4.10.8 Power Board_PCB2 Voltage Selection Circuit (0558038315)
SECTION 4
DESCRIPTION Of OPERATION
The input voltage selection is controlled by the, manually set, position of S2 however the voltage selection
circuit on the power board will tell the power board micro-controller that the input power is 230 or any other
voltage. This allows the power board to render some protection against major damage should the incor-
rect voltage be applied. Two relays, RL5 and RL6 provide the logic for the micro based on signals from the
input.
It is the combination of these two signals and the V bias signal that tells the power board micro controller to
energize RL5 (the NOT 460 VAC relay) and RL6 (the 230 VAC relay). If the input power switch is changed
during operation, this circuit will notify the microcontroller and the unit will be disabled until it is powered
down and powered back up. If the input voltage is not correct (230 VAC applied while the input switch is in
the 460 VAC position) the power board micro will not enable the s/- 15VDC bias voltages.
