Wiring installation in 4848 Reactor Controller (Continued)
4. Attach the 4-pin edge connector from the A2106E
to the “Tach In” (slot A). Align the empty spot on the
edge connector to the empty pin on the “Tach In” of
the A1695E excitation board. Reference the A1695E
Picture on page 3.
5. Find the 2 wire cable, black and white wires with
one end stripped and the other end has a 3 pin edge
connector as shown, and plug the 3-pin edge con-
nector to the “Tach Out” (slot A). The Orientation of
the black wire does not matter; the connection can
be plugged in either way.
6. The stripped end of the 2 wire cable attaches to
the 2084E meter. Take care not to apply too much
torque which could cause the wire to eventually
break. The meter’s pins are labeled 1-12, as shown.
The black wire from the A2106E harness attaches to
pin 6, and the white wire attaches to pin 4. (This may
already be connected for your convenience.)
7. Find the 2 wire cable with white and black wires
that has both ends stripped, and attach one end to
the 2084E meter. White wire #3 to terminal #11 and
black wire #4 to terminal #12. (This may already be
connected for your convenience.) The other end of
the white wire #3 attaches to terminal block position
#4 and the black wire #4 attaches to terminal block
position #3.
Note: The terminal block position can be opened up
using a small fl at head screw driver to release the
tension from the spring inside the block so you can
press the wire against the spring.
