i-MARK Installation and Hardware Manual Page 7 of 22 1 Safety Instructions The system described in this manual is for exclusive operation by trained employees. Only qualified personnel that know the potential dangers involved should perform the installation, settings, maintenance and repair of the units used. Operational Safety The correct and safe use of these systems assumes that operating and service personnel follow the safety measures described in the manual alongside the generally acceptable safety procedures. If there is a possibility that safe operation cannot be guaranteed the system must be switched off and secured against accidental use. Then the service unit responsible must be informed. Safety Documents This ILR system was designed, tested and supplied in perfect condition according to document IEC348 Safety Requirements for Electronic Units of Class 1. Condensate / Change of Temperature Moving the systems from a cold to a warm environment could lead to dangerous situations due to condensation. Therefore it must be ensured that the system can adjust itself to the warmer temperature. Do not open the housing There is no need to open the housing in order to set any ILR unit. No unit has any internal setting elements or displays. All settings are performed using software via the Service Interface. Earthing Before establishing any connections the housing of the system must be earthed. Connections / Power Supply The supply circuits must comply with the conditions set out for the SELV circuits (see EN 60950). The signal circuits must comply with the conditions set out for the SELV circuits (see EN 60950). Use screened cables for the power supply. This is the only way to achieve the prescribed EMC. During maintenance damage could occur if printed circuit boards or cables are connected or disconnected whilst the power supply is still on. Therefore only work on the connection and the components when they are not live. Fuses Only experts who are aware of the dangers involved may replace the fuses. It must be ensured that only fuses of the required current rating and the correct type are used for replacement. The use of repaired fuses and/or short-circuiting the fuse holders is prohibited. Spare Parts We recommend that only personnel, original products, spare and replacement parts authorized by IDENTEC SOLUTIONS be used for installation, service and repair. Otherwise IDENTEC SOLUTIONS does not accept any responsibility for materials used, work carried out or possible consequences.

i-MARKInstallation and Hardware Manual Page 8 of 22 Electrostatic Discharge Semi-conductors of the type MOS or CMOS as well as two-pin types and precision resistance are sensitive to ESD. All components, printed circuit boards and auxiliary systems should therefore always be classed as sensitive to electrostatic discharge. Before opening the cover the unit should be placed onto an ESD-protected surface. As with all work on modern electronic modules the use of ESD clamps and ESD mats during work on the unit is recommended. • Sufficiently protect all printed circuit boards that were removed from the unit from damage. • Observe all normal precautions for the use of tools. • Use ESD-protected packaging material. Never use measuring units with low impedance for measuring or testing systems with semi-conductor components. Never use high voltage testing units or dielectric test units to test systems with semi-conductor components. If it is necessary to check the isolating properties of the field wiring, the assemblies (electronic units and sensors) should be disconnected. Earth the test units. IDENTEC SOLUTIONS does not accept returns of products where the regulations concerning the ESD precautions and protective packaging materials were not followed.

i-MARK Installation and Hardware Manual Page 15 of 22 4 Initial Operation 4.1 General Do not open the housing. Opening the housing is not necessary in order to set the i-MARK. The unit has no internal setting elements or displays. All settings are performed using software via the service interface. 4.2 Tools required Hardware PDA running Windows CE with installed Bluetooth interface or, PC running Windows XP with installed Bluetooth interface Software PDA Service Tool “i-MARK-Controller” PC Service Tool “i-MARK Config” 4.3 Configuration In a standard installation only this settings need configuring: • Adjust the inductive loop field • Give every i-MARK a unique ID • Set transmission slots (required only if several loops are in close proximity) 4.3.1 Adjusting the Inductive Loop Field The size of the loop field is adjusted by adjusting the loop current using one of the Service tools. 4.3.2 Adjusting the Inductive Loop Field Every i-MARK in the entire application must have a unique ID in order to avoid confusion. This unique ID value is an integer value.

i-MARKInstallation and Hardware Manual Page 16 of 22 4.3.3 Operation Mode—Continuous/host only Note: The default operation mode is “continuous”, as most i-MARK installations will be autonomous. In the continuous operation mode the i-MARK will transmit the LF telegram based on the slot configuration and synchronized time (refer to the section 4.3.5). In cases where an application may need to have full control over when the i-MARK transmits the LF telegram the i-MARK can be switched into host only mode. The host is then responsible for telling the i-MARK when to transmit a LF telegram. 4.3.4 Operation Mode—Slave/master Note: This default operation mode is master. The recommended configuration is to have a host present on the RS422 bus. This allows for the retrieval of device status information and detection of device failure in real time. In this application, the host will be the master and must send the synchronization messages to the i-MARK and all of the i-MARKs must be configured as slaves. In applications where an i-HUB or host is not required on the bus, but synchronization needs to occur, a single i-MARK on the bus can be configured as a master. An i-MARK which is configured as a master must be the first device in the bus hierarchy. When configured as a master it is only able to communicate with devices which are connected off of its slave port. As such, all other i-MARKs connected must be configured as a slave device. This single master on the bus will be in charge of broadcasting the synchronization messages on the bus. In slave mode the position marker will only transmit the LF telegram based on the synchronization scheme or host request depending in the operating mode. In master mode the device will additionally transmit synchronization telegrams and this independently on the operating mode it is configured in. 4.3.5 Synchronization Mechanism Note: This setting is only of importance if several i-MARKs are in close proximity to each other. The default factory setting is that all time slots are used. The synchronization mechanism goal is to avoid having multiple i-MARKs in overlapped transmit areas transmit at the same time and disturb each other. For this task, all the devices must be synchronized, and follow the synchronization mechanism described below. The modules synchronization is done by having 1 master device (i-HUB or Host application or a i-MARK in master mode) to broadcast on the bus a synchronization telegram on a regular interval. Default configuration is, that a device send in each of the 12 slots. The time is divided in 12 slots of 20 milliseconds each.

