2. Correct use
Safety switches series CES-I-AR are interlocking devices without guard locking (type4). The device meets the requirements according to ENIEC60947-5-3. Devices with unicode evaluation possess a high coding level, devices with multicode eval­uation possess a low coding level.
In combination with a movable safety guard and the machine control, this safety component prevents dangerous machine functions from occurring while the safety guard is open. A stop command is triggered if the safety guard is opened during the dangerous machine function.
This means:
Ì Starting commands that cause a dangerous machine function must become active only when the safety guard is closed. Ì Opening the safety guard triggers a stop command. Ì Closing a safety guard must not cause automatic starting of a dangerous machine function. A separate start command
must be issued. For exceptions, refer to ENISO12100 or relevant C-standards.
Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following standards:
Ì ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design Ì ENISO12100, Safety of machinery – General principles for design – Risk assessment and risk reduction Ì IEC62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable electronic
control systems.
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following standards:
Ì ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design Ì ENISO14119 (supersedes EN1088), Safety of machinery – Interlocking devices associated with guards – Principles
for design and selection
Ì EN60204-1, Safety of machinery – Electrical equipment of machines.
The safety switch is only allowed to be operated in conjunction with the intended EUCHNER CES actuators and the related connection components from EUCHNER. On the use of different actuators or other connection components, EUCHNER provides no warranty for safe function.
Connection of several devices in an AR switch chain is permitted only using devices intended for series connection in an AR switch chain. Check this in the instructions of the device in question.
A maximum of 20 safety switches are allowed to be operated in a switch chain.
Important!
Ì The user is responsible for the proper integration of the device into a safe overall system. For this
purpose, the overall system must be validated, e.g. in accordance with ENISO13849-2.
Ì It is only allowed to use components that are permissible in accordance with the table below.

3. Description of the safety function
Devices from this series feature the following safety functions:
Monitoring of the safety guard position (interlocking device according to ENISO14119)
Ì Safety function:
- The safety outputs are switched off when the safety guard is open (see chapter 6.4. Switching states on page 7).
Ì Safety characteristics: category, Performance Level, PFH
D
(see chapter 12. Technical data on page 25).
4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void.
5. General safety instructions
Safety switches fulll personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly
Ì after any setup work Ì after the replacement of a system 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
Danger to life due to improper installation or due to bypassing (tampering). Safety components fulll a personal protection function.
Ì Safety components must not be bypassed, turned away, removed or otherwise rendered ineffec-
tive. On this topic pay attention in particular to the measures for reducing the possibility of bypass­ing according to ENISO14119:2013, section 7.
Ì The switching operation must be triggered only by actuators designated for this purpose. Ì Prevent bypassing by means of replacement actuators (only for multicode evaluation). For this
purpose, restrict access to actuators and to keys for releases, for example.
Ì Mounting, electrical connection and setup only by authorized personnel possessing the following
knowledge:
- specialist knowledge in handling safety components
- knowledge about the applicable EMC regulations
- knowledge about the applicable regulations on occupational safety and accident prevention.
Important!
Prior to use, read the operating instructions and keep these in a safe place. Ensure the operating instructions 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 operating instructions. You can download the operating instruc­tions from www.euchner.com.

6. Function
The safety switch monitors the position of movable safety guards. The safety outputs are switched on/off when the actuator is moved to/removed from the operating distance.
The system consists of the following components: coded actuator (transponder) and switch.
Whether the device learns the complete actuator code (unicode) or not (multicode) depends on the respective version.
Ì Devices with unicode evaluation: The actuator must be assigned to the safety switch by a teach-in operation so that
it is detected by the system. This unambiguous assignment ensures a particularly high level of protection against tam­pering. The system thus possesses a high coding level.
Ì Devices with multicode evaluation: Unlike systems with unique code detection, on multicode devices a specic 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 taught-in code in the safety switch (unique code detection). The system possesses a low coding level.
When the safety guard is closed, the actuator is moved towards the safety switch. When the switch-on distance is reached, power is supplied to the actuator by the switch and data is transferred.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the safety guard is opened.
In the event of a fault in the safety switch, the safety outputs are switched off and the DIA LED illuminates red. The occurrence of faults is detected at the latest on the next demand to close the safety outputs (e.g. on starting).
6.1. Door monitoring output
The door monitoring output is switched on as soon as a valid actuator is detected in the operating range.
6.2. Diagnostics output
The diagnostics output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.3. Limit-range monitoring
If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance. The device recognizes this situation and indicates that the actuator is in the limit range by ashing the STATE LED. This allows the safety door to be readjusted in time. Also see chapter 11. System status table CES-I-AR-… on page 24.
6.4. Switching states
The detailed switching states for your switch can be found in the system status table. All safety outputs, monitoring outputs and display LEDs are described there.
Safety guard closed
(actuator in the operating distance and permissi-
ble code detected)

