Correct Use
The Coded Electronic Safety switches series CES are safety devices for monitoring movable safety guards.
In combination with a separating safety guard and the machine control, this safety
component prevents dangerous machine movements from occurring while the
safety guard is open. A stop command is triggered if the safety guard is opened
during the dangerous machine function.
Before safety switches are used, a risk assessment must be performed on the
machine in accordance with:
EN ISO 13489-1, Safety of machinery. Safety related parts of control systems.
General principles for design
EN ISO 14121-1, Safety of machinery. Risk assessment. Principles
IEC 62061, Safety of machinery – Functional safety of safety-related electrical,
electronic and programmable electronic control systems.
Correct use includes compliance with the relevant requirements for installation
and operation, in particular

The safety switches CES-A-W5... are only allowed to be operated in conjunction
with the designated actuators and the related connection cable from EUCHNER.
On the use of a different actuator or another connection cable, EUCHNER provides
no warranty for safe function.
The devices are intended for use in safety circuits and, together with
connected evaluation units, permit safety functions according to
DIN EN ISO 13849-1: 2008-12 - Table 8, such as a safety-related stop function, prevention of unexpected start-up, etc.
The safety-related function of the PDF is switch-off (low) of one of the
outputs (LA, LB) when the actuator is absent.
The user is responsible for safe integration 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.
The permissible operating parameters must be observed for correct use
(see Technical data).

General Safety Instructions
Check the safe function of the safety guard particularly
after any setup work
after the replacement of a CES component
after an extended period without use
after every fault
Independent of these checks, the safe function of the safety guard should be
checked at suitable intervals as part of the maintenance schedule.
Warning!
Danger of fatal injury in the event of incorrect connection or incorrect use.
Safety switches must not be bypassed (bridging of contacts), turned away,
removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the possibility of bypassing from EN 1088:1995+A2:2008, section 5.7.
The device is only allowed to be installed and placed in operation by authorized
personnel
who are familiar with the correct handling of safety components

System Description
As the unique actuator codes are not evaluated, the CES-A-W5... version can only
be used for applications in which a hazard cannot result from possible tampering
with the system.
The safety switch CES-A-W... meets the following safety requirements:
Category 4, PLe according to EN ISO 13849-1
Proximity device with self-monitoring type PDF-M according to EN 60947-5-3.
Redundant design of the circuit in the evaluation unit with self-monitoring. As a
result, the safety system is still effective even if a component fails.
The switching state of the semiconductor outputs is checked internally when
the safety guard is opened and closed.
The CES non-contact safety system consists of three components:
Coded actuator
Safety switch with integrated read head
Evaluation unit
On the safety switch CES-A-W... the read head is integrated with the evaluation unit
in a standard housing according to EN 60947-5-2.
Each delivered actuator possesses a unique electronic coding and so is a unique
element in the system used. The code in an actuator cannot be reprogrammed.
Unlike systems with unique code detection, on the CES-A-W5... a specific code
is not requested but instead it is only checked whether the actuator is of a type
that can be detected by the system (multicode detection). There is no exact comparison of the actuator code with the code defined in the evaluation unit (unique
code detection).
The evalation unit with integrated read head is fastened to the fixed part of the
safety guard.
The actuator fastened to the movable part of the safety guard is moved towards the
read head by closing the door. When the switch-on distance is reached, power is
supplied to the actuator by the inductive read head and data can be transferred.
If a permissible code is detected, the safety outputs (semiconductor outputs)
are enabled, and the door monitoring output (semiconductor output) is also set
HIGH.
Due to the combination of dynamic polling of the actuator and the redundant,
diverse design of the safety electronics with the two feedback safety outputs, the
evaluation unit will enter the safe state with every detectable fault.
When the safety guard is opened, the safety outputs switch off the safety circuit
and the door monitoring output (OUT) is switched LOW. The state of the safety
outputs is monitored internally by two microprocessors.
On an internal fault in the evaluation unit, the safety circuit is switched off and the
OUT/ERROR LED illuminates red.
The evaluation unit has a redundant switching design with self-monitoring. This
means that the safety system is still effective even if a component fails.

