INTRODUCTION
The RC-2000 controls virtually all parameters
of commercial refrigeration by combining the
latest hardware and software available. The unit
may be networked with the ERC-1000 to add
environmental control of HVAC (heating,
ventilation, and air-conditioning), lighting, antisweat heaters, and other miscellaneous loads to the
system.
By combining refrigeration and
environmental control, Danfoss/ECI controllers
work together as an integrated system, reducing
energy and maintenance costs, and safeguarding
products and equipment. Drawing 1 below

RC-2000 HARDWARE SYSTEM OVERVIEW
The Danfoss/ECI Refrigeration Control
System contains an RC-2000 Central Processing
Unit (CPU), up to fifty-nine Distributed Control
Units (DCUs), and up to thirty-two Serial Input/
Output Modules. The RC-2000 unit may be wallmounted or rack-mounted.
The RC-2000 CPU is assembled from a sturdy
enclosure, housing these components:
• Power supply
• Twenty-line by forty-character (20 x 40)
backlit liquid crystal display
• Keypad
• CPU Board
Display And Rubber Keypad
The display and rubber keypad are found on
the RC-2000 door; they provide a graphic means of
firmware communication (see Drawing 2 below).
The 20-line by 40-character backlit liquid crystal
screen display is powered from the CPU Board
supply. Each screen provides clear menu choices
that you can respond to via the number and arrow
keys on the keypad. For more detail on the menu
screens and programming capabilities of the RC2000 system, refer to the RC-2000 Refrigeration Control
Operations and Programming Manual, Form #
4464402800, shipped with this product.

Power Supply
RC-2000 Battery Backup
The battery backup for the RC-2000 is found
on the Power Supply Board in the enclosure. Refer
to Drawing 3 below for a detailed illustration of the
RC-2000 Power Supply and its components.
CAUTION
USE a DEDICATED POWER SOURCE to
power the RC-2000 whenever possible.
FAILURE TO DO SO may cause
EQUIPMENT DAMAGE.
Danfoss/ECI ships the battery upside down
and disconnected from the circuit. It is a standard
9V alkaline battery.
RC-2000 power specifications are listed below.
Refer to Drawing 3 for a detailed illustration of the
power supply and its components.
IMPORTANT
The battery should remain in the upside-down
position until the unit is field started. DO NOT
ACTIVATE the battery until the unit is field
installed. Since all setpoint data is stored in
non-volatile memory, the battery is not needed
for memory backup.
AC Input....................... internally fused at 1A
Voltage.......................... 115 or 230VAC
Power............................ 50 or 60Hz
Operating Voltages ....... sent to CPU Board via
ribbon cable
Voltages Supplied ......... +5VDC, +9VDC,
+12VDC, -24VDC
+9VDC battery backup
Battery Voltage ............. CPU informed when low
NOTE
This BATTERY backs up the time of day clock
and logged information ONLY.
NOTE
Danfoss/ECI recommends use of transient and
surge protection.
The FLASH EPROM backs up all setpoint
data.The setpoint data backed up in FLASH
EPROM is secure through a power loss.
When the RC-2000 system is in operation, the
three red LEDs should always be lit.

CPU Board
CPU Board LEDs
The CPU Board includes three sets of LEDs to
display communication status (see Drawing 4
below).
A list of CPU Board features appears below:
V40 Microprocessor............ 10 MHz operation
Addressing capability.......... 1 MB memory
RAM.................................... 512 kilobytes (KB)
Flash EPROM ..................... 2 or 4 MB
The Serial LEDs are labeled Serial RX and
Serial TX on the CPU Board. They are located in
the upper right corner to the left side of the 12VAC
termination connection. They flash continuously
to show satisfactory serial communication with
the RC-2000. Serial LEDs that do not flash
continuously indicate a serial communication
problem. Refer to the Serial Communication
Troubleshooting section of this manual for more
information if you encounter a non-flashing LED.
In addition, the CPU Board contains a
watchdog timer circuit for processor lockup
recovery, an eight position ID dip switch, 2 serial
communication LEDs to display serial communication status, 1 LON communication LED to
display DCU status, and 2 communication LEDs to
display remote communication status. Refer to
Drawing 4 below for a detailed illustration of the
CPU Board and its features.
The LON LED is labeled LON on the CPU
Board. It is located toward the right side of the
board, just under the 12VAC termination
connection. This LED blinks rapidly when the
MIP daughter board is installed and functioning
correctly. (This information pertains to systems
that have an MIP daughter board installed for
Echelon communications.)
CPU Board Serial Ports
The CPU Board contains the following serial
communication terminals and ports (see Drawing 4
below).
1. Serial terminal to I/O
2. RC-2000 RS485 terminal (3 pin)
3. Modem RS232 port
4. 1000 Series RS232 port
5. AUX RS232 port
6. The LON port (MIP Daughter Board)
The Communication LEDs are labeled
COMM RX and COMM TX on the CPU Board.
They are located to the center right side of the
board. The Communication LEDs blink only when
using remote communication or if the unit is
dialing out. If you experience problems with RC2000 remote communications, refer to the Troubleshooting Guide in this manual for troubleshooting
information.
NOTE
The LON port is supplied on a removable
daughter board. (This daughter board contains
the MIP chip, which operates the program to
communicate from the V40 processor to the
DCU units.)

RC-2000 CPU COMMUNICATION
CPU Communication Terminals
and Ports
Serial Terminal
Use the Serial terminal to connect the Serial
Input/Output Modules to the RC-2000. This
terminal is on the top right half of the CPU Board.
It is silk-screen labeled “Ser Out.” Make the
connection with a pair of non-shielded wires that
are polarity sensitive (use Belden wire #8461, 2
wire, #18 unshielded twisted pair). Start the loop
at the RC-2000; proceed to all the Serial Input/
Output modules in a daisy chain configuration.
See Drawing 6 on the following page and Figure 5
in Appendix D for a detailed diagram of this
terminal and the CPU Board.
NOTE
Serial Input/Output modules that are remote
mounted greater than 50 feet must have local

IMPORTANT
Termination resistors must be used on the first
and last RC-2000 in the loop.
Configure the termination resistors with jumpers
JP2 and JP3 on the CPU Board.
Remove jumpers JP2 and JP3 for those units in
the middle of the loop.
Install the jumpers on the first and last units in
the loop.
Modem RS232 Port and Series 2000 to
1000 RS232 Port
The Modem port or the Series 2000 to 1000
port connects the modem to the RC-2000. To
make this connection, you need special adapters
and phone cable wiring. This port communicates
to the RC-1000 via the RJ-11 plug (modem 6-Pin
phone jack) and is located on the bottom right half
of the CPU Board. It is silk-screen labeled.
RC-2000 RS485 Terminal (3 Pin)
The RC-2000 RS485 terminal provides RC2000 to RC-2000 communications. Make this
connection with a pair of polarity sensitive,
shielded wires (use Belden wire #8760, 2 wire, #18
shielded twisted pair).
The terminal is located on the middle of the

Making Modem To RC-2000
Cables
cable tester from Danfoss/ECI (Part # CC/
60028400).
To communicate between the RC-2000 and a
modem, use a standard six-conductor
communication cable with a modular RJ-11 jack on
both ends. The cable must be assembled with the
jacks crimped the same way on both ends. With
the tab facing towards you, install cable with the
“white conductor on the right” for both ends. See
Drawing 7 below for details.
NOTE
Danfoss/ECI-manufactured cables apply the
White on Right Rule. They are assembled with
the white wire on the right side of the connector.
If one end needs to be shortened, make sure the
proper connector orientation is maintained.
If the ends of the cable being tested can’t
physically be plugged into the same tester, then
two testers are needed to perform the test.
To make custom cable lengths or repair a
cable, you need a cable termination tool. This tool
(Part # CC/CRIMP-1) and RJ-11 connectors (Part
# CC/PCONN) are available from Danfoss/ECI.

SERIAL HARDWARE AND HOOKUP
Introduction
Serial describes the data transfer method from
I/O devices to the RC-2000. A non-shielded two
wire serial connection made between the modules
leads back to the RC-2000, and a ‘Data Bit Stream’
transfers the information through them (i.e., the
digital signals follow each other much like a train
of information). This type of information transfer
requires a two-wire connection.
Serial Input/ Output Module
Power Requirements
All Danfoss/ECI serial boards require a
12VAC power source. Danfoss/ECI’s TF-6
transformer has a dual voltage, 120 or 230VAC
primary with a 12VAC, 56VA secondary output for
serial I/O power. The 56VA rating should not be
surpassed as per Table 4 below. Make all 12VAC
connections on the I/O boards as per the drawings
in the sections ahead. All connections should be
daisy chained through the 12VAC In and 12VAC
Out connections on each I/O board. Refer to
Table 4 below for voltage information. Refer to
Drawing 10 and Drawing 11 on the following page
or Figure 6 in Appendix D for TF-6 and TF-16
transformer configuration.
NOTE
12VAC power cannot EXCEED a distance of 50
feet for the Serial Relay Boards or 100 feet for
the Serial Modules.

equation:
(# of each component) x (multiplier) = System Current Draw (for that
component)
2. Next, add together all of the system component current draw results to determine the
total System Amp draw.

