Switch S3 - Dither Oscillator Frequency
Switch S3 is a two position switch that determines the dither
oscillator frequency. Set the dither oscillator frequency to the
value the manufacturer of the servo valve recommends. To set
the dither oscillator frequency:
1. Refer to the servo valve specifications for the recommended
dither oscillator frequency.
2. Refer to Table
for switch settings and set S3
accordingly.
