4.3.3. Umbilical
The umbilical is the backbone of the
NAVIC
system. It provides all power, network
distribution as well as encoder signal transmission. Circuitry is incorporated into
the umbilical to protect or isolate all signals. The umbilical provides separation
between the power controller and the crawler. Various umbilical lengths are
available from 5 m to 30 m
(16.4 ft to 98.4 ft)
long.
NOTE:
Before use, inspect the cable and connectors for damage.
When any damage is
evident, the cable must
NOT
be used.
Using a damaged cable may be a safety
hazard and could also put other system components at risk.
4.3.3.1 Umbilical Connections
Multiple 4-pin and 8-pin Lemo® receptacles are located on both ends of the
umbilical. Any 4-pin connector can be plugged into any 4-pin receptacle. Any
8-pin connector can be plugged into any 8-pin receptacle.
System power and network wiring are identical on each type of plug. The
only difference being, the 8-pin receptacle encoder pin wiring is unique
to either the primary

(Fig. 63)
or secondary

encoder axis. The

unlabeled receptacle
(Fig. 63)
contains no encoder
wiring.
WARNING!
FALLING OBJECT HAZARD
.
Ensure the umbilical can freely uncoil during
operation and does not become snagged. If umbilical
becomes snagged, the crawler may fall and
SEVERE INJURY
or
DEATH
could result.
