.NQIES:

1. THE ROD CIRCUIT SHALL BE DESIGNED TO INSURE THAT:

A. ONLY ONE ROD ROD MAY BE SELECTED AT A TIME.

B. WHEN MOVEMENT IS INITIATED THE SELECTED ROD SHALL BE SEALED IN TO INHIBIT SELECTION OF ANOTHER ROD DURING THE MOVEMENT CYCLE (EXCEPT FOR THE LOSS OF CONTROL CIRCUIT POWER).

2. EACH CONTROL ROD, AS IT TRAVELS UP (INSERTED) OR DOWN (WITHDRAWN) PASSES BY A NUMBER OF SWITCHES.

THE TOP TWO POSITION SWITCHES ARE CALLED "OVERTRAVEL" AND THE BOTTOM TWO POSITION SWITCHES ARE CALL.ED "WITHDRAWN",

BACKSEAT AND DISCONNECT. SWITCHES IN BETWEEN ARE DIVIDED INTO ODD (DRIFT) AND EVEN (LATCH) POSITIONS.

AS THE ROD TRAVELS OVER ANY SWITCH AN INDICATING SIGNAL IS ACTUATED.

3. FOR LOCATION AND IDENTIFICATION OF INSTRUMENTS SEE INSTRUMENT DATA SHEET LISTED IN MPL FOR EACH INSTRUMENT.

4. _£ DESIGNATIONS LISTED ARE PER RPIS/RWM DATABASE.
