1.1 Note
1.2 Mechanical stroke limiting
The mechanical limiting elements built-in by the customer must be able to absorb the
reactive forces and kinetic energy that is created when the end position stops are
reached in order to prevent the maximum permitted feed thrust of the CMS from being
exceeded. This requires soft, damping elements. Their purpose is to absorb the energy
and then limit the end position mechanically. As a rule, you should use cushioning or
shock absorbers that are dimensioned accordingly.
STOP
This addendum contains modifications and additions made to the "CMS Electric Cylin-
der" operating instructions, publication no. 11562617, edition 05/07.
Please use the data specified in this addendum instead of the data in the opera-
tion instructions.
This document does not replace the detailed operating instructions.
STOP
The customer must limit the stroke of the CMS through appropriate measures in the
extended and retracted position, e.g. by using limit stops, cushioning or shock absorb-
ers.

Calculating the stroke lengths
Mechanical Installation
1.3 Calculating the stroke lengths
1.3.1 Calculating the effective stroke
The effective stroke can be calculated as follows:
Heff = A - T - 2 x S
or
Heff = HCMS - 2 x S
→ Heff < HCMS
STOP
The rated stroke length (HCMS), e.g. CMS71L stroke 200 mm, is only available in lim-
ited form for the customer application because safety distances (S) to the limit stops
restrict the effective stroke (Heff).

Operation of the Star Vario / Star Control Lubricator
2 Operation of the Star Vario / Star Control Lubricator
2.1 Star Vario
2.1.1 During operation
Observe the following points when operating the Star Vario lubricator.
• Perform inspections at regular intervals during operation. Do especially check for
leaks and inspect the state of the lubricator (chapter 8.6.4 of the SEW operating
instructions).
• Refer to the table in section 2.1.3 in case of malfunctions. Do consult the SEW
customer service if the problem cannot be solved.
• Check the fill level of the transparent LC unit regularly1).
• Do observe section 2.1.2 when changing the settings after startup.
2.1.2 Changing the settings
The operating time and the size of the LC unit can only be set when a new LC unit is
being installed. If the setting is to be changed during operation or after the startup, a
new, completely filled LC unit and a new battery set must be used.
If the setting is to be changed during operation, the control and the monitoring electron-
ics are interfered. Thus perma-tec cannot guarantee for a precise lubrication.

STOP
• You must never change the settings of the 4-way code switch during operation or
after startup!
STOP
Do always use a new, completely filled LC unit and a new battery set each time you
changed the settings.
You must never use an LC unit that is already partially empty.
