They are +5, +15, -15,and +24 VDC. (0V (zero volts) is connected to thecontrol’s earth ground.)- Is short circuit protected onall DC outputs.- Has a RED LED displayed in front to indicate DCvoltage faults.If the RED LED is FLASHING, there is a fault on the 24VDC, possibly a short. If the RED LED stays ON, then+5 or +15 VDC has a fault, possibly a short. If LED isOFF then there is no fault or no power.All of the DC voltages are fed to the back plane then onto all the computer boards. When all boards receivepower, they will begin self diagnostics.+5 VDC is fed to pin D32, on the back of the powersupply GS1 XP1, for the optional Winchester memory.This is a good place to check the 5 VDC.+5 VDC is also used to power theFloppy Disk Drivethrough the Back Plane AP80:X22 pin 2.24 VDC is used in many different areas of the controlcabinet.24 VDC is supplied for Customer Connections. Itgoes from GS1:XP1 pin B14 on the back of the powersupply. Then on to terminal block XS3/XT3, terminalsA15, B15, A16, B16, and C16.24 VDC goes to the optional 230 VAC manipulator fancontactor FC1 CR at KT1.24 VDC also goes through door switch SB1 to theDriveCooling Fans, EV1-EV7 if applicable.24 VDC is also fed through GS1:XP1 pin D14 to supplyan Enable Signal to the drive system AP9:XP1 pin 4.The drive system can not be started or run without thisvoltage.Sheet 6, line 17 ..............Fig. 4-2 ..............Fig. 4-1 ..............Sheet 6, line 17 ..............Fig. 4-2 ..............Sheet 6, line 19 ..............Fig. 4-2 ..............Sheet 14, line 14 ............Fig. 4-2 ..............Sheet 6, line 00 ..............Fig. 4-2,3 ...........Sheet 6, line 02 ..............Sheet 25, line 01 ............Fig. 4-2 ..............Sheet 6, line 03 ..............Sheet 12, line 10 ............Fig. 4-2 ..............Sheet 6, line 05 ..............Sheet 12, line 18 ............Fig. 4-2 ..............Artisan Technology Group - Quality Instrumentation ...
