2 - 10 DCS 600 Operating Instructions
2.3 Presetting the field supply unit
Make sure that existing supply voltages for power section, field supply unit (field
exciter) and field winding, fan, etc. match the rated data of the components used.
Switch ON power.
DANGER: System components now energized!
Please wait a few moments. During this time, the unit compares the phase sequence
set in the parameter with that obtaining at the power section.
If the unit outputs the "Phase sequence fault of power section” signal (F 38 PHAS
SEQU):
- switch off unit completely and disconnect from the mains, interchange two phases
at the input, and start again from the beginning of this chapter.
or
- enter: 42.01 = R-T-S and then acknowledge fault signal.
Unit will automatically adapt to phase sequence; this signal is to be interpreted as
information to the effect that the fans' direction of rotation may be wrong for size-C3
or size-C4 units (observe direction of arrow on the fan).
Only for uncontrolled field supply with SDCS-FEX-1!
15.05 = 1
Check field current and field voltage by measuring them.
Switch OFF power!

Only for controlled field supply with SDCS-FEX-2 or DCF 503/DCF 504!
15.05 = 2
41.03 = Rated motor field current has already been set
44.17 = Field current for "Under-excitation" signal
Check field current and field voltage by measuring them;
if necessary, correct field current with 41.03.
