Dipswitch S4 is a two-pole dipswitch that sets the LVDT oscillator frequency. This dipswitch is ignored if the module is con
figured as an IMHSS03 module using function code 55. Set all
poles to one (open).
If the module is configured as an IMHSS02 module using func
tion code 150, set the LVDT oscillator frequency to the fre
quency specified by the manufacturer. To set the LVDT
oscillator frequency:
1. Refer to the LVDT specifications for the recommended
LVDT primary excitation voltage frequency.
2. Refer to Table 3-4 for dipswitch settings and set S4 so that
the LVDT oscillator meets the manufacturer’s specifications.
Dipswitch S5 - Dither and LVDT Oscillator
Dipswitch S5 is an eight-pole dipswitch that sets the dither
oscillator frequency and amplitude, and the LVDT oscillator
amplitude (LVDT primary excitation voltage).
Set the dither oscillator amplitude and frequency to the value
the manufacturer of the servo valve recommends. Dipswitch
poles one and two set the dither oscillator frequency. Poles
three and four set the dither oscillator amplitude or disables
the dither oscillator circuitry. Poles five through eight set the
LVDT oscillator amplitude. Set the LVDT oscillator amplitude
to the value that the LVDT manufacturer recommends. To set
dipswitch S5:
1. Refer to the servo valve specifications for the recommended
dither oscillator current amplitude and frequency.
2. Refer to Table 3-5 for dipswitch settings and set poles 1
through 4 accordingly.
