Backplane Voltage Output Display

The MDC22 has a backplane voltage display to ensure

the power control is working properly. The reading

should be between 4.8 and 5.3 at all times. If the

reading is not at acceptable levels the MDC22 will

not work properly. Please ensure that you have the

proper input power levels in the appropriate AC/DC

inputs.
