Troubleshooting

1N1 / 3N1

Hardware failures can have a severe influence on yarn quality!

They should be corrected and reset by qualified personnel only!

ATTENTION

8 Troubleshooting

8.1 Hardware Locks / Recommended Action

LOEPFE YM 1N1 / 3N1 has a built-in diagnostic function. Technical problems are indicated by means of hardware
locks. Hardware locks can only be cancelled on the LZE-V GUI.

A hardware alarm is indicated on the sensing head: Both LEDs flash. The type of alarm can be viewed on the LZE-V
screen.

Fault

Description

Possible cause

Recommended action

Hardware SE lock 0

Unspecified diagnostic lock
after restart of SE

A lock was present before Power
Down of the SE and is restored by
the LZE-V

Correct lock situations before
Power Down of SE
Reset lock and check again

Hardware SE lock 1 (*)

The SH detects no Yarn signal
although the rotor is in RUN
state

Yarn not or not correctly in the SH
measuring slot
SH lower ceramic missing
SH defective

Check Yarn position and guiding
Replace SH

Hardware SE lock 2

Measured Yarn signal is too low

Yarn position wrong
SH lower ceramic missing
SH defective

Check Yarn position and guiding
Replace SH

Hardware SE lock 3

Measured Yarn signal is too
high

Measuring slot obstructed by dust
or lint
SH defective

Remove dust or lint
Replace SH

Hardware SE lock 4

Too many Run / Stop transitions
in the measured yarn signal

Maximum piecing attempts reached
(default 20 per shift)
Yarn position wrong
SH defective

Check piecing robot and spinbox
components
Check and correct
Replace SH

Hardware SE lock 5

No communication with
YM 3N1 SH

Cable unplugged or defective
SH defective
SE has a defective input

Connect or replace cable
Replace SH
Replace SE

Hardware SE lock 6

Minimum intensity signal.
(F channel)

SH has no F function
SH defective

Install correct SH
Replace SH

Hardware SE lock 7

Maximum intensity signal.
(F channel)

Machine is producing heather yarn
SH defective

Disable F channel of YM 3N1
Replace SH

Hardware SE lock 8

Minimum intensity signal.
(P channel)

SH has no P function
SH defective

Install correct SH
Replace SH

Hardware SE lock 9

Maximum intensity signal.
(P channel)

Machine is producing synthetic yarn
SH defective

Disable P channel of YM 3N1
Replace SH

Notes:

(*) = Function not present on stand-alone installations
