Bulletin 639510 May 2005 9-3
9.3 Clearing All Alarms on
a Device
After examining the alarms status results,
any alarms found may be cleared using
the ‘Clear Alarms’ button.
1. Click on the device in the ‘Device In-
formation’ list that has an alarm to be
cleared.
2. Click on the ‘Clear Alarms’ button to
clear any current alarms that have
been declared by the device.
3. After all alarms have been cleared for
the device, a pop-up notification will
display to notify the user that all alarms
are clear (Figure 9-4).
4. Click ‘OK’ to dismiss the ‘Clear Alarms’
pop-up notification (Figure 9-4).

9.4 Executing a Self Test Movement for a Device
Andrew’s ATM200 actuators support the AISG self test command. This feature allows the
user to periodically perform a test by temporarily making a small tilt angle movement on the
device. This test enables the user to verify that the actuator’s motor is operational and capable
of adjusting electrical tilt on the antenna. The movement executed as part of the self test is
designed to be so small as to not disrupt the current data/voice traffic. The movement is +/-
0.2 degrees to either side of the current downtilt angle, with a return to the original downtilt
angle at the end of the movement.
Note that if the current downtilt angle on the antenna is sufficiently close to the minimum or
maximum possible angle, the actuator may modify the test movement range of motion or
ignore the test movement command altogether.
