1 Note Mechanical Installation
1 Mechanical Installation1.1 Note
1.2 Mechanical stroke limiting
The mechanical limiting elements built-in by the customer must be able to absorb thereactive forces and kinetic energy that is created when the end position stops arereached in order to prevent the maximum permitted feed thrust of the CMS from beingexceeded. This requires soft, damping elements. Their purpose is to absorb the energyand then limit the end position mechanically. As a rule, you should use cushioning orshock absorbers that are dimensioned accordingly.
STOPThis 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.
STOPThe customer must limit the stroke of the CMS through appropriate measures in theextended and retracted position, e.g. by using limit stops, cushioning or shock absorb-ers.

1 Calculating the stroke lengthsMechanical Installation
1.3 Calculating the stroke lengths
1.3.1 Calculating the effective strokeThe effective stroke can be calculated as follows:
Heff = A - T - 2 x S
or
Heff = HCMS - 2 x S
→ Heff < HCMS
STOPThe 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 stopsrestrict the effective stroke (Heff).

2 Operation of the Star Vario / Star Control Lubricator
2.1 Star Vario2.1.1 During operation
Observe the following points when operating the Star Vario lubricator.
• Perform inspections at regular intervals during operation. Do especially check forleaks and inspect the state of the lubricator (chapter 8.6.4 of the SEW operatinginstructions).
• Refer to the table in section 2.1.3 in case of malfunctions. Do consult the SEWcustomer 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 settingsThe operating time and the size of the LC unit can only be set when a new LC unit isbeing installed. If the setting is to be changed during operation or after the startup, anew, 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.
STOPThis chapter's content is an excerpt from the current perma operating instruc-tions.
SEW-EURODRIVE does not assume liability for the correctness and complete-ness of the content.A requirement of fault-free operation and fulfillment of any rights to claim underlimited warranty is that you adhere to the information given in the Star Vario andStar Control lubricator operating instructions by perma-tec GmbH & Co KG.
1) Lubricant container
STOP• You must never change the settings of the 4-way code switch during operation or
after startup!
STOPDo always use a new, completely filled LC unit and a new battery set each time youchanged the settings.
You must never use an LC unit that is already partially empty.
