terminals 1 and 2 (electromechanical version) or "Level" terminals
(electronic version).
Check the connection by actuating the float by hand to light the
dry-running indicator on the box.
Remoting
Depending on the characteristics of the installation, a signal may
have to be remoted. A dry voltage-free contact closing on faults is
provided for this purpose (general fault remoting):
Electromechanical version, terminals 6 and 13, max. permanent cur-
rent 4 A
Electronic version, "alarm output" terminals, max. permanent current
4 A
Remote control
The electronic version can be remotely controlled (remove the jum-
per and connect the "remote control" terminals).
6. STARTING UP
Never operate the module dry, even briefly.
6.1 Pressurization of tanks
With no water in the tank, pressurize the tank to a pressure 0.3 bar less
than the pump starting pressure (Pf).
Max. pressurization pressure:
Tank
3.9/7 bars
= 3 bars
10/15 bars
= 7 bars*
12/18 bars
= 8 bars*
16/24 bars
= 12 bars*
* Safety valves are mandatory on these models.
6.2 Pressure gauge (see Fig. 1)
Cut the nipple of the pressure gauge to vent it (item 3).
6.3 Filling, degassing
On town water network or under pressure from tank
- Check the water supply (tank full or town water supply correct).
- Open the feed valve of the module to fill with water.
- Unscrew the bleed-tap (1,5 to 2 turn) located under the caps (see
Figs. 1a and 1b, item 6) and wait for the water to flow out freely
before closing them.
- Set the selector switches of the pumps (see Fig. 2a, item 5) to "MAN"
to check the priming. If necessary, test the pumps one after the
other.
The booster must not be installed in suction
6.4 Check of direction of rotation
The pumps are connected to the control cabinet in the plant.
However, you should check the direction of rotation, proceeding as
follows:
ELECTROMECHANICAL CONTROL
Make sure that the equipment contains water.
Set the selector switches of the pumps to "O".
Close the general disconnecting switch. Position "I"
(the power on indicator lights).
Open the door of the box.
Set the Dry-running timer (RME) to zero (O)
Apply a starting pulse from the selector switch, with one pump set
to "MAN", then release.
(The indicator lights on the front panel and the pump turns briefly.)
Check the indicator light of terminal box (must be lighted).
YES
Direction of rotation correct.
Go to the next pump.
ELECTRONIC CONTROL
Make sure that the equipment contains water.
Close the general disconnecting switch. Position "I"
(the power on indicator lights).
Apply a starting pulse from the selector switch, with one pump set
to "MAN", then release.
(The indicator lights on the front panel and the pump turns briefly.)
Check the indicator light of terminal box (must be lighted).
YES
Direction of rotation correct.
Go to the next pump.
13
(Audible click).
NO
Direction of rotation reversed.
Open the general disconnec-
ting switch ("O").
Interchange two phase wires of
the power supply to the terminal
block of the motor concerned.
Close the general disconnec-
ting switch ("I").
NO
Direction of rotation reversed.
Open the general disconnec-
ting switch ("O").
Interchange two phase wires of
the power supply to the terminal
block of the motor concerned.
Close the general disconnec-
ting switch ("I").
