USER MANUAL AC2501 IFM

Function and features

AS-i profile: S-0.F.E
maximum number of modules per master: 31
- AS-interface version 2.1

Operating and display elements

Mounting

Mount the module onto the wired module lower part of the AS-i network, tightening torque 0.8Nm.

Technical data

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

Electrical connection

Connect the plugs of the actuators to the M12 sockets. The sensors are supplied with voltage via the AS-i network. Do not connect the inputs to an external potential. Cover the sockets not used with the protective caps (AC3004) to guarantee protection rating IP67.

Addressing

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

Do not remove the addressing plug while live.

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).

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.

Function check inputs

In case of a fault the high or low activity (NO or NC principle) of the function check inputs can be set separately for each input via a parameter bit. In case of a fault the red LED of the corresponding input lights and in addition LED 2 (FAULT) flashes.

Switch	Parameter bit	Fault			No error message
		input FKT	FKT LED Fault LED		input FKT	FKT LED	Fault LED
high-active	1 (default)	high	on	on (flashing)	low	off	off
low-active	0	low	on	on (flashing)	high	off	off
FKT function check input I1...I4

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. q. slave address 0
• LED 2 red flashing: peripheral fault, e.g. sensor supply over loaded or shorted or fault on the function check input
• LED 3: infrared receiver
• LED 4 red is lit: fault - output switched (function check input)

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.
