They may be comprised of upper case letters, lower case letters,numerals, and a selection of special characters. The editing and storing of a textvalue is accomplished with the use of the decimal [.], VALUE, and ENTER keys.1.

Press the MESSAGE T key to view the SWITCH NAME setpoint. The name of thisuser-defined input will be changed in this example from the generic “GeneralSw. A” to something more descriptive.3.

The first character will appear underlined as follows:4. Press the VALUE keys until the character “S” is displayed in the first position. Nowpress the decimal [.] key to store the character and advance the cursor to thenext position. Change the second character to a “t” in the same manner. Con-tinue entering characters in this way until all characters of the text “Stn. Moni-tor” are entered. Note that a space is selected like a character.

Negative numbers may be entered in oneof two manners.– Immediately pressing one of the VALUE keys causes the setpoint to scrollthrough its range including any negative numbers.– After entering at least one digit of a numeric setpoint value, pressing theVALUE keys changes the sign of the value where applicable.Setpoint Entry To store any setpoints, terminals C1 and C2 (access terminals) must be shorted (akeyswitch may be used for security). There is also a setpoint passcode feature thatrestricts access to setpoints. The passcode must be entered to allow the changing ofsetpoint values. A passcode of “0” effectively turns off the passcode feature - in thiscase only the access jumper is required for changing setpoints. If no key is pressedfor 5 minutes, access to setpoint values will be restricted until the passcode isentered again. To prevent setpoint access before the 5 minutes expires, the unitmay be turned off and back on, the access jumper may be removed, or the SETPOINTACCESS setpoint may be changed to “Restricted”. The passcode cannot be entereduntil terminals C1 and C2 (access terminals) are shorted. When setpoint access isallowed, the Setpoint Access LED indicator on the front of the 469 will be lit.INPUT 1 FUNCTION:General Sw. ASWITCH NAME:General Sw. ASWITCH NAME:Stn. Monitor
