PROBLEM
POSSIBLE CAUSE
ACTION
Bending shoe does not
move when switch is in
bend or return position.
Circuit break / power
switch in the off position.
Check that power switch (Part Number – CB25) is in the “ON” position. When
the bender is ON, the two LEDs on the Rear Handle End Plate (Part Number –
HC12) will flash red, then green to indicate normal function. The green power
light on the control pendant (Part Number – PO5C) should be lit.
No power to bender.
Check for voltage at power source. Use 110 VAC, 15 amp outlet.
Blown Fuse.*
*THIS PROBLEM WILL NOT OCCUR ON MODELS B2000-5 THROUGH
B2000-7 (SERIAL NUMBERS BEGINNING WITH LETTERS “F” - “K” OR
BENDERS MANUFACTURED BETWEEN 2001 AND 2007). THESE MODELS
DO NOT HAVE A FUSE.
Inspect 15 amp fuse and perform continuity check for a short.
If no continuity, replace fuse with new 15 amp, 125 volt fuse.
Fuse located behind handle mounting plate in the left corner of the
control panel. Refer to “Circuit Board” in “DISASSEMBLY” section (page 7)
for instructions.
12V DC power supply
failed.
Unplug bender power cord. On P.C. board, remove cover on plug.
Connect positive meter lead on black wire and negative lead on green wire.
Plug in the power cord.
Meter should indicate 12V DC.
If not, replace P.C. board, Part Number- EC2006 or HC12
Refer to “Circuit Board” in “DISASSEMBLY” section (page 7) for instructions.
Remote pendant
wiring harness is
malfunctioning.
Remote pendant wiring in the harness may be pinched or cut in a way that
causes bending to malfunction despite the indicator LEDs on Rear Handle
End Plate and Remote Pendant illuminating.
Replace wire harness. (Refer to Repair Parts List for illustration and
additional part numbers).
Refer to “Circuit Board” in “DISASSEMBLY” section (page 7) for instructions.
Power circuit on P.C.
board is malfunctioning.
Control circuit is not activating bender.
Replace P.C. board, Part Number- EC2006 or HC12
Motor overload or/
overheated.
Allow time for motor to cool. Activate bender.
If motor will not run, perform continuity check. If there is continuity, motor
is damaged and must be replaced, Part Number – CL43259
Refer to “Electric Motor” in “DISASSEMBLY” section (page 7) for instructions.
Roller Housing and
Upper Roller do not
properly lock the
conduit into place.
Upper Roller pivot is in
incorrect position.
If the Upper Roller has been disassembled in the past, the pivot may be in the
wrong position.
While facing the B2000 push handles, remove the Upper Roller (Part Number –
CK994900) and look down the bearing shaft. There will be an off-center hole
at the bottom of the bearing. If the Upper Roller is correctly installed facing to
the right, this hole should be closer to you to ensure that the pivot is in
the right position.
Refer to “Roller Housing” in “DISASSEMBLY” section (page 7) for instructions.
Incorrect rollers used.
If the Roller Housing (Part Number – CU295900K) has been disassembled in
the past, the rollers may have been incorrectly reassembled. The middle set of
1½" nylon rollers (Part Numbers – CU299281 and CU319281) must be placed
in the correct position and are not interchangeable. The upper set of 1¼"
rollers (Part Number – CU300281) can be swapped and the lower set of
2" rollers (Part Number – CU298281) can be swapped.
Refer to “Roller Housing” in “DISASSEMBLY” section (page 7) and “Roller
Housing” in “RE-ASSEMBLY” section (page 9) for instructions on assembling
the rollers.
Rollers are damaged
Replace damaged rollers.
Refer to “Roller Housing” in “DISASSEMBLY” section (page 7) for instructions.
