Assignment
(340AJ, 400S, 450AJ) The UGM no longer detects open circuit;
The UGM shall suspend Full speed Telescope In and Out permitted
Telescope In and Out after controls are initialized
(18RS, 24RS) The UGM
shall suspend Telescope In
and Out command and
revert to Open Loop Cur-
rent control for Telescope
The UGM shall limit Tele-
scope In and Out to Creep
speed after controls ini-
tialized
The UGM shall prohibit Power Cycled
Telescope Out;
Tele In speed limited to
Creep