Serial Communication
RC-2000 CPU Serial Connection
The CPU Board serial communications circuit
is optically isolated and requires 12VAC power.
Bring the power from one of the serial modules to
the CPU Board serial terminal labeled “12VAC.”
(see Drawing 12 below.) See Table 5 below for
appropriate communication wire size and
length.
Serial communication originates at the RC2000 CPU and is supplied via a two-wire, 18 awg,
unshielded, twisted pair wire. Table 5 shows the
wire size and length to use.
Each serial connection is done through the
designated terminal strip on each particular board
(see the drawings in the sections ahead).
Designated termination points are silk-screen
labeled. There is generally an “in” for the signal
into the board, and an “out” to continue the signal
to the other boards in the system. An arrow marks
a “common” termination point, because this is a
polarity sensitive circuit. If the termination
connector is removed from a particular board, the
continuity between the in and out signals becomes
an open circuit.
Two serial status LEDs are located to the left
side of the board, above the 12VAC termination
connection. They are labeled Serial RX and Serial
TX (see Drawing 12 below). A continuous
flashing light indicates satisfactory communication
with the RC-2000. A non-flashing light indicates a
problem in the communication status. Refer to the
Serial Module Troubleshooting section of this
manual for more information if you encounter a
non-flashing LED.
NOTE
With 12VAC power, the maximum distance is
50 feet. Distances greater than 50 feet require a
local power supply.

16 Channel Universal System
Capability
The system has evolved with the capability to
use a universal input 16 channel board (SUI16). If
the SUI16 is added to the system, it replaces the
capability to support the Serial Analog Input 8
Channel Module (SAI8) and the Serial Digital
Input 8 Channel Module (SDI8) of the same board
address. The SUI16 offers increased system
capability because of the independent flexibility of
each channel.

Power Connections
Indicator Lights
This board (SR8 Relay board) requires a
12VAC power supply and draws approximately
0.5A. Power connection IS NOT polarity
sensitive and is done through a 12VAC connector
at the top right corner of the board. This
connection is marked on the silk-screen labeling on
the board. Refer to Drawing 14 on the previous
page for a diagram of the relay board.
Three LEDs are located on the right center
portion of the board:
NOTE
A power LED is located directly below the
12VAC connector. It lights when 12VAC power
is applied to the board.
Communication Connections
The serial communication IS polarity
sensitive and is connected through the RS232
connection at the bottom right corner of the board.
The silk-screen label on the board designates the
polarity of the connections. The signal should
connect at the ‘In’ and the common should connect
at the ‘common.’ Once the connection is complete
and the board is assigned one time to the program,
the two LEDs below the power LED light to show
satisfactory communications (this applies only if
the relay board has been assigned in Version 4 and
above of the RC-2000).
CAUTION
Observe the POLARITY of the SERIAL
CONNECTIONS when installing. Incorrect
polarity of serial connections causes an
inaccurate reading or no reading at all.
DO NOT USE the RS485 connection located
directly above the Serial RS232 connection on
the right side of the board. The connection is
for future use.

Transmit
The top LED labeled ‘Power On’ indicates
satisfactory application of the 12VAC when it stays
lit. The middle LED labeled ‘Receive’ indicates
satisfactory serial communications when it blinks
quickly, almost appearing continuously lit. The
bottom LED labeled ‘Transmit’ also indicates
satisfactory serial communications when it blinks
at a steady rate.
Output Control Connections
Removable terminals are provided for
common (C), normally open (NO), and normally
closed (NC) relay operations. All relays are fused
at three amps, 250VAC and 1/3 hp at 240VAC.
Refer to Drawing 14 on the previous page for a
detailed location of the output terminal
connections.
Switches
Each relay has a three-position control switch
and is marked as follows:
•
•
•
ENRGZ (Energized)
AUTO (Automatic)
DNRGZ (De-energized)
When the ENRGZ or DNRGZ switch is on, the
operational status of the relay bypasses the
computer. When the system runs in AUTO, the
RC-2000 runs the system.
If you desire manual control of your system,
place the control switch in override. If you desire
computer control of your system, place the control
switch to AUTO.
22
Switches (continued)
NOTE
The positions ENRGZ and DNRGZ override the
RC-2000’s control of the relay’s state.
If the red LED is lit, the RC-2000 or the
“ENRGZ” override energizes the relay.
If the red LED is not lit, the RC-2000 or
“DNRGZ” switch de-energizes the relay.
If the blinking yellow LED is lit, the control
switch is moved from the “AUTO” position to
either of the two override positions.
In the event of a system failure, the relays fail in
the DNRGZ position.
SAFEGUARD
Label all relays with their correct function—this
assists any future troubleshooting or
maintenance procedures.

Channel Type Setup
The SUI16 in this universal mode enables each
channel to be set up as a different type. The
channel setup is done with a combination of
hardware and jumper configurations and RC-2000
software. Each channel has two jumpers that need
to be set to indicate the desired channel type prior
to software setup via the RC-2000. Please see
Drawing 22 or the silk-screen on SUI16 boards
Rev. 5 or higher for jumper position reference.
NOTE
For this channel type setup, you must use the
RC-2000 Version 4.00 or higher. For software
setup, see the RC-2000 Programming Manual.
Eight channel mode jumpers JX, JY, J1 and J2
need to be removed in Universal 16 mode
[Refer to Drawing 20 (the Rev. 5 board)]. These
jumpers are located at the top right corner of the
Rev. 5 boards.

Rev. 5 Input Board Setup
Danfoss/ECI’s 16 Channel Modules must be
configured in the field per your application needs.
The setup procedure for 16 Channel Rev. 5 Input
Boards follows. You can set up the Danfoss/ECI
16 Channel Board as a 16 Channel Universal Input
Board or as a Dual Addressed 8 Channel Input
Board. The following setup procedure is for the 16
Channel Rev. 5 Board.
1. Set the dip switches for communication
ID. Refer to Drawing 21 for an example of
these settings.
NOTE
This is a binary setting.
Set switches 5-8 to the “ON” position for 16
Channel Mode.
2. Remove the four 8 Channel Jumpers from
the top right corner of the board.
NOTE
These jumpers are:
J1, J2, JX, JY
3. Terminate all serial wiring at the bottom
right corner labeled “Serial.” Ensure
correct polarity. Terminate the common
wire into the connection labeled “COM.”
4. Terminate 12VAC power at the bottom
right corner labeled “12VAC.”
NOTE
Make sure that the voltage wiring is paired in
either the “In” or “Out” position (NOT
POLARITY SENSITIVE).
5. Set each input with two jumpers.
NOTE
Channel Number labels are below the
appropriate Jumpers 1-16, from left to right.
32
6. Set the jumpers according to their silkscreen label (found above the jumper) as
per their channel type. Refer to
Drawing 22 on the previous page for an
example of the board’s silk-screen labels.
7. Terminate the sensors at the terminal strip
at the bottom of the board. Terminate the
input signal at the channel number and the
common at the “COM.”
NOTE
There is not a common connection for each
signal input. All common terminals are
connected together for use with any channel.
8. Attach the positive load to the terminal
strip labeled +12V UNREG at the bottom
center of the board for any sensor requiring
12V power (e.g., pressure transducer, etc.).
9. Remove 12VAC for approximately 15
seconds after all channel jumpers are set
and reconnect the power.
10. Assign the board number to the RC-2000
(Version 4.0 or higher). The red LED
serial light blinks.
NOTE
The red LED serial light does not blink until the
board number is assigned into the RC-2000
(Version 4.0 or higher).
Dual 8 Mode Operation
The SUI16 board has another mode of
operation referred to as Dual 8. This mode is
supported because it operates with older versions
of the RC-2000 (firmware versions prior to 4.00).
This mode sets the board as two separate eight
channel groups on one SUI16 board. Each group
accepts only one type of input (i.e., digital, TP-1,
1-6V, etc.). In this mode, the SUI16 operates
similarly to two eight channel input modules.
NOTE
In the Dual 8 Mode, the RC-2000 system
supports the following:
•
•
four SUI16 boards set up as groups of
analog inputs, and
four SUI16 boards set up as groups of
digital inputs.
The input types for Dual 8 channel mode can
be as follows:
•
•
•
•
•
1-6 Volt (pressure)
TP-1L
TP-1H (group 2 only)
0-10 Volt (group 1 only)
Digital Input
NOTE
The numbers on the dip switch are not the
binary value of the switches. Refer to
Drawing 23 for the physical position of the
switches per each group address.
An SUI16 board in Dual 8 mode is actually
addressed as two 8 channel boards in the RC2000 system.
The serial LED (D103) double blinks. This
double blink indicates satisfactory PSI
communication to each group on the board.

