K8DT-PM

DIP Switch Settings

The Power ON lock time, rated voltage are set using the DIP switch located on the front of the Unit.
K8DT-PM

@

 does not use SW2.

Note:

Open the DIP switch cover to set the DIP switch.
Keep the DIP switch cover closed while the power supply to the Relay is ON.

Setting Methods

Overvoltage

The overvoltage knob (OVER) is used to set the overvoltage threshold.
The overvoltage can be set to between 

30% and 30% 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 the DIP switch setting.
Example:  K8DT-PM1 with DIP Switch Set to 200 V

The rated input is 200 VAC and the setting range is 140 to 250 V.

Undervoltage

Undervoltage is set using the undervoltage knob (UNDR).
The undervoltage can be set to between 

30% and 30% 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 the rotary switch setting.
Example:  K8DT-PM1 with Rotary Switch Set to 200 V

The rated input voltage is 200 VAC and the setting range is 140 to 250 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.
