General safety instructions

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!

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.

Important:

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. You can download
the operating instructions from www.EUCHNER.de.

Operating Instructions Safety System CES-AZ-ALS-...

Function

The safety system CES-AZ-ALS... meets 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 non-contact safetysystem CES 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-ALS-01B

CES-AZ-ALS-02B

CES-AZ-ALS-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 orO1...O2 or O1...O4 (semiconductor
outputs, n-switching) on the related read head are set LOW . 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.

¨ 1 read head

¨ 2 read heads

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 LOW and the DIA LED illuminates red.

The device can be reset using the Reset button.

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.
This distance enables the 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

Electrical connection

Warning!

In case of an error, loss of the safety function through incorrect connection.

Ì Door 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 EN 61558-2-6 with limited output volt­age in the event of a fault, or by other equivalent isolation measures.

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 min.

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

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

OUT Yellow LED Safety circuit closed

DIA LED red - Operating fault 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)

A detailed description of the LED indicators can be found in the section System

status table page 18.

Teach-in operation

Important:

Before the system forms a functional unit, the parameters are set in the evaluation
unit using 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). During this process the read heads are activated and the actuator
code taught-in.

These configuration parameters are saved in the non-volatile memory in the evalu­ation unit.

During the teach-in operation the safety outputs are open. The system is in the
safe state.

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.

To trigger a teach-in operation, the user must perform the following actions in the
stipulated order:

1. Prepare for teach-in operation

Ì Power supply U

is to be switched off

B

Ì Fit a jumper between terminals J1 and J2 (for CES-AZ-ALS-01B between J

and 0V)

Tip!

5. End teach-in operation

Ì Remove jumper between J1 and J2 (on CES-AZ-ALS-01B between J and 0V)
Ì For operating mode Manual start: start button must be connected
Ì For operating mode With feedback loop: feedback loop must be con-

nected

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.

After acknowledging the teach-in operation you can use the monitoring outputs O1
... O4 for the diagnostics. All actuators that are in the operating distance of a read
head at this time are signaled on the related monitoring output. In the case of an
fault you can quickly see which actuators have not been detected, e. g. because it
has been forgotten to close a safety door prior to teach-in.

This function is only available during setup.

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 10 seconds with 15 Hz.
The STATE LED then illuminates 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 illuminates continuously; the OUT and ERROR LEDs do

not illuminate.

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 unit 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 LOW as a monitoring
function.

When the test input TST is reset, the evaluation unit resets the diagnostic output
DIA to HIGH, the red LED switches off and normal operation continues.

16

Operating Instructions Safety System CES-AZ-ALS-...

In Manual start operating mode, the start button must be pressed again to start
the system.

Important:

After the self-test the test input TST must be set or connected to 0 V.

Internal component failure or actuator CES-A-BMB in the inadmissible range or excessively high external
interference (EMC)

Configuration fault:

Teach-in operation must be performed again

Possible causes:

- State change during the teach-in operation

- The DIP switch setting and the configuration did not match during the teach-in operation

- DIP switch setting has been changed without teach-in 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.
As a result the feedback loop cannot be closed in this short time. Note the release time for the monitored
contactor.

- Feedback loop was not closed on starting the evaluation unit.

The read heads CES-A-LNN and CES-A-LSP have an integrated LED for the indication
of the door position. The LED illuminates with the safety guard closed.
