1 Introduction

The Turbocor Service Monitor program is a rich, user-

friendly, graphical user interface designed to control the

Turbocor compressor and to provide status information

about the compressor. Furthermore, it can be used as a tool

for troubleshooting purposes.

This manual describes the functions provided by the

Turbocor Service Monitor program.

System Requirements

2Danfoss Turbocor Compressors Inc.

ECD-00007M Rev. 1

2 System Requirements

The monitor program must be installed on a PC that meets

the minimum requirements specified in Table 1. For

optimum performance, a 533 MHz Pentium or higher CPU

with 128 MB RAM running Windows 2000 (SP4) or XP is

recommended.

The monitor program was developed for the .NET

Framework and requires the .NET Framework to be

installed on the PC where the program runs. Microsoft

provides a re-distributable installer, Dotnetfx.exe, that

contains the common language runtime and .NET

Framework components that are necessary to run the

monitor program. Before installing the monitor program,

the .NET framework 1.1 re-distributable must be installed.

This can be downloaded from the Microsoft website.

The latest Windows service packs and security updates

should also be installed on the PC.

Table 1: Minimum Requirements

Processor 533-MHz Intel Pentium-class processor

Operating System The .NET Framework 1.1 Re-distributable is supported on the following

platforms:

• Microsoft Windows® Server 2003 (.NET Framework 1.1 is installed as part

of the operating system)

• Windows XP Professional

• Windows XP Home Edition

• Windows 2000

• Windows Millennium Edition (Windows Me)

• Windows 98

• Microsoft Windows NT® 4.0 Service Pack 6a

The .NET Framework 1.1 Re-distributable cannot be installed on 64-bit

computers; Windows NT 4.0 Terminal Server is not supported

Memory 128 MB of RAM, 256 MB recommended

Hard Disk 110 MB of hard disk space required, 40 MB additional hard disk space

required for installation (150 MB total)

Display 800 x 600 or higher-resolution display with 256 colors

Input Device Microsoft mouse or compatible pointing device

Other Install the latest Windows service packs and critical updates from the

Windows Update site.

Installation of the .NET Framework 1.1 is split into two parts: the core

and language packs. The core contains everything you need to run .NET

Framework applications; all dialog boxes and error messages will be in

English. If you want dialog boxes and error messages in another

language, you must also install the corresponding language pack. For

more information, see the .NET Framework Downloads page.

3 Getting Started

3.1 Cable Connection

The monitoring program communicates with the

compressor via the Modbus* protocol using either the

RS232 or RS485 connection at the Chiller Interface

module. RS485 communication requires an RS485/RS232

adapter (user-supplied). RS232 communication is

recommended for cable lengths not exceeding 15 meters

(50 feet) between the PC and compressor. For cables that

run up to 100 meters (328 feet), use the RS485

communication line. Always use shielded, twisted-pair

cable for data communications

*The Modbus protocol was originally developed to exchange information

between products on the factory floor. This protocol has become a de facto

standard for exchanging data and control between PLC systems. Modbus is

a registered trademark of Modicon Corp.

3.1.1 RS232 Connection

1. Connect one end of the RS232 cable (user-supplied) to

the DB9 connector on the Chiller Interface module; see

Figure 1.

2. Connect the other end of the cable to an available COM

port on the PC.

3. Confirm that jumpers JP2 and JP7 are in proper

positions before starting.

JP2 is the Modbus termination jumper. Install the

jumper if the Modbus connection is at the end of a

cable run.

Remove JP7 to enable RS-232 communication with the

PC.

3.1.2 RS485 Connection

1. Connect the RS485/RS232 adapter directly onto the PC

COM port.

Connect the other side of the adapter to the Modbus. Figure

2 shows the PC and adapter connections to the Modbus for

a single compressor application. Ensure that the termination

jumper (JP2) on the Chiller Interface module is installed.

Figure 3 shows the PC and adapter connections to the

Modbus for a multiple compressor application. In this case,

set the termination jumper only on the Chiller Interface

module that is connected at the end of the Modbus cable

run.

3.2 Monitor Program Installation

The monitor program is installed on the PC and

communicates with the compressor using the ModBus

protocol over a RS-232 or RS-485 serial link. Administrator

privileges may be required to install and remove software

on the PC.

NOTE:

If a previous version of the monitor program is already

installed on the PC, it must be uninstalled before proceeding

with the current installation. To uninstall the monitor

program: from the “Start” menu, select “Settings” →

“Control Panel”. Double-click “Add/Remove Programs”.

From the list, select “Danfoss Turbocor Service Monitoring

Tool” and then click the “Remove” button.

Installation Procedure:

1. Insert the monitor program CD into the drive.

2. In Windows Explorer, navigate to the

Turbocor_Service_Tool_Setup.msi file. Double-click

the file to launch the setup wizard.

3. Follow the instructions provided by the wizard to

complete the installation.

4. Click the Close button to exit the setup wizard.

3.3 Starting the Monitor Program

To start the monitor program: from the “Start” menu, select

“Programs” →“Danfoss Turbocor Monitoring Tool”.

Access Code - The access code controls access to all

adjustable parameters. The default user access level on

power up is read only. Enter the code that corresponds to

the access level you require. Contact Turbocor Product

Support to obtain the required access code.

1. Once the serial port connection data has been set, click

the Connect button. At this point, connection status,

compressor details, and user access level appear in the

right-hand pane of the dialog box.

2. If necessary, change the access level. Enter the access

code in the “Access Code” parameter box, then click

“Change Access Level”. Confirm that the correct

access level has been set on the right-hand pane of the

dialog box.

NOTE:

The access level connection cannot be changed prior to a

establishing connection.

Entering the wrong access code more than 3 times will lock

out all communications until a cycle of the power is

performed.

3. Click the “OK to start monitoring” button.

4 Compressor Configuration

4.1 Using the Setup Wizard

The monitor program features a commissioning setup

wizard to guide the user through the complete compressor

configuration process.

1. To launch the commissioning setup wizard, select

“System Commissioning” from the “Advanced” menu

item. The introduction screen for the commissioning

setup wizard appears; refer to Figure 5. Click Next.

(To bypass the setup wizard and use a saved

configuration file to setup the compressor, check the

checkbox and click Next. Continue with 4.2 "Using a

Saved Configuration File" on page 13.)

2. Select the appropriate units of measurement (metric or

imperial). Refer to Figure 6.

3. Select the appropriate compressor control method.

There are three modes available:

• Analog Input: compressor loading controlled using

an analog demand signal of 0-10 VDC from an

external controller. The variable demand signal

corresponds to the range of 0-100% maximum

power available.
