This error can be ruled out as the sine/cosine signals are detected and processed
separately.
The encoder does not use any multiplexers for these signals.
Impermissible encoder supply voltage levels are detected using the measures descri‐
bed in see "Analog sine/cosine signal faults", page
length specified there is particularly useful for undervoltage monitoring.
To contain errors from common causes and enable early error detection, the supply
voltage of the encoder must be monitored to ensure that it complies with the limits
specified in the technical data.
If it is not possible to ensure that the encoder system will be operated within the
permissible temperature range, the system operator must take suitable measures to
ensure that the specified temperature range is complied with.
Errors resulting from operation at impermissible temperatures are detected using the
measures described in section
The drive unit must be connected to the hollow shaft encoder using a high force clamp
connection or a form-fit and a high force clamp connection. Using a feather key will
prevent the encoder from being twisted radially.
A feather key must be used for drive shafts with a diameter of 6 mm, 8 mm, and 3/8".
This ensures that the over-dimensioning required to rule out errors caused by the loss
of the shaft connection.
To find out the requirements for mounting the feather key on the drive shaft,
►
refer to the dimensional drawings at the end of the operating instructions on the
language-neutral supplementary sheet. The material from which the customer-sup‐
plied drive shaft is made must have a tensile strength of at least 530 N/mm².
The shaft coupling is part of the safety-related function chain and must be dimensioned
and validated accordingly by the user. It is not an integral part of the safety assessment
carried out by SICK AG.
Connect the encoder and the drive system using a flexible coupling.
►
Use a coupling that is suitable for the application. Couplings must comply with the
►
requirements specified in IEC 61800-5-2:2016 (see
Observe the technical data and mounting instructions of the coupling used.

The following mechanical designs are available for a positive connection (see dimen‐
sional drawings at the end of the operating instructions (on the language-neutral sup‐
plementary sheet)):
