... Heater elements Approximately 3 VDC Approximately 6 VDC 3 When using a K2CU which has the model number suffix ”GS” (a model that incorporates gate input terminals), the control output of the temperature controller must be a voltage output type. The signal generated by the reference voltage generator is sent to the setting circuit to provide a reference value ...

... When power is supplied to the heater (when the contactor is ON), a current flows through the wires to the heater elements. At the same time, a voltage is imposed on the power circuit of the K2CU-F. The current flowing to the heater wires is detected by the detector sections through each Current Transformer (CT) incorporated by the K2CU-F ...

... The K2CU-F’s scale is divided into 12 graduations including sub- graduations and the K2CU-P’s scale is divided into 5 graduations. The knobs of the K2CU-F and K2CU-P as shown in the illustrations are set and 0.7 A respectively. Heater Connection and Current The following table shows the different connections possible. The formula under each illustration indicates the electrical current value of the heater elements under normal and abnormal conditions ...

... K2CU (except for the K2CU-FjjA-jGS), the heater element(s) must be turned ON or OFF for longer (although the heater ele- ment(s) can be turned ON for 0.5 s according to the specifications). The K2CU cannot be used with a phase-control circuit, inverter cir- cuit, frequency-count circuit, cycle-control unit motor load. Mounting Securely mount the K2CU as horizontally as possible although there is no particular limitation of mounting directions ...