Note the following points:
Ì Actuator and safety switch must be easily accessible for inspection and replacement. Ì Actuator and safety switch must be tted so that
- the front faces are at the minimum switch-on distance 0.8xSao or closer when the safety guard is closed (see chapter
12. Technical data, sections Operating distances and Typical operating distance of the respective actuator). To avoid entering the area of possible side lobes, a minimum distance is to be maintained in case of a side approach direction. See chapter 12. Technical data, section Typical operating distance for the related actuator.
- when the safety guard is open up to the distance Sar (assured switch-off distance), 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.

9. Electrical connection
The following connection options are available:
Ì Separate operation Ì Series connection with Y-distributors or the passive distribution module AC-DP-…-SA-… from EUCHNER (only with M12
plug connector)
Ì Series connection, e.g. with wiring in the control cabinet Ì Operation on an AR evaluation unit.
WARNING
In case of an error, loss of the safety function through incorrect connection.
Ì To ensure safety, both safety outputs must always be evaluated. Ì Monitoring outputs must not be used as safety outputs. Ì Lay the connection cables with protection to prevent the risk of short circuits.
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection.
Ì Do not use a control system with pulsing or switch off the pulsing function in your control system.
The device generates its own test pulses on the safety outputs. A downstream control system must tolerate these test pulses, which may have a length of up to 1ms. The test pulses are also output when the safety outputs are switched off. Depending on the inertia of the downstream device (control system, relay, etc.), this can lead to short switching processes.
Ì 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.
Ì All the electrical connections must either be isolated from the mains supply by a safety transformer
according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures (PELV).
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. RC interference suppression units must not be used.
Ì 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.
Ì To avoid EMC interference, the physical environmental and operating conditions at the in-
stallation site of the device must comply with the requirements according to the standard EN60204-1:2006, section 4.4.2 (EMC).
Ì Please pay attention to any interference elds in case of devices such as frequency converters or
induction heating systems. Observe the EMC instructions in the manuals from the respective man­ufacturer.
Important!
If the device does not appear to function when operating voltage is applied (e.g. green STATE LED does not ash), the safety switch must be returned unopened to the manufacturer.

1. Select the corresponding section in the column n (max. number of switches). Here: six switches.
2. In column IOD (possible output current per channel FO1A/FO1B), nd a current greater than or equal to 75mA. Here: 100mA.
¨ It is then possible to determine the maximum cable length from the last switch (#6) to the control system from column
l1. Here: a length of 50m is permitted.
Result: The desired cable length l1 of 40m is below the permitted value from the table. The overall length of the switch chain l
max
of 140m is less than the maximum value of 200m.
¨ The planned application is therefore functional in this form.

9.8. Connection of a single AR device
If a single AR device is used, connect the device as shown in Figure 3. Monitoring outputs can be routed to a control system.
The switch can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 seconds. The RST input must be connected to 0 V if it is not used.
WARNING
In case of an error, loss of the safety function through incorrect connection.
Ì To ensure safety, both safety outputs (FO1A and FO1B) must always be evaluated.
Important!
The 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. Detailed application examples can be found at www.euchner.com. Simply enter the order number in the search box.

