RC4000 ACU Boardset
ACU MODE LIGHT INDICATION
POWER UP Both Red & Green lights flash
MENU Both Red & Green lights on steady
(No errors)
LOCATE & Green light will flash a code indicating
STOW current sequence of mode
Red light off during normal operation
Red light flashes code if error has
occurred
MENU Green light steady on
Red light flashes error code from
(Error Detected)
previous mode
Therefore a typical sequence of operations would be:
1) as the ACU powers up, both green and red buttons flash
2) after power up initialization, both green and red buttons will be lit indicating the ACU is in MENU mode
3) the user presses the green button to initiate an automatic LOCATE. During the LOCATE operation the
red button is unlit and the green button flashes indicating normal operation.
4) after successful completion of the LOCATE operation, the ACU will return to MENU mode and both
buttons will again be steady on
5) the user presses the red button to initiate an automatic STOW of the antenna. During the STOW
operation the red button is unlit and the green button flashes indicating normal operation.
6) after successful completion of the STOW operation, the ACU will return to MENU mode and both
buttons will again be steady on
If an operational error was detected during a LOCATE or STOW function:
1) the green button would flash indicating what part of the sequence the mode was in
2) the red button would flash a code indicating the nature of the error. NOTE: typically a detected error
would automatically stop antenna movement as a normal function of the LOCATE or STOW mode
3) the user could press either button to return the ACU to MENU mode. In MENU mode the green button
would be steady on and the red button would flash the error code previously encountered. The user
could press either button to attempt the automatic function again.
NOTES
- if the ACU has not been placed in VSAT mode, neither button will be lit or active
- in general it is hoped that the user will become accustomed to recognizing that when the two buttons are
both lit a LOCATE may be initiated by the green button and a STOW initiated by the red button. While
