Commissioning
NOTE
Do not commission without a thorough check by qualified safety personnel!
Before you commission a system or a machine into which the DFS60S Pro is
integrated for the first time, the machine or system must be checked and
approved by qualified safety personnel. Observe the notes provided in
Observe the initialization time after switching on. The encoder does not out‐
put any valid signals during this time.
Check whether all the safety functions work as planned at all the relevant
speeds.
Check whether the maximum temperature that arises at the encoder’s oper‐
ating point while the encoder is being operated (see
,
“A”) is within the operating temperature range specified in the technical data.
If the temperature at the operating point is above 70 °C:
–
Attach the pictogram “Warning! Hot surfaces” in accordance with
IEC 60 4175041 in a visible location on the encoder housing.
–
Explain the meaning of the pictogram in the operating instructions of
the machine into which the encoder is being integrated.
7.1 Inspection
Further inspection measures are not required during operation.
8
Servicing
The DFS60S Pro is maintenance-free. Repairs cannot be carried out in the
event of a defect. Please contact us if you have any complaints.
Observe the mission time. The DFS60S Pro safe encoder has a maximum
mission time after which it must always be taken out of service. The bearing
service life must be taken into account in addition to the mission time T
M
.
The parameter which is first reached depending on the application deter‐
mines the time when the system must be taken out of operation.
The encoder’s year of manufacture is specified on the device label or pack‐
aging label as a four-digit code (yyww). The first two digits (yy) represent the
year (without the century), and the last two digits (ww) represent the calen‐
dar week of the manufacturing process.

Decommissioning
9.1 Protecting the environment
The safety encoder is designed to minimize its impact on the environment. It uses
a minimum of energy and resources.
b
Always act in an environmentally responsible manner at work. For this rea‐
son, please note the following information on disposal.
9.2 Disposal
Always dispose of unusable or irreparable devices in accordance with the
applicable waste disposal regulations specific to your country.
NOTE
We will be glad to help you dispose of these devices. Please contact us.
