7 Setup and function
7.1 Standard package
The standard package includes:
IRflex vibrator head (optional).
FUflex inverter (optional).
Operator's manual.
The IRFUflex machine consists of two components:
IRflex vibrator head.
FUflex inverter.
7.2 Application areas
The internal vibrator is a machine used to de-aerate and compact freshly mixed (green) concrete.
7.3 Short description
High frequency oscillations are generated in the vibrator head. The vibrator head makes gyrations due
to these vibrations.
The immersion of the vibrator head in the freshly mixed (green) concrete de-aerates and compacts the
concrete in the operating area of the vibrator head.
At the same time, the freshly mixed (green) concrete cools the vibrator head.
7.3.1 IRflex vibrator head
An electric motor in a vibrator head drives an eccentric weight, thus producing gyrations. Through these
gyrations, the vibrator head directs vibrations into the concrete.
7.3.2 FUflex inverter
The inverter consists of a current rectifier and a DC–AC converter and is monitored by control
electronics.
The current rectifier converts the input voltage (single-phase AC) into DC voltage.
The DC–AC converter converts the generated DC voltage into current (3-phase AC).
When switching on the machine, the control electronics ensure a smooth start and therefore prevent the
emergence of critical switch-on currents.
7.3.3 Bodyguard®
The Bodyguard® connects the mains supply line with the converter and monitors the operating currents
flowing in and out. The Bodyguard® helps protect the operator from electric shock in case of failure
(leakage currents).
The indicator light illuminates in red when the machine is closed correctly and the machine functions
correctly.
The indicator light doesn't illuminate when a leakage current occurred inside the machine. In this case,
the mains side power supply is cut off and the converter locked.The machine does not operate. The
power supply remains cut off until the error is remedied. The Bodyguard® features a test button to check
the function of the Bodyguards®.
The machine only works in connection with the Bodyguard®.
7.3.4 Quickflex coupling
The Quickflex coupling makes it possible to separate the vibrator head with IRflex protection hose from
the FUflex inverter and replace it with a vibration head with a different sized diameter and hose length.
7.3.5 Thermal overload protection
The machine is protected against overheating. In case of overheating, the machine switches itself off
automatically.
NOTICE
The components, that are marked as optional must be ordered separately.
