Determine the current scale multiplying factor corresponding to the
current SV range obtained from Table 1 and paste the current scale
multiplying decal to the motor protective relay. For example, when
the current setting range is 8 to 20 A, the decal no. is 2.
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.
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.
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
