Correct Use
The Coded Electronic Safety systems series CES are
safety devices for monitoring movable safety guards.
In combination with a separating safety guard, this
safety component prevents dangerous machine
movements from being performed for as long as the
safety guard is open. A stop command is triggered
if the safety guard is opened during the dangerous
machine function.
Before safety components are used, a risk assess-
ment must be performed on the machine, e.g., in
accordance with:
f
EN ISO 13489-1, Safety of machinery. Safety re-
lated parts of control systems. General principles
for design
f
EN ISO 12100, Safety of machinery - General
principles for design - Risk assessment and risk
reduction
f
IEC 62061, Safety of machinery – Functional safety
of safety-related electrical, electronic and program-
mable electronic control systems.
Correct use includes compliance with the relevant re-
quirements for installation and operation, for example
f
EN ISO 13489-1, Safety of machinery. Safety re-
lated parts of control systems. General principles
for design
f
EN 1088, Safety of machinery. Interlocking devices
associated with guards. Principles for design and
selection
f
EN 60204-1, Safety of machinery. Electrical equip-
ment of machines. General requirements
f
EN 60947-5-3, Specification for low-voltage switch-
gear and controlgear. Control circuit devices and
switching elements. Requirements for proximity
devices with defined behaviour under fault condi-
tions (PDF)
The evaluation unit must be used only in conjunction
with the designated read heads and actuators from
EUCHNER. On the use of different read heads and
actuators, EUCHNER provides no warranty for safe
function.
A combination of other CES devices or devices from
other manufacturers is not allowed.
Important: The user is responsible for the integra-
tion of the device in a safe overall system. For this
purpose, the overall system must be validated, e.g.
in accordance with EN ISO 13849-2.
If a product data sheet is included with the product,
the information on the data sheet applies in case of
discrepancies with the operating instructions.
No servicing is required. Repairs to the device are only
allowed to be made by the manufacturer.

from EUCHNER may be replaced.
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
f
Check the switching function
f
Check the secure fastening of the devices and the
connections
f
Check for soiling
Check the safe function of the safety guard par-
ticularly
f
after any setup work
f
after the replacement of a CES component
f
after an extended period without use
