1. VASCO Introduction
VASCO is a variable frequency drive designed to control and protect pumping systems by varying the output frequency to the
pump.
VASCO can be applied to both new and existing pumping systems, and provides:
energy and cost savings
simplified installation and an overall lower pumping system cost
longer life of the pumping system and relevant components
improved reliability
VASCO, when connected to any pump, manages the system operation to maintain a certain constant physical quantity
(pressure, differential pressure, flow, temperature, etc.) regardless of the conditions of use. The pump is operated only when
needed thus avoiding unnecessary energy consumption.
VASCO at the same time is able to:
protect the motor from overload and dry running
implement soft start and soft stop to increase the system life and reduce current peaks
provide an indication of current consumption, voltage, and power
maintain a record of run time and display any errors and/or failures reported by the system
control up to two additional pumps at a constant speed (Direct On Line)
connect to other VASCO units for combined operation
Through the use of inductive filters (optional) VASCO eliminates dangerous surges that are induced in long cables, making
VASCO suitable for control of submersible pumps.
2. Safety Instructions
The manufacturer strongly suggests carefully reading this operation manual before using and installing its products
Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel.
Failure to observe and follow the instructions in this manual may result in dangerous and potentially lethal electric shock.
Pay attention to all standard safety and accident prevention regulations
The device must be connected to main power supply via a switch to ensure the
complete disconnection from the network before any operation on the VASCO
itself (including visual inspection) and/or on the connected load.
Disconnect VASCO from the main power supply before commencing any work.
Do not remove, for any reason, the cover and the cable plate without having first
disconnected the device from the main power supply and having waited at least 5
minutes.
VASCO and pumping system must be grounded properly before operation.
For the entire period VASCO is powered, high voltage is present on the output
terminals of the inverter whether or not the pump is running.
Tightening all 4 screws on the cover with washers is recommended before
powering the device. Otherwise, there may be a failure to connect the cover to
ground, creating the risk of electric shock or even death.
Avoid any shock or significant impact during transport.
Check the VASCO immediately upon delivery and check for damage and/or missing parts. If either occurs, immediately notify
the supplier.
Damages due to transport, incorrect installation, or improper use of the device will null and void the warranty.
Tampering or disassembly of any component will automatically void the warranty.
The manufacturer cannot be held responsible for any damages to people and/or property due to improper use of its
products.
