Frequently Asked Questions - AC2057 IFM

How to address the AC2057 module?

Use the addressing unit. Mount the module on the unit, assign a free address between 1 and 31 (the delivery address is 0). Then mount the module on the wiring base connected to the AS-i network with a tightening torque of 0.8 Nm.

What is the recommended compressed air pressure?

The pressure must be between 3 and 8 bar. Pressure peaks above 8 bar can cause permanent sealing defects and irreversible damage to the AirBox.

How to connect sensors to the module?

Sensors are connected via the M12 pluggable connectors. They can be 2-wire or 3-wire PNP switching sensors according to IEC 947-5-2 or mechanical position switches, wired between pin 1 and pin 2/4.

What do the LEDs on the module mean?

The green LED indicates voltage present via the AS-i network. The yellow LEDs show the status of inputs/outputs.

How to use the manual override of the pneumatic output?

You can operate the pneumatic output (4/2 valve) using the manual control screw. You can choose between push/release or push/turn/lock mode.

What type of compressed air should be used?

Use filtered air (5 µm) and optionally lubricated (ISO-VG10). If the AirBox has been used once with lubricated air, it must always be used with lubricated air.

What EMC precautions should be taken?

Avoid electrostatic discharges by implementing potential equalization and physically separating signal cables, bus cables, equipotential conductors, and power cables. The AirBox is tested according to EN 61000-4-2 with contact discharge ±4kV and air discharge ±8kV.

How to disconnect pneumatic tubes?

To remove the tubes, press the black ring of the fitting and pull the tube at the same time.

What to do if the air pressure exceeds 8 bar?

Strictly avoid pressure peaks above 8 bar, as they can cause permanent sealing defects and irreversible damage to the AirBox. Ensure the compressed air supply is regulated.

Function and features

The AS-i AirBox is a slave in the AS-i system (AS-i profile S 3.F). The electrical inputs are rated for the connection of binary 2-wire or pnp 3-wire sensors to IEC 947-5-2. As an alternative, mechanical position switches can be connected between pin 1 and pin 2/4.

• Integrated sensor supply (a total of 100mA per module)
• Plug-in sensor connection
• AS-i connection via EMS module lower part
• Connection to pneumatic system via push fit tube connector Legris 3000/8mm, outside calibration according to CETOP standards RP 54P
• Operation with compressed air of 3...8bar including any pressure peaks (Pressure peaks >8 bar can cause permanent leaks and irreparable damage of the AirBox).

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.

Materials

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 output (NO/NC selectable) 2 and 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.

Manual override

The pneumatic output (NO/NC selectable) can be activated manually by means of the screw for the manual override (pressing/releasing or pressing/turning/locking).

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: 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.
