Frequently Asked Questions - AC2505 IFM

How to address the AC2505 module?

You can address the module via the addressing unit AC1144 (by cable or infrared). The address must be between 1 and 31. At delivery, the address is 0. For infrared addressing, first disconnect the master and power the slaves via the AS-i power supply.

What does the red light mean when lit?

The red FAULT (LED2) lit indicates an AS-i communication error: the slave is not participating in normal data exchange (e.g., slave address 0). If it blinks, it signals a peripheral fault, such as an overload or short circuit of the sensor supply.

How to connect sensors to the module?

Connect the sensors to the 4 M12 connectors of the module. Sensor power is supplied via the AS-i network. Do not connect inputs to an external potential. Cover unused connectors with the AC3004 caps to maintain IP67 protection.

What is the maximum number of modules per master?

The maximum number of AC2505 modules that can be connected to an AS-i master is 31.

How to perform infrared addressing?

Use the addressing unit AC1144 with the infrared cable E70211. Before addressing, disable AS-i communication by disconnecting the master. Power the slaves via the AS-i power supply. If using an ifm AS-i SL power supply, communication can be disabled by a connector.

What to do if the red light blinks?

A blinking red FAULT light indicates a peripheral fault, such as an overload or short circuit of the sensor supply. Check the sensor wiring and power supply. The fault is reported to the AS-i master via the internal 'peripheral fault' bit in the status register.

What is the supply voltage of the module?

The module is powered by the AS-i network, typically at 30 V DC. The nominal input voltage is 31.6 V DC (240 mA) for sensor supply, and the output can deliver 30 V DC (200 mA).

How to ensure IP67 protection of the module?

To ensure IP67 protection, unused M12 connectors must be covered with AC3004 protective caps. Also ensure that the wiring base is properly mounted and the seals are in good condition.

Can I use the module with a base without an addressing plug?

Yes, if you use the base AC5000 (without addressing plug), you must first address the module with the AC1144 unit before mounting it on the base. The base AC5010 has an integrated addressing plug for later addressing.

What to do in case of overload or short circuit of the inputs?

In case of overload or short circuit of the sensor supply, the red light blinks and a peripheral fault is reported to the AS-i master. Disconnect the power, correct the fault (e.g., replace the defective sensor), then power on again. The fault is automatically cleared once resolved.

Technical data

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

Electrical connection

Connect the sensors to the M12 sockets. The sensor supply via the AS-i network.

Do not connect the inputs with an external potential.

Cover the sockets not used with the protective caps (AC3004) 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 lower part AC5010 (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 lower part AC5000 (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: input 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 sensor supply
• LED 3: infrared receiver

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