DIAM Series 53 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. With the word LOOP means the series circuit installed in the field, for the supply of light fixtures. 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.
DIAM Series 53 Reference standards The constant current regulators are manufactured in accordance with the following standard: ● IEC 61820-3-2: Electrical installations for lighting and signalling in airports and heliports - Part 3-2: Requirements for power supplies - Special requirements for series circuits. ● ICAO Doc 9157 -Part 5: Aerodrome Design Manual - Part 5 - Electrical systems. Nb. of steps The constant current regulators can be equipped with a number of steps varying from 1 to 8, each configurable in the range 1.8-6.6 A, to meet different end-user requirements. According to IEC 61822, the nominal output current range is: ● Style 1: from 4.8 to 6.6 A ● Style 2: from 2.8 to 6.6 A The table provides the normalised CCR pre-settings. These settings can be modified in accordance with the requirements of an airport.
DIAM Series 53 Supply voltage The DIAM Series 53 constant current regulators can be supplied with different voltage levels, depending on the network values. The constant current regulators DIAM Series 53 are designed for three-phase power supply (3PH+GND) with rated supply voltage from the following values: 380, 400 o 415V [±10 % (IEC), 50/60 Hz]. Attention: The supply voltage value chosen when ordering cannot be changed. Nominal power The constant current regulators can provide variable output power depending on the chosen configuration. The available sizes are: 2,5 kVA, 5,0 kVA, 7,5 kVA, 10,0 kVA, 15,0 kVA, 20,0 kVA. The constant current regulators are air-cooled. Up to the maximum power of 10.0 kVA, ventilation is natural, while forced ventilation is provided for larger sizes (through internal fans). Attention: The nominal power value chosen when ordering cannot be changed. Wired remote control The constant current regulators can be configured to be controlled and monitored through dry contacts (relay 125 V /2 A or 125 V /2 A for resistive loads) and by an internal or external voltage (from 20 to 60 V , positive or negative) or through multipolar cable (input via cable gland and terminal block attestation or connection through...
DIAM Series 53 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.
DIAM Series 53 2.13 Wiring To wire the DIAM Series 53 system properly, use only cables compliant with the relevant technical specifications (FAA L-824, IEC/EN 60228), specially designed for airport installations and safety-critical systems. The cables necessary for the functioning of the unit are not included in the supply. It is the customer’s responsibility to arrange appropriate certified equipment to connect the units. Before connecting the unit, check that the unit configuration is compatible with the actual system conditions.
DIAM Series 53 INSTALLATION Constant current regulator The DIAM Series 53 constant current regulators, installed to supply the series circuits, are capable of supplying current to the series circuit to provide the necessary brightness to the light fixtures installed on the circuit. The number of selectable brightness levels must be consistent with the intended functionality of the circuit design. The features of series circuit must be compliant with the dispositions of competent bodies and with the regulations in force. The load actually supplied by the series circuit must not exceed the operating limits of the constant current regulator. For the construction of the supply circuits and for the series circuits, refer to the requirements of the relevant Standards. For the conformity of the light fixtures supplied by the constant current regulators through the series circuits, refer to the specific product certifications.
DIAM Series 53 Handling and positioning of the device To position the device correctly, take the following aspects into consideration: ● Access to the unit from the front side must be guaranteed to make operation and maintenance procedures easy. ● The constant current regulators must be arranged side by side. ● Maintain a free space of at least 20 cm at the rear side of the unit to ensure proper ventilation of the device. Before proceeding with the operation, check the conditions of the device: ● check that the mechanical fixing of the components are steady; ● check that the internal connections are properly tightened; ● check that the internal equipotential connections are all well realized. Always use lifting equipment of suitable characteristics: before handling the load, check the weight and dimensions of the load to be lifted, verifying the correct positioning of the centre of gravity.
DIAM Series 53 Preliminary checks Store the device in its original packaging until the time of installation. Check the characteristics of the electrical system into which the device must be integrated before installing the constant current regulator. ● The power supply line must be suitably dimensioned and adequately protected. ● Only use the device in combination with series circuits that comply with the standard FAA AC 150/5340-30 and ICAO Aerodome Design Manual Part 5.
