INTRODUCTION

The GMDSS Interface is used for monitoring of the
accumulator battery and Mass charger of the backup
power supply for the radio installations. Battery voltage
and current can be made visible by means of an
integrated LCD-display and audible failure alarms are set
according to the regulations of the I.M.O.
The GMDSS Interface is intended for installations with
one battery bank and one Mastervolt Mass series battery
charger. If two chargers are required, Mastervolt
recommends the installation of two GMDSS interfaces.
The GMDSS Interface
indicators for indication of AC failure, charger failure and
low and high battery alarm. The GMDSS Interface is
equipped with three potential free change over contacts
to make a link to the ship's global alarm system. The
GMDSS Interface is standard equipped with an external
5V/50mA unregulated power supply for integration with
the ships global alarm system. The GMDSS Interface
offers the possibility to power external (LED-) indicators,
buzzer and external mute switch (alarm accept) directly.

STORAGE OF SET POINTS

The charger set points F8 till F12 (see section 3.3.2) are
stored into the EEprom memory of the Mass series
battery charger. In case off loss of AC or DC power, the
GMDSS interface reads back the set points which are
stored into the charger. This means that the GMDSS
interface will not loose the DC-alarm set points in case
AC or DC power failure.
Other set-points like display setting and charge current
% are stored into the memory of the GMDSS Interface
itself and may get lost in case of DC power failure.
