Electrical Installation - Vetus MV24A Série Manuel D'utilisation Et Instructions D'installation

3 Electrical installation

Ascertain whether the voltage listed on the
electrical control element matches the on-
board voltage.
Connect the electrical ball valve control ac-
cording to the electrical circuit diagram.
Include a main switch and a fuse in the 'posi-
tive' (+) wire.
Use a 6-wire cable with a minimum cross-sec-
tion of 0.25 mm 2 (22 AWG) between the ball
valve and the switch or the control panel.
Never change the settings of the limit switches.
The ball valve and the electrical control ele-
ment belong together. Never exchange any of
these components by installing a different ball
valve or another control element!
If the ball valve is installed in a fuel pipe (pet-
rol or diesel), the metal parts of the ball valve
must be earthed.
The system of protection of the electrical con-
trol element is IP67, provided that the swivel
and the flange are correctly assembled.
4 Maintenance
The drive is lubricated for lifelong operation
under normal operating conditions.
If the ball valve is applied as a cut-off for sea-
water and the ship is in an area where much
shellfish growth can be found, it is highly rec-
ommended to regularly open and close (or
close and open) the ball valve.

5 Operation
• Activate the main switch.
If the ball valve is controlled by a switch
(ELVPAN12 or ELVPAN24):
• To open:
Push the switch on the control panel to
the right. After several seconds (12 resp. 25
seconds, depending on the type), the right-
hand lamp will light up to confirm the open-
ing of the ball valve.
• To close:
Push the switch on the control panel to the
left. After several seconds (12 resp. 25 sec-
onds, depending on the type), the left-hand
lamp will light up to show that the ball valve
is now closed.
• If the ball valve is controlled by a waste
water control panel (WWCP):
Follow the directions stated in the manual
included with the WWCP.
Avoid leaving the ball valve in a partially open
position.
So never set the switch in another position be-
fore the appropriate light, which indicates that
the ball valve is completely open or closed, is
lit.
• Turn off the main switch if you are leaving
the ship.
