Manual 26086 EGCP-2 Engine Generator Control Package
Woodward 61
PT Phase A Scale
• Calibrates PT phase A voltage input.
• Adjust PT Phase A scale until these values match measured generator
voltage on A phase.
PT Phase B Scale
PT Phase C Scale
• Same as above, but for B and C phases of Gen.
CT Phase A , B and C Offset
• Calibrates CT Phase A , B , Or C input sensing of EGCP-2 at zero current.
• Measure actual gen. currents with clamp on ammeter, or panel ammeter.
Verify 0 Amps on the selected phase input.
• Calibrate selected phase CT reading in the calibration window.
• NOTE: The current reading does not go negative. Therefore, make sure
when zeroing the value that the offset adjustment is made so the current
reading just turns to zero. Verify this by increasing the offset value, seeing a
slight positive current reading, and then slowly adjust the offset value in
small increments until the current reading just changes from a positive value
to zero (0.0).
CT Phase A Scale
• Calibrates CT Phase A sensing of EGCP-2.
• Load generator and monitor gen. currents in phase overview menu.
• Measure actual gen. currents with clamp on ammeter, or panel ammeter.
• Calibrate phase A CT reading in phase overview.
CT Phase B Scale
CT Phase C Scale
• Same as CT setup for phase A.
• If CT polarity is reversed, that phase will read negative KW when loaded in
the Phase overview menu.
• If CTs are on the incorrect phases, then KVAR readings in phase overview
will be much higher than normal.
Bus PT Scale
• Similar to Gen PT scaling, but this scale is for single phase bus PT input to
the EGCP-2.
• Put EGCP-2 synchronizer in “check” mode in synchronizer setup menu.
• Start engine in run/load mode to a live bus (either paralleling to another
genset, or the Mains).
• Monitor Synchroscope status menu. Observe and calibrate U: volts reading
until measured matches monitored.
