1.2 How to Install
NOTE
To install the controller, select a location where:
1. no one may accidentally touch the terminals,
150mm150mm
150mm
150mm
2. mechanical vibrations are minimal,
3. corrosive gas is minimal,
4. temperature can be maintained at about 23C and
the fluctuation is minimal,
5. no direct radiant heat is present,
6. no magnetic disturbances are caused,
7. no wind blows against the terminal board (reference junction compensation element),
8. no water is splashed,
9. no flammable materials are around,
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 150 mm away from every side;
the panels should be made of either 1.43 mm-thick metal-plated steel plates or 1.6 mm-
thick uncoated steel plates.
NOTE
Never touch the opening at the bottom of the case. It is to be used in the factory at ship-
ping.
●Installation Position
Install the controller at an angle within 30from horizontal with the front panel facing up-
ward. Do not install it facing downward. The position of right and left sides should be hori-
zontal.
Front panel

■How to Install
CAUTION
Turn off the power to the controller before installing it on the panel because there is a
possibility of electric shock.
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.

1.3 How to Connect Wires
CAUTION
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 possi-
bility of electric shock.
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.

2. Initial Settings
This chapter describes examples of setting PV input types, and control output 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
“6.1 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
SET/ENT
key for more than 3 seconds. This brings you to the display (operating
display) that appears at power-on. When you have finished configuring the initial
settings discussed in this manual, create operation programs as explained in “3.
Programming.”
Power-on
Set the alarm
type and other setup
parameters.
See “2.2 Setting PV Input Type (Setting First at Power-on),”
or “2.3 Changing PV Input Type.”
Set the control
output.
Set Program
parameters.
(Factory-set to “Time Proportional Relay Output.”)
Denotes a step that must always be followed.
(Factory-set to “Unspecified.”)
Denotes a step that should be followed as necessary.
Setup Procedure
Set operating
parameters.
Controller operation
See “2.4 Setting Control Output Type.”
See “3. Programming.”
Set PV input.

Name of Part Function
Process variable (PV) display
2. Setpoint display
•Displays PV during operation.
•Displays a parameter symbol when you set a parameter.
•Displays an error code in red if the controller fails.
•Displays such data items as the program setpoint and control output value (OUT), as
shown below, during operation.
Program setpoint
Segment number for which operation is in progress
Remaining segment time
Program setpoint at the time of hold (shown when program operation is at a pause)
Control output value
•Displays the setpoint of a parameter when it is configured.
5. Light-loader interface A communication interface for connection with an adapter cable when setting and storing
parameters from a PC. Use of this interface requires an optional parameter setting tool.
3. Status indicator lamps
Remain lit during operation.
PRG1: Program-1 operation
PRG2: Program-2 operation
HLD: Hold operation (lit when program operation is paused)
6. PRG1 and
PRG2 keys
Used to start program operation or set a program.
Operation with program pattern 1: With the operating display shown, hold down the
PRG1 key for more than 2 seconds.
Operation with program pattern 2: With the operating display shown, hold down the
PRG2 key for more than 2 seconds.
Setting of program pattern 1: With the operating parameter setting display shown,
press the PRG1 key to show the relevant program
setting parameter.
Setting of program pattern 2: With the operating parameter setting display shown,
press the PRG2 key to show the relevant program
setting parameter.
7. RESET key
Press this key for more than 2 seconds during normal operation or hold operation to
stop the operation. When stopped, the controller outputs a fixed value (preset output
value). The output is factory-set to 0.0% or OFF.
8. SET/ENT key
SET/ENT
Used to switch or register parameters. Press this key for more than 3 seconds to
alternate between the operating display and the menu for operating parameter setting
display.
Used to change numerical values. On setting displays for various parameters, you can
change the program setpoints, and parameters values. Pressing the key decreases
a numerical value, while pressing the key causes it to increase.
You can hold down either key to gradually increase the speed of change.
4. Event indicator lamps
Come on when PV event 1 or 2, or a time event occurs.
PVE1: PV event 1
PVE2: PV event 2
TME: Time event

IMPORTANT
The controller automatically returns to the display at the time of power-on (i.e., operating
display) if no key is operated for at least one minute.
