USER MANUAL AC2049 IFM

• 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 54 P

• Operation with compressed air of 3...8 bar including any pressure peaks (Pressure peaks > 8bar can cause permanent leaks and irre- parable damage of the AirBox).

• External voltage supply 24 V DC PELV

• Option: with auxiliary air 90% vacuum 3 ... 8 bar; via tube fitting Legris 3000 / 4 mm 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.

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 auxiliairy air must be rated for at least 3 bar to enable switching of the valve. The auxiliairy 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). 7Electromagnetic 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 pos- sible, 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 carry- ing or discharging electrostatic charges If these discharges are not avoided there is the danger of:

• injury to/incapacitation of operators and maintenance staff

• damage to the AirBox

• damage to the electrical equipment The electrical triggering has priority over the mechanical triggering.

If the voltage is supplied again, the output 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 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.
