Notice

 

• 

The terminal block of the KT4 Series 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) 

• 

For a 24V AC/DC power source, do not confuse polarity when using direct current (DC). 

• 

When using a relay contact output type, 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. 

• 

If A2 and Heater burnout alarm are applied together, they share common output terminals. 

 

Lead wire solderless terminal 

Use a solderless terminal with an insulation sleeve in which an M3 screw fits as shown below. 

The torque is approximately 0.6N•m to 1.0N•m.

Option: Heater burnout alarm

 

(1) 

This alarm is not usable for detecting heater current

 

under phase control. 

(2) 

This alarm is not usable for

 

detecting 3-phase 

heater current.

 

(3) Use the current transformer (CT) provided, and pass one 

lead wire of the heater circuit into the hole of the CT. 

(4) When wiring, keep CT wire away from AC sources 

or load wires to avoid the external interference.