9.9. Connection of several devices in a switch chain
Important!
Ì An AR switch chain may contain a maximum of 20 safety switches. Ì The example shows only an excerpt that is relevant for connection of the CES system. The exam-
ple illustrated here does not show complete system planning. The user is responsible for safe in­tegration in the overall system. Detailed application examples can be found at www.euchner.com. Simply enter the order number in the search box. You will nd all available connection examples for the device in Downloads.
The series connection is shown here based on the example of the version with plug connectors M12. The switches are con­nected one behind the other with the aid of pre-assembled connection cables and Y-distributors. If a safety door is opened or if a fault occurs on one of the switches, the system shuts down the machine. A higher-level control system cannot, however, detect which safety guard is open or on which switch a fault has occurred with this connection technology. A special AR eval­uation unit is required for this purpose (see chapter 9.10. Information on operation on an AR evaluation unit on page 20).
The series connection can also be realized via additional terminals in a control cabinet.
The safety outputs are permanently assigned to the respective safety inputs of the downstream switch. FO1A must be routed to FI1A and FO1B to FI1B. If the connections are interchanged (e.g. FO1A to FI1B), the device will switch to the fault state.
Always use the RST input in series connections. All switches in a chain can be reset at the same time with this reset input. To do this, a voltage of 24 V must be applied to the RST input for at least 3 seconds. If input RST is not used in your appli­cation, it should be connected to 0 V.
Note the following on this aspect:
Ì A common signal must be used for all switches in the chain. This can be a changeover switch or the output of a control
system. A button is not suitable because the reset must always be connected to GND during operation (see switch S1 in Figure 4 on page 19).
Ì Reset must always be performed simultaneously for all switches of the chain.

9.10. Information on operation on an AR evaluation unit
The devices can be operated on an AR evaluation unit. Please refer to the operating instructions for the relevant AR evalu­ation unit for more information.
9.11. Notes on operation with safe control systems
Please observe the following requirements for connection to safe control systems:
Ì Use a common power supply for the control system and the connected safety switches. Ì A pulsed power supply must not be used for U
B
. Tap the supply voltage directly from the power supply unit. If the supply
voltage is connected to a terminal of a safe control system, this output must provide sufcient electrical current.
Ì Always connect inputs FI1A and FI1B directly to a power supply unit or to outputs FO1A and FO1B of another EUCHNER
AR device (series connection). Pulsed signals must not be present at inputs FI1A and FI1B.
Ì The safety outputs (FO1A and FO1B) can be connected to the safe inputs of a control system. Prerequisite: The input
must be suitable for pulsed safety signals (OSSD signals, e.g. from light curtains). The control system must tolerate test pulses on the input signals. This normally can be set up by parameter assignment in the control system. Observe the notes of the control system manufacturer. For the test-pulse duration of your safety switch, please refer to chapter 12. Technical data on page 25.
A detailed example of connecting and setting the parameters of the control system is available for many devices at www.euchner.com in the area Download » Applications » CES. The features of the respective device are dealt with there in greater detail.

10.1. LED displays
You will nd a detailed description of the signal functions in chapter 11. System status table CES-I-AR-… on page 24.
LED Color
STATE green
DIA red
10.2. Teach-in function for actuator (only for unicode evaluation)
The actuator must be allocated to the safety switch using a teach-in function before the system forms a functional unit.
During a teach-in operation, the safety outputs and the monitoring output OD are switched off, i.e. the system is in the safe state.
Tip!
It is recommended to perform the teach-in operation prior to mounting. Mark switches and actuators that belong together in order to avoid confusion. For devices to be connected in series, we recommend performing the teach-in operation separately for each device prior to series connection.
Important!
Ì The teach-in operation may be performed only if the device functions awlessly. The red DIA LED
must not be illuminated.
Ì The safety switch disables the code of the previous actuator if teach-in is carried out for a new
actuator. Teach-in is not possible again immediately for this actuator if a new teach-in operation is carried out. The disabled code is released again in the safety switch only after a third code has been taught.
Ì The safety switch can be operated only with the last actuator taught. Ì The number of teach-in operations is unlimited. Ì If the switch detects the actuator that was most recently taught when in teach-in standby state,
this state is ended immediately and the switch changes to normal state.
Ì If the actuator to be taught in is within the operating distance for less than 60s, it will not be acti-
vated and the most recently taught in actuator will remain saved.
10.2.1. Preparing device for the teach-in operation and teaching in actuator
1. Apply operating voltage to the safety switch.
¨ The green LED ashes quickly (approx. 5Hz)
A self-test is performed during this time (approx. 8s). After this, the LED ashes cyclically three times and signals that it is in standby state for teach-in. Standby state for teach-in remains active for approx. 3 minutes.
2. Move new actuator to the read head (observe distance < Sao).
¨ Teach-in operation starts, green LED ashes (approx. 1 Hz). During teach-in, the safety switch checks whether the actuator
is a disabled actuator. If this is not the case, the teach-in operation is completed after approx. 60 seconds, the green LED goes out. The new code has been saved, the old code disabled.
3. To activate the new actuator code from the teach-in operation in the safety switch, the operating voltage to the safety switch must then be switched off for min. 3 seconds.

