4.10.7 Power Board_PCB2 Control Relays (0558038315)
The Power Board has seven relays mounted on it. One is used as part of the Inrush circuit, and will be dis-
cussed there (See section 4.10.12, Inrush circuit)
The remaining relays RL1 – RL4, control other functions of the PC1600.
RL1 is the gas solenoid control relay. This relay is closed when the unit is commanded to flow air for pre
-
flow, cutting operations and postflow. The signal used to close this relay comes from the control board.
RL2 is the fan relay. The fan relay closes when the unit begins a cutting operation. The fan will run as long
as the unit is cutting and will continue to run for seven and a half minutes after the unit has ceased cutting.
The signal used to close this relay comes from the control board.
RL3 is the main contactor relay. This relay closes the main contactor during cutting operations. The signal
used to close this relay comes from the control board.
RL4 – not used at this time
RL5 460 Off relay. This relay opens when 460 volts AC is NOT the input voltage
RL6 230 On relay. This relay closes when 230 VAC IS the input voltage.
