Car CAN Channel 2
(continued)
7. On the freight door interface box (or other interface box types):
a. Remove R20 and R21 from the CN Card.
b. Remove R120 from the CNA Card.
Not all freight door interface boxes use CAN node direct interfacing, some use relays con-
trolled from I/O’s located in other components of the control system.
8. With all nodes connected (and power off), measure resistance from any node in the
system between CCH and CCL to confirm the resistive load is 60 ohms +/- 3 ohms.
Hall CAN Channel 3
This section only applies to engineered (custom) jobs where CAN nodes are assigned to
the hall channel (CH:3).
Perform this procedure if a Hall CAN channel is used each time a new controller is started
up, including grouping the new controller to an already running controller.
1. Turn OFF, Lockout, and Tagout the mainline disconnect for all controllers in the group.
2. Verify the following configurations. See Figure 2 on page 4-9.
a. CPUC jumpers are ON for the first and last controller, based on the physical order
of connections in the machine room.
• HC1C = ON.
• HC1T = ON.
b. CN Card.
• R20 and R21 installed.
• JP11 = 1-2.
• JP12 = 1-2.
c. CNA Card.
• R120 installed.
HC1H/HC1L cross-connects on CON40 of the IOF Card should be installed and cross-wired
to properly verify loading for the whole group.
3. Measure the following resistances to confirm the resistive load is 60 ohms +/- 3 ohms.
a. The IOF Card between HC1H and HC1L.
b. The lobby panel interface box (or other interface box node) between HC1H and
HC1L.
