DISPLAY AND KEYBOARD
3-2
causes the following display:
USER LEVEL
END OF PAGE
This message indicates the end of the page and no more
lines are available. To move to the first line of the next page,
use the PAGE key.
If the relay is left in the setpoints mode with no key being
pressed for more than four minutes, the display changes to
the default page and line in actual values.
To enter or change setpoints a jumper or access key must
first be connected across terminals 33 & 34 and the setpoints
mode entered.
If an attempt is made to store a setpoint without enabling the
access terminals, the following message will appear:
ILLEGAL ACCESS
and the setpoint will not be stored. This prevents unauthor-
ized changing of setpoints. Stored values remain in the
Relay’s memory, even when control power is removed. The
ability of the relay to provide protection depends on the
values entered in the setpoints mode, therefore these values
should be complete, accurate and very carefully entered.
Once a setpoint is displayed and the access jumper is
installed, it can be changed by either:
1. Entering new numerical values from the Keypad and
storing them in the relay’s memory using the STORE key,
or
2. Making selections from a list of items using the NEXT
CHOICE key.
If the selection is to be made using the NEXT CHOICE key
then the 565/575 Relay will infor m you by flashing the
following message on the bottom line of the display:
Use NEXT CHOICE
The possible choices will appear in the display one by one,
each time the NEXT CHOICE key is pressed. When the last
item in the list is reached pressing the key again will cycle the
display through the choices again.
Display the required choice and enter the value into the
Relay’s memory using the STORE key. The following mes-
sage will appear for two seconds to indicate that the setpoint
has been stored by the Relay.
NEW SETPOINT
STORED
If the STORE key is not pressed the relay will keep the old
setpoint regardless of which choice is displayed.
The LINE DOWN key may now be used to move to the next
line of the setpoints page and further values entered as
described in the Setpoints Mode section.
When the end of a page in setpoints has been reached the
PAGE key can be used to view the setpoints on the next
page.
Help Mode
This display mode should be used whenever help is required
in using the 565 relay. It is entered by pressing the HELP key
while the display is on any line in any page. The HELP key can
provide information about the currently displayed actual value
or setpoint message. Pressing the HELP key has no effect
when a flash message or HELP message is on the display.
If the HELP key is pressed with the display on the first line of
page one the following message will appear:
PRESS ANY KEY
OR HELP
The user should then press the key for which instruction is
required or press the HELP key again to access information
on the previously displayed actual value or setpoint mes-
sage. When the desired key is pressed the display will show
the message:
PRESS LINE DOWN
TO SCROLL
The LINE DOWN key can then be used to display the HELP
message which will give information about the line or key in
question.
If the HELP key is pressed while displaying any line other
than a page header the HELP message shown will relate to
the line which was displayed when the HELP key was pressed.
This applies when the 565/575 Relay is in actual values or
setpoints.
Pressing the CLEAR key at any time during the help mes-
sage will return the display to the page and line of the mode
in effect when the HELP key was originally pressed. The
ACTUAL
VALUES and SETPOINTS keys may also be pressed
to exit HELP mode.
