AC2044 - Interface IFM - Free user manual and instructions

USER MANUAL AC2044 IFM

• 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 2...8bar including any pressure peaks (Pressure peaks >8bar can cause permanent leaks and irrepa- rable damage of the AirBox). 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 net- work, tightening torque 0.8Nm. In a dusty environment the AirBox should be mounted with the filter facing downwards. PAGE 5 I-1/2 I-3/4 I-1 I-3 I-4, O-4 I-2, AS-i PWR, O-3 exhaust 3 [R] compressed air 1 [R] pneumatic outputs O-3/O-4 manual override 1 for O-3 manual override 2 for O-4 flat cable yellowCompressed 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 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 PAGE 6If 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. 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.

Depending on the unit version the exhaust air is filtered with a sinter- ed exhaust or leaves via a common exhaust. PAGE 7
