Frequently Asked Questions - AC2729 IFM

How to connect the IFM AC2729 electronic card?

Connect the two external mechanical pins I1-2 and I2-2 to one side of the mechanical contacts. The other side of the contacts connects to the black wires I1-1 and I2-1. Insulate any unused stripped wires.

What are the meanings of the LEDs on the card?

The yellow LED 1 indicates that inputs I1 and I2 are switched. The green LED 2 indicates that the power supply is OK (PWR). The red LED 2 indicates an AS-i communication error (FAULT). The external LED output X1-X2 corresponds to output O-1.

How to address the AC2729 card?

Use the addressing unit AC1144 connected via the cable E70032. Assign an available address between 1A/1B and 31A/31B. The default address is 0.

What is the main function of this electronic card?

It detects up to two non-safety switching states from mechanical contacts (normally open or normally closed).

Where to install the IFM AC2729 card?

Mount it in a protected location such as an electrical cabinet or an enclosure with a protection rating of at least IP 54.

What to do if LED 2 is red?

This indicates an AS-i communication error. Check that the slave has a valid address (not 0) and that the communication is correct.

Can the connection wires of the card be extended?

No, the connection wires of the AS-i printed circuit board must not be extended.

How to test proper operation after installation?

Perform a commissioning test to verify proper operation of the device.

What supply voltage is required?

Power is supplied via the AS-i bus, typically at 30 V DC.

USER MANUAL AC2729 IFM

Pure electrical circuit lines without any symbols

Function and features

The AS-i PCB detects up to two unsafe switching states, e.g. 1 or 2-channel mechanical contacts.

Mounting

Install the AS-i PCB in a protected location (e. g. control cabinet, housing). The appropriate housing must have a protection rating of at least IP 54. Carry out a set-up test after installation of the AS-i PCB.

Electrical connection

Connect the AS-i PCB to two mechanical NO or NC contacts. In doing so, the two outer mechanical pins are connected to one side of the contacts (I1-2 / I2-2). The other side of the contacts is connected to the two black wires (I1-1 / I2-1).

Insulate unused open wires. The connection wires of the AS-i PCB must not be extended.

Wiring

A+: AS-i +

A-: AS-i -

11-1/11-2

I2-1/I2-2: switching input mechanical contact I1 / I2

LEDs 1: switching status indication inputs I1, I2

LEDs 2: AS-i, FAULT

X1-X2: external LED output

Data bits

Data bit	D0	D1	D2	D3
In/Out	I-1/O-1	I-2	-	-

Addressing

When mounted and wired the PCB can be addressed via the addressing unit AC1144 using the cable (E70032).

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

If a slave with the extended addressing mode is used in combination with a master of the first generation (version 2.0), the parameter P3 must be 1 and the output bit D3 must be 0*. The output bit D3 and the parameter bit P3 must not be used.

* Default setting

If a slave with the extended addressing mode is used in combination with a master of the first generation (version 2.0), an address between 1A and 31A must be assigned to this slave.

Operation

Check the reliable functioning of the unit. LED display:

• LEDs 1 yellow: inputs switched (I1, I2)
• LED 2 green: voltage supply ok (PWR)
• LED 2 red lights: AS-i communication error, slave
does not participate in the “normal” exchange of data, e.g. slave address 0 (FAULT)

- External LED output (X1-X2): output O-1

(The output LED can be set as a static or dynamic output by the host system)

Limited voltage

The device shall be supplied from an isolating transformer having a secondary Listed fuse rated 5.0 A.
