CHAPTER 4: INTERFACES
The 469 does not have ‘+’ or ‘–’ keys. Negative numbers may be entered in one of two
manners.
 Immediately pressing one of the
VALUE
keys causes the settings to
scroll through its range including any negative numbers.
 After entering at least one digit of a numeric settings value, pressing
the
VALUE
keys changes the sign of the value where applicable.
4.1.6 Settings Entry
To store any settings, terminals C1 and C2 (access terminals) must be shorted (a keyswitch
may be used for security). There is also a settings passcode feature that restricts access to
settings. The passcode must be entered to allow the changing of settings values. A
passcode of “0” effectively turns off the passcode feature - in this case only the access
jumper is required for changing settings. If no key is pressed for 5 minutes, access to
settings values will be restricted until the passcode is entered again. To prevent settings
access before the 5 minutes expires, the unit may be turned off and back on, the access
jumper may be removed, or the
SETTINGS ACCESS
settings may be changed to “Restricted”.
The passcode cannot be entered until terminals C1 and C2 (access terminals) are shorted.
When settings access is allowed, the settings Access LED indicator on the front of the 469
will be lit.
Settings changes take effect immediately, even when motor is running. However, changing
settings 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 settings. This specific example
refers to entering a valid passcode to allow access to settings if the passcode was “469”.