Caution!
Safety switches must not be bypassed (bridging of contacts), turned away,
removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the pos-
sibility of bypassing according to EN 1088:1995.A2:2008, sec. 5.7.
Caution!
Risk of damage to equipment as a result of incorrect installation. Safety switches
must not be used as a mechanical end stop.
Fit an additional end stop for the movable part of the safety guard.
Important!
From the assured switch-off distance Sar, the safety outputs are safely shut
down.
When mounting several safety switches, observe the stipulated minimum dis-
tance to avoid mutual interference.
If the actuator is installed flush, the switching distance changes as a function
of the installation depth and the safety guard material.
Note the following points:
Actuator and safety switch must be easily accessible for inspection and re-
placement.
The switching operation must only be triggered by the specific actuator desig-
nated for this purpose.

Actuator and safety switch must be fitted so that
the front faces are at the minimum switch-on distance 0.8 x Sao or closer
(see section Operating distances). To avoid entering the area of possible side
lobes, a minimum distance is to be maintained in case of a side approach
direction. See section Typical operating distance for the related actuator.
when the safety guard is open up to the distance Sar (assured switch-off dis-
tance), a hazard is excluded.
the actuator is positively mounted on the safety guard, e.g. by using the
safety screws included.
they cannot be removed or tampered with using simple means.
Pay attention to the maximum tightening torque for the read head or safety
switch and actuator mountings of 1 Nm. For read heads/actuators made of
PE-HD, the maximum tightening torque is only 0.5 Nm.

Electrical Connection
Warning!
Loss of the safety function due to incorrect connection.
Not suitable for safety relays that realize short-circuit monitoring with different
potentials (0 V/24 V). The voltage at +LA/+LB must correspond to the informa
tion in the technical data.
-
Warning!
Caution!
In case of an error, loss of the safety function through incorrect connection.
To ensure safety, both safety outputs (LA and LB) must always be evaluated.
The monitoring output OUT must not be used as a safety output.
Lay the connection cables with protection to prevent the risk of short cir-
cuits.
Risk of damage to equipment or malfunctions as a result of incorrect connection.
The inputs on an evaluation unit connected must be positive-switching, as the
two outputs on the safety switch deliver a level of +24 V in the switched-on
state.
All the electrical connections must either be isolated from the mains supply
by a safety transformer according IEC 61558-2-6 with limited output voltage
in the event of a fault, or by other equivalent isolation measures.
For use and operation as per the requirements, a power supply with the
feature "for use in class 2 circuits" must be used. The same requirement applies to the safety outputs.
Alternative solutions must comply with the following requirements:
a) Electrically isolated power supply unit with a max. open-circuit voltage of 30
V/DC and a limited current of max. 8 A.
b) Electrically isolated power supply unit in combination with fuse as per UL248.
This fuse should be designed for max. 3.3 A and should be integrated into
the 30 V/DC voltage section.
All electrical outputs must have an adequate protective circuit for inductive
loads. The outputs must be protected with a free-wheeling diode for this purpose.

Caution!
Power devices which are a powerful source of interference must be installed
in a separate location away from the input and output circuits for signal processing. The cable routing for safety circuits should be as far away as possible from the cables of the power circuits.
If a common power supply is used, all the inductive and capacitive loads
(e.g. relay contactors) connected to the power supply must be connected to
appropriate interference suppressors.
Warning!
Electrical connection may only be performed by authorized personnel trained
in EMC and with the device and wiring isolated.
The device is fully encapsulated, it is therefore not possible to remove the lid
from the housing.
Important!
If the device does not appear to function when operating voltage is applied (e.g.
green STATE LED does not illuminate or flash), the safety switch must be returned
unopened to the manufacturer.
Safety in case of faults
The operating voltage UB is reverse polarity protected.
The contacts LA/LB and -LA/-LB are short circuit-proof, however they are not
reverse polarity protected.
A short circuit between LA and LB can only be detected by external pulsing.
A short circuit in the cable can be excluded by laying the cable with protection.
The device meets the necessary EMC regulations even with an unscreened
connection cable. For applications that are particularly sensitive to interference, a screened cable can be connected to the screen bonding clamp. This
bonding clamp can be electrically connected to the machine ground via the
fastening screws. The screen at the open end of the cable must also be connected electrically to the machine ground.
