R41 Iavg OL Adjust: sets the sensitivity of the HV transformer’s average
primary current limit circuit. This protects the power inverter from
large values of average current over a period of many inverter
cycles. This circuit does not protect against high peaks of
instantaneous current.
R149 Counter Adjust: sets the sensitivity of the arc counter circuitry which
shuts off high voltage if too many arcs or rollbacks occur in a given
period of time. It also functions as an arc rate circuit, since a rapid
succession of arcs is more apt to trip the circuit than the same
number of arcs spread out over a longer period of time.
R165 Rail Fault Adjust: sets the trip point of a circuit which is sensitive to
excessive current in the power inverter. This type of fault could
indicate that an IGBT in the inverter has failed. This circuit has a
purpose similar, but not identical, to the “Iavg OL” circuit.
However, the rail fault circuit protects against more catastrophic
events, especially faults occurring within the inverter itself. It is a
latched fault, requiring a reapplication of ‘HV ON’ to resume HV
operation. DO NOT retry ‘HV ON’ more than once or twice after a
rail fault occurs, since this indicates damage has occurred within the
inverter and further attempts to turn on HV may worsen the damage.
R137 Slow OC Adjust: sets the trip point of the slow responding overload
circuit, which monitors the output current. This circuit terminates
HV if the load demands an excessive amount of average current. It
is a latched fault, requiring a reapplication of ‘HV ON’ to resume
HV operation. (This circuit is normally set to approximately 5%
above the rated maximum load current). This circuit would function
well during an excessive increase in load which might not be
detected by the other protection circuitry.
R69 OV Adjust: sets the threshold of the overvoltage circuitry, which
monitors the output voltage. This circuit terminates HV if it detects
voltage higher than the set point. The set point is factory adjusted to
5% above the maximum rating of the supply.
R125 +10V Ref Adjust: calibrates the precision internal reference voltage
to +10.000V.
