5.2 Temperature sensor connection
(only variants EKS36-2K, EKM36-2K)
Plug the temperature sensor (13) into the connector socket (14) volt-free.
WARNING
Since there is no electrical isolation of the temperature sensor in the motor
feedback system, only temperature sensors with double or reinforced isola‐
tion may be used.

5.3 Signals of the encoder system
The EKS36-2 / EKM36-2 safe motor feedback system provides the following sig‐
nals via HIPERFACE DSL
®
interface:
+U
/ DSL+; Supply voltage to the encoder with modulated positive data
S
signal. The operating voltage range of the encoder is between +7 V and +12
V.
GND / DSL–; Encoder ground connection with modulated negative data sig‐
nal. The operating voltage range of the encoder is between +7 V and +12 V.
Housing: to connect cable shield to housing potential
T+; Sensor signal for passive temperature sensor / temperature resistance.
T- / GND: Ground reference for passive temperature sensor / temperature
resistance sensor signal.

Commissioning
To commission the safe motor feedback system, EKS36-2 /EKM36-2, it is
assumed that the manufacturer of the connected drive system has complied
with the safety requirements for the drive system design, as described in the
implementation manual, "HIPERFACE DSL
6.1 Inspection instructions
When commissioning, ensure that a safe EKS36-2 /EKM36-2 motor feed‐
back system is used and not an EKS36-0 / EKM36-0 standard motor feed‐
back system. This must be verified by reading out the type name (resource
083h). In addition this must be verified by sending off at least one test
message (see "HIPERFACE DSL
When changing the position offset of the motor feedback system via the
resource 101h ("Set position") or 108h ("Factory settings"), you must subse‐
quently verify that the sensor is delivering the desired positional value.
Further inspection measures are not required during operation.
WARNING
Observe the service life!
The EKS36-2 / EKM36-2 safe motor feedback systems have a specified maxi‐
mum service life, after which they must always be taken out of service.
The bearing service life must be taken into account in addition to the mission
time. The parameter which is first reached depending on the application
determines the time when the system must be taken out of operation.
The year of manufacture of the motor feedback system is specified on the device
label and / or packaging label using a four digit code (yyww). The first two digits yy
specify the year (without the century), the last two digits ww specify the calendar
week of the last manufacturing process.
The EKS36-2 / EKM36-2 safe motor feedback systems issue a warning message
when their service life has expired.
