ZENIT 71
CHECKS AND MAINTENANCE
Cleaning the Optics
In cases of substantial dirt accumulation, the cleaning of the
optic field by means of cotton swabs is recommended.
!
Under no circumstances should hard/sharp objects
be used for cleaning! Risk of damage!
!
If marking paint, Paraffin or antistatic oils are used,
the optics must be cleaned in shorter intervals.
Light soiling such as dust can be removed using our proven
TK-Clean (Part No. 014359.900) cleaning agent.
Heavy soiling (i. e. wax residue) can be removed using one of
the following agents:
ƒ
“Zippo Premium Lighter Fluid” lighter fluid
ƒ
“Ronsonol Lighter Fluid” lighter fluid
ƒ
Medical grade benzene (Do not use benzene, see Prohi-
bited Solvents!)
ƒ
n-Heptane (C
7
H
16
)
ƒ
Cypar7, Cycloaliphat (C
7
), a SHELL product
Note :
These solvents are highly inflammable, hazardous
goods and excluded from normal air and surface trans porta-
tion. For this reason, they have to be procured locally. As a re-
sult of their world-wide availability and good cleaning effect,
we recom mend the use of lighter fluids.
Forbidden Substances
!
Loepfe strictly declines any responsibility for dam-
age claims resulting from the use of un suitable
cleaning substances!
The substances listed below must be avoided by all means,
as their use will destroy the optical system:
ƒ
Aromatic hydrocarbons, e.g. benzene, benzole, toluol
ƒ
All kinds of alcohol, e.g. methanol, ethanol
ƒ
Spirit
ƒ
Acetone
ƒ
Automobile and aviation gasoline
Replacement of AWE or Sensing Head
When replacing an AWE or a sensing head, it must
be ensured that an identical AWE or an identical
sensing head is used! Do not mix different Zenit
versions within one machine! The functionality
of the equipment is not guaranteed when differ-
ent versions (A(UR), B or C) are used within a ma-
chine/group!
A false AWE or TK version causes the display of an error
message.
When replacing the AWE or a sensing head, a reset must be
performed on the AWE. Press the test button on the sens ing
head for five seconds = Reset AWE.
Additionally, a Spindle Adjust must
always
be performed on
this winding unit. (See the Diagnosis menu.)
!
The wound yarn (80 m) could still have faults since
the clearing is not active during the Adjust process.
If unjustified yarn count or cluster alarms are determined af-
ter a Spindle Adjust, the reduction has to be increased in the
Base Settings menu.
