3.2 SETPOINT ENTRY 3.2.1 PROCEDURE
To store any setpoints, terminals C1 and C2 (access terminals) must be shorted (a keyswitch may be used for
security). There is also a setpoint passcode feature that restricts access to setpoints. The passcode must be
entered to allow the changing of setpoint values. A passcode of 0 effectively turns off the passcode feature – in
this case only the access jumper is required for changing setpoints. If no key is pressed for 5 minutes, access
to setpoint values will be restricted until the passcode is entered again. To prevent setpoint access before the 5
minutes expires, the unit may be turned off and back on, the access jumper may be removed, or the

ACCESS
setpoint may be changed to "
Restricted"
. The passcode cannot be entered until terminals C1 and C2
(access terminals) are shorted. When setpoint access is allowed, the SETPOINT ACCESS indicator on the
front of the 469 will be lit.
Setpoint changes take effect immediately, even when motor is running. However, changing setpoints while the
motor is running is not recommended as any mistake may cause a nuisance trip.
The following procedure may be used to access and alter setpoints. This specific example refers to entering a
valid passcode to allow access to setpoints if the passcode was "469".
1. The 469 programming is broken down into pages by logical groups. Press to cycle through the set-
point pages until the desired page appears on the screen. Press to enter a page.
2. Each page is broken further into subgroups. Press and to cycle through sub-
groups until the desired subgroup appears on the screen. Press to enter a subgroup.
3. Each sub-group has one or more associated setpoint messages. Press and to
cycle through setpoint messages until the desired setpoint message appears.
4. The majority of setpoint messages may be altered by pressing and until the desired
value appears and pressing . Numeric setpoints may also be entered through the numeric keys
(including decimals) and pressing . If the entered setpoint is out of range, the original setpoint value
reappears. If the entered setpoint is out of step, an adjusted value will be stored (e.g. 101 for a setpoint
that steps 95, 100, 105 is stored as 100). If a mistake is made entering the new value, pressing
returns the setpoint to its original value. Text editing is a special case described in detail in Section 3.1.6:
ENTERING ALPHANUMERIC TEXT on page 3–4. Each time a new setpoint is successfully stored, a mes-
sage will flash on the display stating "
NEW SETPOINT HAS BEEN STORED
".
5. Press the 4, 6, and 9 keys, then press . The following flash message is displayed:
and the display returns to
6. Press to exit the subgroup. Pressing numerous times will always returns the cursor to the
top of the page.
