Never place the controller directly on flammable items or equipment.
If the controller has to be installed close to flammable items or equipment, be sure to provide shielding panels all around the controller, at least 150mm away from every side; the panels should be made of either 1.43mm-thick metal-plated steel plates or 1.6mm-thick uncoated steel plates.
● Installation Position
Install the controller at an angle within 30° from horizontal with the front panel facing upward. Do not install it facing downward. The position of right and left sides should be horizontal.

■ How to Install
Turn off the power to the controller before installing it on the panel because there is a possibility of electric shock.
CAUTION
After opening the mounting hole on the panel, follow the procedures below to install the controller:
1.Insert the controller into the opening from the front of the panel so that the terminal board on the rear is at the far side.
2.Set the brackets in place on the top and bottom of the controller as shown in the figure below, then tighten the screws of the brackets. Take care not to overtighten them.
Direction to insert the controller
Insert the controller into the opening at the front of the panel.
Large bracket
Panel |
(top mounting hardware) |
Terminal board
Insert a screwdriver into the brackets to tighten the screws.

1)Before carrying out wiring, turn off the power to the controller and check that the cables to be connected are not alive with a tester or the like because there is a possibility of
electric shock.
CAUTION 2) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.
NOTE
1)Provide power from a single-phase instrument power supply. If there is a lot of noise in the power line, insert an insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC2205-00U from TDK) on the secondary side.
As a countermeasures against noise, do not place the primary and secondary power cables close to each other.
2)For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires.
The cables to be used for wiring, terminal specifications, and recommended parts are as shown below.
3)Control output relays may be replaced. However, because they have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load.
4)The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load.

This chapter describes examples of setting PV input types, control output types, and alarm types. Carrying out settings described herein allows you to perform basic control. Refer to examples of various settings to understand how to set parameters required. Refer to “5.1 Parameter Map” for an easy to understand explanation of setting various parameters. If you cannot remember how to carry out an operation during setting, press the key for more than 3 seconds. This brings you to the display (operating display) that appears at power-on.
Setup Procedure

2.2Setting UT mode (Setting First at Power-on)
NOTE
The controller displays an operating display when the power is turned on. The submenu “IN” appears at this point if the type of PV input has not been defined yet. In this case, set a UT mode to “Cascade Control”, following the operating procedure described below. Then, set PV input type, control output type and others.

2.4Setting Primary and Secondary PV Input Types
The following operating prcedure describes an example of setting the primary-loop PV input type to K-type thermocouple (-200.0 to 500.0˚C) and measurement range of 0.0 to 200.0˚C.
You can take the same steps for the secondary-loop PV input type (IN3) and scale (SH3, SL3) that are displayed after the primary-loop related parameters.

6.Minimum value of PV input scale (SL1): Set the minimum value of the scale to be controlled.
NOTE
The controller may automatically initialize the registered operating parameter setpoints if any change is made to the data item PV Input Type (IN1), Maximum Value of PV Input Range (RH1), Minimum Value of PV Input Range (RL1), PV Input Decimal Point Position (DP1), Maximum Value of PV Input Scale (SH1) or Minimum Value of PV Input Scale (SL1). After a change has been made to any of these data items, be sure to verify the registered operating parameter setpoints to ensure that they are correct. If any data item has been changed to its default, set it to a required value.