10.2.2. Teach-in function with series connection, replacing and teaching in device
It is recommended not to teach in the actuators in the series connection but to teach them in one by one instead. Teach-in in a series connection works analogously to separate operation in principle. All switches in the chain can be taught in at the same time. The prerequisite is that the switch chain functions without problems and the following steps are followed. Further steps might have to be observed for mixed switch chains (e.g. for chains with CES and safety switches with guard locking). Observe the operating instructions for the other devices in the chain for this purpose.
Work on the wiring (e.g. during device replacement) should generally be performed in a de-energized state. On certain systems, it is nevertheless necessary to perform this work and subsequent teach-in during ongoing operation.
Input RST must be connected as shown in Figure 4 on page 19 to permit this.
Proceed as follows:
1. Open the safety guard on which the switch or actuator is to be replaced.
2. Mount the new switch or actuator and prepare it for the teach-in operation (see chapter 10.2.1. Preparing device for the teach-in operation and teaching in actuator on page 22).
3. Close all safety guards in the chain.
4. Actuate the reset for at least 3s (24V on RST).
¨ On the safety switch that is positioned at a new actuator, the green LED ashes at approx. 1Hz and the actuator is
taught in. This takes approx. 1min. Do not switch off during this time and do not actuate reset! The teach-in operation has ended when all LEDs on the device are off.
5. Actuate the reset for at least 3s (24V on RST).
¨ The system restarts and then continues to function in normal operation.
10.3. Functional check
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 persons in the danger area. Ì Observe the valid accident prevention regulations.
10.3.1. Electrical function test
After installation and any fault, the safety function must be fully checked. Proceed as follows:
1. Switch on operating voltage.
¨ The machine must not start automatically.
¨ The safety switch carries out a self-test. The green STATE LED ashes for 8s at 5Hz. The green STATE LED then ashes
at regular intervals.
2. Close all safety guards.
¨ The machine must not start automatically.
¨ The green STATE LED illuminates 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 ashes at regular intervals.
Repeat steps 2-4 for each safety guard.

12.1.1. Typical system times
Please refer to the technical data for the exact values.
Ready delay: After switching on, the device carries out a self-test. The system is ready for operation only after this time.
Switch-on time of safety outputs: The max. reaction time ton is the time from the moment when the actuator is in the
operating distance to the moment when the safety outputs switch on.
Simultaneity monitoring, safety inputs FI1A/FI1B: If the safety inputs have different switching states over a certain time, the safety outputs (FO1A and FO1B) will be switched off. The devices switches to fault state.
Risk time according to EN 60947-5-3: If an actuator moves outside the operating distance, the safety outputs (FO1A and FO1B) are switched off after the risk time at the latest.
If several devices are operated in a series connection, the risk time of the overall device chain will increase with each device added. Use the following calculation formula:
tr=t
r,e
+(nxtl)
tr = Total risk time
t
r,e
= Risk time, single device (see technical data)
tl = Risk time delay per device
n = Number of additional devices (total number -1)
Discrepancy time: The safety outputs (FO1A and FO1B) switch with a slight time offset. They have the same signal state no later than after the discrepancy time.
Test pulses at the safety outputs: The device generates its own test pulses on the safety outputs (FO1A and FO1B). A downstream control system must tolerate these test pulses.
This can usually be set up in the control systems by parameter assignment. If parameter assignment is not possible for your control system or if shorter test pulses are required, please contact our support organization.
The test pulses are also output when the safety outputs are switched off.
