General Safety Instructions
As the unique actuator codes are not evaluated, the CES-AZ-UES-... 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 work Ì after the replacement of a CES component Ì after an extended period without use Ì 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 regulations Ì 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-AES... complies with the following safety requirements:
Ì Category 4, PLe according to EN ISO 13849-1 Ì 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 system consists of three components:
Ì Coded actuator Ì Read head Ì Evaluation unit
The number of read heads that can be connected depends on the evaluation unit:
CES-AZ-AES-01B
CES-AZ-AES-02B
CES-AZ-AES-04B ¨ 4 read heads
It is also possible to connect a start button (monitoring of the falling edge) and a feedback loop for monitoring external relays and contactors.
The individual configuration is defined by a setup procedure.
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-UES... 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 heads are fastened to the fixed part of the safety guard and are each 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 read head by induction and data can be transferred.
The bit pattern read is compared with the code saved in the evaluation unit. If the data match, the door monitoring output O1 or O1...O2 or O1...O4 (semiconductor output) on the related read head is set HIGH. If all data for all read heads activated match, the safety outputs (relay outputs) are then enabled. The OUT LED illuminates.
¨ 1 read head
¨ 2 read heads
Optionally, a feedback loop can be connected to the evaluation unit. The evaluation unit can then only be started with the feedback loop closed. A welded contactor contact in the release path will thus be detected the next time the machine is started.
Due to the combination of dynamic polling of the actuators and the redundant, diverse design of the safety electronics with two safety outputs, the evaluation unit will enter the safe state with every detectable fault.
When a safety guard is opened, the safety outputs switch off the safety circuit and the OUT LED goes out. The state of the safety outputs is monitored internally by positively driven NC contacts (relay output).
6
Page 7
Operating Instructions Safety System CES-AZ-UES-...
Independent of the switching state of the safety circuit, the position of all safety doors can be polled via the outputs O1 or O1...O2 or O1...O4.
If an internal fault occurs in the evaluation unit, the safety circuit is switched off, the diagnostic output (DIA) is set HIGH and the DIA LED illuminates red.

Installation
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 EUCHNER
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 appropriate terminal SH1 ... 4 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 U Ì The connections for the read heads are 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.

feedback loop
To achieve category 4 according to EN ISO 13849-1, it is necessary to monitor the downstream contactors (here contacts of -K3 and -K4 in the feedback loop). This example shows only an excerpt that is relevant for connection of the CES system. The example illustrated here does not show complete system planning. The user is responsible for safe integration in the overall system.
If only one enable path is to be used for control (e. g. of downstream contactors), failures involving a short circuit between the contacts on the enable path and, for example, the power supply must be excluded.
With reference to EN ISO 13849-2 Table D.5, this exclusion can be provided if
Ì the cables are inside an electrical installation space and Ì the enclosure meets the related requirements (see EN 60204-1 or IEC 60204-1).

- TST input activated (function test active)
Parameter setting
Before the system forms a function unit, the parameters are set in the evaluation unit by the user (number of connected read heads, with or without automatic start, with or without feedback loop). During this process the read heads are activated.
These configuration parameters are saved in the non-volatile memory in the evalu­ation unit.
Important!
The safety outputs are open during the parameter assignment. The system is in a safe state.
Ì During the parameter setting the following conditions must be met:
Ì There must be no state change, e.g. opening a safety guard or closing a
further safety guard or a change in the signal on the terminals for the start button and the feedback circuit.
Ì The power supply must not be switched off.
Ì If these conditions are not met, the evaluation unit switches to the safe fault
state (diagnostics LED illuminates) and signals this operating fault with the STATE LED by 3 short flashes that are repeated every second. The param­eter setting operation must be repeated.
Ì The number of parameter setting operations is unlimited. The evaluation unit
can be re-configured as often as required.
Ì Do not change DIP switches during operation.
To trigger a parameter setting operation, the user must perform the following actions in the stipulated order:
1. Prepare for parameter setting operation
Ì Switch off power supply U

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 for approx. 10 seconds at 15 Hz). 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.
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 60204­1 : 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 24 V DC to the test input TST.
The safety outputs are switched off, enabling testing of the complete safety circuit. The diagnostic output DIA of 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 DIA to LOW, the red LED switches off and normal operation is continued.
In Manual start operating mode, the start button must be pressed again to start the system.

Important:
After the self-test, test input TST must be reconnected to 0 V or disconnected.

Internal component failure or actuator CES-A-BMB in the inadmissible range or excessively high external
interference (EMC)
Configuration fault:
Parameter setting operation must be performed again
Possible causes:
- State change during the parameter setting operation
- The DIP switch setting and the configuration did not match during the parameter-setting operation
- DIP switch setting has been changed without parameter setting operation
- The teach-in jumper (J1, J2 or J, 0V) was fitted with power supply switched on
- Closed feedback loop (Y1,Y2) present, although a feedback loop was not present during teach-in
- 24 V signal present at the start button input (S) although teach-in was performed with "Automatic start"
operating mode.
Fault in feedback loop
Possible causes:
- Malfunction of the monitored contactor
- Following removal from the operating distance, actuator is not outside the operating distance long enough.
- Feedback loop was not closed when the evaluation unit was started.
As a result the feedback loop cannot be closed in this short time. Note the release time for the monitored contactor.
