Frequently Asked Questions - AC5253 IFM

How to address the AC5253 module?

Use the AC1144 addressing unit with the E70213 cable. The default address is 0. In extended mode, when coupled with a V2.0 master, the address must be between 1A and 31A, parameter P3 set to 1, and bit D3 set to 0.

What is the operating pressure range?

The operating pressure range is 3 to 8 bar. Use outside this range may cause sealing defects or irreversible damage.

What quality of compressed air is required?

For non-lubricated air: purity class 6-3-1 (particles <5 µm, dew point -20°C, oil <0.01 mg/m³). For lubricated air: class 6-3-4 (oil <5 mg/m³). Lubricated air requires continuous lubrication.

What do the LEDs on the device mean?

Green PWR LED: AS-i power OK. Red FAULT LED steady: communication error (e.g., address 0). FAULT blinking: peripheral fault (e.g., short circuit). Green AUX LED: AUX power OK (AC5253). Yellow input LED: input switched. Yellow output LED: logic state from PLC, not necessarily the pneumatic state.

How to use the manual override?

The manual override allows actuating the pneumatic output by push/release or push/turn/lock. The electrical control takes priority.

What are the mounting instructions?

Mount the base by orienting the flat cable in one of the 3 directions (1, 2 or 3). Set the position on the upper part by turning the corresponding arrow. Open the device with a screwdriver. Leave a straight cable length of at least 15 cm.

How to connect the electrical and pneumatic cables?

Connect the sensors to the M12 connectors (torque 0.6-0.8 Nm). Cover unused connectors with protective caps. For pneumatics, insert the tubes into the dedicated fittings (compressed air, cylinders, exhausts). Use a sealing ring if the module is at the end of the cable assembly.

What to do in case of defect or failure?

No repair is possible. Contact the manufacturer (IFM) for replacement. Do not modify the product.

How to avoid electrostatic discharges?

Follow the installation instructions: potential equalization, separation of signal cables, bus, equipotential bonding, and power supply. Avoid any proximity to electrostatically charged parts.

Is the module compatible with a first generation AS-i master (V2.0)?

Yes, with extended addressing mode. In this case, parameter P3 must be set to 1 and output bit D3 set to 0. The address must be between 1A and 31A.

Functions and features

• maximum number of modules per master: 62
• AS-interface version 3.0, downward compatible
- connection to the pneumatic system via tube fitting, outside calibration according to CETOP standards RP 54 P
- operating pressure range 3...8 bar

Operation outside the indicated operating pressure range or use of incorrectly processed compressd air can cause permanent leaks and irreparable damage to the pneumatic components and may lead to malfunctioning.

Installation

Notes on installation from page 20.

Addressing

At the factory the address is set to 0.

Addressing with the AC1144 addressing unit

When mounted and wired the module can be addressed with the addressing cable (E70213) via the implemented addressing interface.

If a slave with the extended addressing mode is used in combination with a master of the first generation (version 2.0), the parameter P3 must be 1 and the output bit D3 must be 0*. The output bit D3 and the parameter bit P3 must not be used. * Default setting

If a slave with the extended addressing mode is used in combination with a master of the first generation (version 2.0), an address between 1A and 31A must be assigned to this slave.

Electrical connection

Connect the plugs of the sensors to the M12 sockets.

Cover the unused sockets with protective caps (E73004)*, the addressing socket with the supplied protective cap. Tightening torque 0.6...0.8 Nm.

To guarantee protection rating IP 67 you also have to

• use the flat cable end seal (E70413)* if the module is at the end of the cable line
  • discharge exhaust air via the tube connection

* to be ordered separately

If the AirBox is operated with silencer, the protection rating is IP65.

Compressed air

Adhere to the safety regulations and provisions for the installation of pneumatic systems. Switch off pressure. Connect the compressed air supply 1, the operating connections 2 and 4 and if necessary the exhaust 3 and 5 to the pneumatic system. Cut the connection tube straight and push it into the tube fitting.

Removal of the tubes

To remove the tube push the grey clamping ring and pull out the tube at the same time.

Manual override

The pneumatic output can be activated manually using the manual override (pressing/releasing or pressing/turning/locking).

For trouble-free operation sufficiently treated air must be used.

The electrical triggering has priority over the mechanical triggering.

Specification of the compressed air purity

According to ISO 8573-1: 2001 the air purity is divided into three classes:

1. The purity class of the solid particle content
2. The purity class for the humidity content
3. The purity class for the total oil content

The AirBoxes are suitable for non-lubricated compressed air of the purity classes 6-3-1 and for lubricated compressed air of the purity classes 6-3-4.

Meaning:

1. Solid particle contamination according to class 6: Max. particle size 5 m, max. particle density 5 mg / m ^3
2. Maximum water content according to class 3: Pressure dew point -20°C
3. Maximum total oil content according to class 1: for non-lubricated compressed air 0.01 mg / m ^3 Maximum total oil content according to class 4: for lubricated compressed air < 5 mg / m ^3 , this corresponds to approx. 1 oil drop / 4000 litres of air

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.

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

Operation

Avoid build-up of dirt and dust on the upper and lower parts so that the locking mechanism is not affected.

Check the reliable functioning of the unit. Display by LEDs:

LED PWR LED FAULT LED 1 LED 2 LED AUX

• LED 2 yellow: input switched
• LED PWR green: AS-i voltage supply ok
- LED FAULT red lights: AS-i communication error, slave does not participate in the „normal“ exchange of data, e.g. slave address 0
- LED FAULT red flashing: peripheral fault, e.g. overload or short circuit of the sensor supply

Important notes on LED AUX and LED 1

- LED AUX green: AUX voltage supply OK (AC5253) Application of the AUX voltage is only indicated if the AS-i voltage is also available.

- LED 1 yellow: Only indicates the logic state of the PLC outputs. The pneumatic output status does not necessarily correspond to the indicated status of LED 1. The pneumatic output status is not indicated on the unit.

Maintenance / repair

The unit must not be modified nor can it be repaired. In case of a fault please contact the manufacturer.
