DCM320B is an upgrade of DCM320A. It is a t, form, and function replacement for the DCM320A. The DCM320B
may be used as a direct replacement of the DCM320A in existing installations. The primary difference is the
DIP switch conguration method. The DCM320B provides more range and resolution of most conguration
parameters. This handy reference is a guide to help you get your system up and running quickly. Refer to the
EIM wiring diagram supplied with the actuator for detailed wiring information. The rst section of this guide will
help you get your Controlinc actuators hooked-up and set-up correctly. If you need to change conguration of
the unit, we recommend using our Windows based Conguration and Control Utility (CCU) rather than setting
conguration DIP switches shown in this guide. Setting network station address DIP switches is required.
The second section of this manual is the Modbus memory map reference to help congure your host database.
If you are using EIM Controlinc Network Master, then refer to the manual supplied with that unit for memory
maps. Section three of this manual is a brief system startup guide to help you do things in the proper order
to achieve a successful system startup. This last section also covers optional phase monitor module.
WARNING
Failure to follow instructions for proper electrical wiring, storage, setup, and maintenance may cause serious
injury, damage equipment, or void the warranty. Refer to Manual E796 for instructions on storage, electrical
hook-up, and maintenance.
Identify network topology from Figures 2 and 3 on page 5 and note the ports being used
(Ports A,B,C,D). Refer to page 23 for guidance on network planning and installation.
Step 2: Set network jumpers and switches
If network topology is parallel bus, then remove network termination and bias by turning
OFF S1 and S2 of SW4 on the DCM 320B card. Remove jumpers JP1 and JP2 on the CAM05,
if installed. Terminations must be left in the most distant unit on the network. If E>Net
is selected, all ports must be terminated. Baudrate range selection is not required
on DCM 320B but is required on CAM05. Refer to Figure 5 on page 5 for jumper and DIP
switch locations.
Step 3: Connect network wiring (Refer to page 23 for guidance)
Wire network ports selected in Step 1. Refer to Figure 4 when wiring Ports A and B on TBM
320A module. Refer to Figure 5 when wiring Ports C and D on the CAM05 module.

Step 4: Connect auxiliary I/O wiring
Refer to Figure 4 on page 6 when connecting discrete auxiliary I/O wiring. Note that
some functions must be jumpered between screw terminals if not wired to external
contacts. Analog I/O wiring is connected to the DCM 320B module as shown in Figure 5.
Step 5: Set network station address
Each node (valve actuator) on the network must have a unique station address. Locate DIP
switch SW1 on the DCM 320B card shown in Figure 5. Locate the desired station address
on pages 6 and 7. Set the DIP switches of SW1 to the corresponding pattern shown beside
the selected address. Press execute button to store address.

NOTE:
We highly recommend using EIM's Windows based Conguration and Control Utility
(CCU) to congure the actuators. CCU is available at www.emerson.com/eim or your local
Actuation Technologies distributor.
If using CCU,you may skip step 6 below.

Quick Start Guide
Step 6: Select configuration parameters
The actuator may be congured using the 5 DIP switches of SW2 and 8 DIP switches of
SW1. This is a back-up means of conguring the unit if CCU is not available. The actuator
is normally shipped with factory default settings. These settings may be changed by the
following procedure. Locate DIP switches SW1, SW2, and Setup Execute Button on the
DCM 320B module shown in Figure 5. Place the Selector Switch in the "OFF" position.
Select the feature or conguration parameter from the conguration tables in this manual.
Set the DIP switches per the corresponding switch pattern and then press the execute
button. If the conguration parameter is valid, the green (setup data good) LED will ash.
If error data is entered, the red (setup data error) LED will light until the error is corrected.
Repeat this procedure for each parameter to be revised. Return all 5 DIP switches of SW2 to
the OFF position and return the 8 DIP switches of SW1 to the network station address when
conguration is complete. With all SW2 switches OFF and the address switches set, press
the execute button to store the network address to nonvolatile conguration memory.

1.1 Setup Instructions
The DCM 320B is factory congured as specied by the customer purchase order. If eld
setup changes are required, follow setup instructions below. If unsure about setup of
a module, known factory default settings may be reloaded as shown under "Direct
Command Mode". When executed, the module loads known parameters from program
memory to EEPROM conguration memory. Default parameters are highlighted in this
manual by a box around the default or the value is listed
1.2 Entering Setup Mode
Locate DIP switches SW1, SW2, Setup Execute Button and LED indicators on the DCM
320B (See Figure 5 on page 5). SW2 switches select mode and SW1 switches select
setup parameters and network station address.
1) Record network station address of SW1. These switches must be returned to the
same setting before exiting setup.
2) Place selector switch in the OFF position.
3) Select desired setup mode by setting SW2 as indicated on this and following
pages.
4) Verify the DCM320B has entered setup mode by a rapid ashing CPU GOOD light.

4.1 Changing Setup Parameters
The ve switches (S1 - S5) of SW2 select the parameter/mode to be congured. The eight
switches of SW1 (S1-SB) are used to select desired setup data.
1) Locate the desired setup parameter to be revised on pages 9 through 22.
2) Set the ve switches of SW2 per the switch pattern shown for desired mode.
3) Set SW1 switches as shown or refer to the switches on pages 6 and 7 for desired
value. Selected values are multiples of the stated resolution for each parameter.
4) When both SW2 and SW1 switches are set, press the execute button to store the
setup parameter to nonvolatile memory.
5) Verify the green LED (setup data good) light ashes. If an invalid enter is made, the
red LED (setup data error) light will turn on until the error is corrected.
5.1 Exiting Setup Mode
1) Tum off all ve SW2 switches.
2) Place selector switch in the OFF position.
3) Return SW1 switches to the Network Station Address recorded in Step 1 under
"Entering Setup Mode" above.
4) Press the Execute Button.
5) Verify the DCM320B has returned to the normal run mode by a slow ashing CPU
GOOD light.
