2-2
RAP 1.1 AC Power to the Punch
Initial Actions
Make sure that the Punch Main Power Switch/
Circuit Breaker is switched on. Check fuse FS-
1 on the +24VDC Power Supply PWB (PL 3.1).
If this fuse is blown, the machine may appear to
have a problem with main AC Power.
Procedure
1. Remove the Punch Rear Covers.
WARNING
AC voltages are dangerous. Use
extreme care to check the voltages.
2. Connect the Power Cord and switch on the
main power.
3. Measure the AC input voltage at the P/J1
Line Connector, across the brown and blue
wires, on the Punch AC/DC Distribution
PWB.
The voltage is within 108 VAC to 120 VAC
tolerance.
Y N
Go to Step 5.
Go to Step 4.
4. Measure the AC input voltages at P/J2 on
the AC/DC Distribution PWB, across the
brown and blue wires.
The voltages are within 108 VAC to 120
VAC tolerance.
Y N
Replace the Punch AC/DC
Distribution PWB (PL 3.1).
Check the input voltage at CN 1on the +24
VDC Power Supply PWB.
The voltage is within 108 VAC to 120 VAC
tolerance.
Y N
Replace the harness between P/J 2
on the Punch AC/DC Distribution
PWB and CN1 on the +24 VDC
Power Supply PWB (PL 6.1B).
Go to Step 5.
5. Measure the AC input voltages at P/J 3 on
the AC/DC Distribution PWB, across the
brown and blue wires.
The voltages are within 108 VAC to 120
VAC tolerance.
Y N
Replace the Punch AC/DC
Distribution PWB (PL 3.1).
Check the input voltage at CN 1 on the +5
VDC Power Supply PWB.
The voltage is within 108 VAC to 120 VAC
tolerance.
Y N
Replace the harness between P/J 3
on the Punch AC/DC Distribution
PWB and CN1 on the +5 VDC Power
Supply PWB (PL 6.1B).
Go to Step 6.
6. Measure the AC voltage at the Punch
Power Switch/Circuit Breaker, across the
brown and blue wires.
The voltage is within 108 VAC to 120 VAC
tolerance.
Y N
Unplug the Punch from the wall outlet.
Disconnect the Line Filter from Punch
Main Power Circuit Breaker.
Reconnect the Punch to the wall
outlet. Check for 108 VAC to 120
VAC between the Line Filter and the
Main Power Circuit Breaker.
There is 108 VAC to 120 VAC
between these two points.
Y N
Verify the wall outlet voltage.
Check continuity on the Power
Cord, replace if necessary. If the
problem still exists, replace the
Punch Main Power Circuit
Breaker (PL 1.1I).
Replace the Line Filter (PL 1.1I).
Replace the harness between the Punch
Main Power Switch/Circuit Breaker and the
Punch AC/DC Distribution PWB (PL 6.1C).
