Operation
K2CU-F@@A-@GS Series
When power is supplied to the heater (when the SSR is ON), a cur-
rent flows through the wires to the heater elements. At the same
time, a voltage is imposed on the gate circuit and the K2CU-
F@@A@GS begins monitoring the current flowing through the heater
wires.
The current flowing to the heater wires is detected by the detector
sections through each Current Transformer (CT) incorporated by the
K2CU-F@@A-@GS.
The current signals transmitted by the two CTs are sent to the cur-
rent-voltage converters, smoothing circuits, and comparators as
shown in the diagram.

The signal generated by the reference voltage generator is sent to
the setting circuit to provide a reference value. The reference value
is sent to the comparators. Each comparator compares its heater
element current input and the reference value. If the input is lower
than the reference value, a signal is sent to the output circuit.
There are two detector sections operating independently. If either of
the input signals from the CTs is lower than the reference value, the
output relay and alarm indicator will be activated.
The K2CU-F@@A-@GS incorporates a voltage fluctuation compen-
sation function which automatically corrects the reference value if the
supply voltage fluctuates.
