5. STEP KEYS
INC (INCREASE) key – This key has two functions:
a. Pressing this key while viewing position information
will command the associated primary device to move
in the UP or CLOCKWISE direction until the key is
released. Actual motion will depend on the current
state of the device and the controller.
b. Pressing this key while viewing the parameter list will
move up the parameter list by one entry, allowing the
user to scroll back through the parameter list.
DEC (DECREASE) key – This key has two functions:
a. Pressing this key while viewing position information
will command the associated primary device to move in
the DOWN or COUNTERCLOCKWISE direction until
the key is released. Actual motion will depend on the
current state of the device and the controller.
b. Pressing this key while viewing the parameter list will
move down the parameter list by one entry, allowing
the user to scroll forward through the parameter list
(same as pressing the PARAM key).
6. SCAN KEY AND INDICATOR
SCAN key – This key toggles the scan mode on or off.
When activated, the associated primary device will move
between the upper/clockwise and lower/counterclockwise
limits for the number of cycles specified by the scan cycle
parameter, P3 . See the “MODEL 2090 PARAMETER
LIST” for more information.
SCAN indicator – This indicator is lit as long as the scan
mode is activated.
