correctly.
●Power Supply
Connect the power supply to terminals A1 and A2.
●Outputs
AL1 (SPDT relay) is output to terminals 11, 12, and 14.
AL2 (SPDT relay) is output to terminals 21, 22, and 24.
Note: Use the recommended ferrules if using twisted wires.
DIP Switch Settings
The power ON lock time, resetting method and operating mode are set using the DIP switch located on the bottom of the Unit.

Setting Method
●Setting Voltage
The voltage knob (AL1 and AL2) is used to set the voltage.
The voltage can be set to 10% to 100% of the maximum setting
range.
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 maximum setting range will differ depending on the model and
the input terminal.
Example: K8AK-VW3 Using Input Terminal V3-COM
The maximum setting range will be 600 VAC/VDC and the setting
range will be 60 to 600 V.
●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.
If the input exceeds (or drops lower than) the voltage set value, 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 set value.
The input will equal the operating value when the input
exceeds the set value and the alarm indicator starts flashing.
Operation can be checked by the relay outputs that will start
after the operating time has passed.
Undervoltage
Gradually decrease the input from 120% of the set value and
check the operation using the same method as for
overvoltage.
Example: Overvoltage Operating Mode, Undervoltage Operating
Mode and an Operating Time of 5 s
Note: K8AK-VW@output relays are normally operative.
Connection Diagram
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.
Setting the Pre-alarm Monitoring Mode
Use the DIP switch to set the operating mode pins both to
overvoltage (SW3 ON and SW4 OFF) or both to undervoltage
(SW3 OFF and SW4 ON).
Example: Both Pins Set to Overvoltage
AL1 can be used as the pre-alarm for AL2 by setting a
smaller voltage set value for AL1 than for AL2.
