Warning
Turn the power supplied to the instrument OFF before wiring or checking it.
Working or touching the terminal with the power switched ON may result in Electric
Shock causing severe injury or death.
Caution
• Do not leave wire chips into the CS4R when wiring, because they could cause fire, malfunction
and trouble.
• Insert the connecting cable into the designated connector securely. Not doing so could cause
malfunction due to imperfect contact.
• Connect the AC power to the designated terminal as is written in this instruction manual.
Otherwise it may burn and damage the CS4R.
• Do not apply a commercial power source to the sensor connected to the input terminal nor allow
the power source to come into contact with the sensor.
• When using a 24V AC/DC for the power source, do not confuse the polarity when it is DC.
• This unit does not have built-in power switch, circuit breaker or fuse. Therfore it is necessary to
install them in the circuit near the external unit.
(Recommended fuse: Time-lag fuse, Rated voltage 250V AC, Rated current 2A)
• Tighten the terminal scre w with the specified torque. Excessive force could damage the terminal
screw and deform the case.
• Use a thermocouple and compensating lead wire that corresponds to the sensor input specification of
this unit.
• Use the 3-wire RTD that corresponds to the sensor input specification of this unit.
• When using DC voltage and current inputs, be careful not to confuse the polarity when wiring.
• Keep input wires (Thermocouple, RTD, etc.) away from power source and load wires when wiring.

Sensor correction function
This 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 multiple controllers,
the accuracy of the sensors or dispersion of load capacity has influence on the control.
Therefore, sometimes the measured temperature (input value) does not concur with the same setting
value. In such case the control can be set at the desired temperature by correcting the input value of
the sensors.
Loop break alarm
The alarm will be activated when the process variable (PV) does not rise as much value as the span or
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 the Loop
break alarm after the manipulated variable has reached 0% or the output low limit value.
When the control action is Direct (Cooling), the alarm acts conversely.

6. Converter function
Caution
• When using this controller as a converter, take 1 second into consideration since input/output
response time is approx. 1 second.
• When switching from converter function to controller function, the control parameter and values
set by converter function are held even if the function is switched to controller function.
So, correct the control parameter and values which has been set by converter function to the
values necessary for the controller function after switching to the controller function.
The converter function of this instrument converts each input value (thermocouple, RTD, DC voltage and
DC current inputs) to “4 ... 20mA DC” using the control parameter of the controller, and outputs it.
When this instrument is used as a converter, follow steps (1) to (7) described below.
After steps (1) to (7) are finished, this instrument can be used as a converter.
(1) Wire this controller (Power supply, Input and Output).
(2) Turn the power of this controller ON.
