- Page 3 ENGLISH INTRODUCTION This Technical Note provides general installation and operating information exclusively concerning the Marelli Motori regulator code specified in the document, mounted on the Marelli Motori synchronous generators specified in the next paragraph “APPLICATION”. Before the generator start and any types of regulation operation, read carefully and completely this Technical Note.
- Page 4 ENGLISH APPLICATION The voltage regulator type “MARK I”, is suitable for Synchronous Generators of MARELLI MOTORI make, MJB series, size range 160-500 frames. This regulator is proper to operate on machines rated from 10 up to 2000 kVA. The regulator is fully insulated in order to maintain high reliability also with severe ambient conditions (high level of humidity, dust, salt atmosphere), and in case of high vibrations level.

- Page 7 ENGLISH The analogue input is usually used for the voltage regulator control by means of the Marelli power factor regulator, for parallel operation with the grid. This input can be also connected to external devices not made by Marelli, for remote control of the generator voltage or the excitation during parallel operations (voltage matching and power factor regulation), as long as those devices were equipped with suitable outputs (insulated...
- Page 8 ENGLISH OVER-EXCITATION LIMITER This function permits to limit the over-excitation due to particular load conditions that could cause the generator damage. As soon as the excitation voltage rises over a certain threshold, set by means of the potentiometer AMP, for a time larger than the limiter time delay, the over-excitation limiter steps-down the excitation voltage to the threshold value.
- Page 9 ENGLISH USE OF POTENTIOMETERS VOLT - potentiometer to change the output voltage of the generator: Normally the internal potentiometer VOLT allows possibility of adjusting the voltage in a wide range (i.e. between 200 and 560 V); to obtain a finer possibility of voltage setting or to adjust the voltage from the control panel, or in order to limit the voltage range, an external potentiometer can be connected to the terminal “P”...
