Description
FUNCTION: The VALUE UP and VALUE DOWN keys allow the user to alter the
currently selected setpoint. If either key is held for more than 1/2 second the set-
point selected will increment or decrement at a fast rate. If either key is held for
more than 2 seconds the setpoint selected will increment or decrement at a very
fast rate.
EFFECT: Pressing the VALUE UP key will cause the currently displayed setpoint
value to increment. Pressing the VALUE DOWN key will cause the currently dis-
played setpoint value to decrement. For YES/NO questions, pressing either key will
cause the answer to change. Any changed setpoint will not be used internally until
the STORE key is pressed.
USE: These keys can be pressed any time a setpoint is displayed in SETPOINTS
mode or when a YES/NO question is displayed in ACTUAL VALUES mode (see
STORE key). When the desired setpoint value is reached the STORE key is used to
save it. If an altered setpoint is not stored the previous value will still be in effect.
FUNCTION: The RESET key allows the user to reset the 269 after any of the
latched output relays have become active so that a motor start can be attempted.
EFFECT: Pressing this key will reset (ie. return to an inactive state) any of the ac-
tive output relay contacts if motor conditions allow (see below). The message,
RESET NOT POSSIBLE - RESET NOT POSSIBLE -
Condition still present Condition still present
will be displayed if any active output relays cannot be reset
USE: A latched relay cannot be reset if the trip/alarm condition persists (eg. an
OVERLOAD TRIP lock-out or a high RTD temperature).Pre-trip motor values may
be viewed in ACTUAL VALUES mode page 5 (Pre-trip Data). If an immediate re-
start is required after an OVERLOAD or INHIBIT LOCKOUT the Emergency Restart
terminals (see section 2.12) may be shorted together. This will reduce the lock-out
time to 0 minutes.
FUNCTION: In SETPOINTS mode the CLEAR key allows the user to return an al-
tered, non-stored setpoint to its original value. In HELP mode the CLEAR key al-
lows the user to return to the previous display mode.
EFFECT: When this key is pressed in SETPOINTS mode any altered, currently
displayed setpoint will be returned to its original value. When this key is pressed in
HELP mode the relay will return to the line and page of the mode active when the
HELP key was pressed.
USE: This key can be used in SETPOINTS or HELP modes only. In SETPOINTS
mode it can only be used when a displayed setpoint has been changed with the
VALUE UP/VALUE DOWN keys but has not yet been stored. After a setpoint has
been stored the CLEAR key will have no effect. In HELP mode the CLEAR key can
be used any time there is a HELP message on the display.