Board Address Setup
In Dual 8 channel mode, the channels cannot
be configured on a per channel basis, but must be
configured as groups of eight, each of the same
type of input. The board type setup in this mode is
done through hardware and jumper configuration.
Please refer to Drawing 20-Sixteen Channel
Universal Input Board (Rev. 5-7) and Drawing 23
and 24 for dip switch settings and jumper configurations.
The SUI16 board in Dual 8 mode is addressed
with two separate IDs. The switches represent
binary values. Switches 1-4 are used to address
Dual 8 group one (channels 1-8). Switches 5-8 are
used to address Dual 8 group two (channels 9-16).
Address the groups via a binary-code dip switch
setting. The sum of the switch values that are set to
on designates the board address (1-4, group one;
and 5-8, group two). Refer to Table 11 for the
binary values of the switches.

Board/ Channel Type Setup
Channel Jumpers
The SUI16 board in this Dual 8 mode requires
that each group is set up with the same channel
type within the group. The setup is done with a
combination of hardware jumper configuration and
RC-2000 software.
Each channel has two jumpers that need to be
set to indicate the desired channel type. Each
channel in a group (group one, channels 1-8; and
group two, channels 9-16) needs to be set to the
same input type. The common channel type of
each group also needs to match the eight channel
mode jumpers setting for that group. Please see
Drawing 24 or the silk-screen on your Rev. 5 or
higher board for correct jumper settings.
8 Channel Mode Jumper
Each group has a pair of 8 channel jumpers.
Refer to Drawing 24 below for their location.
These jumpers set up the input type of each group
on the SUI16 board. Set J1 and J2 for group one
(channels 1-8), and JX and JY for group two
(channels 9-16). Drawing 24 illustrates the correct
jumper setting positions.
IMPORTANT
The SUI16 board in Dual 8 mode ACCEPTS
0-10V input type on GROUP ONE, channels
1-8 ONLY.
The SUI16 board in Dual 8 mode ACCEPTS
TP-1H input type on group two, channels 9-16

RC-2000 Power Monitoring
Watt Transducers
Power System Environments
The RC-2000 uses a watt transducer (a
monitoring device) to monitor power usage. The
watt transducer “deduces” instantaneous power
usage, and sends a proportional signal to your
energy management equipment (i.e., your RC-2000
Controller).
The two most common power systems found
in a supermarket environment are a 208V/120V
system or a 480V/277V system.
The watt transducer works (i.e., determines
watts) by measuring current inputs from current
transformers (CTs), and by sensing voltage
readings directly via its internal circuitry. CT input
signals must range from 0 to 5 amps AC on
Danfoss/ECI transducers. The voltage is
application and transducer specific. The output
signal to the RC-2000 is from 0 to 10VDC.
The RC-2000 generates a kW reading by
comparing the input signal to the software
configuration scale factor.
For example:
If the scale factor is 1000 and the input reading is
5VDC, the kW reading displays as 500 kW.
IMPORTANT
The scale factor equals the maximum kW. Refer
to Table 27 in Appendix C for CT scale factor
values.
In the 208V/120V system, 208V is the phaseto-phase voltage and 120V is the phase-to-neutral.
In the 480V/277V system, 480V is the phase-tophase voltage, and 277V is the phase-to-neutral
voltage.
Depending on the application of power
monitoring, each watt transducer can have a
different number of elements. The number of
elements required is dependent on your
application. Each element in a transducer requires
the following inputs for a correct output:
•
•
One CT input
One voltage measurement input
The two types of power systems used with
Danfoss/ECI applications are three-phase, fourwire systems, and three-phase, three-wire systems.
Three-Phase, Four-Wire Systems
(House Power Monitoring)
This system is generally used to monitor house
power in conjunction with Danfoss/ECI’s HVAC/
TOD controls (e.g., EC-1000). Four wires
typically come into a building (three phases and
one neutral). This system is referred to as a 3phase, 4-wire system.
This type of system monitors loads that vary
from phase to phase. This application uses three
CTs to accurately sum the current usage. In
addition, at least two voltage measurements are
required (phase to neutral). This type of power
monitoring requires a 2½ element transducer.
A third voltage measurement (i.e., a three
element transducer) is only required on systems
that have unbalanced voltage on each leg.
Danfoss/ECI recommends a 2½ element transducer
in this situation.
38
Three-Phase, Three-Wire Systems
(Rack Power Monitoring)
Three wires usually come into a typical
refrigeration rack. The neutral is not required;
hence the term 3-phase, 3-wire system.
A 3-phase, 3-wire system requires only two
CTs because the third phase can be considered the
return and therefore the sum of the other two. This
type of power monitoring requires a two element
transducer, which requires two phase-to-phase
inputs.
Current Transformers
A current transformer senses the high amount
of current running through a primary electrical
conductor and transforms the reading into an
isolated low current signal that is read by a watt
transducer. The ratio of a CT refers to the dividing
factor associated with it. Danfoss/ECI supplies a
wide range of CTs for different amp requirements.
All Danfoss/ECI CTs have a standard five amp
output ratio factor.
CAUTION
To avoid a POTENTIAL EXPLOSION if
power is not shut down:
ALWAYS short the output signal wires of the
CT to each other before installation or service of
the CT or watt transducer.
If power is not shut down, the CT strives to
output the current ratio as described above.
Eventually, it will break down the insulation or
air between the terminals.
EXPLOSION MAY OCCUR!
The following pages make connection
references to each Danfoss/ECI Watt
Transducer. Ensure that the connection
diagram matches the model number of the watt
transducer. If you have questions, contact a
Danfoss/ECI representative.
IMPROPER INSTALLATION CAN
RESULT IN SERIOUS INJURY!
For example:
A 1600:5 CT puts out 5 amps when it senses a
1600 amp current through its field.
Two types of CTs are available:
1. Split core CTs can be taken apart and
reassembled around the bus bar or cable.
2. Toroidal CTs must be slipped over the
conductor before cable termination. You
cannot take them apart.
Danfoss/ECI Watt Transducers
Danfoss/ECI has introduced new kW watt
transducers. They differ from the previous models
in this way: they produce a true 0-10VDC output,
so they DO NOT need a 22K ohm resistor installed
across the output to the 0-10VDC. The new part
numbers are cross referenced with the previous
part numbers in the chart below.
NOTICE
The previous part numbers are now obsolete and
the new ones serve as direct replacements.

ECHELON®1 INTEROPERABILITY
Echelon Interface with the
Danfoss Inverter
The RC-2000 Version 4.10 and higher
incorporates an Echelon Interface with the Danfoss
Inverter. This feature eliminates the need for
several analog and digital connections between
these two devices. This information is transferred
via the Echelon network (16 gauge non-shielded
twisted pair Belden #8471).
When configuring in this mode, the following
connections are required between the Danfoss
Inverter and the RC-2000:
Echelon

Hardware Requirements
The Danfoss Inverter needs to be equipped
with an Echelon Option card. Please refer to your
Danfoss manual for further information. For a
detailed connection diagram, please refer to Figure
20 in Appendix D.
The RC-2000 requires a “new-style” CPU
(part # 5120001400) equipped with an MIP
daughter board. The firmware must be level 4.10
or higher. The network wiring follows the Echelon
network termination rules for an FTT-10
transceiver (free-topology). The Danfoss Inverter
has a switch on the option card for network
termination. These switches should be set
according to the Echelon termination guidelines
(on is up, and off is down).
When configuring for this mode, DO NOT

Switchover Relay
Control relay for compressor
(has an auxiliary connection
for the start command to the
inverter)
The interface still requires a hardware
connection for the start command to the inverter.
Make this connection with a series circuit through
the auxiliary contact on the variable speed
compressor contactor (Danfoss/ECI control relay
for the inverter) and the switchover relay. The
condenser fans should have a hardware start wired
in series through the Danfoss/ECI inverter control
relay and the switchover relay. The condenser fans
should have a hardware start wired in series
through the Danfoss/ECI inverter control relay and
the switchover relay.
The Danfoss Inverter is set to require a
hardware and a software start to run forward. By
placing the switchover relay in override, the
interface is able to be placed in hard override. If
the switchover relay is placed in hard override, the
RC-2000 recognizes the override condition and
does not transmit control word via the Echelon
Network.

