■ Setting of Operating Current
Use the potentiometer on the front panel to set the operating current.
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.
■ 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.
Note: Values in this table are correct when a 200 VAC, 1 kW heater is used on a single-phase or three-phase current.

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 set operating current is defined as the mean value of the heater
current under normal operating conditions and the heater current
under a burnout or abnormal condition.
