Pump Electrical Troubleshooting 8.4.2
NOTE: Use Fig. 8-11 Pump Schematic while troubleshooting the pump electrical system.
Step Possible Cause If . . .
1 Is the Material Temperature at or above 275°F? • Yes go to Step 2.
• No, continue to allow the machine to heat.
2 Is there 12 Vdc between the Hose PAKSTAT
terminal #2 purple wire and terminal #8 black
ground wire?
(Refer to the pump circuit schematic Fig. 8-11
Pump Schematic )
• Yes, go to Step 3.
• No, go to Step 2a.
2a Is there 12 Vdc between the Hose PAKSTAT
terminal #1 pink wire and terminal #8 black
ground wire? • Yes, check for a broken wire or poor
wire crimp on the terminal #2 purple
wire and recheck for 12 Vdc. (If still no
voltage replace the Material PAKSTAT.)
• No, go to Step 2b.
2b Is there 12 Vdc between the Hose PAKSTAT
terminal #9 pink wire and terminal #8 black
ground wire? • Yes, check for a broken wire or poor
wire crimp on terminal #1 pink wire. (If
you have 12 Vdc on terminal #9 pink
then you must have 12 Vdc on
terminal #1 pink wire; they are the
same wire.)
• No, If this is the case you would have
had a hose heating issue.
3 Is there 12 Vdc between the terminal block
purple wire and the terminal black ground wire? • Yes, go to Step 4.
• No, check for a broken wire or poor wire
crimp between the Hose PAKSTAT
terminal #2 purple wire and the terminal
block purple wire.
4 Move to the junction box at the rear of the
machine and open the cover.
Is there 12 Vdc between the trigger red wire
coming from the control box and a nearby
ground source?
• Yes, go to Step 4a.
• No, check for a broken wire or poor wire
crimp between the junction box and the
control box red wire labeled red-trig.
4a Is there 12 Vdc between the trigger red wire
going toward the hose (just above where you
checked in Step 4) and a nearby ground
source? • Yes go to Step 4b.
• No, check for a broken wire or poor wire
crimp on the red trigger going toward
the hose.