Software Requirements
This interface has many similarities to the case
control interface being done via the Echelon
Network. Each Danfoss Inverter is assigned a
node address number for network identification.
This node address number can be the same number
as one that is used for case controls or other
devices because each device type resides on an
individual subnet.
IMPORTANT
Danfoss Inverters connected to the same RC2000 should not be assigned duplicate node
addresses.
4. After you assign the inverter address, you
have only two more setpoints to assign:
the control relay, and the switchover relay.
Assign them now to fit the individual
application.
5. Next, bind with or node address the device
via the main menu. Press [8 LON
Network]. The screen looks like this:
LON NETWORK
Device Type:
Select Action:
Start Node ID:
Set the software interface as follows:
1. Configure the variable speed option in the
Rack Configuration Screen as done in
previous versions. You may select
condensers, compressors, or both, as
needed for your application.
2. Select the polarity of the switchover relay
(if you are using it in the application) in the
rack configuration screen.
IMPORTANT
If the POLARITY is set IMPROPERLY, the
Danfoss Inverter does NOT RECEIVE the
START COMMAND and the interface
FUNCTIONS INCORRECTLY!
3. You should only assign the inverter
address to a setpoint in the variable speed
section of the rack setpoint screen when
you are using the ECHELON DANFOSS
INTERFACE. This setpoint renders some
setpoints unnecessary; they display as
N/A. Actual control of the device per
these setpoint assignments occurs when
the binding process is completed; however
they can be assigned before then.
IMPORTANT
Danfoss/ECI recommends setting the inverter
address setpoint assignments at: 01, 02, 03, etc.;
these assignments are dependent on the number
of inverters being controlled.

This prompts user that

Once you set the LON NETWORK screen,
you need to toggle the service pin switch
(SW2) on the Danfoss Echelon Option
Card. (The switch is set in the normal or
up position. Move it to the down position,
and then back to normal.) Once the node
address is successfully installed, the
current node status line clears and the
controller is ready for the next address.
6. Once the node address is complete, the
Danfoss Inverter is on-line and ready to be
controlled. At this point, the frequency
and current displays at the RC-2000 Rack
Status screen are live status.
Safety Considerations and Settings
You should be aware of the following settings
in order to benefit from the safety or switchover
benefits of the interface:
1. When the binding process is complete, the
Danfoss Inverter is set for a THREEMINUTE MAXIMUM receive time.
The inverter defaults to a predetermined
state if no messages are sent to it from the
RC-2000 within this three-minute time
interval.
Set this predetermined state on Parameter
824 TIME-OUT F in the Danfoss
Inverter. Danfoss/ECI recommends
MAXIMUM as the setting, because it
defaults the inverter to a 100% run if
communication is terminated.
2. If a technician needs to service the system,
or if software upgrades require extensive
code downloads to case controls, the
SWITCHOVER RELAY should be placed
into OVERRIDE until the work is
finished. Once the switchover relay is
placed in override, communication to the
inverter stops. The inverter receives a stop
command via hardware and the variable
speed compressor cycles at a fixed
capacity (on/off).
3. The Danfoss Inverter can be configured for
software or hardware start/stop commands.
The present interface requires that
Parameter 506 START be set to “AND.”
By setting this parameter to “AND” the
inverter requires a software and hardware
start prior to a RUN condition. This
ensures that an override can always be
accomplished when you put an Danfoss/
ECI control point in hardware or software
override.
4. This interface doesn’t use a reset relay.
The inverter has its own reset function that
attempts a reset prior to sending a fault
condition to the RC-2000. Once a fault
condition is recognized, the RC-2000
immediately goes to a switchover state (No
Delay) and the fault is entered into the
alarm log. Once the fault is entered into
the alarm log, the inverter does not receive
transmissions until the fault condition is
reset manually.
5. This interface is a communication
protocol. Therefore, Danfoss/ECI
recommends that a boolean statement be
installed into the RC-2000 for fail-safe
back up. This statement should reference
the operating pressures and, if they exceed
safe ranges, the switchover should be shut
down, and an alarm should be generated.
Refer to the RC-2000 Programming
manual, or contact your Danfoss/ECI
representative for further details.
NOTE
When OPERATING a split suction group rack
with a common condenser, BE AWARE that
HIGH PRESSURE CONDENSER
SAFETIES need to be INSTALLED for
BOTH SUCTION GROUPS.

Echelon Interface with the Encore
ESC-200 Bitzer Screw
Compressor Module
The RC-2000 Version 4.10 and higher
incorporates an Echelon interface with the Encore
ESC-200 Bitzer Screw Compressor Module.
Alarm status information is sent to the RC-2000
via the Echelon Network (16 gauge, non-shielded
twisted pair, Belden # 8471).
Each Bitzer Screw Compressor has an
individual ESC-200 module assigned for control,
alarm safeties, and long-term alarm logging. This
interface allows each individual ESC-200 module
to send any alarm status to the RC-2000 when it
occurs, and to send an OK when the alarm clears.
The RC-2000 recognizes the compressor number
(as assigned to the RC-2000) and the alarm type.
The information is logged and dial outs occur, as
required by the application.
This interface eliminates the need for several
interposing relays that were previously required to
signal different alarm conditions. It also adds the
ability to recognize individual alarm types on
individual compressors and to reset the alarm
condition without requiring a visit to the site.
Hardware Requirements
The Esc-200 module needs to be equipped
with a compatible Echelon chip and transceiver.
Please refer to your Encore manuals for more
complete information.
The RC-2000 requires a “new-style” CPU
(part # 512001400) that must be equipped with an
MIP daughter board (part # CC/20056400). The
firmware must be at a 4.10 level or higher. The
network wiring follows the Echelon network
termination rules for an FTT-10 transceiver, using a
16 gauge, non-shielded, twisted pair, Belden
#8471. For a detailed connection diagram, refer to
Figure 21 in Appendix D.
46
Controller Interface
The ESC-200 uses a hardware dip switch
setting to initially set the board address. This is
marked as dip switch #2 (SW2). This switch
should be set prior to performing the install node
function.
Follow the procedures listed below and on the
following page when installing an ESC-200 on the
RC-2000 Echelon network.
1. The ESC-200 module must have a
controller address assigned to its
associated compressor. This setpoint can
be assigned in the Rack Setpoint screen
directly below the compressor relay
setpoints as follows:
Compr:
Relay:
Capacity:
Unloaders:
Ctrl Addr:
1
0-0
010
0
00
NOTE
The variable speed compressor also has a
setpoint field for a controller address to be
assigned. This requires configuring for variable
speed and entering the Setpoint Screen. The top
line of the variable speed setpoints have fields
for Invertr Addr and Ctrl Addr, in this order,
from left to right. The ESC-200 is assigned to
the Ctrl Addr as listed above.
IMPORTANT
Make certain that the number assigned to the
control address matches the switch selection
made on dip switch #2 on the ESC-200 module.
2. Set the Install Node function. This is done
from the main menu by selecting number
[8 LON NETWORK]. Set the screen as
follows:
LON NETWORK
Device type:
Select Action:
Start Node ID:
End Node ID:
Start Now?:
Current Node Status:
ESC-200
Install Node
001 (Dependent on the
desired address)
001
Yes
This prompts you that
the RC-2000 is ready
for the module to be
addressed.
3. When this is set, there is an alarm reset
button that needs to be pressed on the
ESC-200 module (SW3, located to the
right of the dip switches on the ESC-200).
The button needs to be depressed for
approximately five seconds for the node to
be installed.
There is an amber service LED “I16” located
at the bottom left corner of the ESC-200 module.
When the node is initialized, this light illuminates.
The light also blinks if the module is not
configured prior to node installation. Once this
process takes place, the Current Node Status line
on the RC-2000 clears, displaying the success of
the install process.
NOTE
The rack status screen displays a “_” below the
associated compressor unit, indicating that an
ESC-200 is assigned to that unit.
If this module is in alarm, it displays an “A” in
the above-mentioned space and enters the alarm
into the alarm log.
Alarm Status
The ESC-200 does not honor any alarm time
delays. If the module is in alarm, it is entered into
the log without delay. The RC-2000 has a dialout
capability for each of these alarms, and the alarm
relay assigned to the suction alarm deenergizes if
an ESC-200 is in alarm.
The alarms received from the ESC-200 are as
follows:
MOTOVR
OIL FLW
OIL LVL
GAS TMP
PHASE
ROTATE
RUN PRF
Motor Overload
Oil Flow
Oil Level
Discharge Gas Temp.
Phase Failure
Rotation Failure
Run Proof
For Example:
The RC-2000 logs the following “Run Proof”
alarm like this:
01-01
00:11
Rack A
C2RunPrf
It displays the date, time, and rack assignment.
The C2 represents the compressor number and the
alarm type.
This information concludes that on Jan. 1 at 12:11
a.m., Rack –A compressor #2 went off on the Run
Proof Alarm.
NOTE
The RC-2000 dials out the above information for
each alarm.
The RC-2000 logs the following as an event:
FILTER
Dirty Filter

