Locator Control or Indicator Function
D FUNC/DATA - Continued When the relay is powered up, the display will default to
the DATA mode. Crossing from one mode to the other,
and entering/modifying the data is described briefly
below (locators I, J), and in detail in Section 4.
When the display exhibits the word dAtA for 60 seconds,
the display will automatically begin scrolling through the
instrumentation registers in a fixed sequence. After
stepping through all of the DATA registers, the display
wraps around to repeat the sequence until instructed
otherwise. (This process is covered in detail beginning
on page 4-4.)
E RS-232 PORT
(Supplied with the
communications option.) Provides connection for any RS-232 device that is to be
used for reading or loading the relay registers.
(Reference the interconnection diagram of Figure 5-1.)
F GROUND TMG Indicator An LED that illuminates when the preset ground over-
current pickup point is exceeded.
G GROUND TAP Selector A ten-position switch that provides an incremental
adjustment of the ground current pickup point. The
switch positions are defined for both HIGH and LOW
range in a table printed on the front panel (locator O).
(Intermediate settings between the switch positions may
be established by the Tap Cal register.)
H STATUS Indicator An LED that illuminates whenever the relay is in the
CONFiguration mode.
I MODE/NEXT Switch Holding this switch in the MODE position (up) for
approximately 5 seconds when the word DATA is
exhibited on the FUNCT/DATA display (locator D)
selects the CONFiguration mode. Holding the switch in
the MODE position for 5 seconds when CONF is
displayed selects the DATA mode, and also loads data
changes (if any) into memory. (The loading process is
explained in further detail on page 4-3.)
When neither DATA nor CONF is on display, holding the
switch up in the MODE position identifies the register
whose contents were on display immediately before the
switch was operated.
Each time the switch is toggled to the NEXT position
(down), the display advances to the next function in the
sequence (if the DATA mode was selected) or to the next
operating parameter (if CONF was selected).
J UP/DWN Switch Active in the CONFiguration mode only: Increments (if
raised) or decrements (if depressed) the value of the
displayed register.
