PARTS LIST
M-0329B LTC Backup Control
This list includes all electrical and mechanical parts which could conceivably either require replacement or
be lost. The
COMPONENT DESIGNATION
is the same as that appearing on schematics or referred to in
Instruction Books.
The
BECO NUMBER
refers to an index maintained by the company. This lists the currently available device
which may be substituted even though the device originally supplied is obsolete and no longer available. Parts
marked by an asterisk* are not available from other sources. Either the original component or a current
substitute will be carried in stock by Beckwith Electric.
Parts not marked with an asterisk are normally available from an electronics components house. Those parts
or a current substitute will normally be available from Beckwith Electric stock.
In either case, when parts are ordered from Beckwith Electric, we will be responsible for supplying the current
replacement in the shortest possible time.
Sufficient detailed description is also given to permit purchasing from an electronics parts house, providing
the part is of equal or better quality to insure reliable operation. This may require some interpretation of
specifications which may be avoided by direct purchase from Beckwith Electric using the
BECO NUMBER
.
Note that in a few instances, components are selected in final test. Procedures described in the
TEST
PROCEDURES
Section must be followed in replacing these components.
All resistors are 1/2 W unless noted.
