Check Of Direction Of Rotation - salmson ALTI-V ELINOX-V 36 Manuel D'installation Et Mise En Service

ENGLISH
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):
Automat version, terminals 6 and 13, max. permanent current 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
ATTENTION !
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.
- Open the filling plugs (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.
In suction on tank
- Close the discharge valve.
- Open the suction valve.
- Unscrew the filling plugs and remove them.
- Unscrew the drain-priming plug (item 7) 4 or 5 turns to interconnect
the suction and discharge casings.
- Use a funnel in the opening to fill the pumps and the suction piping,
slowly and completely.
- After water runs out and there is no more air, filling is complete.
- Screw the filling and drain-priming plugs (see Figs. 1a and 1b, item
6) back in.
- 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.

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:
AUTOMAT 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).
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 direction of rotation during the stopping phase.
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 direction of rotation during the stopping phase.
Direction of rotation correct.
Go to the next pump.
15
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").
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").
