scope of delivery.
Application
The "AS-i Safety Relay Output Module with Diagnostic Slave and 1 EDM in-
put" is a decentralized output module for safe control of actuators in the
safety bus system AS-i Safety at Work (SaW).
The module SOM-4E-0A-C1 is controlled by a safety monitor respectively a
gateway with integrated safety monitor.
A special characteristic of the module is its two types of AS-i addresses:
- Safe AS-i address
SOM-4E-0A-C1 monitors to the communication on the safe address and switch-
es based on the data listened in.
- Not safety-related AS-i address
The not safety-related AS-i address is used for diagnosis and for PLC-controlled
switching.
All SaW output modules with the same safe AS-i adress are switching simulta-
neously.
The module SOM-4E-0A-C1 is certified according to EN 62 061, SIL 3 and
EN 13 849, Performance Level e.
Safety characteristics
1. The specified PFD and PFH
D
values refer to the maximum power-on time of
12 months and a maximum service life of 20 years, according to EN ISO 13 849-1.
The maximum cycle time of the module (also under the assumption of errors) is
50 ms from the concern of the code sequence to the shutdown of the relay.
In addition to the reaction time of the monitor and of the inputs must also be con-
sidered.
Safety Requirements
• In the device two relays connected in series and positively-driven are used.
• If one of the two relays is not switching (e.g. for stuck contact), the module will re-
cognize this.
• The contact sets 1.13/1.23 and 1.14/1.24 are realized with the same relays and not
independent.
• 1.13, 1.23, 1.14, 1.24 are potential-free contacts without cross-circuit monitoring.
• If two independent contactors connected in series are to be controlled with the de-
vice, it is to be ensured that the line between the contactors and the device can get
no connection to another potential to prevent an unwanted switching-on of the con-
tactors.
• The input 1.Y1 is – as well I1 ... I3 – a standard AS-i input.
Assembling
Disassembling
The module is mounted on 35 mm standard rails acc. to DIN EN 50 022.
For assembling, position the device on the upper edge of the standard rail and
snap it onto the bottom edge then.
Maintenance
The proper function of the AS-i Safety Relay Output Module within the system to
be secured, i.e. the safe shutdown following the triggering of an assigned safe
sensor or switch, is to be checked at least annually by the safety officer.
Programming of the safety-related AS-i address
1. Move the switch of the device to PRG.
2. Set the requested address using a handheld programming device or an AS-i mas-
ter.
3. Check the programmed address using a handheld programming device or an AS
-i
master.
4. Check the ID code of the slave using a handheld programming device or an AS
-i
master. The code should be „F“.
5. Check the ID1 code of the slave using a handheld programming device or an AS
-i
master. The code should correspond to the tens digit of the address.
6. Check the ID2 code of the slave using a handheld programming device or an AS
-i
master. The code should correspond to the digit of the address.
7. Check the IO code of the slave using a handheld programming device or an AS
-i
master. The code should be „7“.
8. If all the steps from 3 to 7 were correctly, please continue with step 9. Otherwise
repeat from step 1 again.
9. Move the switch of the device to RUN.
Programming of the not safety-related AS-i address
The address can be set using a handheld programming device in RUN-position of the
switch.
Specified normal operation of the module:
The AS-i Safety Relay Output Module is a decentralized output module
for safe control of actuators in the security bus system AS-i Safety at
Work (SaW).
For connection and commissioning of the SaW module the knowledge
is assumend of the connecting und operating instructions as well as op-
erating instructions of ASIMON configuration and diagnostic software
(see accessories – ordering information).
Person protective function:
SaW modules integrated in the Safety bus systems AS-i safety at Work
fulfill a person protective function. Inappropriate installation puts the
function in risk! The manufacturer of the machine/plant at that one the
safety related devices is used is responsible for the correct and safe to-
tal function of all single safety components! Depending on the choice of
safety components to be used the safety system as a whole may also
be assigned to a lower safety category.

Control and indicating elements, configuration
See and ration software>. Ensure appropiate installation: Electrical installation is to be performed by trained expert personnel. During installation care must be taken that supply and signal leads and also the AS-i bus cable are laid separately from power cables. In the switchgear cabinet it must be ensured that appropriate spark-quenching equipment is used with contactors. Where drive motors and brakes are used, attention must be paid to the installation instructions in the corre- sponding operating instructions. Please note that the maximum line length of the AS-i bus cable is 100 m. Cables above that length require the use of a suitable circuit extension. It is essential to adhere to the prescribed fusing; this is the only way of guaranteeing safe disconnection in the case of a fault. This is to be performed by activating each safe AS-i slave at least once per year and visually inspecting the switching behaviour of the output circuits of the AS-i safety monitor. The maximum switch-on time and total operating time depends on the PFD value selected for the overall failure probability. When the maximum switch-on time has been reached (three, six or twelve months), the safety system must be checked to ensure that it is functioning correctly by prompting the shutdown function. When the total operating time has been reached (20 years), the device must be checked at the manufacturer's factory to ensure that it is func- tioning correctly. The proper safety function of the device must be verified in the asset in any case!
