2.7.16 AUTO/MANUAL SWITCH 0

The Auto/Manual Switch 0 (AMS 0) module provides a continuous output signal that is derived
from one of three sources which are the output track value (OTV), control output auto value (CO),
or the manual push button value. The output priority is OTV, CO, and output push buttons. The in-
put variable parameter values also affect the output, as determined by the output selection made.
The two tables that follow list the input variables and the parameters. As shown in the third table,
two logical output signals, L105 and L107, indicate which source is supplying the continuous out-
put signal at C102. An illustration of the AMS 0 module follows the tables.
