Frequently Asked Questions - AC2058 IFM

How to assign an address to the AirBox AC2058?

Mount the module on the addressing unit. Assign a free address between 1 and 31 (at 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 required power supply?

The AirBox is powered via the AS-i network (24 V DC PELV). It integrates a sensor supply of 100 mA total. An external 24 V DC PELV supply is also required for the outputs.

How to connect the sensors?

The 2-wire or 3-wire PNP discrete sensors are connected to the M12 plug-in connectors. The pin assignment is indicated in the manual: pin 1 for L+, pin 3 for L-, pin 4 for data input I, pin 2 for data input II, pin 5 not used.

How to disconnect the pneumatic tubes?

To remove a tube, press the black ring on the Legris fitting and pull the tube at the same time. Cut the tube straight before insertion.

Can the pneumatic output be actuated manually?

Yes, with the manual control screw. You can push/release or push/turn/lock to actuate the 4/2 valve. Electrical control remains priority.

What compressed air pressure is recommended?

The AirBox operates with compressed air from 3 to 8 bar. Pressure peaks above 8 bar can cause irreversible damage. Use filtered air (5 μm) and lubricated (ISO-VG10) or non-lubricated.

What to do in case of electrostatic discharge?

The AirBox is tested according to EN 61000-4-2 (contact discharge ±4 kV, air ±8 kV). To avoid stronger discharges, ensure potential compensation, separate signal cables from power cables, and keep the AirBox away from charged parts.

How to interpret the AirBox LEDs?

The LEDs indicate: one green LED for AS-i power, two yellow LEDs for input/output status, and one green LED for external 24 V power.

What to do if the external 24 V supply is cut (emergency stop)?

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

USER MANUAL AC2058 IFM

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 100 mA 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 / 8 mm, outside calibration according to CETOP standards RP 54 P
• Operation with compressed air of 3...8 bar including any pressure peaks (Pressure peaks >8 bar can cause permanent leaks and irreparable damage of the AirBox).
  • External voltage supply 24 V 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 0.8 Nm.

In a dusty environment the AirBox should be mounted with the filter facing downwards.

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 ± 4 kV
• air discharge ±8 kV

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.

If the external 24 V 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.

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.
