Figure 5-17. Circuit board of the 50W Power Amp showing locations of jumpers, switches, connectors,
potentiometers.
As shown above; effective October 2010, two switch blocks have been added to the Power Amplifier
Circuit Board. These DIP switches are factory set to protect the circuit board from overvoltage or
excessive phase angle situations. See Table 5-16 for a description of the switch settings.
If the protective circuits are activated the Power Amplifier will shut down for approximately 2.5
seconds and then come up for 25ms. This pattern will continue until the safety parameters are met and
the condition cleared.
