About this manual

This manual is valid for all field evaluation units CES-FD-AP-M-01-… (Multicode) and CES-FD-AP-U-01-… (Unicode).

Correct use

The field evaluation units series CES are safety devices for monitoring movable safety guards.
The complete safety system consists of three components:
coded actuator (transponder), read head and field evaluation unit.
- In combination with a separating safety guard and the machine control, this safety system 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 components are used, a risk assessment must be performed on the machine, e. g., in accordance with:
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì EN ISO 12100, Safety of machinery – General principles for design – Risk as-
sessment and risk reduction
Ì 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, for example
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì 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. General
requirements
Ì EN 60947-5-3, Specification for low-voltage switchgear and controlgear. Con-
trol circuit devices and switching elements. Requirements for proximity devices with defined behavior under fault conditions
The unit must be used only in conjunction with the CES read heads and CES ac­tuators from EUCHNER. On the use of different actuators, EUCHNER provides no warranty for safe function.

Important!
Ì The user is responsible for the 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 In the estimation of the PL for the overall system, a maximum value of 100
years can be assumed for the MTTFd according to the limit value in EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value for the PFHd of 2.47x10-8/h.
Ì Correct use requires observing the permissible operating parameters (see
Technical data).
Ì 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.
Ì It is only allowed to use components that are permissible in accordance with
the table below.

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.

General safety instructions

Safety switches fulfill 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 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 and ac-
cident prevention
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. If you should lose the operating instructions, you can download this document from www.EUCHNER.de.

Function

Field evaluation units series CES-FD-AP make it possible to evaluate CES read heads in the field. The safety outputs on the field evaluation units are connected to the machine control.
The system meets the following safety requirements:
Ì Safety category 4, PLe according to EN ISO 13849-1 Ì Redundant design of the circuit in the unit with self-monitoring Ì This means that the safety system still functions even if an internal component
fails
Ì The switch state of the semiconductor outputs is continuously monitored inter-
nally
Ì Short circuit detection at the safety outputs by pulsed signals
The following switch-on condition applies for the safety outputs FO1A and FO1B (see also System state table and section Typical system times):
Ì Safety guard closed
The system consists of three components: coded actuator (transponder), field evaluation unit and read head.
The read head is connected to the field evaluation unit and reads the actuator code.
Every EUCHNER actuator supplied has an electronic coding (unique coding) that is read by the read head. Only if a correct coding is detected does the system accept the actuator. The code in an actuator cannot be reprogrammed.
Unlike systems with unique code detection, on multicode systems 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 safety switch (unique code detection).
The read head is fastened to the fixed part of the safety guard.
The actuator attached to the movable part of the safety guard is moved towards the read head by closing the door. The read head is connected to the field evaluation unit. When the switch-on distance is reached, power is supplied to the actuator by the read head by induction and data can be transferred.
If a permissible code is detected, the safety outputs are released.
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 safety switch 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 monitoring output OD (optional) is switched off. The state of the safety outputs is monitored internally by two microprocessors.
If faults are detected, the safety circuit is switched off and the DIA LED illuminates. In case of devices with a monitoring output OI, the output is switched on.
The field evaluation unit has a redundant switching design with self-monitoring. This means that the safety system is still effective even if a component fails.
The system is designed so that failures will not result in the loss of the safety func­tion. The occurrence of failures is detected by cyclic self-monitoring at the latest on the next demand to switch on the safety outputs (e.g. on starting).
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. This allows the safety door to be readjusted in time.

Electrical connection

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.
Ì Monitoring outputs 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 The device generates its own clock signal on the output lines FO1A/FO1B. A
downstream control system must tolerate these test pulses, which may have a duration of up to 0.4 ms. No pulses are output when the safety outputs are switched off.
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 The device tolerates voltage interruptions in the operating voltage U
to 5 ms. Voltage interruptions at UB are also output on the safety and moni­toring outputs.
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. 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 In order to avoid EMC interference, the physical environmental and operating
conditions at the installation site of the device must comply with the require­ments according to the standard EN 60204-1:2006, section 4.4.2 (EMC).

Particularities for operation on decentralized pe­ripheral systems
The version CES-FD-AP-…-.SI-… (M12, 5-pin; pin 5 not assigned) is optimized for connection to decentralized peripheral systems, such as the ET200 series from Siemens. The devices are connected like an OSSD (e.g. like light curtains).
The 5-pin M12 plug connector can be connected directly to the socket of an IP65 field module (e.g. ET200pro) with aid of the connection cables on page 25. If flying leads are used, connection to IP20 input and output modules (e.g. ET200s) is naturally also possible.
Important!
Observe the following notes prior to connection:
Ì Parameter assignment might be required for the input/output modules (see
application example at www.EUCHNER.de, in the area Download Applica­tionen CES).
Ì Additionally observe notes from the control system manufacturer where nec-
essary.

Teach-in function for actuator (only version Unicode)

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 (op­tional) are in a high-resistance state, i.e. the system is in the safe state.
Normal operation: Door closed
- Door open
- Actuator in the limit range (further signal functions see status table)
- Internal electronics fault
- Fault at the inputs/outputs
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 deleted again in the safety switch only after a third code has been taught.
Ì The safety switch can only be operated with the last actuator taught. Ì If the switch detects an actuator which has already been taught when in
teach-in standby state, this state is ended immediately and the switch chang­es to normal state.
Ì The actuator being taught is not activated if it is within the operating dis-
tance for less than 60 s.
Actuator teach-in
1. Apply operating voltage to the safety switch.
¨ A self-test is performed for approx. 0.5 s. After this, the LED flashes cycli-
cally 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.
¨ Teach-in operation starts, green LED flashes (approx. 1 Hz). During teach-in, the
safety switch checks whether the actuator is a disabled actuator. Provided this is not the case, the teach-in operation is completed after approx. 60 seconds, and the green LED goes out. The new code has now been stored, and the old code is 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.
15
Operating Instructions Field Evaluation Unit CES-FD-AP-.-01-…

Setup (only version Multicode)

1. Apply operating voltage to the device.
¨ The green LED flashes briefly and a self-test is performed.
After this, the LED flashes cyclically one time and signals that it is in standby state.
Warning!
2. Move actuator to the read head (observe distance < S
¨ The green LED illuminates continuously and indicates the detection of the
actuator.
If the green LED is flashing in fast flashing sequences, the actuator is in the limit range. In this case the safety guard must be re-adjusted such that the actuator is completely in the read area.

Functional check

After installation and any fault, the safety function must be fully checked. Proceed as follows:
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 STATE LED then flashes at regular intervals.
2. Close all safety guards.
Ì The machine must not start automatically.
Ì 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 LED STATE flashes at regular intervals.
Repeat steps 2-4 for each safety guard.

Typical system times
Ready delay: After switching on, the unit carries out a self-test. The system is
ready for operation only after this time (0.5 s).
Switch-on time of safety outputs: The max. reaction time from the moment when the actuator is at the operating distance (safety door closed) to the moment when the safety outputs switch on T
Risk time according to EN 60947-5-3: If an actuator moves outside the operating distance, the safety outputs FO1A and FO1B are deactivated after a maximum of 260 ms.
Difference time: The safety outputs FO1A and FO1B switch with a slight delay in relation to each other. They have the same signal state at the latest after a dif­ference time of 10 ms.
Test pulses at the safety outputs: The device generates its own clock signal on the output lines FO1A/FO1B. A downstream control system must tolerate these test pulses, which may have a duration of up to 0.4 ms.
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.
