1.21.3.4. The generator set performance can be monitored by observing the %LOAD meter (M1), VOLTS AC meter
(M2), and HERTZ frequency meter (M4). The %LOAD meter (M1) measures the current being drawn by the load at
the load terminals (L and N) and displays the value as a percent (0 to 125) of generator set capacity. The VOLTS AC
meter (M2) measures the voltage across the power windings of the AC alternator (G2) and displays the value in VAC
from 0 to 150. The HERTZ frequency meter (M4) measures frequency across the power windings in Hz from 55 to 65.
Line fuse (F1) protects the VOLTS AC and HERTZ frequency meters from a potential over current condition.
