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

Along with the safety function, the safety switch CES-A-S... has an identification
function that provides position sensing. The position function has no safety function
and is not allowed to be used for safety-related polling.
The safety switch CES-A-C5... is only allowed to be operated in conjunction with the
designated EUCHNER actuators (see Combinations table). On the use of a different
actuator, 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).
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.

General Safety Instructions
The number of teach-in and switching operations is saved in the internal memory in
the evaluation unit. If necessary, this memory can be read by the manufacturer.
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.
The year of manufacture of the device can be derived from the serial number on
the rating plate.
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.
Important!
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
who are familiar with the applicable EMC regulations
who are familiar with the applicable regulations on health and safety
who have read and understood the operating instructions and the system
manual
Prior to use, read the operating instructions and the system manual of the CES
components used, and keep these in a safe place. Ensure the operating instructions and the system manual are always available during mounting, setup and
servicing. EUCHNER cannot provide any warranty in relation to the readability
of the CD for the storage period required. For this reason you should archive
a printed copy of the system manual. If you should lose the operating instructions or the system manual, you can download these documents from www.

System Description
The safety system CES-A-S... complies with 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:
1 coded safety actuator as well as up to 14 coded position actuators (dogs).
Safety switch with integrated read head
Evaluation unit
On the safety switch CES-A-S... the read head is integrated with the evaluation unit
in a standard housing according to EN 60947-5-2.
Each delivered safety actuator possesses a unique electronic coding and so is
a unique element in the system used. The code in an actuator cannot be reprogrammed. The position actuators have a fixed transponder number from 2 to F
(hex). Up to a maximum of 15 different actuators can be used per device: 1 safety
actuator (red) and 14 different position actuators (green).
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.
For safety actuators the bit pattern read is compared with the code saved in the
evaluation unit, if the data match the safety outputs are enabled (semiconductor
outputs LA and LB). For position actuators the related transponder number is output
to a higher level control system on the four semiconductor outputs (D0, D1, D2,
D3) as a 4-bit binary code. The four LEDs (D0, D1, D2, D3) on the device indicate
the status of the semiconductor outputs (D0, D1, D2, D3).
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.
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.
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.
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 screen at the open end of the cable must also be connected electrically to
the machine ground.

Important!
To ensure safety, both safety outputs (LA and LB) must be evaluated.
To achieve category 4 according to EN ISO 13849-1, it is necessary to monitor the downstream contactors.
Warning!
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.
Single-channel use of the safety outputs leads to a reduction of the category

In case of an operating fault, the evaluation unit can be reset to the operating state
by interrupting the power supply for approx. 10 seconds.
System Manual Safety System CES-A-S5H01
Teach-in function for actuator
The safety actuator must be allocated to the evaluation unit using a teach-in function before the system forms a functional unit. During a teach-in operation, the
safety outputs and the door monitoring output OUT are LOW, i.e. the system is in
the safe state.
Important!
Repeated teach-in of the same actuator on the same evaluation unit is not
possible.
The number of teach-in operations on one evaluation unit is limited to a maxi-
mum of 8
The evaluation unit can only be operated with the last actuator taught.
A teach-in operation is invalid if:
the teach-in operation is cancelled before the green flashing LED goes out
the power supply is switched off during the teach-in operation.
When the evaluation unit is switched on (operating voltage is applied), the
STATE LED signals the number of possible remaining teach-in operations
(see system status table).
After the eighth teach-in operation or if an "old" actuator is placed against the
read head, the system automatically switches to the teach-in mode. In both
cases, a teach-in operation with a duration of 60 seconds is started; however, the last actuator code remains active (see system status table) in the
memory – a new code is not taught.

1) Values at a switching current of 50 mA without taking into account the cable lengths.
2) Corresponds to the risk time according to EN 60947-5-3. This is the maximum switch-off delay for the safety outputs following removal of the actuator.
3) After the operating voltage is switched on, the safety outputs are switched off during the ready delay. The state of the data outputs is undefined during this time.
4) The dwell time of an actuator inside and outside the operating distance must be at least 0.5 s to ensure reliable detection of internal faults in the evaluation unit (self-monitoring).
5) Applying the limit value from EN ISO 13849-1:2008, section 4.5.2 (MTTF
= max. 100 years), BG certifies a PFHd of max. 2.47 x 10-8.
