2. Correct use
Evaluation units of series CES-AZ serve to evaluate safety-related safety signals from EUCHNER read heads. Depending on
the read heads used, the system can form an interlocking device with or without guard locking. The system complies with
the requirements according to ENIEC60947-5-3.
The following applies in combination with a CES or CEM read head:
The system consists of evaluation unit, read head and actuator. It forms an interlocking device with high coding level
(type4).
In combination with a movable safety guard and the machine control, this system 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:
ÌStarting commands that cause a dangerous machine function must become active only when the safety guard is
closed.
ÌOpening the safety guard triggers a stop command.
ÌClosing a safety guard must not cause automatic starting of a dangerous machine function. A separate start com-
mand must be issued. For exceptions, refer to EN 12100 or relevant C-standards.
The following applies in combination with a CET read head:
The system comprising evaluation unit, read head with guard locking and actuator forms an interlocking device with
guard locking with high coding level (type4).
In combination with a movable safety guard and the machine control, this system prevents the safety guard from
being opened while a dangerous machine function is being performed.
This means:
ÌStarting commands that cause a dangerous machine function must become active only when the safety guard is
closed and locked.
ÌThe guard locking device must not be unlocked until the dangerous machine function has ended.
Closing and locking 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 12100 or relevant C-standards.
Before use, a risk assessment must be performed on the machine, e.g. in accordance with the following standards:
ÌENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design

3. Description of the safety function
Devices from this series feature the following safety functions:
The following applies in combination with read heads without guard locking (CES read heads) and read heads with guard
locking for process protection (CEM read heads):
Monitoring of the safety guard position
(interlocking device according to EN ISO 14119)
ÌSafety function:
- The safety contacts are switched off when the safety guard is open (see chapter 6. Technical data on page 20).
ÌSafety characteristics: category, Performance Level, PFHd(see chapter 6. Technical data on page 20).
The following applies in combination with read heads with guard locking (CET-AX):
Monitoring of guard locking and the position of the safety guard
(interlocking device with guard locking according to EN ISO 14119)
ÌSafety function (see chapter 6. Technical data on page 20):
- The safety contacts are switched off when guard locking is unlocked (monitoring of the locking device).
- The safety contacts are switched off when the safety guard is open.
- Guard locking can be activated only when the actuator is located in the switch head (failsafe locking mechanism).
ÌSafety characteristics: category, Performance Level, PFHd(see chapter 6. Technical data on page 20).
Control of guard locking
ÌIf the device is used as guard locking for personnel protection, control of guard locking must be regarded as a safety
function.
ÌThe device does not feature a safety characteristic for control of guard locking, because the guard locking solenoid is
completely disconnected from the outside (no control function within the device). It therefore does not contribute to the
failure probability.
ÌThe safety level of guard locking control is determined exclusively by the external control (e.g. PFHdext. of the standstill
monitor).

6. Function
The safety system consists of three components:
ÌCoded actuator
ÌRead head
ÌEvaluation unit
The number of read heads that can be connected depends on the evaluation unit:
ÌCES-AZ-AES-01B 1 read head
ÌCES-AZ-AES-02B 2 read heads
ÌCES-AZ-AES-04B 4 read heads
The evaluation unit can be congured so that a start button (monitoring of the falling edge) and a feedback loop for moni-
toring external relays and contactors can be connected. The individual conguration is dened by a setup procedure (see
chapter 9. Setup on page 16).
The read heads and actuators are assigned to the device in a special teach-in operation.
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 xed part of the safety guard and are each connected to the evaluation unit via a two-
core screened cable (terminals H.1, H.2 and SH.).
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 read-in code is compared with the taught-in code 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 to 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 feed-
back 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
redundantly controlled safety outputs, the evaluation unit will enter the safe state with every detectable fault.
When a safety guard is opened or a guard locking device is unlocked, 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 to HIGH
and the DIA LED illuminates red.
