. 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.
Cervomatic EDP.2 must be connected in vertical position with the inlet port ( 1 ¼" male) directly connected to the main pump
discharge, and the outlet port (1 ¼" male) to the main network.
Thread the accumulator tank to the back cover using an adequate sealing material.
Cervomatic EDP.2 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.
Table 1. Required cable dimensions

Power supply voltage
H07RN-F 3G1,5
Motor supply
H07RN-F 3G1,5
Use H07RN-F type cables of sections sufficient for the applicable power supply as given in Table 1.
Check power supply. Remove the cover of the control electronics and establish the connections according to the indications
located on the connection strip base.
Pumps with three-phase motors:
Power supply of control unit: connect L1, L2, L3 via a three pole motor protection switch (recommended) in OFF mode
and ensure proper connecting PE.
Motor: connect motor to U, V, W and PE (earth).
Pumps with single-phase motor:
Power supply of control unit: connect L1 and L2 via a motor protection switch (recommended) in OFF mode and ensure proper
earthing by connecting PE.
Motor: connect motor to U, V and PE (earth).
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.
Connect all auxiliary devices:
Alert monitoring: Cervomatic EDP.2 has 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.
Min. level control: there is an input for stopping all the pumps as soon as the external switch for minimum level detection trips. For
connection see Fig. 4.
For the voltage selection set the selector:
to A for 220-240 V.
to B for 380-415 V.
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.
Check rotational direction of the pump before
commissioning.

7. ACCUMULATOR PRESSURE.
The accumulator is pre-pressurised in the factory at 3,5 bars. It should be pressurised 0,2 bar below the configured start pressure of the
pump in pressure-dependent mode. If accumulator is not sufficiently pressurised: in MANUAL MODE open a tap and, using a bicycle pump
and adapter, pressurise the tank through the valve. Put the cap back on the valve. Push AUTO On/off.
8. STARTUP.
It is recommended to connect Cervomatic EDP.2 to the electric supply via the motor protection switch. Wait for 5 seconds while the
Cervomatic EDP.2 is running autotest.
If the unit is started for the first time, it will directly open the configuration menu. The LCD screen will display a message for language selection.
Choose your language and start the configuration procedure - see 7. CONFIGURATION.
Once the unit is configured, switch to manual mode by pressing the AUTO On/Off push-button (green LED off). Verify the rotational direction
of the pump, and whether it is correctly primed using the Start/Stop push-button.
Press AUTO On/off. The unit is ready to operate.
9. CONFIGURATION.
Values may be changed by using
press MENU. Each time ENTER is pressed, the different screens, which display the sequence of configuration, will open
automatically.

P ON" must be at least 0.2 bar higher than manometric pressure.
Eg: with 20 meters of water column
The pump must be able to supply at least 0.5 bar more than "P ON".
(2) Being in pressure dependent mode "P OFF" must be at least 0.5 bar lower than the pressure supplied by the pump.

motor. Press ENTER to confirm.
If there is no external device for detecting the minimum water level, press ENTER to
confirm. Otherwise, change NO for YES
In this step, the mode of operation can be selected using
OPERATING MODE
On-off mode: only the start pressure is configured. The pump will start at this
PRESSOSTATIC
pressure - with the delay configured in the next step - and it will stop when there is
no flow demand.
Pressure-dependent mode: the start and stop pressures of the pump can be
configured.
This is the start pressure for the pump. The desired pressure values within the respective
P ON
range can be chosen using the
05,0 bar
On-off mode: from 1 to 5 bars.
Pressure-dependent mode: from 0 to 6,5 bar.
This is the stop pressure for the pump in pressure-dependent mode. It must be within a
P OFF
range of
1 to 7 bar and 1 bar above the start pressure.
