5. HYDRAULIC CONNECTION.
Check automatic control unit for transportation damage upon receipt.
Before hydraulically connecting the pump, it is essential to install a non-return valve at the pump´s
suction side.
ONEMATIC easy
must be connected in vertical position with the inlet port ( G1 ¼” male) directly
connected to the main pump discharge, and the outlet port (G1 ¼” male) to the main network.
ONEMATIC easy
has an integrated accumulator so that it is not necessary to install an external one.
However, if frequent flow consumptions are planned, it is recommended to operate in pressure-
dependent mode, and to install an external accumulator.
6. ELECTRIC CONNECTION.
The unit should be disconnected from the electric supply before performing any work inside the
unit.
Wrong connections may destroy the control electronics.
Use H07RN-F type cables of sections sufficient for the applicable power supply as given in Table 1.
n
Check power supply. Remove the cover of the control electronics and establish the connections according
to the indications located on the connection strip base.
n
Power supply of control unit
: connect
L
and
N
via a motor protection switch (recommended) in OFF
mode and ensure proper earthing by connecting PE.
n
Motor
: connect motor to
U, V
and
PE (
earth
).
n
The earth conductor must be longer than the others. It is the first one to to be connected during
installation, and the last one to be disconnected during dismantling.
n
Connect all auxiliary devices:
n
Alert monitoring:
ONEMATIC easy
could be provided (ON REQUEST) with a volt-free contact with 1 A
maximum intensity for the transmission of signals to diferent types of alarm equipment (optical, acoustic, etc)
when a failure, which was previously displayed in the LCD screen, is detected. For connection, see Fig.
4.
(OPTIONAL)
n
Min. level control:
ONEMATIC easy
could be provided (ON REQUEST) with an input for stopping the pump
as soon as the external switch for minimum level detection trips. For connection see Fig. 4.
(OPTIONAL)
When closing the cover after electrical
connection, ensure correct position of the cover
seal. Make sure that internal wires are not
clamped between the cover parts.
