Machine cycling erratically.
1) Verify supply line voltage.
2) Check 2CR relay.
3) Verify blade sensor operation. When blade is up, both
LEDs are on, when blade is down both sensors are off.
Verify 15 mm (0.060”) clearance between sensors and
the cam. (Section 7.12)
4) The CYCLE pushbutton switch may need replacement.
(See Section 7.16.)
5) Replace blade motor brushes.
6) If Blade motor shaft has excessive play, replace motor.
The machine is excessively noisy
when the blade motor runs.
1) The blade may have excessive side-to-side play in the
die block. Sharpen and lubricate blade and die block.
(Section 7.3 through 7.10).
2) Blade motor bearings may be worn; this requires
replacing the motor.
Strip length is not consistent.
1) Check pinch roller tension. (Section 5.4.2)
2) Check the spring pressure on the idler roller. (Section
5.1.2)
3) Verify that guide rail is not binding material.
4) Clean the rollers. (Section 7.11.2)
5) Clean roller shaft bushings and inspect for damage.
6) Check and tighten roller shaft and pulley set screws.
7) Verify belt tension. Belt should deflect slightly when
pushed.
8) Replace blade motor brushes.
Strips bunching up in output,
sticking to blade, or cut twice.
1) The blade will cut accurately only when at least 19 mm
(.75”) of material is left behind the blade.
2) Clean adhesive build-up on blade and die block. (Section
7.4)
3) Static control bar may need cleaning or replacement.
(Section 7.13)
4) Sharpen blade.
5) Sharpen die block. (Note: A dull die block will dull blades
prematurely.)
Strips have rough edges
1) Clean adhesive build-up on blade and die block. (Section
7.4)
2) Sharpen blade.
3) Sharpen die block. (Note: A dull die block will dull blades
prematurely.)
4) Replace blade motor brushes.
Strips are delaminating
1) Increase the BACK UP DIST. field on the Main Control
Screen. (Section 5.3.2.)
No strips are being cut, but the HMI
displays that strips are being cut.
1) Replace blade motor brushes.
2) The blade motor or blade motor drive board may be
defective.
