▶
turning CW increase the level for damping generator transient output voltage.
▶
turning CCW decrease damping level to cause under damping
6.6. Choice frequency switch depending on generator frequency (SW1)
This option protects generator and AVR by decreasing generator output voltage if it reduces
generator frequency. (under frequency protection)

Frequency 50Hz system (refer to below 50Hz system)
-
Frequency 60Hz system (refer to below 60Hz system)

7. FLASH EXCITING
7.1. MANUAL FIELD FLASH ESCITING
When generator does not build up to the rated value or has no output, manual field flash exciting
could be executed as the following order. Please refer to the below drawing.
1) Remove two output lines connected to the terminals J, K of generator.
2) Prepare a12Vdc battery and a push button ,and connect them as the drawing.
3) Start engine
4) When the revolution is reached rating, push the button for short time (about 1~2sec)
5) Check the output voltage.
