Page 4: General Information
5 days from receipt to our retailer or, in the event of direct purchase, to Pedrollo Customer Service. • The indications and instructions in this manual refer to standard use of the product; for situations, functions or particular applications not described below, contact the retailer. -
Page 5: Warnings
• Only qualified personnel capable of making electrical connections in accordance with national regulations may carry out installation and maintenance. • The VSP must only be used for the purpose and operation for which it was designed. Any other application and use should be considered misuse and hazardous. -
Page 6: Product Description
PRODUCT DESCRIPTION VSP is a speed regulator with the following characteristics. • It receives mono-phase or three-phase alternating voltage. • It supplies alternating three-phase output voltage. • Check motor on 3 phases. • Variable speed adjustment (inverter) • Keeps system pressure constant (curves with variable rotations). -
Page 7: Use Limitations
AUTO-LIMITATION FOR OVERLOAD If the current detected by the inverter or the temperature of the inverter components exceeds the safety limits, VSP proceeds with a progressive reduction in operating frequency until the values exceeding the limits have returned within them. -

Page 25: Troubleshooting
ALARM DESCRIPTION If the VSP is found in any work mode and the voltage of the “Bus DC Link” is too low, the VSP ERROR PFC.VDC.LOW goes in alarm mode. In this condition the pump is blocked, at the same time the ALARM OUTPUT relay activates, which can generate an external acoustic and visual signal. - Page 26 • Check the input voltage for some reason has not increased in value, or the to protection due to input overvoltage VSP is not connected to an inadequate power system (400V instead of 230V). alarm “MAX.VOLTAGE”. • Check the condition on the power cables.
