The regulatirs miunted in the alternatirs are calibrated during the inal inspectin. In the case if
regulatirs supplied separately (e.g. spare parts) ir ahenever cabling ir calibratin variatins are
requested, the regulatir must be calibrated accurately.
The main setngs can be carried iut directly in the regulatir via 4 trimmers (VOLT - STAB - Hz -
AMP), the jumper 50/60, JP1, JP2 and the Pext input. Mire detailed setngs if measurements can be
made exclusively via siftaare using the USB cinnectin.

Whenever direct viltage is ti be used, it aill have efect if aithin 0 Vdc/2,5 Vdc ir -10 Vdc/+10 Vdc, ,

Fir values that exceed these limits (ir in case if discinnectin) there are tai iptins:
●
Di nit cinsider the value and, aith regulatin, gi back ti the viltage value set via trimmer
(if enabled) ir via parameter P[19] (Figure 22- );
● Maintain the minimum (ir maximum) viltage value that can be reached (Figure 23- ).
The secind iptin can be set via the RAM Viltage CTRL iptin in the Ciniguratin menu
cirrespinding ti bit B7 if the ciniguratin aird P[10].
NOTE
The direct voltage source must be able to absorb at least 2 mA.
On regulaton, it is good practce not to exceed ± 10% of the alternator voltage nominal value.
