2.1
Front Panel Controls and
Indicators
This section describes the operation of the M-3311A
as a function of the M-3931 Human Machine Interface
Module (HMI) and the M-3911A Target Module.
The M-3311A can be interrogated locally with the
HMI panel. An integral part of the design is the
layout and function of the front panel indicators and
controls, illustrated in Figure 2-1.
Alphanumeric Display
The HMI module consists of a 2 x 24-character
alphanumeric display. To assist the operator in
operating and interrogating the relay locally, the
HMI displays menus which guide the operator to
the desired function or status value. These menus
consist of two lines. The bottom line lists lower case
abbreviations of each menu selection with the chosen
menu selection shown in uppercase. The top menu
line provides a description of the chosen menu
selection.
Screen Blanking
The display will automatically blank after exiting
from the Main Menu, or from any screen after five
(5) minutes of unattended operation. To wake up the
display, the user must press any key except
EXIT
.
Arrow Pushbuttons
The left and right arrow pushbuttons are used to
choose among the displayed menu selections. When
entering values, the left and right arrow pushbuttons
are used to select the digit (by moving the cursor)
of the displayed setpoint that will be increased or
decreased by the use of the up and down pushbuttons.
The up and down arrow pushbuttons increase or
decrease input values or change between upper and
lower case inputs. If the up or down pushbutton is
pressed and held when adjusting numerical values,
the speed of increment or decrement is increased.
If the up or down arrow pushbutton is held in the
depressed position when adjusting numerical
values, the speed of the increment or decrement is
increased, after a small delay.
EXIT Pushbutton
The
EXIT
pushbutton is used to exit from a displayed
screen and move up the menu tree. Any changed
setpoint in the displayed screen will not be saved if
the selection is aborted using the
EXIT
pushbutton.
ENTER Pushbutton
The
ENTER
pushbutton is used to choose a
highlighted menu selection, to replace a setting
or other programmable value with the currently
displayed value, or to move down within the menu
tree.
RELAY OK LED
The Green
RELAY OK
LED is controlled by the
unit's microprocessor. A flashing
RELAY OK
LED
indicates proper program cycling. The LED can also
be programmed to be continuously illuminated to
indicate proper program cycling.
Time Sync LED
The green
TIME SYNC
LED illuminates to indicate
that the IRIG-B time signal is being received and
validated.
Breaker Closed (BRKR CLOSED) LED
The red
BRKR CLOSED
LED illuminates when the
breaker status input (52b) is open.
Diagnostic LED (DIAG)
The diagnostic LED flashes upon the occurrence of
a detectable self-test error. The LED will flash the
Error Code Number. For example, for error code 32,
the LED will flash 3 times, followed by a short pause,
and then 2 flashes, followed by a long pause, and
then repeat. For units equipped with the HMI, the
Error Code Number is also displayed on the screen.
