Mechanical Linear Drive Unit WIESEL FORCELine
5. Commissioning
The mechanical linear drive unit WIESEL FORCELine
carry out fast linear movements with great force.
Structures in the power bridge can lead to injuries, e.g.
crushing of body parts, or to damage through collision
with other parts of the system.
Exercise the utmost caution during first
start-up.
The acceleration and retardation of the linear drive unit
can cause transported load to come loose and be
thrown off.
The manufacturer's information for any sup-
porting equipment used must be checked
against the weight and acceleration data!
The linear drive units must not be put into service until
the machinery into which it is to be incorporated fulfils
all the provisions of the EC directive relating to machin-
ery, the harmonised standards, European standards or
the applicable national standards.
To comply with the regulations concerning
electromagnetic compatibility of machines,
care must be taken in installing them.
Therefore the standards EN 50 081-2 and EN
50 082-2 should be observed to avoid
electromagnetic interference.
The electrical installation must be carried out by an EMC
expert.
Pay attention to the notes in Chapter 4 "Mounting" on
correct, safe preparation of your linear drive unit for
first operation.
Before the first power-on, make sure that the inductive
and/or mechanical limit switches are functioning pro-
perly. First cause the assembled linear drive unit to
move through its complete range of travel so slowly
that you can stop the movement in time to prevent a
possible collision.
Only after it has been verified, that when
exceeding the maximum stroke there is no
danger of collision may the unit be taken
into operation
6. Handling and operation
The mechanical linear drive unit WIESEL FORCELine
carry out fast linear movements with great force.
Structures in the power bridge can lead to injuries, e.g.
crushing of body parts, or to damage through collision
with other parts of the system.
When a linear drive unit is operated with only short tra-
vel (<100mm) always at the same place, sufficient lubri-
cation is not ensured. In this case, carry out a movement
®
over the entire range of movement at regular intervals,
after about 250 to 500 double travels.
®
can
During operation, occasionally check the correct func-
tion of the linear drive unit by visual inspection.
The operating and supervisory staff are duty bound to
inspect the linear drive units or system for outwardly
visible damage or faults at least once a shift. Any chan-
ges (including changes in the operating behaviour) that
could affect safety must be reported at once.
7. Faulty operation
In the case of faulty operation, the operating sequence
must be inspected by experts, and if necessary commis-
sioning must be repeated. Pay special attention to the
notes in Chapter 5 "Commissioning" to avoid injury and
damage.
8. Maintenance
Lubrication (MLSM 60/80 KGT, MLSM 80 ZRT)
When a linear drive unit is operated with only short tra-
vel (<100mm) always at the same place, sufficient lubri-
cation is not ensured. In this case, carry out a movement
over the entire range of movement at regular intervals,
after about 250 to 500 double travels.
During operation, occasionally check the correct func-
tion of the linear drive unit by visual inspection.
The following factors are important for exact determi-
nation of the lubrication interval:
•
Load
•
Speed
•
Movement
•
Temperature
•
Environmental conditions
Short lubrication intervals are necessary in cases
of:
•
Effects of dust and moisture
•
Heavy loading
•
High speed (up to Vmax.)
•
Short travel
•
Low age stability of the lubricant
The mechanical components must be lubricated with a
grease gun at the grease nipple on the power bridge as
specified in the table below. The covering strip should
be greased at the same time to prevent premature
®
can
wear.
