does not require a hardware EPROM change. 3.1.4 KEYPAD a) DESCRIPTION 469 messages are organized into pages under the headings Setpoints and Actual Values. The key navigates through the programmable parameters page headers. The key navigates through the measured parameters page headers. Each page is broken down further into logical subgroups of messages. The and keys may be used to navigate through the subgroups. The key is dual purpose. It is used to enter the subgroups or store altered setpoint values. The key is also dual purpose. It may be used to exit the subgroups or to return an altered setpoint to its original value before it has been stored. The and keys scroll through variables in the setpoint programming mode and increment/decrement numerical setpoint values. Alternately, these values may be entered with the numeric keypad. The key may be pressed at any time to display context sensitive help messages. b) ENTERING ALPHANUMERIC TEXT To customize the 469 for specific applications, custom text messages may be programmed in several places. One example is the Message Scratchpad. To enter alphanumeric text messages, the following procedure should be followed: For example, to enter the text "Check Fluid Levels": 1. Press the decimal key [.] to enter text editing mode. 2. Press the or keys until C appears, then press the decimal key [.] to advance the cursor. 3. Repeat step 2 for the remaining characters: h,e,c,k, ,F,l,u,i,d, ,L,e,v,e,l,s. 4. Press to store the text message. c) ENTERING +/– SIGNS The 469 does not have ‘+’ or ‘–’ keys. Negative numbers may be entered in one of two manners. • Immediately pressing the / keys causes the setpoint to scroll through its range including any negative numbers. • After entering at least one digit of a numeric setpoint value, pressing the or keys changes the sign of the value where applicable.

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 SETPOINT 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 LED 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