i-MARK Installation and Hardware Manual Page 17 of 22 For each i-MARK the application must define in which slot the device will transmit the LF telegram making sure that the devices will not disturb each other. If all i-MARKs are synchronized, the slot sequences on all i-MARKs shall start at the same time. 4.3.6 Slot Configuration Examples Configuration example with two (2) i-MARKS, none of them can transmit at the same time.

4.4 Verifying the Installation After completing the installation the operation must be systematically checked. The installation check can be divided into three sections: • Visual test • Basic operational check • Detailed operational check If the basic check of the operational behavior is to be carried out using a (portable) PC a final check via the intended user control system should also be carried out.

i-MARK Installation and Hardware Manual Page 19 of 22 5 Troubleshooting 5.1 General This chapter covers how faults can be recognized and rectified. There are potentially four main problem sources: • The user control system, including task requirements, communication cables, peripheral units with possible object recognition switches. • The ILR system including peripheral units and their cables, also potential object recognition switches. • The environment including large objects between antenna and tag, electrical disturbance sources, human intervention, etc. • The quality of the technical design, including alignment between antenna, ratio of task requirements/available communication time etc. The information about system performance is contained in the relevant datasheets. When planning the total system do not forget these problem sources and “Fault finding procedures on system level” should possibly be included in the host system. How this could look in detail depends on the relevant system concept and very likely varies from one system to another. 5.2 Status Display (LEDs) LOOP This LED lights green during sending a LF telegram (about 20 ms). In the case of a loop error (loop broken or the set point of the loop current couldn’t be reached) the LED lights red when sending a LF telegram. RUN This LED blinks green, indicating the system is running normal. BUS Lights green during receive and orange during response – also for Bluetooth. ERR Blinking: system error on start-up, firmware execution failed. 5.3 Loop Error There are three types of possible errors. Every of the following errors will switch the LOOP LED to red. Also the marker will try to continue sending. Loop broken Loop current is too low or near zero Loop current out of range When setting the loop current (power) the marker tries to control the output signal in a way, that the preset current is measured during LF transmission. This adjustment is only done once, if the loop current is changed by the user. During normal operation the loop current is observed every telegram. If then the loop current is ±20 % out of range the error condition will set. Loop shorten

i-MARKInstallation and Hardware Manual Page 20 of 22 6 Maintenance 6.1 General In principle, the ILR system is maintenance-free. When correctly installed it operates for many years without any problems. 6.2 Tag Battery Life The selected batteries are long life lithium batteries whose service life depends on the extent of the data communication and the ambient temperature of the application area. If this temperature is extreme the service life of the battery is slightly reduced. The long-term load due to high temperatures should therefore be avoided. However, the service life of the batteries in most industrial environments should be at least 6 years depending on the type of the tag and the operating conditions mentioned on the data sheets of the tag. 6.3 Precautionary Maintenance Regular checking of all ports and cables belonging to the system is recommended. Unstable connections could lead to damage and malfunctions of the system and therefore should be repaired as soon as possible. A Brief Checklist • Are all casing intact? • Are all cables intact? • Are all connectors intact? • Are all connectors securely fastened? • Are all screws still tight? • Is there suddenly a malfunction at a specific unit? 6.4 Exchanging a marker within the daisy chain • Stop the application program on the host • Exchange the reader • Restart the application program on the host. If the application on the host checks on startup the marker serial numbers as recommended, it will detect the changed configuration and require either manual intervention or automatically configure the new device. • Firmware Update The firmware is stored in a FLASH memory an can be updated if needed.

i-MARK Installation and Hardware Manual Page 21 of 22 6.5 Spare Parts 6.5.1 Recommended spare parts stock In order to keep the down time of the system during malfunctions as short as possible it is recommended to have certain spare parts in stock. At least one central unit, one antenna and one antenna cable should be available. With larger systems with more than approx. 15 i-MARKs the doubling of the recommended stock quantity should be considered. Furthermore, it is recommended to have several spare tags in stock, corresponding to approx. 0.5 – 1 % of the total number of tags. 6.5.2 Preparing the spare parts In general all spare parts can be used immediately after delivery from IDENTEC SOLUTIONS. However, for the compact communicator there are various settings of the communication parameters. In order to keep the down times short it is recommended to set these parameters before the component is entered into the spare part stock system. In most cases all units within an identification system are used in the same way so that only one setting is required. 6.5.3 Examination and repair of exchanged parts The data tags and compact communicators are complex electronic power units on which the customer can carry out only very limited repairs. Normally the repairs are carried out at IDENTEC SOLUTIONS or possibly at a distributor. Before a part is sent in for repair a short examination should be carried out. 6.6 Returns Parts or main components returned for repair or exchange must be handled with great care. PC cards must be returned in the appropriate ESD-protecting packaging material. All returns should include a completed returns form (see appendix) and be sent to the local distributor or to: IDENTEC SOLUTIONS AG Service Department Millenium Park 2 6890 Lustenau AUSTRIA / AUTRICHE
