■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■ HOT INSERTION/REMOVAL OF MODULES
Removing or replacing modules does not affect other modules on the same backplane. It is possible to replace them
without removing the power supply. However, replacing
multiple modules at once may greatly change line voltage
levels. We recommend that you replace them one by one.
■ ENVIRONMENT
•Indoor use
•When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ventilation.
•Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
•Environmental temperature must be within -10 to +55°C (14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ WIRING
•Do not install cables (power supply, input and output)
close to noise sources (relay drive cable, high frequency
line, etc.).
•Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

INSTALLATION
Use the Installation Base (model: R3-BSx).
■ UNUSED INPUT CHANNELS
•Unused channels can be specified and set so on the PC
Configurator Software (model: R3CON) without needing
to short at the field terminals.
■ AND ....
•The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

■ SETTING EXAMPLE 2: HEATER WIRE BREAK
In addition to the setting example 1 configuration, the heater’s wire break can be detected using a CT input. Suppose that the
heater has 100V / 1kW rating, driven by an SSR.
(1)Current flowing through the heater is calculated in the equation: 1kW / 100V = 10A. Choose the current sensor model
CLSE-05, for the maximum of 50A rating. Connect the sensor to CT input 1 as in the figure below.

■ SETTING EXAMPLE 3: SWITCHING SETPOINT VALUE BY EVENT INPUT
The Controller has two discrete inputs for event control input.
At the maximum of four sets of temperature setpoints and PID parameters can be predefined and stored in the ‘banks.’ The
external event input can be used to switch among these banks.
In this example, the Controller is set according to the example 1 for the setpoint 40.0°C. By using banks, an additional setting
to switch the setpoint to 50.0°C by an event input is created.
(1)Connect a switch to the discrete input 1 as shown below.

UNIVERSAL INPUT
The Controller has two universal inputs (universal input 1, universal input 2) which can be assigned independently for temperature inputs. In addition to RTD and thermocouples, resistor, DC and potentiometer inputs are also usable. The resistor,
DC and potentiometer input is scaled into a temperature range.
Universal input 1 is usually assigned as PV input signal for loop 1, while universal input 2 is for loop 2. Universal input 2
signal can be cascaded into the loop 1 SP.

• Standard PID Control
Typical PID control operation is performed by PID1 P (proportional band), PID1 I (integral time) and PID1 D (derivative time) set in the selected bank. The Controller automatically adjusts the heating control output (MV) to match the setpoint value
(SP) with the universal input value (PV).
• Heating-Cooling PID Control
PID control is applied to both heating and cooling using PID parameters in PID1 (for heating) and PID2 (for cooling) parameters.

changes in PV and SP.
• Heating-Cooling ON/OFF Control
The control output is turned on until the universal input (PV) matches the setpoint value (SP) and then turned off. Heating
control is applied when the SP is greater than the PV, while cooling control is applied when the SP is smaller than the PV. The output is turned on again if the PV is deviated from the SP again, but the sensitivity to react to a deviation can be set for
heating and cooling respectively.

n DIRECT/REVERSE ACTION
Direct or reverse action can be specified for the standard PID control.
Choose ‘reverse’ action when the MV should be decreased with an increasing PV (typical heating control), and ‘direct’ action
when the MV should be increased (typical cooling control).
Disregarded if the selected control strategy is other than the standard PID control.

Standby sequence is a function to prevent unwanted alarm triggered at the startup or at an SP change. If the PV is in alarm
range at the startup or at an SP change, no alarm is triggered until the PV is out of the range. Once it is out and then in the
range again, normal alarm function starts functioning.

For the deviation alarm, specify offset values from the SP (positive value for a temperature value greater than the SP, negative value for one smaller).
For the absolute value alarm, specify absolute temperature values.
• ALARM HYSTERESIS
Hysteresis, a deadband between ON point and OFF point, is used to prevent frequent ON/OFF operations (generally called

The Controller has four sets of banks per loop. Temperature setpoint and PID and other parameters can be stored and
switched easily during operation by an external event input (Di) or via Modbus communication.
Bank 0 is used when there is no bank switching.

Specify local SP.
CAUTION
Local SP bank is saved in the nonvolatile memory of the device.
If the SP bank is changed frequently during operation, the memory may reach its limit of writing, approx. 106 cycles

n DEADBAND
Deadband is a zone in which neither heating nor cooling control is performed.
Negative value setting means both heating and cooling control is performed in the zone.
The figure below shows an example of ON/OFF control with the deadband set to 10°C.

At PID control, deadband is enabled for P control. At P control (I = 0 and D = 0.0), with continuous value control, a zone in
which both heating MV and cooling MV equal 0 is formed at ±5°C of the SP when the deadband is set to 10°C. With the setting to -10°C, the zone is with both heating MV and cooling MV.
• Deadband set to 10°C (at I=0, D=0.0)

n MANUAL RESET
Manual reset is used to eliminate errors by offset generated by P control (I = 0, D = 0.0) or PD control (I = 0).
MV (control output) changes from 100% to 0% proportionally to the temperature range set with P value. The MV is converted
so that the MV set with the manual reset value is equal to the SP.
The figure below shows an example of MV value transition against PV when SP is set to 50.0°C, the manual reset value to
40.00%, with P (proportional-only) control (P = 10.0, I = 0, D = 0.0).

n HEATER WIRE BREAK ALARM / SSR SHORTCIRCUIT FAILURE ALARM / OVERLOAD ALARM
The following three types of alarm are available using the CT inputs.
These alarms could be used independently or in combination.
For example, with a heater driven by an SSR, the heater wire break, the SSR shortcircuit failure and the overload can be all
detected and alerted.
Heater wire break alarm
SSR shortcircuit failure

Overload alarm
CAUTION
Current flows through the load normally when
control output ON
the control output is on. Current stops when the
control output OFF
heater’s wire breaks.
heater current
The Controller measures the current with a clampon current sensor and triggers an alarm when it is
measuring current
below the setpoint.
Current stop normally when the control output is off. Current flows through the load when
the SSR fails in the shortcircuit mode.
The Controller measures the current with a clamp-on current sensor and triggers an alarm
when it is above the setpoint.
Regardless of the control status, the Controller continuously measures the current with a
clamp-on current sensor and triggers an alarm when it is above the setpoint.
Control output must be turned on for at the minimum of 110 milliseconds to detect a heater wire break; must be
turned off for at the minimum of 200 milliseconds to detect an SSR shortcircuit failure. If there is no ON and/or OFF
status longer than the minimum duration for one control cycle, the Controller cannot measure current. Current display shows -0.1A (invalid measurement) and all related alarms are reset except for those latched.
