MROELECTRIC.COM
1-1 Features
The Heat/Cool Temperature Control Unit measures the temperature of an object
with a connected temperature sensor (thermocouple or platinum resistance
thermometer) and controls the temperature according to preset parameters.
Advanced PID Control
Stable temperature control is achieved using advanced PID control and an autotuning feature.
ON/OFF control can also be selected.
Units Available According to Type of Temperature Sensor
Two types of Temperature Control Unit are available, according to the temperature sensor used. The C200H-TV00 uses a thermocouple, and the
C200H-TV10 uses a platinum resistance thermometer.
Two Heat/Cool Control Loops with a Single Unit
Two heating and cooling control loops are possible with one Unit.
Comprehensive Output Specifications
Three types of output specification versions are available: C200H-TV1 for
transistor output, C200H-TV2 for voltage output, and C200H-TV3 for
current output.
Heater Burnout Detection
A Current Transformer (with a detection current range of 0.1 to 49.9 A and a minimum detection current difference of 2.5 A) can be connected to each of the two
control loops to facilitate rapid heater burnout detection and prompt correction of
problems.
Eight Banks of Data Settings
Eight data values such as set point (SP) and alarm set values can be preset in
eight data banks for easy selection.
Data Input and Display
The C200H-DSC01 Data Setting Console (sold separately) is used to input data
and to display process values (PV) and set values (SV).
The easy-to-read display can be panel-mounted.
User Programs Allow Reading and Writing of Data
Data can be set and retrieved by means of C200H user programs.

type of temperature sensor connected.
Do not connect different types of temperature sensors to Loop 1 and Loop 2.
2. If no input lead is connected to Loop 2, turn SW203-4 on the rear of the Unit
ON to disable Loop 2. A sensor error occurs if this switch is set to the OFF
(enabled) position when no temperature sensor is connected to Loop 2.
3. Be sure to connect (+) and (–), and (A) and (B) correctly.
4. Wire I/O leads in separate ducts from power leads to prevent noise problems.
5. A voltage of 24 VDC is used for the voltage output, current output and Data
Setting Console power supply.
6. The terminal block is removable. Make sure that it is attached correctly after
the input wiring connections are completed.

3-1 Operating Procedure
After preparing the C200H PC, follow the procedure below to use the Heat/Cool
Temperature Control Unit.
1, 2, 3...
1. Set the switches on the front and rear panels according to the operating conditions. (Refer to
Set SW2-2 under the display cover to the OFF position to enable data setting from the Data Setting Console.
2. Mount to Rack.
Turn off the C200H power supply before mounting or dismounting the
C200H on the Rack.
3. Connect the input wiring. (Refer to
The 24-VDC power supply must be connected. The Data Setting Console
will not operate unless the 24-VDC power supply is connected. The sensors
can be connected immediately before the system is tested.
4. Connect the Data Setting Console. (Refer to
Cables
5. Turn on the 24-VDC and the C200H power supplies.
Set the C200H to PROGRAM mode.
6. Use the Data Setting Console to make the settings for the parameters that
need to be changed. (Refer to the rest of this section.)
7. Test operation and adjust data. (Refer to the rest of this section.)
Connect the output wiring and turn on the heater power . To start the test op-
eration, turn ON the RUN bit of the loop that is to be controlled with a device
such as the Programming Console. Monitor the control conditions and adjust the data until the required control is achieved. During operation, the
“bank no.” is switched to “executed bank no.” and cannot be changed from
the Data Setting Console. To change it, use a device such as the Programming Console, or use the user program.
8. Create the user programs. (Refer to
Programming.
Arrange the data for the test operation, and create the user programs for
data setting, monitoring, switching the bank number, and so on. Set SW2-2
under the display cover to the ON position to enable data setting from the
C200H PC.

