SAFETY PRECAUTIONS(Be sure to read these precautions before using our products.)
The safety precautions are classified into two categories: “Warning” and “Caution”.

Caution may be linked to serious results

Depending on circumstances, procedures indicated byso be sure to follow the directions for usage.

Warning
Procedures which may lead to dangerous conditions and cause death or serious injury if not
carried out properly.

CautionProcedures which may lead to dangerous conditions and cause superficial to medium injury or
physical damage or may degrade or damage the product if not carried out properly.

21. Installation precautions(Be sure to read these precautions before using our products.)

Warning
Turn the power supply to the instrument OFF before installation.
Working or touching the terminal with the power switched ON may result in an
Electric Shock which could cause severe injury or death.

CautionSite selection
Mount the unit in a place with:(1) A minimum of dust, and an absence of corrosive gases(2) No flammable, explosive gases(3) No mechanical vibrations or shocks(4) No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )that does not change suddenly(5) An ambient non-condensing humidity of 35 to 85%RH(6) The units away from large capacity electromagnetic switches or cables
through which large current is flowing(7) No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
When mounting the case to the control panel, tighten the screw with the specified torque.
If excessive force is applied to the screw when tightening, the case may be damaged or bent.

Do not install this instrument near flammable material though the case of this instrument is made offlame resisting resin.
Avoid setting this instrument directly on flammable material.

32. Wiring precautions

Warning
Turn the power supply to the instrument OFF before wiring or checking.
Working or touching the terminal with the power switched ON may result in an
Electric Shock which could cause severe injury or death.
The instrument must be grounded before the power supply to the instrument
is turned on.

Caution• Do not put wire chips into the instrument, because they could cause fire, malfunction or trouble.
• For the DC power source wiring, do not confuse the polarity as described in this instruction
manual.
• For the CMT-220-K ground terminal, use a wire whose thickness is 2mm2 or greater.
However, avoid grounding in conjunction with the power line.
• Use the solderless terminal with insulation sleeve that fits to the M3 screw when wiring
the CMT-220-K terminals.
• Tighten the terminal screw within the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may be damaged.
• It is advised to provide the protective device against such environmental conditions as may
cause damage to the device or contribute to the deterioration of its parts.

3. Running and maintenance precautions

Warning• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn off the power before cleaning the module or retightening the screws.
Doing this work while the power is on may result in an electric shock which could cause
severe injury or death.

CMT-220-K cannot be applied to the Heating/Cooling, DC voltage and DC current input specificationsof the CPT-20A, but can be applied to the other functions of the CPT-20A as well as all functions of
the CPT-20A

1. Overview
1.1 Overview of CMT-220-K
CMT-220-K reads and writes data of up to 10 units (20 points of temperature control) of the 2-channel
temperature control unit (CCT-235) via 1 unit of the C series power source host link unit (CPT-200).
1.2 Units and structure of CMT-220-K(1) Touch panel monitoring unit
CMT-220-K: Touch panel monitoring unit to communicate with the CPT-200(2) Power source host link unit
CPT-200: Link unit to supply the power to the CCT-235 and to communicate
with the CMT-220-K(3) 2-channel temperature control unit
CCT-235-2/: Independent temperature control unit with 2 channels of which
input or output types are the same(4) Base unit
CBT-210: Base unit for mounting the CPT-200 and CCT-235

h Proportional cycle setting display

Sets the proportional cycle for all channels.
Setting range: 1 to 120 seconds

h Sensor correction setting display
Sets the sensor correction value for all channels.
When a sensor cannot be set at a location where control
is desired, the sensor measuring temperature may deviate
from the temperature in the controlled location. The control

Loop break alarm
The alarm will be activated when the process variable (PV) does not rise as much as the spanor greater within the time it takes to assess the loop break alarm after the manipulated variable
has reached 100% or the output high limit value.
The alarm will also be activated when the process variable (PV) does not fall as much value
as the span or greater within the time it takes to assess loop break alarm after the manipulating
value has reached 0% or the output low limit value.
For the cooling control output, read “fall” for “rise” and vice versa.
h Heating/Cooling action selection display
Selects Heating or Cooling action for all channels.

TROUBLESHOOTING

CMT-220-K

7. Troubleshooting
If any malfunctions occur, check if the power is supplied to the CMT-220-K and C series.
When the power is supplied to the C series, the green LED of Power (PW) indicator lights up.
Check the following when C series does not work even if its indicator lights up.

Warning
Turn the power supply to the instrument OFF before wiring or checking.
Working or touching the terminal with the power switched on may result in an
Electric Shock which could cause severe injury or death.

Phenomenon: The control output of CMT-220-K cannot be turned on. (The temperature does not rise.)Presumed cause
Solution
The setting value has not been set yet.

Set the setting value from the CMT-220-K (P. 25)
Turn the control output on from the CMT-220-K(P. 26).
Set the control output high limit value properly
from the CMT-220-K (P. 30).

Control output status has been turned off.
Control output high limit value is set to 0%.

Phenomenon: Control output of the CMT-220-K is not turned off. (The temperature rises too much.)

Presumed cause
Temperature unit setting is mistaken.

SolutionSet the unit properly from the CMT-220-K. (P. 29)
Set the value properly from the CMT-220-K.
(P. 28)

Improper sensor correction value is set.
Phenomenon: It is unable to set from the CMT-220-K.
Presumed cause
Auto-tuning is performing.

Solution
Cancel the auto-tuning (P. 26).

Phenomenon: It is unable to communicate. (“Serial COM Error” is indicated on the display.)
Presumed cause
SolutionSet the same transfer rate to both. (P. 13, 14)
Data transfer rates of CMT-220-K and CPT-200 do
not concur.
Wiring of the communication cable is mistaken.

Wire the cable properly (P. 11).
