Frequently Asked Questions - AC2041 IFM

How to assign an AS-i address to the AC2041?

Place the module on the addressing unit and select a free address between 1 and 31 (factory address 0). Then mount the module on the wiring module connected to the AS-i network with a tightening torque of 0.8 Nm.

What power supply is required for the AirBox AC2041?

The module requires an external 24 V DC PELV power supply as well as power via the AS-i bus. An integrated sensor power supply provides 100 mA total per module.

How to connect the compressed air hoses?

Cut the hoses straight and push them into the Legris 3000 connectors (8 mm) until they click. The supply is on (P), the valve outputs on (O-3, O-4) and the exhaust on (R). Observe a pressure of 2 to 8 bar.

What to do if an LED does not light up?

Check that the AS-i power (green LED) and the external power (other green LED) are present. The yellow LEDs indicate the input/output status. If an LED is off, check the wiring and the EEMS wiring module.

How to use the manual control of the valves?

Press manual control 1 to switch output O-3, and manual control 2 for O-4. The electrical command takes priority over the manual command.

What are the precautions against electrostatic discharge (ESD)?

Perform potential equalization according to the installation instructions, separate signal/bus cables from power cables, and keep the AirBox away from any electrostatically charged source. Discharges can damage the module.

Can non-lubricated air be used?

Yes, but if the AirBox has already been used with lubricated air, it must then always be lubricated (ISO-VG10 oil). The air must be filtered to 5 µm.

How to disconnect the air hoses?

Press the black ring of the connector while pulling the hose. Do not force it, the ring must be pressed to release the hose.

What is the weight and dimensions of the AC2041?

This information is not specified in the manual. Please refer to the technical datasheet on the IFM website (www.ifm-electronic.com) by entering the article number AC2041.

What to do in case of a 24 V external power failure?

The AirBox outputs must be deactivated via software in the controller. When power returns, they can be reactivated if necessary.

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 >8bar 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 5μm, 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.
