General
Model R35/R36 is a digital indicating controller featuring
multi-range inputs and PID control system using new
algorithms "RationaLOOP PID (Ra-PID)" and "Just-FiTTER".
Up to two control output points (this number of points may
vary depending on the model) can be used, which are
selectable from the relay contact, motor drive relay, and
current.
Features
•
Space saving design with a depth of 65mm.
The mask of the front panel is also only 5mm thick.
•
High accuracy of ±0.1% FS and sampling cycle of 0.1
seconds.
•
The controller is applicable to the communication (3-wire
RS-485) as optional.
•
Multi-range inputs are available for selection, where the
input type can be freely changed among RTD, current,
and voltage.
•
The control output types (relay, motor drive relay, and
current) can be combined by using the control outputs 1
and 2.
•
The control method can be selected from any of the
ON/OFF control and PID control using "RationaLOOP
PID (Ra-PID) + Just-FiTTER".
•
Event 3 points or 2 points (independent contact), CT
input 2 points, DI 4 points, RSP inputs, and RS-485 can
be combined to select.
•
The heat/cool control is achieved by using two control
output points and event outputs.

• Setting items
• Main setting: MV (Manipulated variable)
• Sub-setting: Change in PV from the point that the MV exceeds the main setting.
• ON delay time: Diagnosis time
• Operation specifications
The event is turned ON when the MV exceeding the main setting is held (conditions 2) and the PV
does not reach the value that the sub-setting is added to (subtracted from) the PV at the point where
the MV exceeds the main setting within the diagnosis time (ON delay time) (conditions 1).
• CAUTION

Event type
Loop diagnosis 3
The event is turned ON when PV does not change corresponding to increase/decrease in MV
(Manipulated variable).
This event is used to detect any fault of final control devices.
• Setting items
• Main setting: Change in PV from the point that the MV reaches the high limit (100%) or low limit (0%).
• Sub-setting: Range of absolute value of deviation (PV – SP) allowing the event to turn OFF.
• ON delay time: Diagnosis time
• OFF delay time: A period of time from power ON allowing the event to turn OFF.
• Operation specifications
• The direct action is used for the heat control. The event is turned ON when the increase in PV
becomes smaller than the main setting after the diagnosis time (ON delay time) has elapsed from the
time that the MV had reached the high limit, or when the decrease in PV becomes smaller than the
main setting from the time that the diagnosis time (ON delay time) has elapsed from the time that the
MV had reached the low limit.
• The reverse action is used for the cool control. The event is turned ON when the decrease in PV
becomes smaller than the main setting after the diagnosis time (ON delay time) has elapsed from the
time that the MV had reached the high limit, or when the increase in PV becomes smaller than the
main setting after the diagnosis time (ON delay time) has elapsed from the time that the MV had
reached the low limit.
• The event is turned OFF regardless of other conditions when the absolute value of the deviation (PV
- SP) becomes less than the sub-setting.
• The event is turned OFF regardless of other conditions when a period of time after starting of
operation from the time that the power has been turned ON becomes less than the OFF delay time.
However, the event is turned OFF when the absolute value of the deviation is the (sub-setting –
hysteresis) value or less after the absolute value of the deviation has become the sub-setting or
more.
• CAUTION
When setting the ON delay and OFF delay, it is necessary to put in "Multi-function setup".
The default settings of the ON delay and OFF delay before shipment are 0.0s.

Timer (status)
The direct and reverse action settings are disabled for the timer event.
When using the timer event, it is necessary to set the operation type of the DI allocation to "Timer
Start/Stop". Additionally, by setting the event channel of the DI allocation, multiple timer events are
controlled from individual internal contacts (DI).
• Setting items
• ON delay time: A period of time necessary to change the event from OFF to ON after DI has been
changed from OFF to ON.
• OFF delay time: A period of time necessary to change the event from ON to OFF after DI has been
changed from ON to OFF.
• Operation specifications
• The event is turned ON when DI ON continues for ON delay time or longer.
• The event is turned OFF when DI OFF continues for OFF delay time or longer.
• In other cases, the current status is continued.
• CAUTION
When setting the ON delay and OFF delay, it is necessary to put in "Multi-function setup".
The default settings of the ON delay and OFF delay before shipment are 0.0s.
The default setting of the event channel of the DI allocation before shipment is "0". In this case, the
timer event start/stop can be set for all internal events from one internal contact (DI).
Additionally, as one or more event channel is set, the timer event start/stop can be set for one internal
event specified by one internal contact (DI).
Note that, for setting the event channel of the DI allocation, it is necessary to put in "Multi-function
setup".
Direct/Reverse action, standby, and READY operations can be set while each event (E1.C1 to E5.C2) is
set up.

3. Noise sources in the installation environment and
preventive measures
Precautions on the Use of Self-tuning Function
The final control devices must be turned on
simultaneously with or prior to this product when the
self-tuning function is to be used.
Generally, the following may be the noise sources in the
installation environment:
Relay and contact, electromagnetic coil, solenoid valve,
power supply line (particularly, 100 V AC or more), motor
commutator, phase angle control SCR, radio
communication device, welding machine, high-voltage
ignitor, etc.
Precautions on Wiring
1. Internal isolation
Solid line portions "⎯⎯" are isolated.
Dotted line portions "------" are not isolated.

4. Wiring precautions
(1) After taking the noise preventive measures, do not
bundle the primary and secondary power cables
together or put both power cables in the same conduit or
duct.
Notes:
∗
Availability of input and output is based on a model.
∗
For independent contacts, event outputs 1 and 2 are isolated.
(2) Keep the input/output and communication lines 50 cm or
more away from the power lines and power supply lines
having a voltage of 100 V AC or more.
Additionally, do not put these lines together in the same
conduit or duct.
2. Preventive measures against noise for power supply
(1) Reduction of noise
Even though the noise is small, the noise filter is used to
eliminate the effect of the noise as much as possible.
5. Inspection after wiring
After the wiring work has been completed, always
inspect and check the wiring status. Great care should
be taken since incorrect wiring may cause the product to
malfunction or severe personal injury.
(2) Protection from large noise
If a large amount of noise exists, use appropriate
isolation transformer and line filter to eliminate the effect
of the noise.
