Frequently Asked Questions - AC2046 IFM

How to address the AC2046 AirBox?

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

What is the required compressed air pressure?

The AirBox operates with compressed air from 3 to 8 bar. Pressure peaks above 8 bar can cause permanent sealing defects.

How to connect the sensors?

2-wire or 3-wire PNP sensors (according to IEC 947-5-2) are connected to M12 sockets. The pin assignment is indicated in the manual (pin 1 for L+, pin 3 for L-, etc.).

How to use the manual control?

The manual control screw allows manual actuation of the pneumatic output. You can push/release or push/turn/lock. The electrical control has priority.

When to use auxiliary air?

Auxiliary air is necessary if the operating pressure is below 3 bar, if vacuum is to be used, or to compensate for a pressure drop due to a large number of actuators connected in parallel.

What do the LEDs on the AirBox mean?

The green 'PWR' LED indicates the presence of AS-i voltage. The yellow LEDs I-1 and I-2 show the input status, and the LED O-3 shows the pneumatic output status.

How to maintain the AirBox?

Use filtered compressed air (5 µm) and lubricated (ISO-VG10) or non-lubricated. If the device has been used with lubricated air, it must always be lubricated afterwards.

What EMC precautions to take?

Respect the test levels: contact discharge ±4 kV, air discharge ±8 kV. To avoid stronger discharges, ensure potential compensation, separate signal and power cables, and isolate the AirBox from any electrostatic source.

How to disconnect the compressed air hoses?

Press the black ring of the Legris 3000 fitting while pulling the hose.

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 >8bar can cause permanent leaks and irreparable damage of the AirBox).
• Option: with auxiliary air 90% vacuum, via tube fitting Legris 3000/4mm

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 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.

Auxiliairy air

Auxiliairy air is needed

• if pressures below 3bar are to be used
• if a vacuum is to be used
• for parallel wiring of valves if a considerable pressure drop is to be expected (with a high simultaneity factor)

The auxiliary air must be rated for at least 3 bar to enable switching of the valve.

The auxiliary air fitting is integrated in the module and is activated by connecting the 4mm tube for compressed air. If no tube is connected, this pneumatic input is closed (IP67).

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 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.