Echelon-Equipped Kysor-Warren
Interface Control
The Kysor-Warren Interface Control (KWIC)
incorporates all relays, circuit breakers, and control
switches into one centralized output control device.
This device allows for centralized mounting of all
circuit and compressor output modules. The
KWIC assembly replaces the need for a large
portion of the control circuit installation process.
The centralized rack mount, a hallmark of the
KWIC, holds a maximum of four circuit modules
per enclosure, and reduces control panel wiring by
40 percent, thus lowering wiring application
mistakes.
The KWIC is a networked refrigeration control
device. To accomplish output control, the KWIC
chassis assembly includes an engine with
processor, a processor interface board (PIB), and a
buss board. A maximum of four control output
modules can be connected to the buss board. One
KWIC assembly controls a maximum of 16
refrigeration and defrost circuits.
The control output module includes circuit
breakers, rocker switches, relays, and status LEDs
for each controlled circuit.
See Figure 22 in Appendix D for a more
detailed description of the KWIC assembly
installation.
NOTE
Refrigeration and defrost relays on the control
output module share one circuit breaker and
rocker switch, but are designed with a hardware
interlock to ensure that both do not energize
simultaneously.
48
Dual Chassis Connection
Two KWIC Chassis Assemblies can be
connected together for increased control capability.
This connection creates a driver and expansion
assembly relationship. The driver chassis
assembly includes the engine board with processor.
The processor on the driver controls output for the
driver and expansion chassis.
IMPORTANT
The expansion assembly does not have an
engine board. The driver chassis engine board
controls output for both assemblies.
The expansion chassis receives control
instruction via the driver chassis assembly. These
driver/expansion assemblies may be linked with
other KWIC driver/expansion assemblies on an
Echelon or RS-485 network.
NOTE
Limitations of the KWIC network are specific to
the refrigeration control that manages the
interface with the KWIC assemblies.
For a complete parts description and
installation procedure for the KWIC module,
please reference the Danfoss/ECI KWIC (KysorWarren Interface Control) Installation and
Operations Manual, part # CC/4464400010.
Case Controllers
The CPM has two main functions:
Danfoss/ECI Distributed Control Unit
1. It supplies power to the DCU
motherboard.
The Danfoss/ECI Distributed Control Unit
(DCU) is a micro-controller-based unit.
Networked with the RC-2000, the DCU becomes
part of an integrated control system.
The DCU controls sensors, valves and
refrigeration at the case level. The following
valves may be in place in a DCU-controlled
system:
•
•
•
Refrigeration solenoid
Pulse-type Electronic Expansion Valve
Electronic Evaporator Pressure Regulator
(EEPR)
NOTE
Danfoss/ECI offers a version of the DCU that
contains a transformer, making it a complete
stand-alone controller.
2. It controls fans, lights, anti-sweat heaters,
and electric defrost loads.
The DCU stores application code and setpoint
data in non-volatile memory. The application code
may be downloaded from the RC-2000,
eliminating the need for EPROM changes at the
DCU.
Fully programmable, the DCU accommodates:
•
Ten universal inputs; programmable to
accept either Danfoss/ECI TP1 or TP2
temperature sensors
Or
•
•
Low-voltage, dry-contact digital inputs
4-20mA sensor inputs
NOTE
The DCU may be programmed through a
handheld terminal at the case or at the RC-2000
Unit.
IMPORTANT
Although the RC-2000 is not used for basic
DCU control operation, it is required for initial
store installation of DCUs, DCU data logging,
and application program downloading.
Inputs may be programmed to include:
•
•
•
•
•
•
Coil-in
Coil-out
Discharge air
Return air
Alarm sensors
Digital defrost termination inputs
The DCU also controls and monitors case
energy consumption.
The Case Power Module (CPM) is an output
control device used with the DCU. It includes a
high current relay for electric defrost. The CPM
connects to the DCU via an eight wire interconnect
cable, which provides power from the CPM to the
DCU. The cable also provides the control signals
from the DCU to the CPM. The CPM has been
designed to fit on top of, or under, cases easily.
Remote setpoint programming of the DCU is
also possible from the RC-2000.
Danfoss/ECI’s electronic case control
components (the DCU and the CPM) also work
together in line-up control. For line-up control,
daisy chain multiple CPMs together with one DCU
and combine them with either a suction or liquid
solenoid at the case.

Hill Phoenix Degree Master™1
The Hill Phoenix Degree Master load center is
a stand-alone control able to interface with the RC2000. One base unit load center is used per case.
The unit has a built-in transformer, which derives
power from the case. The Degree Master load
center possesses five universal inputs and includes
control relays for fans, lights, and basic
refrigeration solenoids. Optional expansion boards
provide additional control relays for electric
defrost, anti-sweat heaters, and electronic valve
(EEPR or EEV) control.
Degree Master inputs may be programmed to
include:
•
•

The Degree Master is programmable with a
handheld remote control unit. A local display
connects into the load center to view status and
programming changes. The display has a scrolling
screen and minimal functionality via two buttons at
the side of the screen. The buttons enable a small
subset of functions directly from the display, such
as a change in mode of operation. LED lights on
the display indicate:
•
•
•
Refrigeration status
Defrost status
Alarm status
1. Degree Master is a trademark of Hill Phoenix.
50
The Degree Master stores application code and
setpoint data in non-volatile memory. The
application code may be downloaded from the RC2000, eliminating the need for EPROM changes at
the Degree Master.
NOTE
Although an RC-2000 is not used for basic
Degree Master operation, it is required for initial
store installation of load centers, data logging,
and application program downloading. The
Echelon-capable RC-2000 may provide
installation functions and continue to serve as an
interface to a system of Degree Master load
center controls.
Remote setpoint programming of the Degree
Master load center is also possible from the RC2000.
Refer to Figures 23 and 24 in Appendix D of
this manual for Degree Master wiring diagrams.
Echelon Network Specifications
Introduction
Danfoss/ECI uses the Echelon FTT-10
Network for case controller applications. To
ensure the integrity of the Echelon communication
network, follow the specifications below.
Echelon Networks
Echelon specifies cable type and distance
limits for its existing networks. This section
specifies cable type and distance limits for two
Echelon-supported network configurations: the
Free Topology and the Doubly Terminated Bus
Topology. Danfoss/ECI recommends the FTT-10
Free Topology Star Configuration Network
because it offers more configuration flexibility. Be
aware that whichever network you choose
requires cable type and distance compliance
with the Echelon-specified guidelines.
IMPORTANT
To ensure network reliability, you need to
comply with cable type and distance limits.
Danfoss/ECI strongly advises that installation
drawings reflect the network layout and that
installation contractors adhere to them.
SUGGESTION
A copy of the installation drawing(s) should be
displayed onsite; this assists with network
troubleshooting.
Network Resistor Termination
The network requires that a termination
resistor be installed within the network loop. The
value and location of the resistor depends on the
loop configuration.
51
Echelon FTT-10 Network Free
Topology Star Configuration
The Free Topology Star Configuration
(optional) Network branches out in different
directions. Each of these branches is wired in a
daisy chain type configuration in succession from
one case to another.
IMPORTANT
Danfoss/ECI specifies a maximum of four
branches from one network hub.
NOTE
Limited exceptions to this general
recommendation may be made if the existing
conduit does not support this daisy chain
configuration. Contact Danfoss/ECI
Engineering for details.
The Free Topology Star Configuration requires
that the hub of the star be located within ten feet of
the network management device. This requirement
ensures easy isolation of the individual star
lengths, which makes it easier to diagnose network
problems with an ohmmeter or a LAN test meter
(TDR). Table 15 below lists the Free Topology
Network Specifications.
IMPORTANT
Be sure to document the configuration layout
PRIOR to installation. This gives you an
installation guide and network configuration
reference document.
SUGGESTION
Post the layout configuration document within
the store for maintenance personnel.

52
Singly Terminated Network (FTT-10
Networks Only)
A singly terminated network (star type
configuration) requires that one (1) 51ohm ¼ watt
resistor connect across the communication lines.
This resistor should be at a central location (i.e., at
the RC-2000 or the hub of the communications).
Drawing 29 below illustrates this type of network
termination.
NOTE
All Echelon capable RC-2000 products with
installed MIP Daughterboards are delivered
with one (1) 51 ohm ¼ watt resistor in place
across the LON connector.

Doubly Terminated Daisy Chain
Configuration/ FTT-10 Network
The Doubly Terminated Daisy Chain Network
restricts installation to a daisy chain configuration.
Within this network, the RC-2000 has two location
options: at either end of the daisy chain, or in the
middle of the daisy chain.
This network configuration provides greater
distance capability. The signal strength is greater
because of the limited signal reflection in a daisy
chain configuration.
NOTE
This type of network allows for convenient
isolation of the network segments.
The network routing should always be
documented and posted within the store for
maintenance personnel.
Table 16 below lists the Echelon specifications
for the doubly terminated daisy chain network
configuration. Be sure to adhere to these
guidelines when installing this network.

