Frequently Asked Questions - AC2508 IFM

How to address the AC2508 module?

You can use the AC1144 addressing unit with cable E70213 (for base with plug) or infrared addressing via cable E70211. The address must be between 1 and 31; at delivery it is 0.

What to do if the red FAULT LED is on?

A red LED on indicates an AS-i communication error or a slave address of 0. Check the AS-i wiring and the module address.

How to install the AC2508 module?

Mount the module on the AS-i wiring base. Tighten the screws to 0.8 Nm. Then connect the actuator connectors to the M12 sockets.

What is the IP protection of the module?

The module offers IP67 protection provided that unused M12 sockets are sealed with caps (ref. AC73004).

Can I address the module while powered?

No, especially do not remove the addressing plug while powered. For infrared addressing, AS-i communication must be deactivated (disconnect the master or use an ifm power supply with shutdown function).

What does the flashing red LED mean?

A flashing red LED indicates a peripheral fault, such as an overload or short circuit on an output. The AS-i master receives this information via the internal 'peripheral fault' bit.

How many AC2508 modules can be connected to an AS-i master?

Each AS-i master can manage up to 31 slave modules, including the AC2508.

Is the AC2508 module compatible with AS-i bus version 2.1?

Yes, it is specified for AS-interface version 2.1 and supports profile S-8.0.E.

Where to find the detailed technical data sheet of the AC2508?

The technical data sheet is available for download at ifm-electronic.com. Enter AC2508 in the search.

Which accessories are recommended for addressing?

The AC1144 addressing unit, the addressing cable E70213 (for base with plug), and the infrared addressing cable E70211 are necessary depending on the chosen method.

Technical data

You can download the data sheet from the Internet address www.ifm-electronic.com if required.

Electrical connection

Connect the plugs of the actuators to the M12 sockets. Cover the sockets not used with the protective caps (AC73004) to guarantee protection rating IP67.

Addressing

Assign a free address between 1 and 31. At the factory the address is set to 0.

Addressing with the addressing unit AC1144

If the mounted and wired module is used with the FC-E lower part AC5011 (with addressing socket), it can be addressed via the addressing cable (E70213).

Do not remove the addressing plug while live.

If it is used with the FC-E lower part AC5003 (without addressing socket) the module must first be addressed via the addressing unit AC1144 and then mounted onto the lower part.

Infrared addressing

The AS-i module also offers the option of infrared addressing with the addressing unit AC1144.

The AS-i communication (yellow cable) must be switched off during the infrared addressing. To do so, disconnect the master.

Supply the slaves with voltage via the AS-i power supply. Addressing is carried out via the IR addressing cable E70211.

When the ifm AS-i power supplies SL are used the communication can be deactivated via a plug on the power supply.

Operation

Check the safe functioning of the unit. Display by LEDs:

• LED 1 yellow: output switched
• LED green: voltage supply o.k.
- LED 2 red is lit: AS-i communication error, slave does not participate in the “normal” data exchange, e. g. slave address 0
- LED 2 red flashing: peripheral fault, e.g. overload or short circuit of the output

Overload and short circuit of the output are signalled to the AS-i master (version 2.1) via the "peripheral fault" flag in the status register.
