Signals Cables Connection; Operating Modes; Configuration; Start-Up - Espa CKE Serie Manual De Instrucciones

The leakage to ground value depends on the number
of equipment units connected to the line and their
power rating.
Motor power
0.75 to 3 kW
4 to 5.5 kW
The electrical installation should have a multiple
separation system with contact gaps > =3 mm.
The set is fitted with one magneto-thermal switch per
pump on the connections panel.
The power supply input must be:
CKE...M
ESD
(single-phase)
CKE...
ESD
(three-phase)
CPE...M
ECD
(single-phase)
CPE...
ECD
(three-phase)

instructions of the corresponding controller

3.4. Signals cables connection

The signals connections are made at factory. Their
wiring diagram are explained in the ESD manual.

4. OPERATING MODES

Automatic mode
It is the usual operating mode.
The ESD controls the motor's rotation speed in order
to maintain constant pressure within the installation
(the consigned pressure).
The ECD controls the start and the stop of the pumps
depending on the introduced parameters of the start
pressure and differential pressure of stop (fault
1.5bar).
Manual mode
The ESD control allows for manually starting and
stopping the pump at an adjustable frequency.
The ECD allows the start and stop of the main pump
or of the auxiliary ones in manual mode.
Leakage current
< 3.5 mA
< 5 mA
230V10% 50/60Hz
50/60Hz
400V10%
50/60Hz
230V15%
50/60Hz
230/400V15%

5. CONFIGURATION

For equipment configuration, refer to the Speedrive
and/or SLV installation manuals

6. START-UP

6.1. Verifications prior to initial start-up

Make sure the mains frequency and voltage
correspond to those indicated on the characteristics
plate on the pumps.
Prime the set by completely filling the suction
manifold and the pumps with water, through their
priming cap, ensuring that there are no leaking joints
or connections.
Verify the pressure of the expansion vessel.
NEVER RUN THE SET DRY.
6.2. Start-up
Open all the closing valves in the suction and
discharge circuits.
Connect the electric power supply.
ESD
The ESD will enter into manual mode. For
configuration follow the ESD manual.
Check that the motor turns in the direction shown on
the fan cover. If it is turning in the wrong direction in
a pump fitted with ESD, correct this in the
corresponding menu, in a pump fitted with ELV
reverse the two phases on the set's connections
panel.
ECD
The ECD will enter on the initial screen. Make
settings of the starting pressure and the differential
pressure in the main pump controller. The start of
other pumps already comes fitted by fault. For
configuration follow the ECD manual.
If the motor does not start or does not pump water,
try to discover the cause of the irregularity in the list
of most frequent problems and possible solutions
provided later in this manual.

7. MAINTENANCE

Regularly verify the pressure of the accumulator.
The pumps do not need any specific or programmed
maintenance.
The panels or controllers require no maintenance.
Repairs should only be made by qualified technical
personnel. Use original parts.