Network Connections
A reliably performing network depends on the
correct physical connection of the network cable.
The list below highlights the network connections.
Location connections on the RC-2000 and the
DCU:
1. RC-2000 CPU (new style part #
5120054400) MIP Daughter Board:
at the LON Connector.
2. RC-2000 CPU (old style part #
5120001400):
at the LON Connector (J6).
3. RC-2000/ Network HUB:
within ten feet of the RC-2000, at a secure
terminal strip.
4. Distributed Control Unit (DCU):
at the P1 LON Connector.
54
IMPORTANT
The physical connection should be checked for
the following conditions to verify integrity of
the network:
1. Ensure that connections do not have any
stray strands of wire that are not
properly inserted into the connector. (A
stray strand touching across the
conductors can cause a cross talk
problem).
2. After the connection is made, hold the
connector and apply a firm tug on the
cable ends to ensure that the connector
crimp on the cable is secure.
3. Verify that the proper Network
Termination is installed within the
network.
Doubly Terminated Network (FTT-10 )
This type of network MUST be a strict daisy
chain configuration and requires that two (2) 120
ohm ¼ watt resistors connect at each physical end
of the loop. Drawing 30 below illustrates a doubly
terminated buss network on a daisy chain
configuration.
IMPORTANT
Use doubly terminated network on a daisy chain
configuration ONLY.
The doubly terminated buss configuration
WILL NOT WORK on a Free Topology Star
Network.

Repeater Board
When the specified distance limits are
exceeded, network strength is degraded. A
Danfoss/ECI Repeater Board (Part #20055400)
preserves network strength when specified distance
limits are exceeded. This board connects in series
into a section of the network. A network operating
with a repeater board requires additional
termination to the network segment downstream
from the repeater board. Treat the downstream
portion of the network as a new network and apply
the network termination rules accordingly.
Drawing 31 below illustrates network termination
with a repeater board.

TROUBLESHOOTING
Introduction
Master Clear Procedure
This section guides you through problem
identification and corrective procedures when your
RC-2000 system malfunctions. System part
failures are addressed from a hardware standpoint.
Those discussed include: the RC-2000 Screen
Display, Keypad, Power System, Serial
Communication, Serial Modules, Relay Boards,
Temperature Sensors, and Pressure Transducers.
Follow the ten steps listed below to perform a
Master Clear of your data in RAM.
Data Corruption
Corrupt data (i.e., scrambled sensor names,
strange characters such as ♦: >*, etc.) cause the
RC-2000 system to malfunction. If this happens,
the system has a Master Clear function. Perform a
Master Clear if your data is corrupted.
IMPORTANT
The Master Clear function DESTROYS all
existing data in RAM. Use the Master Clear

Display Screen
Unlit Display
Your display screen may not always present
your data in an easy-to-view manner. Some
problems that you may experience with your
screen include: a rolling display, a blank display,
or an unlit display.
Possible Cause: CPU is not providing power for
the backlight display. (Before following the
corrective procedures, check the voltages on the
connector U41 (labeled backlight display). The
two outside pins should read 350VAC.
Rolling Display Screen
Possible Cause: The display screen may roll
because the jumper JP1 is not set correctly on the
RC-2000 CPU.
Corrective Procedure: Correct the JP1 Jumper
settings. Set them at:
•
•
4 meg if Version 4 or greater
2 meg if Version 3 or less
CAUTION
HIGH VOLTAGE!
Because of the high voltage level, use caution
when checking the CPU voltage. This voltage
level is high enough to electrocute!
If the voltage readings are incorrect:
Corrective Procedure: Change the CPU.
Possible Cause: The backlight is burned out if the
CPU passes a voltage check.
Blank Display Screen
Corrective Procedure: Change the display.
Possible Cause: The display screen may look
blank because the contrast is not set.
Corrective Procedure: Adjust the contrast knob
(it is located on the lower half of the CPU).
Possible Cause: The 25 Pin Blue Ribbon Cable
that connects the CPU to the display is not
connected correctly.
Corrective Procedure: Reconnect the cable
correctly.
IMPORTANT
On earlier hardware versions, make sure that the
display ribbon cable double row is plugged into
the top of both the CPU and the display. On the
ribbon cable, use both tops or both bottoms.
Proper connection is silk-screened on the CPU
board.
60
Power System Failure
The RC-2000 Power Supply Board contains
three red LEDs. In normal power system
operation, these LEDs are always lit. They show
the condition of the following power supply
voltages:
•
•
•
D11 represents 5VDC
D12 represents 12VDC
D13 represents 9VDC
7. Measure the DC voltages on J15 as
follows: use pin 12 as a Gnd reference.
WARNING
Accidental shorting may occur when checking
the voltages. This may DAMAGE your system.
NOTE
Pin one corresponds with the red side of the
cable.
An unlit LED indicates power system malfunction.
Power System Checks
When you experience power system
malfunction, go through the steps below to
determine the problem.
1. Make sure that the power switch on the
Power Supply Board is turned on.
2. Check and measure the incoming 115/
230VAC supply to the Power Supply
Board.
3. Disconnect the power at the power switch.
4. Check the fuse for continuity with an
ohmmeter.
5. Remove the black plastic cover from the
connector on J15 of the power board.
NOTE
You may have to disconnect the ribbon cable to
remove the plastic cover from the connector.
6. Reconnect the power at the power switch.

voltages again.
IMPORTANT
If you have performed all of the above checks,
and your RC-2000 is still in power failure, call
Danfoss/ECI Field Service at 410-403-4000 ext.
3238 for assistance.
9. If the voltage is still incorrect, you have a
problem with your power supply, change
it.
61
Serial Communication Failure
Serial Communication Status
A red blinking LED on each serial module
indicates normal communication status. A red
LED that does not blink indicates a serial
communication problem. The information below
about normal communication should help you to
determine where your system may need adjusting.
Danfoss/ECI recommends performing the general
communication checks listed below. If you still
experience serial communication failure, proceed
to the specific board sections, and perform the
recommended checks listed there.
1. The serial module or relay board must be
assigned in the program at least once
before the RC-2000 tries to communicate.
2. Starting at the RC-2000, proper polarity of
the serial communication wires must be
maintained through every serial module in
the loop.
3. Starting at the RC-2000, 12VAC power
must be supplied through every module in
the loop.
4. The transformer supplying the 12VAC
can’t be loaded down (do a load chart to
make sure it is not; refer to Table 4 in this
manual for load chart information).
NOTE
Remotely mounted boards require the 12VAC
power to be supplied locally.
5. Each serial module must have a unique
address within its particular family.
Serial Communication System Checks
If you verify all of the above, unhook the serial
communication wires from the RC-2000, and
check the following components of Serial
Communication for operation failure:
•
•
•
The CPU
The Serial Input Module(s)
(8 Channel Analog and Digital Input)
The Relay Board(s) (Digital Output)
Follow the troubleshooting procedures
recommended in the corresponding sections that
follow.
CPU Operation Failure
Possible Indication: On the RC-2000 CPU, the
Serial Tx (transmit) and Serial Rx (receive) LEDs
should blink back and forth.
Corrective Procedure: If they do not blink, the
communication problem may be in the serial
wires. Remove the 12VAC and Serial
Communication connectors (the J1 connector) at
the top right corner of the board. Turn the board
off for 15 seconds, and then turn it back on. The
red Serial Tx (transmit) should blink; this indicates
a communication attempt. If it doesn’t blink, your
CPU may be damaged. Contact an Danfoss/ECI
representative for further information
NOTE
In the RC-2000 Version 4.00 or higher, the I/O
point must be assigned in the program for the red
Serial Tx (transmit) to blink.
Corrective Procedure: If they blink, but you
still experience serial communication failure, the
communication problem may be in the serial
modules. To determine this, remove all of the I/O
boards from the loop and start wiring them in one
at a time until you find the one that is causing the
serial LEDs to stop blinking.
62
Board Status Screen
The Board Status Screen (see below) in the
RC-2000 helps to troubleshoot any serial
communication problems. The RC-2000 scans
each serial module for correct communication and
shows the status of the serial modules connected to
the RC-2000. This screen displays the following
status messages:
•
•
•
•
•
On Line
Off Line
Unused
Need Cnfg
Checksum
This status data aids in troubleshooting serial
communication, and helps you to identify specific
board problems.
For example,
The Board Status screen displays a “NeedCnfg”
message if a board is assigned as one type, but the
hardware is configured for another.
It also displays a checksum message if the board
assigned is communicating with a lot of errors.
(This is possibly caused by high voltage.)
On Line indicates that the module is
responding correctly.
To access this screen from the Banner Screen:
Off Line indicates that the module is assigned
in the setpoints, but is not responding.
Unused indicates that the module is not
assigned in the setpoints program.
Need Cnfg indicates that a board is assigned as
one type, but the hardware is configured for
another.

