S5, S6, S7, Network Address Switches:
Set the three-digit HNET network address
for the NIC-C using the three rotary dial address switches located near the bottom of
the front panel. (Refer to Figure 1 for the location of the switches.) The address for
the NIC-C must be the same as the address selected for it in the Zeus Programming
Tool. To set the address, turn the pointers on each of the three dials to the numbers
for the selected address. For example, if the address is 123, set the pointer for the
HUNDREDS dial to “1”, set the pointer for the TENS dial to “2”, and set the pointer for
the ONES dial to “3”. The range of allowable addresses is from 001 to 251 (leading
zeros must be used).
WIRING
Remove all system power before installation, first battery then AC. (To power up,
connect the AC first, then the battery.)
All HNET/XNET field wiring to the NIC-C is connected to the terminal blocks of the
CC-5 card cage slot in which it is installed.
The CAN bus is connected internally to the CC-5 backplane. For CAN modules
located on the inner door inside the same enclosure as the NIC-C connect to P3 on
the CC-5 using cable CCL. For CAN modules located outside the enclosure connect
to TB1 on the PSC-12. See Figures 11, 12 and 13.
Internal Repeaters
The NIC-C provides an electrical repeater for each HNET/XNET pair. The diagram in
Figure 3 shows the wiring for each pair. Be sure to connect the pairs following the
proper polarity. Do not cross the A and B pairs. Removing the NIC-C from the CC-5 will
break the network. Removing power from the NIC-C does not break the network.
To Connect the HNET or XNET
1.
Loosen the screw of the terminal by turning it counterclockwise.
2.
Insert the wire into the side of the terminal block.
3.
Tighten the screw of the terminal block by turning it clockwise.
The NIC-C supports Class-B/Style 4 (DCLB) and Class-X/Style 7 (DCLC) HNET/XNET wiring.
Check the Zeus configuration for the proper network Style (refer to Figures 4 and 5).
The screw terminals can accommodate one 12 -18 AWG or two 16-18 AWG.
