Protection 4)

The absolute linear encoders of theLIC 4100 series are an ideal position
feedback solution for linear axes in safetyrelated applications. In conjunction witha safe control, the encoders can be usedas single-encoder systems in applications
with control category SIL 2 (as perEN 61508) or performance level “d”(as per EN ISO 13849).

The reliable transmission of the position isbased on two independently generated
absolute position values and on error bits
provided to the safe control. The functionsof the encoder can be used for numerous
safety functions of the complete system asper EN 61800-5-2.
The LIC 4100 linear encoder can provide asafe, absolute position value at any time—
including immediately after switch-on.
Purely serial data transfer is performed via
the bidirectional EnDat 2.2 interface.

In addition to the data interface, themechanical connection of the encoder tothe drive is also safety-relevant. In table D8of the standard for electrical drive systems(EN 61800-5-2), the loosening of themechanical connection between theencoder and the motor is listed as a fault
that requires consideration. Since it cannot
be guaranteed that the control will detectsuch errors, fault exclusion for theloosening of the mechanical connection isrequired in many cases.
Unless otherwise specified, HEIDENHAIN
encoders are designed for a service life of
20 years (in accordance with ISO 13849).

3)

If necessary, use a suitable enclosure with seal and sealing air.

Fault exclusion for the loosening of themechanical connection
The machine manufacturer is responsible
for the dimensioning of mechanicalconnections in a drive system. During themechanical design phase, the OEM will
ideally consider the conditions within theapplication. Verifying a safe connection,
however, is both cost- and time-intensive.
That’s why HEIDENHAIN has developed a
type-examined mechanical fault exclusion
for the LIC 4100 series.

Mounting and operating conditions
This fault exclusion has been qualified for awide range of encoder applications and isensured for the operating conditions listed
below.

During temperature changes, different
coefficients of thermal expansion result
due to the different materials of the scaletape and the mounting surface. The localized
shift resulting from different coefficients ofthermal expansion between the scale tapeand the mounting surface (shearing of theadhesive film) must not exceed a value of0.75 mm. It is from this that the statedmeasuring lengths arise. Longer measuring
lengths are possible in individual cases.
This must be checked for the given
customer application.

film, with pressure applied evenly with aroller. The scale tape is additionally secured
by a screw (punched hole in scale tape).
The mounting aid (included in delivery)
facilitates the symmetrical alignment of thescrew to the punched hole.
