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:

General Safety Instructions
As the unique actuator codes are not evaluated, the CES-AZ-UBS-... version can only
be used for applications in which a hazard cannot result from possible tampering
with the system.
Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to severe injuries to personnel.
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
Ì after any setup workÌ after the replacement of a CES componentÌ after an extended period without useÌ 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!
Important!
Danger of fatal injury in the event of incorrect connection or incorrect use.
Ì 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
Ì who are familiar with the correct handling of safety components Ì who are familiar with the applicable EMC regulationsÌ who are familiar with the applicable regulations on health and safety Ì who have read and understood the operating instructions.
Prior to use, read the operating instructions and keep these in a safe place.
Ensure that the operating instructions are always available during mounting,
setup and servicing work. 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 operating instructions. You can download
the operating instructions from www.EUCHNER.de.

Function
The safety system CES-AZ-UBS... complies with the following safety requirements:
Ì Category 3, PLe according to EN ISO 13849-1Ì Proximity device with self-monitoring type PDF-M according to EN 60947-5-3.Ì 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.
Ì When the safety guard is opened and closed, it is checked whether the safety
system relays open and close correctly.
The CES non-contact safety systems consist of three components:
Ì Coded actuator Ì Read headÌ Evaluation unit
1 read head may be connected to the evaluation unit CES-AZ-UBS...
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-AZ-UBS... a specific code is
not polled 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 read head is fastened to the fixed part of the safety guard and is connected
to the evaluation unit via a two-core screened cable.
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.
The bit pattern read is compared with the code saved in the evaluation unit; if the
data matches, the safety outputs (relay outputs) are enabled and the door monitoring output OUT (semiconductor output) is also set HIGH.
Due to the dynamic polling of the actuator and the redundant, diverse design
of the safety electronics, 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 circuits
and the door monitoring output (OUT) is switched LOW. The state of the safety
outputs is monitored internally by positively driven NC contacts (relay output).
If an internal fault occurs in the evaluation unit, the safety circuits are switched
off, the diagnostic output (ERROR) is set HIGH and the ERROR LED lights up red.
The safety contacts on evaluation unit can also switch small currents. Since small
currents can be switched, the user has the option of connecting the evaluation
unit directly to a safe control system.

Caution!
Safety switches must not be bypassed (bridging of contacts), turned away,
removed or otherwise rendered ineffective.
Ì 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.
Ì The evaluation unit must be mounted in a control cabinet with a minimum
degree of protection of IP 54. A snap-in element on the rear of the device is
used for fastening to standard rails.
Ì If several evaluation units are mounted side by side in a control cabinet with-
out air circulation (e.g. fan), a minimum distance of 10 mm must be maintained between the evaluation units.
The distance enables heat from the evaluation unit to dissipate.
Caution!
Risk of damage to equipment as a result of incorrect installation. Read heads
or actuators must not be used as a mechanical end stop.
Ì Fit an additional end stop for the movable part of the safety guard.
Important!
Ì From the assured switch-off distance S
, the safety outputs are safely shut
ar
down.
Ì When mounting several read heads, observe the stipulated minimum dis-
tance to avoid mutual interference.

Note the following points:
Ì Actuator and read head must be easily accessible for inspection and replace-
ment.
Ì The switching operation must only be triggered by the specific actuator desig-
nated for this purpose.
Ì Actuator and read head must be fitted so that
Ì the front faces are at the minimum switch-on distance 0.8 x S
(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.
Ì when the safety guard is open up to the distance S
tance), a hazard is excluded.
Ì the actuator is positively mounted on the safety guard, e.g. by using the
safety screws included.
Ì they cannot be removed or tampered with using simple means.
Ì 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!
In case of an error, loss of the safety function through incorrect connection.
Ì The monitoring output OUT must not be used as a safety output.Ì Lay the connection cables with protection to prevent the risk of short cir-
cuits.
Caution!
Risk of damage to equipment or malfunctions as a result of incorrect connection.
Ì 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.
Ì 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.
Ì 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.
Ì Use cable material made of copper with a temperature resistance of at least
75 °C.
Ì The tightening torque for the screws on the connection terminals must be
0.6 ... 0.8 Nm.
Ì The connection cable for the read heads must only be extended using EU-
CHNER plug connectors and adequate consideration must be given to EMC.
Intermediate terminals must not be used.
Ì The screen on the connection cable for the read head must be connected to
the terminal SH1 on the evaluation unit. The portion of cable from which insulation is stripped should be kept as short as possible (max. 3 cm).
Safety in case of faults
Ì The operating voltage UÌ The connection for the read head is not short circuit-proof.Ì A short circuit between 13/14 and 23/24 can be detected only by means of
external pulsing.
Ì A short circuit in the cable can be excluded by laying the cable with protection.

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.
Functional Check
After installation and any fault, the safety function must be fully checked. Proceed
as follows:
Warning!
Danger of fatal injury as a result of faults in installation and functional check.
Ì Before carrying out the functional check, make sure that there are no per-
sons in the danger area.
Ì Observe the valid accident prevention regulations.
1. Switch on operating voltage.
Ì The safety switch carries out a self-test.
The green STATE LED flashes up to three times.
The STATE LED then lights up continuously.
The OUT and ERROR LEDs do not light up.
2. Close all safety guards.
Ì The machine must not start automatically.Ì The green STATE LED and the yellow OUT LED light up continuously.
3. Enable operation in the control system.
4. Open the safety guard.
Ì The machine must switch off and it must not be possible to start it as long as
the safety guard is open.
Ì The green STATE LED lights up continuously; the OUT and ERROR LEDs do not
light up.
Repeat steps 2-4 for each safety guard.

Page 15
Operating Instructions Safety System CES-AZ-UBS-01B
Self-test with test input TST
On electromechanical safety switches or magnetic switches, the function test can
be performed by cyclically opening the safety guard. From category 2 according
to EN ISO 13849-1 and in accordance with EN 60204-1 : 1997 (sec. 9.4.2.4), a
function test must be performed on the entire safety system on start-up or after
defined intervals.
Testing of the internal function of the device is not necessary because the device
monitors itself in real time. Welding of an output contact (relay output) is detected
by the device at the latest the next time the safety guard is opened. A short circuit
in the output cable is not detected by the device.
In addition, the entire safety circuit can be tested without opening the safety guard.
For this purpose, opening of the safety guard can be simulated by applying
DC 24 V to the test input TST.
The safety outputs are switched off, enabling testing of the complete safety circuit.
The diagnostic output ERR on the evaluation unit is also set HIGH as a monitoring
function.
When the test input TST is reset, the evaluation unit resets the diagnostic output
ERR to LOW, the red LED switches off and the safety outputs are switched on again.
This permits self-testing of the safety system without opening the safety guard.
