Operating Instructions
Evaluation Unit CES-A-.1B-01B-AS1
Setup/teach-in function for new
actuator
The actuator must be assigned to the evaluation unit
using a teach-in function before the system forms a
functional unit. During a teach-in operation, the code
sequence 0000 is sent over the AS-Interface bus,
i.e. the system is in the safe state.
Teach-in function for first actuator (delivery
state)
1. Connect the device to the AS-Interface bus
Green LED flashes fast (approx. 4 Hz)
f
2. Move actuator toward the read head (observe
distance < S
)
ao
Teach-in operation starts, green LED flashes
f
slowly (approx. 1 Hz)
3. Teach-in operation completed (after 60 sec-
onds)
Green LED goes out
f
4. To activate the actuator code from the teach-in
operation in the evaluation unit, the evaluation
unit must then be isolated from the AS-Inter-
face bus for min. 10 seconds.
Teach-in function for a new actuator
1. Connect the device to the AS-Interface bus
2. Move new actuator toward the read head
(observe distance < S
)
ao
Teach-in operation starts, green LED flashes
f
(approx. 1 Hz)
3. Teach-in operation completed (after 60 sec-
onds)
Green LED goes out, new code saved, old
f
code deactivated
4. To activate the actuator code from the teach-in
operation in the evaluation unit, the evaluation
unit must then be isolated from the AS-Inter-
face bus for min. 10 seconds.
Repeated teach-in of the same actuator on the
f
same evaluation unit is not possible.
The number of valid teach-in operations on one
f
evaluation unit is limited to a maximum of 8.
The evaluation unit can only be operated with the
f
last actuator taught-in.
A teach-in operation is invalid if:
f
- the teach-in operation is canceled before the
green LED goes out
- the power supply was switched off during the
teach-in operation.
NOTICE
After the 8th teach-in operation or if an old actu-
ator is placed against the read head, the system
switches to the teach-in mode automatically. In
both cases, a teach-in operation with a duration of
60 seconds is started but the last actuator code
remains active in the memory (see Table 1 System
states). A new code is not taught-in.
Addressing
The device address can be set using either the
AS-Interface safety bus or using the addressing
socket on the device.
Important!
If you use the addressing socket for setting the
address, you must first remove the actuator
from the read area, otherwise the CES...AS1
will indicate an error.
Configuration in the AS-Interface
safety monitor
(see operating instructions for the AS-Interface
safety monitor)
The safety switch is configured in the AS-Interface
safety monitor with the set AS-Interface address as
follows, for example:
Dual-channel dependent
f
Without start-up test
f
Synchronization time = 0.5 second
f
Function test
WARNING
Fatal injury due to faults during the function test.
Before carrying out the function test, make sure
f
that there are no persons in the danger area.
Observe the valid accident prevention regula-
f
tions.
Check the device for correct function after installa-
tion and after every fault.
Proceed as follows:
1. Switch on operating voltage.
2. Close all guards.
The machine must not start automatically.
¨
3. Start the machine function.
4. Open the guard.
The machine must switch off and it must not be
¨
possible to start it as long as the guard is open.
Repeat steps 2 - 4 for each guard.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
If damage or wear is found, the complete device
f
must be replaced. Replacement of individual
parts or assemblies is not permitted.
No servicing is required on the battery-less actuator.
Inspection of the following is necessary to ensure
trouble-free long-term operation:
Correct switching function
f
Secure fastening of all components (use of the
f
safety screws supplied)
Damage, heavy contamination, dirt and wear
f
Sealing of cable entry
f
Loose cable connections or plug connectors.
f
Check of the release distance
f
Info: The year of manufacture can be seen in the
bottom right corner of the type label.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety regula-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.

Notes on UL requirements
This device is intended to be used with a Class 2
power source in accordance with UL1310.
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 combina-
tion 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.
