Keypad
The keypad consists of four pushbuttons named ENTER, SELECT, INC, and
DEC.
ENTER Key
The ENTER key is used to exit PARAMETER EDIT MODE and return to
PARAMETER SELECT MODE while saving the parameter’s new value to
nonvolatile memory. Nonvolatile memory is where parameter values are stored so
that they are remembered even when the controller is not being powered. In
PARAMETER SELECT MODE, pressing the ENTER key displays the version
number of the controller’s programming.
SELECT Key
The SELECT key is used to enter PARAMETER EDIT MODE from PARAMETER
SELECT MODE once a particular parameter has been selected for editing.
The SELECT key is also used to escape from PARAMETER EDIT MODE and
return to PARAMETER SELECT MODE without saving a change in a parameter’s
value. The value a parameter had when PARAMETER EDIT MODE was entered
is restored.
INC (increase) Key
The INC key is used to increase the displayed value.
