Switch Page Module Description
S700 4-5 Mains input
(Filter unit)
On/Off circuit breaker for mains input, inside the covers. The
breaker is intended for service/maintenance as an extra possibility
to turn off the mains for safety at work with the unit.
It shall be in On position when the covers are mounted. The breaker
also protects the generator, it trips at overcurrent (30A) plus has a
trip coil used for DC-bus overvoltage protection.
Potentiometer Page Module Description
Bias Mo 5-6 Tube power
supply
Adjustment of bias voltage for Molybden (Mo).
Bias W 5-6 Tube power
supply
Adjustment of bias voltage for Tungsten (W).
Anode drive freq. 5-7 Tube power
supply
Adjustment of drive freq. 3 - 5 Hz from its nominal value, for
decreasing noise that can occur due to mechanically vibrations
from the tube assembly.
