Frequently Asked Questions - AC2056 IFM

What is the recommended air pressure range for the AirBox AC2056?

The recommended compressed air pressure is 2 to 8 bar. Pressure peaks above 8 bar can cause permanent sealing defects.

How to use the manual control?

The manual control allows activating the pneumatic distributors. Two modes: push/pull or push/turn/lock. Manual control 1 acts on O-3, control 2 on O-4.

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

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

Which EMC standards are met by the AirBox?

The AirBox is tested according to EN 61000-4-2 with levels: contact discharge ±4 kV and air discharge ±8 kV. It is designed for industrial environments.

What do the different LEDs on the AirBox mean?

The green LED indicates power supply via the AS-i network. The yellow LEDs show the status of inputs/outputs. Another green LED indicates external power supply.

Should lubricated air be used?

The air can be lubricated (ISO-VG10) or non-lubricated. However, if the AirBox has been used once with lubricated air, it must always be lubricated afterwards.

How to prevent electrostatic discharges?

To avoid discharges, it is recommended to carry out equipotential bonding, separate signal, bus, and power cables, and keep the AirBox away from electrostatically charged parts.

How to connect the compressed air tubes?

Cut the tubes straight and push them into the connectors until they click. To disconnect, press the black ring and pull the tube.

What materials make up the AirBox?

The seals are made of Viton, the fixing screws and instant connectors are made of stainless steel 303.

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 54P
• Operation with compressed air of 2...8 bar including any pressure peaks (Pressure peaks >8bar can cause permanent leaks and irreparable damage of the AirBox).
• Manual override by pressing/releasing or pressing/turning/locking

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.

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

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: external voltage supply
• 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.
