  • Page 6: Package Content

    DIAM3200 Package content The CCRs DIAM3200 of OCEM Airfield Technology are optimized static power supplies, controlled by IGBTs (insulated gate bipolar transistors), designed to maintain a constant output current, independent of load or power supply fluctuations. The output current remains constant with an accuracy of 100 mA for mains voltage fluctuations ± 10% and with all loads between 0 and 100% and up to 30% of transformers with open secondary. Thanks to its unique power architecture, the CCRs DIAM3200 of OCEM Airfield Technology introduce no distortion or degradation of the power factor, which remains that of the load. The harmonic content reflected on the supply network is therefore particularly low, over the entire output current range and for any load. No adaptation to the load via sockets is necessary. The digital processing capability of the DSP processor allows it to be adapted to any type of load: LED fixtures, halogen fixtures, electronic converters or combined systems. The CCRs DIAM3200 of OCEM Airfield Technology perform an automatic calibration that avoids any analogue adjustment during maintenance. A simple and intuitive HMI user interface allows clear display of alarm indications, of the CCR status and of all relevant parameters. These devices are specially designed for supplying airport visual aids, in compliance with all international standards. The device is designed in compliance with: ● ICAO Airport Design Manual, Part 5; ● IEC 61822 (CCR), 61821 (Maintenance). Immediately check for visible damages of the device and of the containing parts. Carefully unpack the device and check for visible damages.

  • Page 11: Fixture Description General Characteristics

    DIAM3200 FIXTURE DESCRIPTION General characteristics The DIAM3200 constant current regulators are designed for the purpose of powering series circuits for luminous fixtures of airport areas: runways, taxiways and aircraft aprons. The DIAM3200 constant current regulators (URCC) are optimized static power supplies, whose control is ensured by insulated gate bipolar transistors (IGBT), capable of maintaining constant the output steps independently from the load fluctuations and the supply voltage. The DIAM3200 constant current regulators are stackable (max. 3 units) to optimize the space they occupy on the ground. The DIAM3200 constant current regulators are compliant with the rules: IEC 61822, Edition 2.0 AENA DIN/DNYM/PPT/002-05/13 The DIAM3200 constant current regulators described in this manual have been designed to be installed on the levelled floor with adequate flatness and strength characteristics. The normal installation condition is a fixed, stable and non-slip floor, free of protuberances, hollows or inclined planes, designed and constructed with characteristics suitable to the actual operating conditions.

  • Page 12: Operating Principle

    DIAM3200 Operating principle The control and management system of the device is scheduled to manage the operation of the constant current regulator automatically. The unit also provides the possibility of advanced functions, which can be activated by the user if required (Wig-Wag mode and 4-20 mA mode). When a brightness level is selected, the system activates the main contactor and adjusts the bipolar transistors to supply the output series circuit with a current value in accordance with the set value. The device continuously measures the loop current (via a Hall effect sensor), which is compared with the set value. The detected rejection is used to correct the operating parameters via a digital regulator. The dischargers on the output line of the device (OLA) protect the device from any overvoltages in the circuit. The burnt lamps detector (LFD) allows the detection of the presence of burnt lamps on the series circuit. If used, the LFD function must be properly configured and calibrated on the field. Optional devices perform control and monitoring of the operating parameters, disconnection manoeuvres of the output circuit to the load, and input overvoltage protection, simplifying the operation and functioning of the device: ● An insulation monitoring system (EFD) allows continuous analysis of the resistance value between the series circuit and earth, signalling the exceeding of the pre-alarm and alarm thresholds. ● An output disconnection device (CUT-OUT) simplifies the maintenance on the HV side: units equipped with the disconnection device can be serviced without the need to disconnect the series circuit terminals and the earth connection. ● Input discharger (ILA) system to protect against overvoltages on the unit's supply line of the device. In addition to local control, the constant current regulator can also be controlled remotely through suitable connection interfaces. Supervision of the constant current regulator management system can be done through the integrated display and keypad, or through the Alize software interface (using an external PC connected via USB cable to the controller). By means of the optional integrated output circuit selector (ICS), it is possible to select which portion of the series circuit to power, in addition to the set current level.

  • Page 16: Behaviour In Case Of Fault

    DIAM3200 2.12 Behaviour in case of fault If the unit detects a fault or an error, the control system applies corrections and informs the operator through a message on the display. The possible types of warning are: ● WARNING: the constant current regulator continues normal operation but alerts the operator that a problem is present (this is the case with EFD or LFD fault). ● ALARM: the constant current regulator is unable to continue normal operation and interrupts the current supply due to an internal fault (e.g. alarm of one of the overcurrent threshold levels) or an external fault (e.g. open circuit). When a fault occurs, prompt action must be taken to identify the cause of the fault and eliminate the problem. The system can only be reset by means of a manual reset (STOP key). The unit preserves the memory of messages detected during operation even in the event of the supply voltage.
