Control Panels - Beta Marine Beta 50 Operator's Maintenance Manual

KEY SWITCH TERMINATIONS
The standard panel key switch can be used to tap off
a switched positive ignition feed to power additional
gauges. In this way these gauges will only be live whilst
the engine is running, the engine is starting or the heaters
are being used.
For silver key switches, the terminal to achieve this
ignition switched positive is marked 'AC'.
For panels with push buttons, gauges can be driven
from the 1mm 2 brown wire which terminates at 11 way
connector terminal 4. This is a lower power switched
positive, any additional power required from this
CONTROL PANEL INSTALLATION
All Beta Marine engines are supplied as standard with 12
volt electric starting. 24 volt electric starting is available as
an optional extra at placement of order.

CONTROL PANELS

Beta Marine offer 10 control panel options, standard for
heat exchange is the ABV panel, standard for keel cooled
is the AB or C panel. For further information please refer
to pages 24, 25, 46, 47 & 48.
1. Control Panels must be fitted in a location where the
helmsman can either see or hear the alarm system.
2. Control panels are supplied as standard with a 3m
multi-core cable for connection to the engine wiring
loom. Extension looms of 5m or more are available
should your installation require it or you wish to
relocate your existing panel/s, all looms include a start
relay to overcome the voltage drop.
3. For standard wiring diagrams see diagram index, page
52.
4. All electrical equipment must be protected from sea
water. Sea water or rust in the starter motor will
invalidate the warranty. Care must be taken when
pushing the two halves of the interconnection plugs
together to ensure that individual pins do not fall

connection must be feed through a relay.
NB: Key switch terminals are rated at 10 amps
maximum, since they are already utilised for panel and
alternator feeds Beta Marine recommend any additional
requirements from these terminals must be fed through
a relay. This relay should then be connected to it's own
fused positive supply directly from the engine battery.
