Coelbo SPEEDBOARD 1305 TT Instructions Pour L'installation Et L'emploi page 8

MECHANICAL INSTALLATION (fig.2 and fig. 3)
•
Store in a clean and dry environment, do not remove the unit from its packaging until it must be used.
•
The device must be installed in environments pollution grade 2 according to EN-60730-1.
•
The protection degree is IP65 depending on the pump´s motor therefore must be mounted in places protected
from the rain.
•
Install the device to the connection box of the motor. As there are several types of connection boxes this ope-
ration could be done directly or using specific adaptors.
•
According to EN 61800-5-1 the unit must be installed in a closed electrical operating area.
HYDRAULIC INSTALLATION (fig.2)
Before proceeding with hydraulic connection it is essential to install a non-return valve in the pump´s inlet.
In case of assembly in group, it must be mounted a collector for the communication of the devices water outputs.
The inlet must proceed from a common origin.
For mounting the pressure sensor can be used any outlet G1/4 "at the pipe after the pump outlet.
It must be installed an hydropneumatic tank of at least 5 l to avoid problems caused by leakeages in the hydraulic
net
The device is provided with an automatic system that stops the pump if there is no demand in the installation. If you
are in an installation where the device does not stop the pump when there is no demand, this happens because the-
re are leaks in the installation (tanks, faucet, check valves...). In these cases it can be used the frequency minimum
value like a frequency stop. (see CONFIGURATION)
PROCEDURE: Open a faucet of the installation and set the desired minimum flow. With this flow, visualize in the screen
the frequency at which the pump is rotating. Set the minimum frequency to the frequency displayed on the previous
screen.
ELECTRIC CONNECTION (fig.3, 4 and 5)
The electrical installation must be performed by qualified personal in compliance with safety regulations and to
regulations of each country.
Before doing manipulations inside the device, it should be disconnected of the electric supply and after disabling,
wait for 2 minutes in order to avoid electrical discharges.
The basic unit is served with power cabling, motor cabling and pressure transmitter cabling. The power cord can be
replaced only by the manufacturer or his accredited representative.Then the cabling is exposed as would be done
to address any eventuality:
•
Use cables type H07RN-F with section enough to the power installed:
•
Power supply: s ≥ 1 mm
•
Motor supply: s ≥ 1 mm
•
Verify if the power supply is 400 V (230V*). Dismount the cover of the electronic circuit and carry out the con-
nections according to the indications located on the connection strip base.
•
Do the power supply connection (being sure there is a good earth connection): L1 L2 L3
by mean of magnetothermic switch in OFF mode. The earth conductor must be longer than the others. It will
be the first one to be mounted during the assembly and the last one to disconnect during disassembling.
•
Do the pump connection (fig.3-4).
•
Normally the device is served with the pressure transmitter connected with cable length of 1.5 m. Otherwise,
connect the pressure transmitter (fig.4-5). H03VV 2x0, 5mm cable is used.
If is necessary to increase the cable length, outer joint is performed following the guidelines of the regulations
applicable to low voltage installation country - the cable length should not exceed 15 m.
Do the pressure transmitter connection (fig.4 and 5). In case of M-S communication it will be connected a
pressure transmitter in each unit.
•
Do the connection of auxiliary devices:
•
Min. level control (optional). There is an input for stopping the pump as soon as is disconnected the
external switch of minimum level. See fig.5
•
Min. level control in case of master-slave communication (optional): both units must be connected at the

same level control. It is very important do not cross the polarity in both connectors. See fig.5.
•
Connection of 2 devices (optional): for the communication of 2 devices it will be used a cable of 4x0.25

mm2, it will be inserted throw the PG cable gland located in the lateral of the device. See fig.5.
WARNING!. Wrong connections could spoil the electronic circuit. The manufacturer declines all responsability in
damages caused by wrong connection.
START UP (SINGLE DEVICE).
• Be sure that the pump is correctly primed
• Connect the device to the electric supply with the magnetothermic switch, FAILURE led light will be ON. Wait
for 10 seconds while the device is doing the autotest. Once it finishes, led light FAILURE is OFF and led light LINE
is ON. The LCD screen will show message "SPEEDBOARD " and inmediately the language display of the configu-
ration mode.
• The device is ready for being configured.
