PROGRAMMER SELF-TEST
You can test the programmer by displaying two special test screens. See Figure 4. Press and hold the
more info key while the programmer is powering up. During the self-test, you can toggle between the
two test screens by pressing the scroll display keys. The first screen turns on every LCD element, and
the second screen displays all the characters used in the various menus. As part of the self-test, you
can also test the keys by pressing each one and observing whether its corner LED lights up. To exit

MENU SELECTIONS
Program Menu
Press the program key to enter the PROGRAM mode. The LED in the corner of the program key
illuminates to indicate that the programmer has been placed in the PROGRAM mode. The adjustable
functions are shown in the display window, 4 at a time, with the corresponding settings. The setting of
the selected item (the item at the top of the display with the flashing arrow) can be changed using the
change value keys. The change value keys have LEDs to indicate whether the key can be used to
increase or decrease the value any further.
Press the more info key to display more detailed information for the setting selected, including a bar
graph indicating the position of the current setting relative to the range for the setting, the unit of
measure, and the specific minimum and maximum values for the setting. If the range is limited by the
values assigned for a different function, the name of the limiting function is displayed in place of the
minimum and maximum values.
Test Menu
NOTE: Some tests may not apply to all models.
Press the test key to enter the TEST mode. The LED in the corner of the test key illuminates to
indicate that the programmer has been placed in the TEST mode. The TEST menu displays real-time
information about the status of the inputs, outputs, and controller temperature. See Table 5. In the
TEST mode, the item of interest does not need to be the top item in the window; it only needs to be
one of the four items displayed in the window. The TEST mode is useful for checking out the operation
of the controller during initial installation. The more info key, when used in the TEST mode, displays
additional information about the top item in the window.
