The Power of One '"

Figure E-4 shows the interconnect wiring diagram
for connecting the ATS to the CCM-T. Refer to the
notes on these drawings.

The transfer switch presents a
shock hazard that can cause severe personal
injury or death unless all AC power is removed.
Disconnect both the Normal and the Emergency
power sources from the transfer switch. Be sure
to move the generator set operation selector
switch to Stop, disconnect the battery charger,
disconnect the starting battery (negative [-I
lead first), and disconnect AC line power before
beginning the installation.

~AWARNING I Ignition of explosive battery gases
can cause severe personal injury. Do not smoke
or cause any spark or flame while servicing bat-

b-1 Always disconnect a battery char-
ger from its AC source before disconnecting the
battery cables. Otherwise, disconnecting the
cables can result in voltage spikes high enough
to damage the DC wntrol circuits of the genera-
tor set.

Disconnect both the Normal and the Emergen-
cy power sources from the transfer switch.

If a generator set provides Emergency power,
make sure that the generator set cannot be
started by moving the selector switch to Stop.
The selector switch is located on the generator
set control panel on two-wire start systems and
inside the transfer switch cabinet door on
three-wire start systems. If there is an external
battery charger, disconnect it from its AC power
source. Then disconnect the set starting bat-
tery(ies) (negative [-] lead first).

Remove the accessory panel cover on the
back of the cabinet door.

Refer to the interconnect wiring diagrams (Fig-
ure E-4). Note that sheet 1 of Figure E-4 is for
switches without meters and sheet 2 of Figure
E-4 is for switches with meters. Locate the wir-
ing termination points inside the transfer
switch. Identify which installed options are
available for monitoring and control.

Refer to the outline drawing provided with the
transfer switch to locate and make knockouts
for the wire routing to the CCM-T. Plan the wire
routing so the monitor and control leads from

the CCM-T follow the existing harness leads.
Provide adequate wire protection at the knock-
out. Follow standard wiring practices. Wiring
must meet all applicable codes.

6. Observe minimum wire gauge requirements
for CT, monitor and control wiring. Connect the
monitor and control wires to the locations
shown in sheets 1 and 2 of Figure E-4. Provide
enough wire so that the leads can be secured
to the existing harness.

The CT wiring shown in sheet 1 of Figure E-4 is
for transfer switches that do not have meters. If
monitoring features require CTs (i.e. current,
power factor, etc.), a separate CT kit is re-
quired. See Table 17-1.

7. Set the Temperature Input switches (see Fig-
ure 17-1) to either "EXH" (80-390 ohm exhaust
temperature RTD) or "OIL.H20 (500-2200
ohm oillwater temperature RTD). Descriptions
of the CCM-T switches are included in Table

8. If the CCM-T is terminated, the termination
switch S1 must be set (see Figure 17-1). This is
accomplished by moving it to the ON or TERM

NOTE: For free toooloav, onlv one device on
each segment must be?&min&ed. The device
terminator switch can be used for this type of
termination. Multidrop bus topology requires
termination at each end of the bus using multi-
drop bus terminators (Onan PIN 300-5729).

9. Position and secure the accessory panel cover.

10. Close and lock the cabinet door.

11. Connect the data wire to the CCM-T and pro-
vide an adequate length of twisted pair wire for
future connection to a junction box or other net-
work module. Tighten the tamperproof control
box mounting screws securely to prevent tam-

12. Connect the normal AC power source, connect
the generator set starting battery(ies) (nega-
tive [-I lead last), and return the generator set
control switch to the Remote position. Connect
the battery charger, if applicable.

13. The CCM-T is now ready for network wiring.
Network wiring must be done by a trained net-
work installer. Refer to thesection 2 for instruc-
tions on network and power wiring the CCM-T
and for installation and connection of this mod-
ule to the network.

Self-installation guidelines and information on how
to self-install a network is included in Section 3.


This procedure can be used to logically install the
CCM-T when the following requirements are met.

Self-installation is limited to one PowerCommand
ATS or CCM-T, one PowerCommand Genset or
CCM-G, and no more than four annunciators and five
DIMs. The CCM-T can autobind to a genset and be
autobound by up to two annunciators and two DIMs,
but by no more than a total of three annunciators and

With networks containing a genset, the transfer
switch CCM-T must be logically installed after the
genset is logically installed and before the annun-
ciator(~) and DIMS are logically installed.

If these requirements are not met, the system must
be installed with LonMaker". Refer to "LonMaker
Installation" on 17-8.

Node Address

Each node on a self-installed network must have a
unique address. Switches 1 through 4 of switch 54
are used to set the Node Address (see Figure 17-4).
The default node address is 0010, which is a "STA-
TUS" LED pulse rate of 2.

The switches are oriented so that switch S4-1 is the
most significant bit (MSB) of the Node Address.
Thus, S4-1 has avalue of "8" when it is ON. S4-2 has
a value of 4, S4-3 has a value of 2, and 54-4 has a
value of 1. For example, to set the Node Address to
9, set switch 54 to 1001 (8+0+0+1=9). See Table

Be sure to assign each node in the network a unique

After the device has been physically installed, the
Node Address can be verified by counting the num-
ber of pulses of the "STATUS LED (DS4). See Fig-
ure 17-4. Make sure each device has a unique node



OFF I OFF I OFF I ON 1 0001 I 1
OFF I OFF I ON I OFF 1 0010 1 2

After the ATS is physically connected to the genset,
the CCM-T is ready to be logically connected to the
genset. Logically connecting to another device is
referred to as binding. Binding may be done at any
time once all nodes are installed, connected, and


NOTE: The genset and ATS must be FT-10 devices
which are able to self-install in the network. Each
device on the network must have a unique address.
