Correct Use

The Coded Electronic Safety switches series CES are safety devices for monitor-

ing 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:

Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.

General principles for design

Ì EN ISO 14121-1, Safety of machinery. Risk assessment. Principles

Ì IEC 62061, Safety of machinery – Functional safety of safety-related electrical,

electronic and programmable electronic control systems.

General Safety Instructions

Safety switches fulfill personal protection functions. Incorrect installation or tamper-

ing 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!

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 pos-

sibility 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.

Important!

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

¨ 1 read head

CES-AZ-AES-02B

¨ 2 read heads

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.

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.

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).

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 main-

tained 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

ar

, the safety outputs are safely shut

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

ao

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.

Ì when the safety guard is open up to the distance S

ar

(assured switch-off dis-

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.

Operating Instructions Safety System CES-AZ-AES-…

Electrical Connection

Warning!

In the event of a fault, loss of the safety function due to incorrect connection.

Ì Monitoring outputs must not be used as safety outputs.

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 ap-

plies 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 pur-

pose.

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

B

is reverse polarity protected.

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.

Fusing of the power supply and the safety

contacts

Ì Provide external contact fuses (6 A gG fuse or 6 A circuit breaker, characteris-

tic B or C) for relay outputs.

Ì The power supply must be protected with a max. 8 A fuse before terminal U

B

.

Commissioning

LED indicators

STATE LED green State display (multifunction display using flashing modes)

OUT LED yellow Safety circuit closed

DIA LED red — Operating error or

— External fault (fault in the feedback loop) or

— Teach-in process not valid or

— Internal device fault or

— TST input activated (function test active)

Teach-in operation

Before the system forms a function unit, the parameters are set in the evaluation

unit in a teach-in operation (number of connected read heads, assignment of

the actuators to the read heads, with or without automatic start, with or without

feedback loop). In this process, the read heads are activated and the actuator

code is learned.

These configuration parameters are saved in the non-volatile memory in the evalu-

ation unit.

The safety outputs are open during the teach-in operation. The system is in a safe

state.

Important!

Ì During the teach-in operation 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 teach-in

operation must be repeated.

Ì The number of teach-in operations is unlimited. The evaluation unit can be

re-configured as often as required.

Ì Actuators cannot be interchanged without a renewed teach-in operation.

Ì An actuator that has not been subjected to teach-in will not be detected by

the related read head.

Ì Even if only one new actuator needs to be taught, a complete new teach-in

operation must be carried out as described in the section Setup.

Ì Do not change DIP switches during operation.

3. Set required configuration on machine

Ì Close all doors to be monitored (the actuators must be in the operating

distance of the related read head)

Ì For Manual start operating mode: Keep start button closed

Ì For With feedback loop operating mode: keep feedback loop closed

4. Start teach-in operation

Ì Switch on operating voltage

Ì Wait for self-test (STATE LED flashes for approx. 10 seconds at 15 Hz)

Ì Teach-in operation starts (STATE LED flashes at approx. 1 Hz)

Ì Wait for acknowledgement of the teach-in operation (STATE LED goes out

after approx. 10 seconds)

5. End teach-in operation

Ì Remove jumper between J1 and J2

(for CES-AZ-AES-01B between J and 0V)

Ì For Manual start operating mode: Start button must be connected

Ì For With feedback loop operating mode: Feedback loop must be

connected

Ì Press reset button or interrupt operating voltage for at least 10 seconds

Ì Wait for self-test (STATE LED flashes for approx. 10 seconds at 15 Hz)

6. Check all safety guards for effectiveness

Changing the configuration / new actuator

The evaluation unit can be re-configured as often as required. For this purpose you

must proceed as per the first teach-in operation according to the Setup procedure

section.

Faulty actuators can be replaced. Then a complete teach-in operation must be

performed as per the section Setup. The number of teach-in operations is unlimited.

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 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 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.
