Introduction:
The Motorised Battery Switch has the same mechanism as the well proven part number
4640. The essential difference being the switching action has been motorised.
This permits switching of battery banks remotely. A typical installation is a key operated
switch at the helm station and the motorised battery switch installed as close as practical to
the battery bank.
Apart from the convenience of such an installation, this arrangement permits much shorter
cable runs to starter motors and other high current applications such as bow thrusters and
inverters. As a result voltage drop and use of heavy cable can be kept to a minimum.
General Operation:
The Motorised Battery Switch has two modes of operation, auto and manual. There is a LED
located on the battery switch indicating battery switch status.
Auto Operation:
The 4724 moves from a state of “Auto Off” to “Auto On” when the remotely
mounted switch is turned on. During the time that the battery switch is in “Auto
On” mode, the “Auto On” LED is illuminated.
Auto operation of the Battery Switch is not possible whilst in manual mode. If auto
operation is attempted, the LED will flash
for 3 seconds then stop. Knob must be returned to “Auto Off” before normal auto
operation can continue.
Manual Operation:
The automatic operation of the battery switch can be overridden at anytime by
depressing the control knob and turning clockwise towards the “Man On” position
or counter clockwise towards the “Man Off” position. During the time that the
Battery switch is in “Man On” mode, the “Man On” LED is
Illuminated.
