SAFETY INFORMATION
Before using, please read this (SAFETY INFORMATION) and then use this controller.
It is important that the instructions in this manual are followed when using this instrument.
Please keep this manual for future reference.
Precautions are classified in WARNING and CAUTION.
WARNING There is a possibility of death or heavy injury when handling in wrong way.
CAUTION
There is a possibility of injury or physical damage when handling in wrong way.
WARNING
● Attach the brackets (2 units) on the fixed halls and tighten with a screwdriver.
Fixing torque is about 147N. cm (1.5kg.cm)
(Care should be taken not to tighten forcedly)
③ Caution on terminal connections
●
●
●
●
●
Caution on wiring
● Use an external protection circuit if a fault in the control loop could possibly lead to a
serious problem.
● This instrument do not have a switch for power and a fuse, so please set them if it is needed.
●
●
(Fuse rating 250V, 0.5A)
Power supply
● Use a rated voltage to prevent damage or trouble.
● To avoid electrical shock or damage, do not turn ON the power until the wiring is
completed.
Prohibit use in gas atmosphere
●
●
●
To avoid induction noise to input wires seperate from the power and output wires.
Keep input wires away from output wires and use shielded wires to earth.
Use a compensating cable with thermocouple.
For R.T.D input use a cable which is a small lead wire resistance and without resistance
difference to 3 wires.
If the wiring has noise, use the following step: connect a surge absorber to the conductor
coil side if the conductors are connected to the load output, such as the relay contact output.
(EX. For AC 220V ENC 471D-05A)
Use an insulating transformer with a noise filter when the power suppy has much noise.
(EX. TDK brand ZMB 22R5-11 noise filter)
Noise filter should be mounted on a panel which has been earthed and the wiring between
the noise filter output and the instrument power terminals should be shorten.
It is effective to use a twisted cable for power supply against noise.
The heater power supply and the instrument power supply should be connected using the
same power suppy when a heater break alarm.
Time for preparation of contact output is required at power ON. When the output signal is
used for an extenal interlock circuit, connect a delay relay.
Do not use it at a place exposed to combustible or explosive gas.
④ For load circuit connection
Handling of unit
● Use an extra relay when the frequency of operation is rather high.
SSR output type is recommended.
• Electromagnetic switch : Proportional cycle time is Min. 30sec
• SSR : Proportional cycle time is Min. 1 sec
• Contact output life : Mechanical : 10 million times (no load)
Electrical : 100 thousand times (rated load)
• SSR drive pulse voltage, DC 4~20mA are not insulated with internal circuit.
Use non-grounded sensor to R.T.D and thermocouple.
● To avoid malfunction, electrical shock or fire, this unit must not be disassembled or
repaired.
● Do not touch the terminals to avoid electrical shock or malfunction.
Caution on maintenance
● Turn OFF the power before mounting or removing the instrument.
● To ensure continuous and safe operation of the instrument, periodical maintenance is
recommended. Some parts are limited in life.
● The warranty period is 1 year only if using in the correct way.
CAUTION
Caution on handling
Do not install the instrument under any of the following conditions.
●
●
●
●
●
●
●
●
●
The ambient temperature exceeds 0 ~ 50℃
The ambient humidity exceeds 45 ~ 85%RH.
A place where temperature changes suddenly or icing occurs.
A place exposed to corrosive gas or combustible gas.
Vibration or shock is likely to be transmitted to the instrument.
A place exposed to water, oil, chemicals, steam, sunlight.
A place exposed to much dust, salt or iron.
A place with much inductive disturbance, static electricity, magnetism noise.
A place where heat such as radiant heat stays.

⑤ For waterproof (Waterproof type)
The instrument has IP65. Use rubber packing when installing the instrument to panel.
Please attach the rubber in correct way.
⑥ Caution on key operation / trouble
● If alarm function is not set correctly, alarm output can not be operated at a trouble point.
Be sure to check the alarm operation.
● If the input cable is disconnected, the display shows“
”.
When replacing the sensor, please turn OFF the power suppy.
⑦ Other
Do not use organic solvents such as alcohol, benzine when cleaning. (Use neutral detergent)

OUTPUT GROUP SETTING
● Type of control output (Heating / Cooling type )
This process controller is divided into 2 types: UNIVERSAL TYPE AND HEATING / COOLING
TYPE. Output is selectable from Relay, SSR, and Current (4~20mA DC).
Output type range (output code) is ~ for universal type and ~⑫ for Heating /Cooling type.
Sometimes retransmission output and alarm output are not available according to control output
(EX. When you choose output code (OT) 2, it is current output of Universal type. In this case,
retransmission output and alarm output are available. But, In Heating / Cooling control type with
SSR on Heating side and Relay output on Cooling side (output code ⑩), the retransmission output
is avalable but alarm output 3 is not available.
