LAM Characteristics
The LAM system is integrated as standard in the R438 and R448 LS regulators.
Role of the "LAM" (Load Adjustment Module):
•
On load impact, the rotation speed of the generator set decreases. When it passes
below the preset frequency threshold, the "LAM" causes the voltage to drop by
approximately 13% or 25% and consequently the amount of active load applied is
reduced by approximately 25% to 50%, until the speed reaches its rated value again.
Hence the "LAM" can be used either to reduce the speed variation (frequency) and
its duration for a given applied load, or to increase the applied load possible for one
speed variation (turbo-charged engine). To avoid voltage oscillations, the trip
threshold for the "LAM" function should be set approximately 2 Hz below the lowest
frequency in steady state.
•
LAM: action eliminated by cutting strap ST5.
