Operation
■ Settings
Motor Relay Switch Settings
Current Converter Settings
The LEDs indicate which function is in operation.
OPEN refers to open-phase, OC refers to
overcurrent, and RVS refers to reverse-phase.
Determining the Number of
Primary Conductor Runs
Determine the number of passes and the tap setting
from the table above. For example, if the current
setting range is 8 to 20 A, there is one pass and the
tap setting is 20.
Pass the wires through the holes from the same
direction. It doesn’t matter which wires go through
which holes.
Function Setting DIP SW
The reset button will pop out about 4 mm when the
relay has been tripped. After the relay has
operated, reset by pressing this button. Disconnect
the power supply before resetting for
reverse-phase operation.
The three ON/OFF switches enable or disable the
three functions. The functions can be enabled in any
combination. With the open-phase function, the H/L
switch sets the current unbalance factor. When set to
H", the motor circuit operates at 35% of the current
unbalance factor for operation. When set to L", the
motor circuit operates at 65% min. of the current
unbalance factor for operation.With the over-current
function, the x4/x1 switch sets the time changeover
value for the start-up mode. When set to x4", the
operating time range is 4 to 40 s. When set to x1",
the operating time range is 1 to 10 s.
Manual Reset
One conductor pass
(The conductors pass
through the holes once.)
Four conductor passes
(The conductors pass
through the holes four times.)
Test Button
Pushing the test button momentarily operates the trip display and
the output relay.
The operation indicators will not light for the test button. It doesn't
matter whether the function setting switch is ON or OFF.

Set the time setting knob to the required time. The operating time
is equal to the time scale value times the setting on the time
changeover switch. For example, if the time scale value is 6 and
the time changeover switch is set to 4, the operating time is 24 s.

Set the current-setting knob to the required
current value. The setting value is indicated by
the product of the scale value and the multiplying
factor as shown in the following table. The
required trip current can be obtained directly by
means of the current knob.
