b.
Operational Test. This test is performed with voltage regulator VR1 01 removed from the generator set.
(1)
Remove voltage regulator VR101(3, Figure 5-9) in accordance with paragraph 5-15.
(2)
Connect the voltage regulator VRl01 as shown in Figure 5-11.
(3)
Mark position of rheostat VR1Ol R11 on etched circuit board (1, Figure 5-10).
Figure 5-11. Voltage Regulator VR101, Test Setup
NOTE
R1 rheostat in test setup simulates VOLTS ADJUST rheostat R1 01 on cabinet B control panel. In
the fully counter clockwise position, generator output voltage is at minimum. When R1 is
clockwise (minimum resistance), generator is at maximum voltage.
(4)
et rheostat VR1 01 R1 1, on etched circuit board (1, Figure 5-10) fully counter clockwise.
(5)
Adjust R1 test rheostat for maximum resistance (fully counter clockwise).
(6)
lowly rotate R1 clockwise. Before reaching minimum resistance, light should come on to near full brilliance.
If light does not go on, adjust external voltage range rheostat VR101 R14.
NOTE
Normally, VR101 R14 is preset to provide RI with an adjustment span of il0 percent of rated range.
