Frequently Asked Questions - AC2043 IFM

How to address the AC2043 AirBox?

Use an addressing unit to assign a free address between 1 and 31. At delivery, the address is 0. Mount the module on the unit, assign the address, then mount it on the AS-i wiring module.

What types of sensors can I connect?

You can connect two double sensors via the pluggable M12 sockets (pin assignment specified in the manual). The sensor power supply is integrated (100 mA total per module).

How to connect compressed air?

Use 8 mm tubes (Legris 3000 system). Cut the tube straight, push it into the fitting until it clicks. Observe the pressures: 2 to 8 bar.

What to do if an LED does not light up?

Check the external 24 V DC power supply and the AS-i network voltage. The green LED indicates AS-i power, the yellow LEDs indicate inputs/outputs, and a second green LED indicates external power.

How to use the manual control?

Press manual control 1 to activate output O-3, and control 2 for O-4. The electrical control takes priority.

What EMC precautions should be taken?

The AirBox is tested according to EN 61000-4-2 (contact discharge ±4 kV, air ±8 kV). To avoid stronger discharges, follow the installation instructions: equipotential bonding, separation of signal, bus and power cables.

Can I use non-lubricated air?

Yes, but if the AirBox has been used with lubricated air once, it must then always be supplied with lubricated air (the initial lubrication is no longer effective after using lubricated air).

How to disconnect the tubes?

Press the black ring of the fitting and pull the tube simultaneously.

What happens in case of a 24 V external power supply failure?

The AirBox outputs must be deactivated by software in the controller. When power is restored, they can be reactivated if necessary.

Where to find additional technical information?

On the ifm-electronic.com website, enter the article number of your AirBox in the data sheet for notes on compressed air and EMC/ESD.

USER MANUAL AC2043 IFM

Function and features

The AS-i AirBox is a slave in the AS-i system (AS-i profile S 7.F). It is the connection between the two dual sensors, the two pneumatic outputs and the AS-i master.

• Integrated sensor supply (a total of 100mA per module)
• Plug-in sensor connection
• AS-i connection via EEMS module lower part
• Connection to pneumatic system via push fit tube connector Legris 3000 / 8mm, outside calibration according to CETOP standards RP 54 P
• Operation with compressed air of 2...8bar including any pressure peaks (Pressure peaks >8 bar can cause permanent leaks and irreparable damage of the AirBox).
• External voltage supply 24V DC PELV

Mounting

Address assignment by means of the addressing unit.

Fix the module onto the addressing unit. Assign a free address between 1 and 31; the factory preset is 0.

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

Compressed air

Adhere to the safety regulations and provisions for the installation of pneumatic systems. Switch off pressure.

Connect the compressed air supply 1 (P), the pneumatic outputs (O-3, O-4) and, if necessary, the exhaust 3 (R) to the pneumatic system. Cut the connection tube straight and push it into the tube fitting until you can feel the tube latch.

Removal of the tubes

To remove the tubes, push the black ring and pull out the tube at the same time.

The manual overrides can operate the pneumatic outputs. Connect the compressed air supply to the AS-i AirBox. If you then push the manual override 1, the output O-3 is triggered. If you push the manual override 2, the output O-4 is triggered.

Electromagnetic compatibility (EMC):

The AirBox is rated for operation in industrial environments. The test of the electrostatic discharge was carried out in accordance with EN 61000-4-2 with the following test levels:

• Contact discharge ± 4kV
• air discharge ± 8kV

Special applications such as the conveying and distribution of bulk material can generate higher electrostatic charges.

To avoid electrostatic discharge the following remedial actions are possible, among others:

• Equalisation of potential according to the installation instructions

• Separate laying of

• signal and bus cables

• equipotential bonding conductors

• power cables

• physical separation of the AirBox and all cables from all parts carrying or discharging electrostatic charges

If these discharges are not avoided there is the danger of:
- injury to/incapacitation of operators and maintenance staff
- spark formation
- damage to the AirBox
- damage to the electrical equipment

The electrical triggering has priority over the mechanical triggering.

Operation

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

• LED green: supply voltage via the AS-i system
• LEDs yellow: function display
• LED green: external voltage supply

For trouble-free operation sufficiently treated air must be used (filtered air 5 m , lubricated (ISO-VG10)1) or not lubricated). Once the AirBox has been operated with lubricated air, it always has to be operated with lubricated air as the oil removes the initial lubrication.

1) You can find further notes on compressed air and EMC/ESD for the AirBox at www.ifm-electronic.com. Enter the article number of your AirBox on the start page under "Data sheet direct". You receive the additional product information by clicking on "Additional data".

If the external 24V voltage is switched off (e.g. by emergency off), the outputs of the AirBox in the controller have to be reset by software.

If the voltage is supplied again, the outputs can be set again if necessary.