Serial Input Module Failure
(8 Channel Analog Input/Digital
Input)
A red blinking LED on each serial module
shows normal communication status. If a red LED
is not blinking, you should follow the list of checks
below to ensure normal communication.
1. Verify communication status. If the red
LED is not blinking, communication status
is not normal.
2. Verify the board has a unique address
within its family.
3. Verify the input assignment in the
program.
4. Verify 12VAC power to the module.
5. Verify the DC inputs with nothing
attached. They should read:
Temperature:
Pressure:
0-10V:
Digital Input:
5VDC
6VDC
10VDC
5VDC
Serial Relay Board Failure
(8 Channel Digital Output)
A red blinking LED on each relay board shows
normal communication status. If a red LED is not
blinking, note the information below about normal
communication.
1. 12VAC power must be applied to the relay
board.
2. The relay must be assigned correctly in the
program.
3. Normally Open and Normally Closed
contacts must be connected correctly.
Check the 3 amp, 250VAC fuse on the
common leg of each relay.
4. You may override relay operation. The red
LEDs indicate that the relay is energized.
Blinking yellow LEDs indicate that the
relay is in an override state (i.e., either
energized or deenergized.)
NOTE
When a relay board fails, all relays fail to
normally closed status.
If the DC inputs are incorrect, check the
configuration of the modules. If the module
configuration appears correct, most likely the
module is bad. Change the module.

Temperature Sensor Failure
If you suspect temperature sensor failure,
follow the system checks listed below to determine
problem areas:
1. Measure the DC voltage from the sensor
number to the common terminal.
2. Convert the voltage to a temperature with
the conversion chart listed in Appendix A
or calculate the conversion with this
equation:
Temperature = (V measured – 2.554) x 180
3. Compare the temperature to the display.
If the temperature agrees, the problem is
probably in one of three areas:
a. The Sensor. It is either offset, or it
needs to be replaced.
b. The Connection Wire.
•
•
•
Check for continuity on the cable
run.
Make sure the cable is clear of
high voltage.
Verify connection at sensor.
NOTE
With the cable connected at the module end, and
no sensor attached, the voltage reading should
be 5VDC at the sensor end.
c. The Sensor Placement. If it is placed
in discharge or return, etc., make sure
that the sensor is in air flow.
If it is strapped to an evaporator or
other pipe, make sure it is insulated.
If you are reading the air
temperature, insulate the sensor
from metal surfaces.
67
Pressure Transducer Failure
If you suspect pressure transducer failure,
perform the following checks in an effort to
identify the problem area:
1. Measure the voltage between the +12VDC
terminal and the common terminal on the
Serial Analog Input Module. The voltage
should read 13-16VDC at the bottom of
the module.
If it does not:
The module is bad, or the module is not
receiving proper power.
2. Check the status LED on the serial
module. It should be blinking.
If it is not:
You may be experiencing serial
communication failure. Refer to the Serial
Module information of this Troubleshooting section.
3. With the transducer attached, measure the
voltage between the sensor number
terminal and the common terminals on the
module.
Use the conversion tables in Appendix A
or the pressure to voltage equations
provided to determine if the pressure
reading in the display agrees with the
measured reading.
4. Check the module configuration to make
sure it is a pressure module.
68
Pressure to Voltage Conversion
Equations
Suction Pressure = (V measured - 1) x 20
Head Pressure = (V measured -1) x 100
For variable speed operation only, use the
following equations:
Oil Pump Output Pressure =
(V measured - 1) x 20
Display Oil Pressure =
(Oil Pump Pressure) – (Suction Pressure)
•
NOTE
If the reading is 0VDC, the white wire
or transducer is shorted or the black/red
wires may be open.
•
If the reading is 12VDC or greater, the
transducer is defective.
•
If the calculated pressure does not agree
with the RC-2000 display, the module is
out of calibration or there is a problem
with the CPU. Check for a sensor
offset in the RC-2000. You may need to
replace the input module.
•
If the calculated pressure agrees with
the display, the transducer is out of
calibration. If the transducer is only out
(+) or (-) 5 lbs., the sensor can be offset
in the program. If the sensor is out more
than (+) or (-) 5 lbs., replace the
transducer.

Check for the correct wire connection and
termination at the transducer (e.g., each
connection of a CT should have a wire
connected and terminated at the
transducer).
Make sure the “pig-tailed” wire or shorting
blocks are not shorting out the CT
secondaries.
Make sure that you are using the correct
CT ratio.
NOTE
Label this value on the switchgear cabinet for a
quick and accurate reference.

kW Watt Transducer Checks
Make sure incoming voltages are properly
fused.
Make sure you are using an applicable
transducer model number for the
application.
Make sure you are using the correct
voltage and that the CT is wired correctly.
kW Watt Transducer Troubleshooting
Procedures
1. Check the phase rotation for proper
labeling and hookup.
2. Disconnect the wires for the output voltage
from the transducer. All readings are done
from the DMM.
3. Set the meter on the 10VDC scale (or next
highest range), and connect to the watt
transducer. Terminal 1 is negative and
Terminal 2 is positive.
4. Ensure that the voltage reading on the
DMM is positive. If not, go directly to
the kW Watt Transducer Troubleshooting Checks section.
5. Verify the maximum CT value and
calculate the maximum kW at 10VDC (per
the example below).
Use this equation to determine the maximum
CT value:
[(the CT scale factor*) x (the CT max**) =
(the max. CT value)]
For example:
With 3000:5 current house power @ 208V,
multiply the following per the equation above:
(.36 x 3000) = 1080
to determine: a 1080 kW at 10VDC yield
or 108 kW/volt (the max. kW @ 10VDC).
*For a list of CT scale factors, see Table 27 in
Appendix C.
**The CT max is the first number in a standard
CT ratio rating (i.e., for a ratio of 3000:5, use
3000 for the CT max value).
6. Multiply the voltage reading on the DMM
by the kW/V value.
For example:
For a voltage reading on the DMM of 3.3 VDC
output and a kW/V value of 108:
multiply
(3.3VDC output x 108 kW/V = 356.4 kW)
for a yield of 356.4 kW.
69
7. Evaluate the kW value calculated and
displayed on the controller for correctness.
Follow these procedures to do this:
•
•
•
•
Call the store operations personnel for a
normal operational kW value. This
determines whether or not the value is in
the “ball park.” If the store is equipped
with monitoring devices (such as a power
meter with a kW readout), use the
equipment to find an accurate value for
comparison purposes.
Use external monitoring equipment
(Dranetz or Esterline Angus) if available,
to find an accurate value for comparison
purposes.
For rack loads, a fairly accurate reading
can be obtained by using a voltmeter and
clamp-on ammeter.
Take current readings on each phase and
multiply them by the voltage to neutral of
that phase. Add all three phase values
together. This gives a volt-amp value that
is close to the kW usage. This doesn’t take
into account power factor, but is a good
working value in the absence of other more
exact methods.
kW Watt Transducer Troubleshooting
Checks
1. Check the fuses.
2. Check the voltages at the watt transducer
for the correct value.
3. Check the CT secondary currents at the
watt transducer. They should be less than
5 amps AC.
4. Verify that the correct scale factor is used
on the controller.
NOTE
Typically:
If one CT is reversed, the output is positive, but
reduced.
If two CTs are reversed, the output is as above,
but negative.
If all three CTs are reversed, the output
magnitude is correct, but is negative.
70
A good indication of mixed CT hookup
includes:
Sparking when shorting or unshorting the CTs
(while connected to the transducer).
NOTE
A CT, if connected to the proper terminals,
DOES NOT spark when shorted.

status checks you can perform via this LED’s
properties.
Alarm Condition Steps at the KWIC
Echelon Assembly
If the status LED on the PIB fast blinks (see
Table 17 above), your KWIC device may be in an
alarm condition. If you suspect the KWIC
Assembly is in alarm condition, perform a Check
Node to try to determine the Echelon Error Code
(see Table 18). Follow the Troubleshooting
Procedure listed in Table 18 for the Error Code you
have determined.
3. If a KWIC Echelon Assembly is
configured without the Expansion
Assembly connected to the Echelon
Assembly via the interconnect cable at the
time of configuration.
4. If the RC-2000 is reconfigured to modify
the number of Network Digital Output
boards within the system (either adding or
removing a Network Output Module after
the KWIC Assembly was already
configured).
5. If an Output Module on a KWIC Assembly
has malfunctioned.
NOTE
Hot Swappable Output Modules on a KWIC
Output Module may be removed and replaced
with the same type of module without
reconfiguring the KWIC Assembly.
The list that follows catalogs the most common
reasons you may find the system in an alarm
condition:
1. If an Output Module on a KWIC Assembly
is replaced with a different type of output
module after the original Configure
Function was performed.
2. If a KWIC Echelon Assembly is
configured without all programmed Output
Modules installed at the time of configure.
71
KWIC/ Echelon Hardware Checks
Improper hardware hookup causes the KWIC
device to malfunction. To determine if the KWIC
device’s hardware is hooked up correctly, make
sure that the following is done:
Make sure 24VAC POWER is present at the
J105 connector’s top two pins.
Remove the first output module from the
Kysor assembly to see the channel group selector
switch (SW200) on the Buss board. The switch
should be set as follows:
•
•
“Up:” 1-4 (for the Assembly with the
Echelon Engine) and
“Down” 5-8 (for the KWIC Assembly
used for expansion)
Make sure all output modules are connected to
both the driver assembly and the expansion
assembly.
NOTE: If ALL output modules are not
installed, reconfigure the KWIC assembly.
When using a KWIC EXPANSION Assembly,
make sure it is CONNECTED to the KWIC
Driver Assembly in the Expansion port with ECT
Chassis Interconnect cable (Part # 5025014400-02,
-04, or –20).
Check the cable connection for the Echelon
communication at the P1 connection on the
Echelon Engine and at the LON connector on the
MIP Daughter Board on the RC-2000.
IMPORTANT: The Echelon communication
at the P1 connection on the Echelon Engine must
be secure for the device to communicate properly.
72
Check that one 51ohm ¼ watt resistor is
connected across the connector at either the P1
connection on the KWIC Echelon engine or the
LON connector at the MIP Daughter Board at the
RC-2000.
IMPORTANT: No more than one 51ohm
resistor should be installed on a single network.
Make sure that the yellow LON LED (LD1) is
lit on the RC-2000.
Suggestion: If it is not lit, reset the RC-2000
by interrupting the power.
Check the status. If the status does not end
with the four digits [0000], then refer to Table 18
for a description of specific error codes. If the
error code is not listed, then perform the node
check procedure found in the software setup
section of this manual.
IMPORTANT: The digital output interface
setup shouldn’t have more outputs allocated than
the KWIC assemblies have modules to support.

