2. When the output is overloaded an error message will be generated.
SOLUTION: Remove the overload. Observe the output power capabilities. Refer to
Section 1.
3. There is no input to the power amplifiers from the oscillator. Check the oscillator
signals at the system interface connector:
J2-31 Oscillator Phase A
J2-6 Oscillator Phase B
J2-30 Oscillator Phase C
J2-7 Oscillator common/return
Program maximum output voltage. The three signals should be 5.0 ±0.10 VAC.
SOLUTION: If there is no signal at the Systems Interface connector replace the oscillator.
Refer to paragraph 6.10.
SOLUTION: If the signal at the System Interface connector is greater than 5.0 VAC, it may
be necessary to replace the respective amplifier. Refer to paragraph 6.11.
4. One of the internal fuses has failed.
SOLUTION: Replace the fuse. Remove the input power and allow capacitors to discharge
10 minutes. Refer to paragraph 6.11.
