Frequently Asked Questions - AC5243 IFM

What is the default address of the AC5243?

At delivery, the address is 0. Use the addressing unit AC1144 to change it.

How to address the module with the AC1144?

Connect the addressing cable E70213 to the mounted and wired module, then address via the implemented interface.

What is the operating pressure range?

The range is 2 to 8 bar. Using pressure outside this range may damage the module.

What do the LEDs on the module mean?

PWR green: AS-i power ok; FAULT red steady: communication error; FAULT red flashing: peripheral fault; AUX green: AUX power ok; LED 1 yellow: logic state of PLC outputs; LED 2 yellow: switched input.

Can lubricated air be used with the AirBox?

Yes, for purity classes 6-3-4. Once used with lubricated air, it must always be used with lubricated air (initial lubrication is no longer effective).

How to connect the sensors?

Connect the sensor connectors to the M12 sockets. Cover unused sockets with protective caps (E73004); tightening torque: 0.6...0.8 Nm.

How to use the manual override?

Press the button to actuate the output (push/release) or press and turn to lock. Electrical control has priority.

What is the protection rating?

IP67 with appropriate seals; if a silencer is used, the protection is IP65.

Can the product be repaired?

No, the product cannot be modified or repaired. In case of defect, contact the manufacturer.

Is the module compatible with an AS-i master version 2.0?

Yes, but parameter P3 must be 1 and output bit D3 must be 0. Use an address between 1A and 31A for extended mode.

Installation

Notes on installation from page 26.

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.

Pneumatics

Circuit diagram pneutatics 2x 3/2-way valve

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 5mg / m^3

1. Maximum water content according to class 3:

Pressure dew point -20°C

1. Maximum total oil content according to class 1: for non-lubricated compressed air 0.01mg / m^3 Maximum total oil content according to class 4: for lubricated compressed air < 5mg / 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 ± 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

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 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 (AC5243) 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.

Orientation of the flat cable on delivery

Carefully place the yellow and optionally the black AS-i flat cable (AC5253) into the profile slot.

Mount the upper part.

With the supplied lower part the flat cable can be aligned in three directions.

For the requested direction place the flat cable guide (1) accordingly.

Settings at the lower part

Select the position 1, 2 or 3 depending on the requested flat cable alignment () .

A = Factory setting

Settings at the upper part

Then set the selected position at the upper part. To do so, turn the arrow to the corresponding number (figure D1 and D2).

Use a tool, e.g. a screwdriver (figure D1) or the yellow / black flat cable guide (figure D2).

Open the unit using a tool as shown (e.g. screwdriver).

Take care in laying the AS-i flat cable, the flat cable should be laid straight for about 15 cm.
