NOTE
The motor feedback system enables a radial output (Fig. 5) of the electrical
connecting cables (9), (11).
Open the cover (1) using a screwdriver, if necessary (Diagram A).
While de-energized, insert the male connector (8) into the female connector
(10). If necessary, while de-energized, insert the male connector (11) into the
female connector (12).

Lead the DSL cable (9) and, if applicable, temperature sensor cable (11) out tak‐
ing into account the cutouts in the housing (2) and cover (1).
Close the cover (1).
6 Commissioning
Commissioning the safe motor feedback systems requires that the manufacturer
of the connected drive system has complied with the safety requirements for the
drive system design, as described in the “HIPERFACE DSL ® Safety” implementa‐
tion manual.
6.1 Checking
Ensure that an EES37-2 / EEM37-2 safe motor feedback system and not an
EES37-0 / EEM37-0 standard motor feedback system is being used during com‐
missioning. This must be verified by reading out the type name (resource 083h).
In addition, the POST bit (Power-On-Self-Test) must be set for a EES37-2 /
EEM37-2 safe motor feedback system after an encoder RESET (hardware or soft‐
ware RESET). The POST bit can be acknowledged after a positive thorough check
(see "HIPERFACE DSL
®
Safety" implementation manual).
If the position offset of the motor feedback system is changed using the 101h
(“Set position”) resource or the 108h (“Factory settings”) resource, it is then nec‐
essary to verify that the sensor is providing the required position value.
Further inspection measures are not required during operation.
WARNING
The safe motor feedback system has a maximum mission time ( chapter 9 ).
After this time, it must be taken out of service.
The motor feedback system’s construction year can be found in the serial
number (SN) on the device label or on the packaging label (YYWW).
YY = represents the year (without century)
WW = represents the calendar week of the last manufacturing process.
7 Servicing
The safe motor feedback system is maintenance-free. No repair option is provided
in the event of a defect. If any device should become defective, please contact us
so we can perform an analysis to determine the cause of failure.
8 Decommissioning
8.1 Protecting the environment
The motor feedback system has been designed to minimize its impact on the envi‐
ronment. It consumes only a minimum of energy and natural resources.
b
Always act in an environmentally responsible manner at work. For this rea‐
son, please note the following information regarding disposal.
8.2 Disposal
Always dispose of unusable or irreparable devices in accordance with the applica‐
ble waste disposal regulations specific to your country.
NOTE
We will be glad to help you dispose of these devices. Please contact us.
