TROUBLESHOOTING
FAULT PROBABLE CAUSE REMEDY
Machine does not
power up
Wrong or non-existent input
power source. Blown fuse or
tripped circuit breaker.
Check input power and verify
voltage
Check and replace fuses. Reset
circuit breakers
Oil leaking from
breather Normal expansion of gearbox
oil Let oil purge from gearbox and
take no further action.
Home position is not in
correct position. Loss of power during bending,
or service work was performed
Go to homing screen on controller
and repeat homing sequence. If
not accessible, contact factory.
Material slips in hook
arm
Too much oil on tubing or oil is
on the die groove. Clear
Radius is too tight. Material
has too thin of wall thickness.
Clean material and die groove with
solvent. Increase clear radius.
Increase wall thickness. Material
may need to be clamped top hook
arm to prevent slipping. Only the
counter die should be lubed
Poor bend results
Worn counter die. Worn die
groove. Wrong size material
and or wall thickness. Too tight
of a clr.
Replace counter die. Replace die.
Verify material size is correct.
Verify clr
Twisting material
Bend die is not bolted down,
Misaligned counter die, worn
spindle bearing
Verify the bend die is bolted down
to the spindle. Check counter die
alignment. Replace spindle
bearing
Machine overloads and
wont bend
Material is too big for
machines capacity. Tensile
strength of material is too high.
Input power is too low.
Bending speed is too fast. No
lube on counter die.
Verify material wall thickness and
diameter for capabilities. Get
material with lower tensile
strength. Lower bend speed. Verify
input power.
Inaccurate bending
Counter Die leadscrew
position is changing. Material
diameter is not consistent
Verify that the counter die
leadscrew is holding its position via
the counter. Verify material
diameter with a caliper size.
WARNING:
Make sure the electrical disconnect is OFF before working on
the machine. Use the lockout provided on the main disconnect switch.
Wait at least 1 min before working on any circuit, because the VFD capacitors may
have energy stored.
Always follow proper safety precautions when working on or around any machinery.
