2. The power ON lock prevents unnecessary alarms from being generated during the
instable period when the power is first turned on. There is no relay output during timer
operation.
3. Phase loss is detected by L1, L2, and L3 voltage drops.
A phase loss will exist if any of the phases drops below 60%of the rated input.
4. L1 and L2 function both as the power supply terminals and as input terminals. If the
voltage drops dramatically, then the Relay will not operate due to an undervoltage.
5. Phase loss on the power supply or load side cannot be detected in the motor load
during operation.

lSetting Method
1. Overvoltage
The overvoltage knob (OVER) is used to set the overvoltage threshold.
The overvoltage can be set to between −30% and 25% of the rated input voltage.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the voltage.
The rated input depends on the model and DIP switch setting.
Example: K8AB-PM1 with Pin 2 Turned OFF (Three-phase, Three-wire Mode) and Pins 3 and 4 Turned OFF (Rated Voltage of 200 V)
The rated input voltage is 200 VAC and the setting range is 140 to 250 V.
2. Undervoltage
Undervoltage is set using the undervoltage knob (UNDER).
The undervoltage can be set to between −30% and 25% of the rated input.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the voltage.
The rated input depends on the model and DIP switch setting.
Example: K8AB-PM1 with Pin 2 Turned OFF (Three-phase, Three-wire Mode) and Pins 3 and 4 Turned OFF (Rated Voltage of 200 V)
The rated input voltage is 200 VAC and the setting range is 140 to 250 V.
3. Operating Time
The operating time is set using the operating time knob (T).
The operating time can be set to between 0.1 and 30 s.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the operating time.
If the input exceeds (or drops lower than) the voltage setting, the alarm indicator will start flashing for the set period and then stay lit.

Checking Operation
Overvoltages
Gradually increase the input from 80% of the setting.
The input value will equal the operating value when the
input exceeds the setting and the alarm indicator starts
flashing. Operation can be checked by the relay output that
will start after the operating time has passed.
Undervoltage
Gradually decrease the input from 120% of the setting and
check the operation using the same method as for
overvoltage.
Example: For monitoring mode set to three-phase three-wire
monitoring, a rated voltage of 200 V, and an operating time
of 5 s.
Note: K8AB-PM@output relays are normally operative.
Connection Diagram 1
How to Measure the Operating Time
Overvoltage
Change the input suddenly from 0% to 120% of the set
value and measure the time until the Unit operates.
Undervoltage
Change the input suddenly from 120% to 0% of the set
value and measure the time until the Unit operates.
Operating Time
Adjust the slide resistor so that the voltage applied to the
K8AB terminals is 120% of the set value (for overvoltage
detection) and 80% of the set value (for undervoltage
detection) when the auxiliary relay operates, as shown in
connection diagram 2. Close the switch and use the cycle
counter to measure the operating time.
Connection Diagram 2
Checking the Phase Sequence and Phase Loss
Operation
Phase Sequence
Switch the wiring, as shown by the dotted lines in
connection diagram 1, to reverse the phase sequence and
check that the K8AB operates.
Phase loss
Create a phase loss for any input phase and check that the
K8AB operates.
Operating Adjustment Knobs
Use a screwdriver to turn the knobs. There is a stopper to
prevent the knob from turning any further once it has been
turned completely to the left or right. Do not force the knob
past these limits.

10 Three-phase Phase-sequence Phase-loss Relay K8AB-PM Cat. No. N146-E1-02
Load-side Phase Loss
In principle, phase loss cannot be detected on the load side
because the K8AB-PM@measures three-phase voltage to
determine phase loss.
Motor Load Phase Loss during Operation
Motor load phase loss cannot be detected during operation.
It can be used to detect phase loss at startup.
Normally, three-phase motors will continue to rotate even if
one phase is open. The three-phase voltage will be induced
at the motor terminals. The diagram shows voltage induction
at the motor terminals when phase R has been lost with a
load applied to a three-phase motor. The horizontal axis
shows the motor load as a percentage of the rated load, and
the vertical axis shows voltage as a percentage of the rated
voltage. The lines in the graph show the voltage induced at
the motor terminals for each load phase loss occurs during
operation. As the graph shows, phase loss cannot be
detected because the motor terminal voltage does not drop
very much even if a phase is lost when the load on the motor
is light. To detect motor load phase loss during operation,
use the undervoltage detection function to detect the motor
terminal voltages at phase loss.
Set the operating time carefully because it will affect the time
from when the phase loss occurs until tripping when this
function is used.
Characteristic Curve Diagram
Note: For phase loss of phase R. VST, VTR, and VRS indicate the motor
terminal voltage at phase loss.
Overvoltage Detection When Only One Phase Exceeds
the Overvoltage Threshold
The K8AB-PM@monitors each of the three-phase voltages.
This means an overvoltage is detected if even only one
phase exceeds the threshold value. The same applies to
undervoltages.
