RAP 1.3 +5VDC Power
Description
This RAP us used to troubl5 VDC
power to the backlight in the Control Panel.
Procedure
1.
Remove the Back Panel.
2.
Switch on the Main Power Switch/Circuit
Breaker.
WARNING
There are areas of high voltage on the
Power Supply. Use caution when
working in this area with the digital
multimeter probes.
3.
Using a digital multimeter, place the
common lead on CN2, Pin 3 or 4 (black
wire) and the positive lead on Pin 1 or 2
(red wire) on the +5VDC Power Supply
PWB.
The voltage is +4.75 VDC to +5.25 VDC.
Y
N
Go to Step 4.
Go to Step 5.
4.
On the +5 VDC Power Supply PWB, check
for AC voltage on CN1, across the brown
and blue wires.
There is 108 to 120 Volts AC across the
brown and blue wires at CN1.
Y
N
Go to RAP 1.1 AC Power to the
Punch.
Go to Step 5.
5.
Switch off the Main Power Switch/Circuit
Breaker.
6.
Disconnect the Power Supply Connector
CN2 from the +5 VDC Power Supply PWB.
7.
Switch on the Main Power Switch/Circuit
Breaker.
8.
Using a digital multimeter, place the
common lead on CN2, Pin 3 or 4 (black
wire) and the positive lead on Pin 1 or 2
(red wire) on the +5VDC Power Supply
PWB.
The +5 VDC voltage is within tolerance.
Y
N
Replace the +5 VDC Power Supply
(PL 3.1).
Go to Step 9.
9.
Switch off the Main Power Switch/Circuit
Breaker. Reconnect the CN2 Connector
and disconnect P/J12 from the AC/DC
Distribution PWB. Then, switch on the
Main Power Switch/Circuit Breaker.
10. On the AC/DC Distribution PWB check for
+5 VDC at P/J5, across the black wires (Pin
3 or 4) and red wires (Pin 1 or 2).
The voltage is +4.75 VDC to +5.25 VDC.
Y
N
Check the wires and connections
between the +5 VDC Power Supply
PWB and the AC/DC Distribution
PWB. Repair or replace, as necessary
(PL 6.1B).
Go to Step 11.
11. On the AC/DC Distribution PWB, check for
+5 VDC across P/J12-+5V and P/J12-0V.
The voltage at this point is +4.75 VDC to
+5.25 VDC.
Y
N
Replace the Punch AC/DC
Distribution PWB (PL 3.1).
Reconnect P/J12. Go to Step 12.
12. On the Punch I/O PWB, check for +5 VDC
across P/J 28-+5V and P/J 28-0V.
The voltage at this point is +4.75 VDC to
+5.25 VDC.
Y
N
Check the wires and connections
between the AC/DC Distribution PWB
and the Punch I/O PWB. Repair or
replace, as necessary (PL 6.1B).
The +5VDC Circuit is OK.
