The Systems Monitor consists of a Display Control
Module (DCM) located at the control station and a
Bilge Interface Module (BIM) located on the engine
room component board (See Fig. 6.5.1). The DCM
and BIM are connected to each other by a coax
cable and the BIM is continuously looking at all
inputs for an alarm condition.

The Systems Monitor is connected directly to the
12 volt battery bank through a circuit breaker and
continuously monitors two emergency high water
pumps, two bilge pumps and the bilge heat detector.
The engine and generator functions are only active
when ignition voltage is turned on. The circuit
breaker is on the main DC breaker panel located
on the engine room component board (See Fig.
6.5.1).
The BIM collects signals from critical engine
functions, generator oil pressure, bilge pumps, high
water emergency bilge pumps and bilge heat
detection and transmits that information to be
displayed on the DCM.
The features of the DCM include a two line LCD
display with backlighting of the display, audible
alarm and an Audible Reset/Alarm Select push
button switch.

The LCD display will read in two lines. For example,
at normal operation it will read:
SEA RAY BOATS
ALL SYSTEMS NORMAL
NOTE: Some functions only read on one line. See
page 2.21 (DCM functions) for all DCM display
readouts.
Backlighting of the LCD is achieved by turning ON
the navigation lights switch. Intensity is controlled
by the electronic dimmer control. Both are located
on the control station switch panel.

An audible alarm will sound to alert the operator to
look at the DCM and determine the high level fault.
Only high level faults such as critical engine
functions, generator, emergency pumps and bilge
heat detector will have an audible alarm. The forward
and aft bilge pumps do not have an audible alarm,
instead the DCM will display those functions.

CAUTION
Never ignore an alarm.

The Audible Reset/Alarm Select push button
switch on the DCM is a dual purpose switch. It
enables the operator to reset an audible alarm or to
manually scroll the display during multiple alarms.
The Audible Reset is used to temporarily quiet an
alarm that is displayed on the LCD. If that function
is not corrected within 30 seconds, the audible alarm
will sound again. Pushing the switch again will
permanently quiet (turn off) the audible alarm for
that function. The LCD will still display that fault until
it is corrected.
