SECTION 1

INTRODUCTION

1.1 Description

The CN600 Series is a second generation of industrial scanners based on the field proven CN100 six zone temperature monitor/alarm system. Several models and options are available. The CN600 Series is a microprocessor based scanner which accepts signals from thermocouples or RTD's. In the basic unit, six zones are sequentially scanned with a selectable display rate of 1 to 40 seconds each. A single output relay is provided to indicate an alarm condition on any zone. The faceplate has been arranged to call attention to an alarm condition by flashing the main temperature display and indicating the zone in alarm with a flashing zone number display. To prevent alarm on startup, Lo alarm is not activated until enabled zones cross Lo alarm setpoint.The CN600 Series implements a security password to protect certain functions.

Up to ten scanners can be connected in parallel to a single RS-232 communications port on a PC. Each scanner is assigned a serial number from 0 to 9. The computer uses these numbers to determine which scanner unit to address at a given time. A simple set of menus is provided in the software which allows the operator to change the settings of each connected scanner unit and display individual operating parameters. For users with advanced software capabilities, see Section 2.4 for an operating protocol.

The following screen menus are provided:

1. SELECT PORT- Scans all available PC ports and indicates which port is connected to scanners.

2. MAIN MENU- Allows the following operations:

• CONFIGURE UNIT allows individual unit type selection, including: T/C Type, Temperature Scale, Latching or Nonlatching Alarm, and Hi, Lo or Hi/Lo Alarm.

• RUN one unit display or two units simultaneously.

• SET SETPOINTS allows changes to individual unit Hi and Low setpoints, scan time settings and allows zones to be enabled/disabled.

2.4 Operating Protocol for RS-232 Communications

The CN606 Scanner is designed with standard RS-232 three wire serial communication capabilities. Up to ten scanners can be parallel connected to a single PC. The transmission line is held in tristate to avoid cross-talk between scanners except when the computer addresses a specific scanner for communication.

Configuration

BAUD rate = 4800 Data bits = 8 Parity = N

Stop = 1 ( or 2 on some computers) Communication software for the PC is written in Visual Basic. This software package has been created to operate on PC Windows 95 platform meeting the minimum requirements. Customers can communicate with CN606 scanners through a PC by using the following protocol:

• Scanners will not initiate communication. The RS-232

Command Module (computer or similar device) must initiate.

• All communication is in ASCII format except Check Sum. Check Sum is generated by hexadecimal addition with carry of data string (one byte).

• To start communication, the Command Module must send alert code ASCII [L] hex 4C. This commands the scanners to cease RS232 communication and listen for an ID Code. The Command Module then sends the Identification Number for the scanner that it needs to address, ASCII [0 to 9] hex 30 to 39. The identified scanner will then expect a command code. All the other scanners on-line will wait for the next alert code.

• Command codes are divided into two groups:

ASCII Zones/ Alarms/ Scan time 15 bytes 1 byte [binary] zones 1 to 6 [0011 1 111] = (3F h) 1 byte [binary] zones 7 to 12 [0 011 1111] = (3F h) 1 byte [binary] zones 1 to 6 Hi alarm [0011 1111] = (3F h) 1 byte [binary] zones 7 to 12 Hi alarm [0011 1111] = (3F h) 1 byte [binary] zones 1 to 6 Lo alarm [0011 1111] = (3F h) 1 byte [binary] zones 7 to 12 Lo alarm [0011 1111] = (3F h) 2 digit scan time + check sum

ASCII Model/ Password/ ID#/ # of zones 13 bytes 4 digit model code 4 bytes 4 digit password 4 bytes 2 digit ID# 2 bytes 2 digit number of zones 2 bytes + check sum 1 byte

ASCII Coded Setpoints 97 bytes 12 zones, 4 digits each zone [Lo setpoint] 48 bytes 12 zones, 4 digits each zone [Hi setpoint] 48 bytes + check sum 1 byte

ASCII Coded Temperature 49 bytes 12 zones, 4 digits each zone 48 bytes + check sum 1 byte

Group 2. Commands preparing scanner to receive data:

ASCII [m] hex 6D = Model/ Password/ ID# ASCII [e] hex 65 = Zone enable/ Scan time ASCII [s} hex 73 = Setpoints

ASCII Model/ Password/ ID# 10 bytes 4 digit model code 4 bytes 4 digit password 4 bytes 1 byte ID 1 byte + check sum 1 byte

Group 1. Commands requesting data from the scanner: ASCII [A] hex 41 = Zones/ Alarms/ Scan time ASCII [M] hex 4D = Model/ Password/ ID#/ # of zones ASCII [S] hex 53 = Setpoints ASCII [T] hex 54 = Temperature

ASCII Zone enable/ Scan time 7 bytes 1 byte [binary] zones 1 to 6 [0011 1111] 2 bytes 1 byte [binary] zones 7 to 12 [0011 1111] 2 bytes 2 digit scan time 2 bytes + check sum 1 byte

ASCII Coded setpoints 97 bytes 12 zones, 4 digits each zone [Lo setpoint] 48 bytes 12 zones, 4 digits each zone [Hi setpoint] 48 bytes + check sum 1 byte

• The four digit code for model selection is as follows:

INSTALLATION

3.1 Unpacking

Upon receipt of shipment, inspect the container and equipment for any signs of damage. Take particular note of any evidence of rough handling in transit. Immediately report any damage to the shipping agent.

Digit 1. (msd)

0 = Overheat Alarm 1 = Underheat Alarm 2 = Hi/ Lo Alarm

Digit 2.

0 = Latching Relay °C 1 = Latching Relay °F 2 = Nonlatching Relay °C 3 = Nonlatching Relay °F

Digit 3. (preset at the factory)

0 = Thermocouple 1 = RTD

Digit 4. (Thermocouple units only)

0 = Type B 1 = Type C 2 = Type E 3 = Type J 4 = Type K 5 = Type R 6 = Type S 7 = Type T

Digit 4. (RTD units only)

0 = 100 ohm Platinum 1 = 100 ohm Nickel 2 = 10 ohm Copper

Remove the packing list and verify that all equipment has been received. Each package should contain:

• Scanner (CN606 or CN612)

• Operator's Manual

• RS-232 Software

• Two mounting slides with screws

• Power plug (9 pin)

• RS-232 plug (3 pin)

• Two T/C plugs (6 pin)

• (CN612 only) Two Additional T/C plugs (6 pin)

If there are any questions about the shipment, please call the Customer Service Department.

NOTE: The carrier will not honor any claims unless all shipping material is saved for their examination. After examining and removing contents, save packing material and carton in the event reshipment is necessary.

3.2 Mounting

Select a location for the monitor that is free from excessive shock, vibration, dirt, moisture and oil. Mount the monitor into a 3 5/8" (92mm) square cutout. The monitor as shipped is 1/4 DIN (92mm square), so it does not have to be removed from it's housing to be mounted.

Remove the two screws that secure the mounting slides. Remove the slides and insert the case into the cutout from the front side of the panel. Reinstall the two slides and two screws. The length of the slides must be reduced if the monitor is to be mounted in an extra thick panel.
