The second sensor is the phase detector, which measures the phase change compared
to a perfect 50
in series with the coil.
Both magnitude and phase information are fed to the motor drive electronics which
immediately drive the electric motors in the correct direction.
To Operate the VarioMatch Match Network in Automatic Tune Mode:
• With the VarioMatch match network connected to a generator, connect the
VarioMatch match network to AC power and it will tum on in automatic mode.
Note: To operate the VarioMatch match network in automatic tune mode when
connected to a CESAR generator, refer to the CESAR user manual.

Manual control is useful when the load isn't known and you must find the most
suitable match. Manual tune mode lets you determine whether matching is possible as
configured and if the match is achieved near the limits of one or both of the variable
capacitors.
In manual tune mode, the automatic tune feature is disabled and the capacitor
positions are controlled through the
network. When the interface signal MANUAL MODE is pulled high, the capacitor
positions follow the signals present on the match
