2-20. Remote Control and Monitoring Circuits
Remote Control/Monitor Assembly 3A1 consists of two
meters (M1, M3) operated in parallel with CRYOGENIC
TEMP meter 1M1 (one for each channel), two meters
(M2, M4) operated in parallel with PARAMP ELAPSED
TIME meter 1M3 (one for each channel), and a split
pushbutton switch (S1) assembly (CHIANNEL SELECT)
that permits the operator to switch control voltage (28 3
Vdc) to Waveguide Switches 3A2 and 3A3 and contains
indicating lamps that identify the circuit (Channel I or
Channel 2) in use. Serial No. 001, in addition, contains a
toggle switch (S2) (NOISE DIODE) that permits the
assembly 3A13 (used in Serial No. 001 only), thereby
generating a noise signal that is supplied to the standby
channel through Waveguide Switch 3A2 port 3. All
meters and switches are panel mounted. Primary power
to Assembly 3A1 is 28 d 3 Vdc, which is supplied from an
external source, not part of the AM-6602/MSC-46(V)
system.
