DISPLAY AND KEYBOARD
3-4
This section describes the front panel controls and indications. The “No.” column gives the number of each of the keys and
indications shown in Figure 4.1. The “Name” column shows the name of the key or indicator in question and the description
column gives information about the use of the key or indicator.
Number Name Description
1 The ACTUAL VALUES key allows the user to examine all the information in the pages of actual
values described in the ACTUAL VALUES MODE section. Pressing this key causes the following
message to appear, which indicates the first line of page one of the Actual Values mode:
ACTUAL VALUES
CURRENT
2 The SETPOINTS key allows the user to examine and change all the user-programmable setpoints
in the pages of setpoint data as described in the SETPOINTS MODE section. Pressing this key will
cause this message to appear, also indicating the first line of page one of the Setpoints mode:
SETPOINTS
USER LEVEL
3,4 These keys allow the user to view the previous or next line of the current page, as indicated by the
arrow pointing up or down respectively. If either key is held pressed for more than two seconds then
the next or previous lines will be displayed at a fast rate. If the display already shows the last line of
any page then pressing the LINE DOWN key will cause the following message to be displayed:
END OF PAGE
5 The PAGE key allows the user to move from any line in a page to the first line in the next page. For
example, if you are currently viewing any line in page 2 of the Actual Values mode, pressing this key
will cause the display to move to the first line of page 3, Actual Values. If this key is pressed on the
last page of either Actual Values or Setpoints then the display will move to the first page of that
section. As with the LINE keys, holding down the PAGE key will cause the pages to be displayed
rapidly.
6 The STORE key is used to store all new setpoints in the 565/575 Relay’s memory. When this key is
pressed, the value being displayed will be stored as a new setpoint in the relay’s memory and the
following message will appear for 2 seconds (provided the Access jumper is installed):
NEW SETPOINT
STORED
The numeric keypad or the NEXT CHOICE keys are used to display the correct value as seen later.
The STORE key can only be used to store data within the ranges accepted by the 565/575 Relay.
It is also used to set the default display in actual values as described in the Actual Values Mode
section of this manual.
7 The RESET key returns the trip or any latched output relay to its inactive state and extinguishes the
associated LED after a fault condition has caused it to become active. This key will only be effective
if the fault condition has been removed. Otherwise, resetting will not be possible and pressing the
key will result in one the following messages:
RESET IMPOSSIBLE
FAULT PRESENT
