Page 4: Safety
Safety page 1 Safety Definition of Symbols Stop (Stop Danger). This symbol warns of serious danger of severe injury to persons. It must be strictly observed. Attention (Warning). This symbol indicates information the non-observance of which can lead to extensive damage to property. The safety warning must be strictly observed. -
Page 5: Correct Operation
Safety page 2 The ELC causes a leakage current greater than 3.5 mA! Safeguarding by means of leakage current protection type A and type AC according to IEC 60755 is not permitted! The ELC operates in principle as a frequency converter and is equipped with a mains filter whose leakage current could activate fuse protection. -
Page 6: Description Of Functions
Description of functions page 3 Description of functions The electronic ballast ELC is designed to operate medium pressure discharge lamps as described in chapter 6. In contrast to conventional ballasts (inductive lamp ballast or transformer or transformer with transductor), the lamp with an electronic ballast is operated with high frequency (approx. 100 kHz). -
Page 7: Installation
Installation page 4 Installation Mounting of casing The ELC must be installed in a control cabinet with at least IP 54 protection (see EN 60529). Operation without a control cabinet or in a control cabinet with a lower degree of protection is not permitted. The ELC may only be installed vertically (control connections at the bottom, power connection at the top) allowing for at least the minimum spacing as shown. -

Page 17: Explanations Of The Control Functions For Elc
Installation page 14 Explanations of the control functions for ELC 3.4.1 Release relay The release relay indicates the trouble-free operation of the unit. This means that the relay closes when the ELC (see 4.2) is switched on and remains closed during operation providing there is no defect. - Page 18 Installation page 15 Digital: MIN und MAX For certain operation modes the lamp power can be set to Maximum or Minimum independent of the control voltage at SET VALUE. E.g.: • Lamp warm-up: maximum power or • Standby operation: minimum power To this purpose the control inputs MAX and MIN respectively are set to High, whereby the function MAX has the higher priority.

Page 19: Earth Fault Control
Installation page 16 3.4.5 Earth fault control The ELC (electronic ballast) has been fitted with an earth fault control system. The ELC is fitted with an earth fault relay ES for the purpose of indicating an earth fault. During trouble-free operation the relay is closed (provided the ELC is connected to the power supply voltage). -
Page 20: Operation Of Elc
Operation of ELC page 17 Operation of ELC Initial operation The operative parameters of the ELC, such as the scope of the trigger pulse when switching on the lamp, is set by the manufacturer. Alterations to the manufacturer’s settings can only be carried out by the manufacturer. -
Page 21: Dimming Operation
Operation of ELC page 18 Dimming Operation After having reached nominal operation, the desired lamp power can be infinitely adjusted. • Lamp power is adjusted via control voltage (0 – 10 V) at the analogous SET VALUE control input. In this context, 0 V are tantamount to minimum and 10 V to maximum lamp power. The adjustment of lamp power via the analogous SET VALUE control input is only possible if a LOW signal is applied to the digital MIN and MAX control inputs. -
