Use the potentiometer on the front panel to set the operating cur-
rent.
Rotate the knob to set the desired current value at which the Heater
Burnout Detector should operate. Do not exceed the maximum and
minimum positions.
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 to 32 A and 0.7 A respectively.
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.
Note: Values in this table are correct when a 200 VAC, 1 kW heater is used on a single-phase or three-phase current.