The read operation and setting the executed bank number are possible from a
user program or from a device, such as the Programming Console, regardless of
the ON/OFF setting of SW2-2.
Data written from the Data Setting Console and data written with write command
when SW2-1 (switching memory contents) is set to Normal are written to the
Heat/Cool Temperature Control Unit EEPROM and are consequently retained
when the power supply is turned off.
The SP value set when SW2-1 (switching memory contents) is set to Fixed and
executed bank number settings made from the C200H PC are written directly to
RAM and are not saved to EEPROM. This data is lost when the power supply is
turned off. The same data can be written to the RAM when the power is next
turned on and executes a user program. Settings made from the Programming
Console must be repeated each time the power is turned on.

The “bank no.” can be set when operation is stopped (i.e., when the RUN bit is
OFF). During operation it is switched to “executed bank no.” and cannot be
changed from the Data Setting Console. To change the executed bank number,
use a user program or a device such as the Programming Console.
Operation begins when the RUN bit of the output relay turns ON. (For information on output relays, refer to

• This sets the coefficient for finding the cooling P constant. It is valid when
SW203-1 is OFF (PID control). The formula for calculating the cooling P
constant is as follows:
Cooling P constant = heating P constant x cooling coefficient
• The I/D constant is the same for cooling as for heating.

• This sets the control period. It is valid when SW203-1 is OFF (PID control), and
only when the heater model is not the C200H-TV03 (current output type).
• Cooling loop 1 is invalid when SW203-6 is ON (current output).
• The control period is the time required to complete one transistor output or volt-

Heater Burnout Detection
Heater Burnout Detection System
The heater wiring is connected through the Current Transformer (CT). As a current flows through the heater wiring, an alternating current is induced in the CT
which is dependent on the size of the current flowing. This induced current drops
to zero if the heater burns out. The heater burnout alarm signal is output when
the induced current is compared to the set current value.
Heater Burnout Alarm Precautions
• Turn on the heater power supply and the input terminal 24-VDC power supply
at the same time as or before the C200H PC power supply. The heater burnout
signal is output if the heater power supply or the input terminal 24-VDC power
supply is turned on after the C200H PC power supply.
• Temperature Control Unit operation continues if a burned-out heater causes a
heater burnout alarm. Control signal output continues according to the control
parameters. Take measures to detect the heater burnout alarm signal to allow
early repair.
• The heater burnout alarm is output when the control output is ON. Once the
heater burnout alarm is output, it remains ON. Use one of the methods below to
reset a heater burnout alarm.
1. Turn the Special I/O Unit Restart Flag (AR0100 to AR0109) ON and then
back OFF.
2. Turn the C200H PC power supply OFF then back ON.
3. Set the heater burnout current limit to 0.0 then back to its original value.
• Make sure that the current difference between normal operation and heater
burnout is at least 2.5 A. Stable detection is difficult with a current difference
less than 2.5 A.
• Heater burnout detection is not possible with the current output type (C200HTV03) or with 3-phase heaters.
• Set the heater burnout current to 0.0 when heater burnout detection is not required because the CT input wiring is not detected.
Determining the Heater Burnout Detection Current
• Determine the SV from the following equation:
SV =
• If more than one heater is connected through the CT, take the heater burnout
current as the value when the heater with the smallest current consumption is
burned out. If all heaters consume equal current, take the heater burnout current as the value when any one heater is burned out.
• Make sure that the current difference between normal operation and heater
burnout is at least 2.5 A. Stable detection is difficult with a current difference
less than 2.5 A.
• Set the SV in the range between 0.1 A and 49.9 A. Heater burnout detection is
not carried out if the SV is set to 0.0 A or 50.0 A. The alarm signal is always OFF
if the SV is set to 0.0 or always ON if the SV is set to 50.0.
• The total heater current during normal operation should not exceed 50 A. If the
current exceeds 55.0 A, a CT Input Overflow error occurs and ffff is displayed if the heater current monitor is selected.

Example 2 Using three 200 VAC, 1 kW heaters

Burnout current with one heater burned out = x 2 = 10 A
SV = = 12.5 A (≤ 49.9 A)
