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
X
(Fig. 155-4)
or secondary
Y
(Fig. 155-2)
encoder axis. The third unlabeled receptacle
(Fig. 155-3)
contains no
encoder wiring.
TIP:
Cables may be plugged into any 8-pin receptacle. This only affects which encoder
signal is transmitted to the umbilical’s 10-pin encoder output connector plug.
The red button
(Fig. 155-5)
located on the umbilical provides an
emergency off button to the entire system. When pressed, all
power to the
NAVIC
system will disengage.
To restore system power, it is necessary to press
the green power button located on the power supply
(see “Power Supply” on page 68).
NOTE:
Terminating system power may cause the crawler to freewheel down when
operating in a vertical orientation.
All modules connect using the
umbilical.
►
The power supply connects to
the 12-pin bayonet
(Fig. 157-2)
using the power cable.
►
The user instrument is
connected to the 10-pin Lemo
®
(Fig. 157-3)
using the encoder
cable.
►
The controller is connected via
the controller cable to one of
the 4-pin receptacles on either
the user umbilical breakout
(Fig. 157-1)
or the crawler
