Precautions
K2CU-F@@A-@GS
Use the K2CU-F@@A-@GS (with gate input terminals) in combina-
tion with a temperature controller that has PID with feed-forward cir-
cuitry to control the heater temperature, in which case, the heater
element(s) must be turned ON or OFF for 0.1 s or longer.
K2CU-F
When a single-phase heater is used, pass the two lines through the
openings of the heater burnout detector. When a three-phase heater
is used, pass two (phases) of the three lines through the openings. In
either case, if only one line passes through, an alarm signal will
always be produced.
Pass the lines through the openings only once. If they are passed
more than once, the actual operating current will be less than the set
current. The lines can be passed in either direction.
To use the heater burnout detector at a current less than the current
range that can be set, the lines must be passed more than once.
Determine the number of times the lines should be passed by the fol-
lowing equation:
(Operating current) x n = Current setting range
where,
n: number of times the lines loop through the window
All K2CU-F models incorporate a voltage fluctuation compensation
function.
Operating Current Setting when Several Heaters are Used
The following table shows relative values of changes in the current when any one of several heaters connected in parallel has burned out. The
current value under normal condition is 1. Use this table as a guideline in determining the operating current.
Note: 1. This table shows the respective change rates in current when any one of several heaters connected in parallel has burned out.

2. The current value under the normal condition is 1.
3. The values in this table are logical values. Actually, these values may vary slightly because of influence of unbalanced loads (heaters). It
is therefore recommended to test the actual current values and the load condition before determining the operating current, especially
when the current under the normal condition and that under an abnormal condition do not significantly differ.

K2CU
K2CU-P
The K2CU-P can be used only in single-phase circuits.
Do not pull out the K2CU-P from the socket when the K2CU-P is
energized. Especially when using it in combination with a Current
Transformer commercially available, this practice causes the second-
ary circuit of the transformer to open, which is very dangerous.
General
Refer to “External Connections” before using the K2CU with external
CTs.
When a temperature controller is used in combination with the K2CU
(except for the K2CU-F@@A-@GS), the heater element(s) must be
turned ON or OFF for 1 s or longer (although the heater element(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, or a motor load.
Mounting
Securely mount the K2CU as horizontally as possible although there
is no particular limitation of mounting directions.
Connection
Solderless-type terminal must be connected to the terminals
securely.
Wire the terminals correctly by referring to the external connections.
The terminals have no polarity. Be sure to connect 100 (or 110) V to
the 100-V (or 110-V) terminals and 200 (or 220) V to the 200-V (or
220-V) terminals of the K2CU-P or the K2CU-P may malfunction.
The control power source for the K2CU (except for the K2CU-F@@A-
@GS) must be supplied from the load side via a contactor.
Be sure to impose a voltage between the 0-V terminal and 100-V (or
110-V) terminal or the 0-V terminal and 200-V (or 220-V) terminal of
the K2CU-P, otherwise the K2CU-P will not operate.