KWIC/RS485 Assembly
Troubleshooting
To determine if the KWIC malfunction is the
result of improper RS485 communication setup,
follow the procedures listed below:
Look at the green status LED (LD2) on the
RS485 Engine Board. Upon power-up it goes on,
and remains on during the power-up procedure
(approximately 15 seconds). After power-up,
however, the green light should go off.
If the status LED remains on AFTER the
power-up procedure, a problem has been detected
in either the program or hardware.
KWIC/RS485 Hardware Checks
Perform the following checks to determine if
the KWIC malfunction is the result of a hookup
error:
1. Check the wiring of the P1 connector on
the RS485 Engine Board. This connector
is for the RS485 network connections.
Observe the polarity on this connection to
make sure it is correct throughout the loop.
2. Check connector J105 on the PIB Engine
Board, this connector is for power
connection. Make sure that 24VAC is
applied at the J105 connector’s top two
pins.
3. Remove the first output module from the
Kysor Assembly to see the channel group
selector switch (SW200) on the Buss
Board. The switch should be set as
follows:
• “Up:” 1-4 for the KWIC RS485
Assembly
• “Down:” 5-8 for the KWIC Expansion
Assembly
4. Make sure all output modules are
connected to both the Driver Assembly
and the Expansion Assembly.
NOTE
If ALL Output modules are not installed, remap
the KWIC Assembly.
5. When using a KWIC Expansion Assembly,
make sure it is connected to the KWIC
Driver Assembly in the Expansion port
with ECT Chassis Interconnect cable (Part
# 5025014400-02, -04, or –20).
6. On the RS485 Engine Board, verify that
Switch Block 1 is properly set for board
addressing.
7. On Switch Block 1, dip switches 6 & 7,
verify that the baud rate setting is correct,
as compared to the other I/O boards and
the CPC controller.
8. On Switch Block 2, check dip switches 1
& 2 for uniform polarity settings within the
RS485 communication loop.

Need to install and remap the system
Start Up/ Remap Procedure
If the system is not responding to commands, it
may need to be remapped.
NOTE
You must perform the remap/initialization
process upon initial KWIC Device start up or
KWIC Device configuration changes.
You do not have to perform the remap process
for dip switch changes or to replace failing
modules of the same type.
The malfunction within the unit may be the
result of the software programming if:
•
•
•
hardware settings check out okay,
the system does not need to be remapped,
after performing the remap process, the
KWIC Device still does not respond to
commands.
If you think this may be the case, consult an
authorized service technician.
Remap System Steps
Follow the steps below if the system needs to
be remapped.
1. Power down the KWIC Device by
disconnecting the J105 24VAC connector
on the PIB Board.
2. Set all dip switches on Switch Blocks S1,
S2, and S3 as per the system guidelines.
3. Set Switch 8 on Switch Block 1 (S1) to the
up ‘ON’ position.
4. Power up the KWIC Device by
reconnecting the J105 24VAC connector
on the PIB Board. [Upon restart of the
KWIC Device, wait for the green LED
(LD1 ‘ST’) on the RS485 Engine board to
go out (approximately 15 seconds).]
5. Push the Cnfg/Svc Switch on the PIB
Board until the status light on the PIB
Board lights.
6. Set Switch 8 on Switch Block 1 (S1) to the
down ‘OFF’ position.
7. Watch for the green LED (LD1 ST) on the
RS485 Engine to go off (when the green
LED goes off, the remap process is
finished. The system is ready for
operation).
NOTE
If any switch is changed, the change does not
take effect until the power is removed and
reapplied.

CAUTION
TO AVOID POTENTIAL EXPLOSION WHEN INSTALLING OR SERVICING A
CURRENT TRANSFORMER ON A LIVE CONDUCTOR:
ALWAYS short the secondary wires to each other prior to connecting or disconnnecting when
installing or servicing a CT on a live conductor. The CT strives to output the ratioed current,
and eventually it will break down the insulation or air between the terminals.
AN EXPLOSION MAY OCCUR!

Addendum to Form No. 4464402700
RC-2000 Refrigeration Control Installation Manual
Date: February 15, 1999
Part Description: RC-2000 Power Supply
Part Number: 5120105400
RC-2000 LINE POWER FILTERING REQUIREMENTS
Introduction
The ECI RC-2000 Power Supply has been
redesigned. Additional filtering for the line power
and improved transformer mounting are now part
of the power supply.
NOTICE
Since September 1998, all RC-2000 units were
shipped with two line power filters (ECI Part #
2112810400). These line power filters were to
be installed at the following locations in the RC2000 system:
1. Line power to the RC-2000
2. Line power to the I/O transformer
The new RC-2000 power supply (Part #
5120105400) eliminates the need to install a line
filter for the RC-2000 line power.
Installation Requirements/
RC-2000 Power Supply,
Part # 5120105400
Be aware that all future shipments of the RC2000 will include ONLY ONE line power filter.
The line power filter that arrives with the RC2000 shipment should be installed to filter the
primary supply voltage for the I/O transformer
(ECI Part # TF-6).
IMPORTANT
Any RC-2000 unit with power supply
#5120102400 will require a line power filter to
be installed at the RC-2000 line power. Details
of the connection are provided within
Applications Engineering Notice #1024, Rev. C.
Serial I/O Primary Line Power
Filtering
Each primary line power feed to ECI
transformers will need to have a line filter installed
within 12” of the transformer. This requirement
applies to all RC-2000s, regardless of which power
supply is installed.
NOTE
The RC-2000 includes one (1) line filter for the
I/O power transformer as part of the original
part number.
Any remotely mounted I/O will require a line
filter to be installed within 12” of the local
transformer as per the connection diagram on
the back of this sheet. These line filters may be
ordered via ECI line filter Part # 2112810400.
Please address any questions about these
installation revisions to the ECI Applications
Engineering Department at 410-403-4000 between
the hours of 7:00 A.M. and 4:00 P.M. Eastern Time,
Mondays-Fridays, or to your local ECI Sales
Engineer.
Addendum to Form No. 4464402700
RC-2000 Refrigeration Control Installation Manual
Date: February 15, 1999
Part Description: Pressure Differential Board
Part Number: 5120118400
PRESSURE DIFFERENTIAL BOARD
Introduction
ECI now offers a Pressure Differential Board
that translates the differences of two pressure
inputs into a differential output. The new Board
provides outputs for the higher operating pressure,
the lower operating pressure, and the difference
between them, whereas a standard pressure
differential transducer only provides output for the
differential pressure. By using all three pressures,
the new Board offers more refrigeration control
flexibility.
Upon receiving the pressure readings, the
Pressure Differential Board outputs the higher
operating pressure, the lower operating pressure,
and the difference between them, to an ECI Sixteen
Channel Universal Input Module (SUI16). For
correct operation, ECI recommends following the
connection requirements listed below and referring
to Figure 1, attached to this addendum.
Connection Requirements
1. Both pressure transducers connected to the
Pressure Differential Board MUST BE the
same ECI Part Number. Table 1, below lists
the ECI Pressure Transducers.

input connections (labeled “COM”) on the
SUI16.
3. Connect J3 (High, Low, and Diff) on the
Pressure Differential Board to a signal
input connection (labeled 1-16) on the
SUI16. (Signal input connections 1-16 are
the signal for the respective pressure as
labeled on the Pressure Differential
Board.)
