5.12.3 Electronic voltage control VCS (not existent at ND models)<br />
Installation Instructions<br />
All Panda generators from Panda 6000 upwards are fitted with the electronic voltage control "VCS" as standard.<br />
The VCS controls the generator voltageand motor speed. An actuator on the injection pump can increase the engine<br />
speed compared to the idle speed.<br />
If the generator runs without load, the frequency should be approx. 48,5 - 49 Hz (50 Hz System) or 58,5 - 59 Hz (60<br />
Hz System). The frequency (equates to the speed) can be increased by up to 8%. This ensures that the engine<br />
speed is increased when there is an extra load. The maximum speed is achieved when 80% load is reached.<br />
The speed gauge is governed and limited by an adjusting screw, above and below. Adjustment of this screw may not<br />
occur without the expressive approval of the manufacturer.<br />
All signals pass through the circuit board in the AC-Control box. The signal impulse for the actuator is passed to the<br />
electric motor by means of the 5-core wire.<br />
The generator maintains its full capability if the VCS has a defect. In this case the base current must be raised by<br />
adjusting the minimum setting on the speed gauge to 5 % of the nominal load (for example 240V at a 230V system),<br />
in order to ensure that the generator output voltage at 70 % nominal load does not drop (for example 215V at a 230V<br />
system).<br />

An alternative for generators without AC-Control box is the<br />
Mini-VCS.<br />
The Mini-VCS and the capacitors may be mounted at the generator.<br />
