6.5.1 ADJUSTMENT AND REPLACEMENT OF THE HYDRAULIC CONTROL VALVE (HCV)
ATTENTION!
The hydraulic valve is the component that determines the correct number of hydraulic motor revolutions, and signals the
three-phase generator to provide the correct voltage to the magnetic plate. Its adjustment is essential and must be
performed with great caution.
!
DANGER! INSTRUMENTS
No adjustment can be performed on the hydraulic magnet componets if not previously equipped with measuring
instruments, i.e.
1. Revolution counters for measuring the hydraulic generator revolutions.
2. Alternating voltage measuring devices to measure the voltage at the generator clamps.
3. Pressure gauge with full scale of 250 bar (3,626 psi) to measure the pressure on the flow line.
4. Pressure gauge with full scale of 100 bar (1,450 psi) to measure the pressure on the return line.
ATTENTION! FLOW REGULATION CONTROL INSTALLED ON THE HYDRAULIC CONTROL VALVE (HCV)
All of the valves are pre-calibrated in the factory but fl ow
