Galaxy Vector Controller GCM2, GCM3
Issue 4 January 2008 Product Description 2 - 5
Three alarm status LEDs give a visual indication of system
status. The Major and Minor alarm LEDs indicate when alarms
are present, and then the actual alarm descriptions can be
displayed on the LCD by pressing the Alarms softkey. LED
indications are described in Table 2-C.
Table 2-C: Control Panel LEDs and Functions
LED Indication
MAJOR (red)
A Major alarm is active. If the MAJOR LED is lit,
MINOR and OK LEDs will not be lit.
MINOR (amber)
A Minor alarm is active. If the MINOR LED is lit,
there are no Major alarms active and the MAJOR
and OK LEDs will not be lit.
OK (green)
No alarms are active. If the OK LED is lit, MAJOR
and MINOR LEDs will not be lit.
The default screen displays system voltage and current, system
mode (FLOAT or BOOST and other system conditions), and any
active alarms. The display will return to the default screen from
any menu whenever there has been no user initiated activity for
three minutes.
All power system attributes are characterized into three main
categories by the Vector Controller:
• Status
• Operations
• Configuration
as shown in Figure 2-5. Under Configuration are all of the
system parameters that can be edited.
Configuration edit screens have values and settings that can be
customized. There are two types of edit screens, numeric and
scroll lists. Numeric edit screens are those on which you modify
numbers by changing the individual digits in the number. An
example is the Float Set Point screen. Scroll list edit screens are
modified by pressing the UP and DOWN buttons to scroll
through a list of possible settings. These lists may include
numeric values or text. Selecting a Shunt Type is an example of
a scroll list edit.
