a. (cont)
g. If less than 0.15 vac is present between
NOISE TP and REFERENCE TP and
there is still no alarm, check between
BALANCE TP and REFERENCE TP.
The meter needle should fluctuate
above and below some point on the
scale.
h. If meter does not fluctuate, check
wiring for open circuits and shorts-
to-ground.
(1)
To check for an open circuit, dis-
connect wires from TB2-3 and
TB2-4 in the Processor and
TB1-3 and TB1-4 in the Trans-
ceiver. Ground each wire at one
end of the conduit. At the other
end, use the multimeter set on
ohms to check between the
wire and conduit. A low or zero
indication means a good wire; an
indication of infinity means an
open wire.
(2)
To check for shorts-to-ground, dis-
connect both ends of each wire.
Set the multimeter to ohms, and
check between each wire and its
shield. An indication of infinity
means a good wire; any indica-
tion of less than infinity means
a short-to-ground.
(3)
Replace any wire that checks bad.
b. Bad transducer
Use the multimeter set on ohms to
ground connections.
check between Transceiver TB1-9,
chassis and conduit. Check between
TB1-4 and receive transducer (blue
dot) blue lead. If any of these indi-
cations are not 0 ohms, check the
wire connection at the terminal strip,
conduit connections, and PC board
connections to the chassis. Ensure
that all transducer leads are making
good mechanical connections.
