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trafc.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sufciently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.
