Operating Instructions Temperature Indicating Controller CF1M

To prevent accidents arising from the use of this controller, please ensure the operator using it receives this
manual.

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 Electric Shock,
which can cause severe injury or death.

3. Operation

PV/SV display indicates the characters of the sensor type and temperature unit for approx.
2 seconds after the power is turned on. During this time, all outputs and the LED indicators are
in their off status. (Refer to table 3.1-1 and 3.1-2.)
After that, actual temperature or the main setting value is indicated, and control starts.
(If PV display is selected in PV/SV display selection, the actual temperature will be indicated.
If SV display is selected, the main setting value will be indicated.)

Sensor correction function

Corrects the input value from the sensor. 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. When controlling with plural controllers,
the accuracy of sensors affects the control.
Therefore, sometimes the measuring temperature (input value) does not concur with the
same setting value. In such a case, the control can be set with the desired temperature
by shifting the input value of sensors.

Loop break alarm

After the manipulating value has reached 100% or output high limit value, if the process variable (PV)
has not risen at least as high as the span value by the time it takes to assess the loop break alarm,
the alarm will be activated.
After the manipulating value has reached 0% or output low limit value, if the process variable (PV)
has not fallen at least as low as the value of the span within the time it takes to assess the loop break
alarm, the alarm will also be activated.
When the control action is Direct (Cooling), the alarm acts conversely.

Energized/Deenergized

When the status of temperature alarm action is selected energized, event output
(between terminal 11 and 12) is conducted (ON) status while the event output
indicator is lit. Event output is not conducted (OFF) status while the event output
indicator is not lit.
When the status of temperature alarm action is selected deenergized, event output
(between terminal 11 and 12) is not conducted (OFF) status while the event output
indicator is lit. Event output is conducted (ON) status while the event output
indicator is not lit.

After the completion of the mounting to the control panel and wiring connections,
start running in the following manner.

(1) Turn the power supplied to the CF1M ON

For approx. 2 seconds after the power is switched ON, the type of sensor is indicated on the
PV/SV display. (Refer to table 3.1-1 and 3.1-2.)
During this time, all outputs and LED indicators are in their OFF status.
After that, the PV/SV display indicates actual temperature.

If SV display is selected in PV/SV display change, the setting value will be indicated.

(2) Input the setting value

Referring to Chapter 3. Operation, input each setting value.

When the thermocouple or RTD is burnt out or the input value rises to the [Rated scale maximum
value + 50°C (100°F)] or greater, the control output is turned off, and [

[Downscale]

In the case of thermocouple input, if the input value falls to -50°C (-100°F) or less, the control output
is turned off, and [ ] blinks on the PV/SV display.

In the case of RTD input, if the input value falls to the [Rated scale minimum value - 1% of rated

(2) Self-diagnostic function

The CPU is monitored by a watchdog timer, and when any abnormal status is found on the CPU,
the controller is switched to warm-up status.

(3) Automatic cold junction temperature compensation (thermocouple input type)

Detects the temperature at the connection terminal between thermocouple and instrument,

Notices

• Use a thermocouple and compensating lead wire according to the input specifications of this
controller.

• Use a 3-wire system of RTD according to the input specifications of this controller.

• This controller has no built-in power switch nor fuse. It is necessary to install them manually
(IEC approved, 100Vac 5A, 220Vac 5A) in the circuit near the external controller.

• In the case of 24Vdc, do not confuse the polarity.

• With the relay contact output type, use an external auxiliary electromagnetic switch to protect
the built-in relay contact.

• When wiring, keep input wire (Thermocouple, RTD, etc.) away from AC source and load wire
to avoid external interference.

n Recommended terminal
Use a solderless terminal with an insulation sleeve that fits to M3 screw as shown below.

9. Troubleshooting

When troubled, refer to the following items after checking the power and the wiring.

<Indication>

Phenomenon Presumed cause and the action

If PV/SV display is
indicating [ ]

If [ ] is blinking
on the PV/SV display

• Control output OFF function is working.
Press the

OUT

/

key for approx. 1s to release the function.

OFF

• Thermocouple or RTD is burnt out.
[In the case of Thermocouple]

If the input terminal of the instrument is connected,
and if nearby room temperature is indicated, the instrument
should be normal and sensor may be burnout.

[In the case of RTD]

If approx. 100Ω of resistance is connected to the input terminal
between A-B of the instrument and between B-B is connected,
and if nearby 0°C (32°F) is indicated, the instrument should
be normal and sensor may be burnout.

• Lead wire of thermocouple or RTD is not surely mounted to the
instrument terminal.

If [ ] is blinking
on the PV/SV display

If indication of
PV/SV display is
abnormal or unstable.

• Polarity of thermocouple or compensating lead wire is reverse.

• Codes (A, B, B) of RTD does not agree with the instrument terminal.

• Designation of the Sensor input is improper.

• Temperature unit (°C or °F) is mistaken.

• Sensor correcting value is unsuitable.

Set the value suitably.

• Specification of the Thermocouple or RTD is improper.

• AC leaks into thermocouple or RTD circuit.

• There is a piece of equipment to send out inductive interference

or noise near the controller.
