1. Introduction
This manual contains information for the installation, operation and tuning of your Accuthermo ATEC302
TE Panel Temperature Controller, ATEC402 Din-Rail TE Temperature Controller and FTX700 High
Power TE Amplifier/Driver. ATEC302 can also be connected to FTX300 or FTX100 H-bridge amplifiers.

The Accuthermo microprocessor controllers are FUZZY ENHANCED “proportional + integral +
derivative” (PID) controllers that come in with industry standard DIN72x72mm and Din-Rail size. The
input is configurable and allows selection of input between thermocouples, RTD and Thermistor*.
The TE Amplifier is capable of running up to 700Watt of power. It is a very efficient TE power amplifier.
The amplifier can run without force air (fan) under 350Watt in ambient condition. Over 350Watt, it is
recommended to add in fan for proper ventilation.
The controller can talk to PC through a dedicated USB cable or a RS232 communication daughter card
(option on ATEC302) that Accuthermo provides. And it comes with very sophisticated PC software for
FREE.
The controllers can also be serial linked together and talk to one PC by using RS-485 communication
method (option on ATEC302, default on ATEC402).
Caution: When USB cable is connected to the controller, the RS232 or RS485 communication daughter
card should not be plugged inside the controller. Otherwise, it will have conflict.

1.1 Using Manuals
There are three manuals for this system:
Reference Manual (this one): The manual is designed for user who wants to use the front panel buttons to
controller the system. The users who want to write their own program to control the system. It provides the
instructions of how to use the front panel buttons, the parameter table. Users are encouraged to read the
following two manuals first.
TE Temperature Controller System Installation Guild: This is the must read document for user to putting the
system together. It is a step-by-step guide, with lots of pictures for easy reading.
Software Installation Guild & User Manual: The software contains a very completed function sets for user to
change parameters; control and run the system; monitor and logging data. It took us more than a year to design
and develop the software. More than 95% of the users find the software can satisfied their task without
re-writing their own software.

2.9 Power Input
The default setting is 9V-36V DC. There is a jumper inside the controller that you can set it for a fixed 5VDC.
When using 5VDC as supply, the USB cable CANNOT work.
When using 5V setup. Not only change the 5V jumper position; there are two components next to jumper R111
and D101 needed to be shorted. Otherwise, they would affect the voltage drop of 5V.
If the R111 and D101 are shorted, the ’Input power reverse protection’ is no longer working. Please be very
caution on it. If that was damaged, it won’t be covered by our standard warranty.
If the jumper has converted for 5VDC, connecting to supply power other than 5V will damage the
system; and the warranty is void.

3. Front Panel Operation
User should learn some front panel operation during hardware installation. This section will describe more in
detail.
3.1 Push Buttons
Referring to 2.4 Menu Overview, users can select different level of menu and change the parameters using these
four push buttons.
i. Return to Top Level Display
If you make mistake, just press & two buttons, it will return to top level display for normal
operation.
ii. Go to Menu Mode
Press and hold two buttons for 5 seconds, the screen will jump to menu mode. The RED LED line
should show . It is the first level menu. By pressing button, user can select various top menus in
sequence, using button to select the previous menu.
Note: If keypads are locked, you can only run our PC software to unlock it (page. 16)
iii. Select Parameters in Menu
The parameters selection in each menu is in a loop format. At each top menu, press button to select its
parameters. If you miss it, just press continuously until it reaches the parameter you are looking for.
iv. Changing Parameter value
The parameter is Number (ex. temperature): To change a parameter value, press to select the digit you

Accuthermo Technology Corp. 12
want to change, the specific digit LED should be highlighted. Then press to add number or to
reduce the number. Press to confirm the value.
The parameter is Type (ex. sensor type): Use or buttons to choose the desire one.
3.2 Power UP Display Sequence
When power up the controller, the display will show from Top/Bottom display in sequence:
LED all on test →Sensor type/Temperature unit →High Limit/Low Limit
→PV(process value)/SV(set value)
3.3 Change the SV (Set Value) Number
i. Use to highlight the digit you want to change.
ii. Use or buttons to change to the value desired.
iii. Press to confirm the value.
4. Parameters Description
4.1 Communication Protocol
4.1.1 Communication Method
One controller to one PC: There is a special USB data cable supplied by Accuthermo. It is a
serial-to-USB data converter. While connecting a PC and the controller with this cable, the
software Accuthermo supplied will work on this setup.
Multiple controllers to one PC: By serialized multiple controllers together through the RS485 lines
(TX+/ TX-). A PC act as a master and talk to those controllers as slave units. Each controller
should have a unique ID address number. We recommend a RS485-to-USB converter act as a

Accuthermo Technology Corp. 13
communication agent between PC and controllers. The software supplied by Accuthermo cannot
talk to multiple controllers; only one at a time with proper ID address selected.
4.1.2 Communication Protocol Format
RS232/ RS485-Modbus RTU
Party None
Data bit 8 Bit
Stop bit 1 Bit
Baud rate 19200 bps
CRC16 YES
4.1.3 Communication Read/Write Format
Read Command Code: hex x03 Write Command Code: hex x06
Each time a command is sent from the master (ex. Computer) to the controller, the controller
receives should immediately response a similar message back to its master. For example:
SEND: The PC send a command set (total of 8 bytes) asking for the temperature that was just
measured: x01-03-1000-0001-CCCC
RETURN: The slave unit (controller) returned an 8-bytes data to its master:
x01-03-0002-01F7-CCCC. Where “x01F7” is the temperature measured in Hex format (=50.3 ℃ );
where “x” means hex format, “C” means CRC data.

Byte Count 1 1 bytes 2 bytes 2 bytes 2 bytes
Byte 1 – ID: It is the ID number of the controller, the default is 1.
Byte 2 – R/W Function: Read function is hex number x03, Write function is hex number x06
Byte 3,4 – Parameter Address or Return Byte Count: See the following example and description
for detail.
Byte 5,6 – Data/Data Count/Data Return Count. The 2 bytes have different meanings during the
read-send/return. For write process, the send return should have the same value.
Byte 7,8 – Modbus CRC: 16bits Cyclic Redundancy Check is done to prevent corrupted data
during communication transmission. It takes the first known command bytes through a
CRC calculation and generates the 2-CRC bytes at the end.

Accuthermo Technology Corp. 14
Write Process Example:
During the write process the response bytes should match the command set.
Master ask the controller to set the SV temperature at 55.0℃

Read Process Example:
During the read process, you can ask for one data back, or you can ask a set of data back in
sequence. The byte 3-4 is the initial parameter address. The byte 5-6 is to tell slave how many
consecutive data you want. The following example only asks for one data.
The master ask the controller to read current temperature (PV value)

In the response data set, the byte 3-4 is the byte count of the data return. The following example is
the response data from above command. The byte 3-4 tell the master it has 2 bytes of data. The
content of the return data is at byte 5-6.
