3.1.8 SETPOINT
ENTRY
In order to store any setpoints, terminals C1 and C2 (access terminals) must be shorted. (A key switch may be used for security). There
is also a Setpoint Passcode feature that may be enabled to restrict 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 and 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: Permitted 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 SR469 unit will
be lit.
Setpoint changes take effect immediately, even when motor is running. It is not recommended, however, to change setpoints while
motor is running as any mistake could cause a nuisance trip.
The following procedure may be used to access and alter any setpoint message. This specific example will refer to entering a valid
passcode in order to allow access to setpoints if the passcode was '469'.
1.The SR469 programming is broken down into pages by logical groups. Press [SETPOINTS] to cycle through the setpoint pages until
the desired page appears on the screen. Press [MESSAGE t] to enter a page.

4.The majority of setpoint messages may be may be altered in a simple fashion by pressing [VALUE s] and [VALUE t] until the desired
value appears and pressing [ENTER]. Setpoints that are strictly numeric may also be entered by pressing the numeric keys (including
decimals) and pressing [ENTER]. If a setpoint is entered that is out of range, the original setpoint value will reappear. If a setpoint is
entered that is out of step, an adjusted value will be stored (e.g. 101 for a setpoint that steps 95,100,105 will store as 100). If a mistake
is made entering the new value, pressing [ESCAPE] will cause the value to revert to its original value. Text editing is a special case
described in detail in 3.1.7 En/– Signs. Each time a new setpoint is successfully stored, a message will flash on the display
stating 'NEW SETPOINT HAS BEEN STORED'.
