Danger - High voltage
ATTENTION! Before working on the System read the section “Safety Precautions” on
page vii in this Manual.

D.8.3 VCS-voltage control
All Panda generators from Panda 8000 upwards are fitted with the electronic voltage control
"VCS" as standard.
The VCS controls the generator voltage and motor speed. A servo motor on the injection pump
can increase the engine speed by up to 8%.
If the generator is run without load, the voltage should be 240V with a frequency of approx 57,8 to
58,6Hz (48,5 - 49Hz for 230V 50Hz models). The frequency (equates to the speed) can be
increased by up to 8%. This ensures that the engine speed is increased when there is an extra
load. The maximum speed is achieved when 80% load is reached.
All signals pass through the circuit board in the Control box. The signal impulse for the servo
motor is passed to the electric motor by means of the 5 core wire.
The generator maintains its full capability if the VCS has a defect.
In this case the base current must be raised to at least 240V by adjusting the minimum setting on
the speed gauge, in order to ensure that the generator output voltage at 70% nominal load does
not drop below 215V.
