Subsystem History:

Date	Time	Component	Description
05/15/2007	18:18:00	SCAN MOTOR	High temperature saftey macro was initiated to turn off the MSU scan motor.
05/07/2007	09:00:00	SCAN MOTOR	7 May 2007 scan mechanism began to behave anomalously. The overall scanner position data maintained a pattern similar to its pre-anomaly pattern, but it became more erratic. It also covered a slightly larger range than it had pre-anomaly.
09/28/2006	17:03:00		Major spacecraft attitude perturbation resulted in autonomous battery undervoltage safing macro implementation turning off MSU.
03/20/1997		SCAN MOTOR	MSU Macro loaded to turn off scanner if DICKIE1 temp exceeds 24 degs.
03/30/1995		ANTENNA	MSU S/W patched to detect stuck antenna and turn scanner off for 6 secs. Macro to turnoff scanner if temp >22 degs
03/03/1995		SCAN MOTOR	MSU scanner ceased. Digital encoder failed, Turned OFF 3/15/95
