?

yes • Open IRE and exchange any two of the cables at the bypass input terminals 4-L1, 4-L2, 4-L3.

• Return to E.

no • Are the status LEDs (green) 1, 2, 3, 14, 16, 17, 19, 26, on the operating panel continuously on?

no: Check that the mains frequency is in tolerance.

OK?

yes: Is the pcb CPHC16 -S for the bypass correctly functioning? The display should be rotating clockwise.

no: Call for service assistance.

yes: Check again the input supply. Check that it is in accordance with the UPS rating label.

no: The mains frequency must be within tolerance in order for the bypass to be availabe

yes: Continue with F.

F:Synchronisation Check • Check that the green LED LD1 on the ICT-2 pcb is permanently lit and there is no "S" indication on the bypass electronics.

•On the SS/FY pcb, measure the voltage between the screws Bypass R and Inverter R. Then repeat for the other two phases.

?Are the voltages < 25Vac?

no • If the voltage is continuously fluctuating from 0 to 400V there is a synchronisation problem. Switch off IRE and call for service assistance.

If the voltage is slightly higher but relatively constant and the default values have been re-entered using the serial interface on the CPHC16 -S p.c.b., then the synchronisation may need to be re-adjusted. This can be easily confirmed by comparing the two sinewaves for a possible phase difference.

Are the two waveforms phase-shifted?

yes: The synchronisation must be re-adjusted using the serial interface of the CPHC16 -S pcb and the PSRS232 and a portable computer.
