3 Intended use
The safe AS-i module detects safety-related switching states, e.g. of 1- or 2-channel E-stops, position switches, door contacts, etc.
For this purpose, a code table is transferred via the AS-i system with 8 x 4 bits which is evaluated by the AS-i safety monitor.
When operated correctly, the system can be used in applications up to performance level e, category 4, according to EN ISO 13849-1 or IEC 61508/SIL3 (see notes Electrical connection).
Installation must be in accordance with EN 60204 and EN 62026-2. If an AS-i network is controlling a machine with potentially dangerous movements and EN 60204-1 applies, a special insulation monitoring device must also be installed.
Depending on the safety components used the complete safety system can also be classified for a lower control category.

6 Installation
6.1 Installation location
To ensure correct operation, install the device in a housing that can only be opened using a tool or in a locked control cabinet (both protection rating IP 54 or higher) as an enclosure in accordance with EN61010-1.
6.2 Installation of the device
Mount the device on a 35mm DIN rail. The mounting orientation has no adverse effect on the function.
- Leave enough space ( ≥ 50mm ) between the device and the top and bottom of the control cabinet to enable air circulation and to avoid excessive heating.
6.3 Identical devices mounted side by side
Fig. 1: Identical devices mounted side by side
6.4 Deratings for side by side mounting of identical devices
When identical units are mounted side by side with a minimum distance of 25mm , no deratings need to be observed.
When identical units are mounted side by side without any distance, derating according to the following table applies:
| Article number | Derating |
| AC009S Overall current rating of outputs when mounted side by side | |
| I [%] | |
| 100 | T [°C] |
| 90 | 01020304050607080 |
| 80 | Ambient temperature -25...50°C / linear derating 40...50°C |
| 70 | Overall current rating of outputs 50% each at 50°C corresponds to 2 x 3 A (example) |
| 60 | |
| 50 | |
| 40 | |
| 30 | |
| 20 | |
| 10 | |
6.5 Side by side mounting of different devices
| ATTENTION If units are mounted side by side, inadmissible heating may occur between the units. ► Malfunction / damage is possible. ► Take into account the internal heating of all devices when mounting different devices side by side and observe the environmental conditions for each device. |
6.6 Removing the device
7 Electrical connection
7.1 General wiring information
The unit must be connected by a qualified electrician.
- Disconnect the device from the mains supply before installation; if necessary, also disconnect any independently supplied input / output load circuits.
Observe the national and international regulations for the installation of electrical equipment.
Voltage supply according to SELV, PELV.
Do not connect the inputs with external potential.
Please observe the required precautions against electrostatic discharge.
Connect the external switching contacts for the safe inputs to the screw terminals of the connectors.
Use switching contacts with:
a current rating ≥ 1 ampere
electrically isolated contact elements
contacts which open when there is a demand on the safety function
Cable length between module and mechanical contacts ≤ 10m
WARNING
Use of unconnected terminals.
Electric shock possible.
- Do not use unconnected terminals (n.c) which are not shown in the drawing as support point terminals.
Protection guaranteed.
Touchable surfaces of the device are insulated from the AS-i circuit and from the (non-safe) relay circuits O3 and O4 with basic insulation according to IEC 61010-1 (mains circuit of overvoltage category II up to 300V nominal mains voltage).
This does not apply to connection areas (IP 20).
The (non-safe) relay circuits O3 and O4 are insulated from AS-i with reinforced insulation according to IEC 61010-1 (mains circuit of overvoltage category II up to 300V nominal mains voltage).
The (non-safe) relay circuits O3 and O4 are insulated from each other with reinforced insulation according to IEC 61010-1 (mains circuit up to 300V of overvoltage category II).
The external wiring has to be carried out in a way that ensures the required separation from other circuits.
7.2 Safety instructions relay connections
The external protection of the relay currents according to the valid regulations to the values of the technical data is the responsibility of the system manufacturer.
The relays are not designed for small switching currents. If the relay outputs are used for switching very small currents (e.g. PLC inputs), considerable contact resistance can arise.
External interference suppression of inductive loads is required.
Connect only the same voltage sources to the relay connections O3 and O4 (e.g. 2 × 240 V AC, same line conductor or 2 × 24 V DC).
WARNING
Non-coded connectors.
The connectors for the operating voltage and of the O3, O4 relays can be mixed up during installation or device replacement.
Electric shock / dangerous voltage possible in the plant.
Check the position and correct connection of the connectors before commissioning.
Electrical safety is ensured.
7.3 Connection technology
ATTENTION
No IP 20 protection without connector.
Cover unused connectors with terminals.
Observe IP 20.
Strip the insulation from the connection cables to 10mm

8.1 Addressing
When mounted and wired the module can be addressed with an addressing cable via the integrated addressing interface.
Assign a free address between 1 and 31, on delivery the address is 0.
9 Operation
Check the safe function of the unit. Display by LEDs:
| LEDs 1 LEDs 2 LEDs 3/4 | LEDs 1 yellow Inputs | switched |
| LED red ERROR Hardware fault / cross fault / short circuit | ||
| LED 2 green Voltage supply OK | ||
| LED 2 red lit AS-i communication error, slave does not participate in the "normal" exchange of data, e.g. slave address 0 | ||
| LED 2 red flashing Peripheral fault, e.g. overload or short circuit of the sensor supply | ||
| LED 3 red Alarm outputs O-1/O-2 (unsafe) (through the host system the alarm output LED can be set as a static or dynamic output) | ||
| LED 4 yellow Relay outputs O-3/O-4 (unsafe) | ||
Overload, cross fault and short circuit of the sensor supply are signalled to the AS-i master (version 2.1) via the "peripheral fault" flag in the status register.

The code words 0000, XX00 and 00XX cause the AS-i safety monitor to bring the installation into the safe state.
For more details on the effect of the data bits on the transmission sequence refer to the configuration software manual (see the chapter "Monitoring devices").
Note: non-safe relay outputs
Do not use the non-safe relay outputs for safety-related functions.
11 Response times
The response time of the safe AS-i module for a safety demand is max. 10 ms. Calculation of the total response time:
For the calculation of the response time of the complete system the response times of the other components also have to be added (mechanical contacts, safety monitor and external relays or contactors possibly connected to the safety monitor output).
If only one single-channel switch is to be connected to the module, it is to be connected to the input S11-S12. The second input S21-S22 must be bridged. This can be done by means of a wire link between the terminals S21 - S22.
Note: The wiring influences the achievable control category.
The requirements for external wiring and the selection of the connected switching contacts refer to the functionality to be accomplished and to the required performance level (EN ISO 13849-1 or IEC 61508).
The performance level is either determined by means of a risk analysis (e.g. to EN ISO 14121) or taken from a C standard. The performance level or SIL of the AS-i safety monitor must at least correspond to the performance level or SIL required by the application.
