Using Front-Panel
Push-buttons
ASMi-450 operation is controlled by means of the display and the three push-
buttons designated CURSOR, SCROLL and ENTER. The same control actions
are consistently used for all the activities:
CURSOR Use this push-button to indicate what you want to change.
Pressing the CURSOR push-button moves the cursor among
the fields in the current display. The cursor is a bar that
appears under first character of the selected field.
Some fields list several different items, and then you move
the cursor under the desired item. The item displayed above
the cursor can be changed (“scrolled”) by pressing
SCROLL.
SCROLL Press repeatedly to display the alternatives for the current
field/item indicated by the cursor. Holding the push-button
depressed causes automatic scrolling of the available
alternatives.
ENTER Press it once to select the value displayed in the field/item
indicated by the cursor.
• If the selected value is valid, it replaces the old value
and the change takes effect immediately.
• If you make an incorrect selection, the selection is not
accepted. In this case, you see a CONFIG ERROR
message with a two-digit code in the second display
row. The code indicates what is wrong. After a short
time, the error message disappears and you see again
the original display. Now you can correct the error.
Section 3-8 explains the error codes and what to do to
correct the error.
The ENTER key has an additional function: when the alarm buffer is displayed,
the ENTER key can be used to delete all the alarms in the buffer.
