Notice
When setting the specifications and functions of this controller, connect the terminals 1 and 2 for power
source first, then set them referring to “5. Setup” before performing “3. Mounting to control panel” and
“4. Wiring connection”.
3. Mounting to control panel
3.1 Site selection

Mountable panel thickness: Within 1 to 15mm
Insert the controller from the front side of the panel.
Attach the mounting brackets by the holes at the top and bottom of the case and secure the controller
in place with the screws.
(Fig.3.5-1)
Warning
As the case is made of resin, do not use excessive force while screwing in the
mounting bracket, or the case or screw type mounting bracket could be damaged.
The torque is approximately 0.12N•m.

4. Wiring connection
Warning
Turn the power supply to the instrument off before wiring or checking it.
Working or touching the terminal with the power switched on may result in Electric
Shock causing severe injury or death.
• The terminal block of the TP40A is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened by the
terminal screw.
• Dotted lines show options.
• Use a thermocouple and compensating lead wire according to the sensor input specification of
this controller.
• Use the 3-wire RTD which corresponds to the input specification of this controller.
• This controller does not have built-in power switch, circuit breaker or fuse. Therefore, it is
necessary to install them in the circuit near the external controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• When using a 24V AC/DC for the power source, do not confuse the polarity when it is
DC.
• When using a relay contact output type, externally use a relay according to the capacity of
the load to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load
wires to avoid external interference.
• Do not apply a commercial power source to the sensor connected to the input terminal nor
allow the power source to come into contact with the sensor.
Lead wire solderless terminal
Use a solderless terminal with isolation sleeve that fits in the M3 screw as shown below.
The torque is approximately 0.6N•m to 1.0N•m.

5. Setup
Wire the power terminals only. After the power is turned on, the sensor input characters and temperature
unit are indicated on the PV display and the input range high limit value is indicated on the SV display for
approximately 3 seconds. (Table 5-1)
(If any other value is set during the scaling high limit setting, the set value is indicated on the SV display)
During this time, all outputs and the LED indicators are in OFF status.
Control will then start and the input value will be indicated on the PV display and main setting value (SV)
will be indicated on the SV display. (While control output OFF function is working,
the PV display.)
