■Examples of Mode Setting

Example 1

Example 2

For the single-function SDV-FH6, the setting method given below would be used to detect overvol-

tages with a DC voltage input. The operating value is 15 V and the reset value is 12 V.

Step 1. To set the detection method and type of input on the DIP switch.

Turn OFF pin 1 (function) to specify overvoltage detection.

Turn OFF pin 2 (input) to specify a DC input.

Attach the OVER INPUT DC stickers.

Voltage multiplying factor setting: The voltage multiplying factor is selected according to the

maximum and minimum factors and a sticker is attached.

The calculation method is as follows:

The PICK UP index scale value is between 1.0 and 3.0, so calculate the voltage multiplying

factor for both 1.0 and 3.0.

15 V (Operating value)/1 (PICK UP index scale value) = 15 (Maximum multiplying factor)

15 V (Operating value)/3 (PICK UP index scale value) = 5 (Minimum multiplying factor)

In this example, pins 3 to 5 are turned OFF and the x10V sticker is attached.

PICK UP index scale value setting: The calculation method is as follows (X = index scale):

10 (Voltage multiplying factor) x X = 15 V (Operating value)

Therefore, X = 1.5

Turn the PICK UP knob to 1.5.

12 V (reset value) = 15 V (operating value) x (1 − Y) Therefore, Y = 0.2

Set the HOLD knob to 20 (%).

SDV-F@@

Step 3. To set the reset value (Y = HOLD index scale value): Calculate the HOLD percentage as

follows:

Step 2. To set the operating value according to the voltage multiplying factor and the PICK UP

index scale value.

For the single-function SDV-FH6T, the setting method given below would be used to detect undervol-

tages with a DC voltage input. The operating value is 20 V and the reset value is 20.4 V. An ON-delay

operation is specified and the setting time is 30 s.

Step 1. To set the detection method and type of input on the DIP switch.

Turn ON pin 1 (function) to specify undervoltage detection.

Turn OFF pin 2 (input) to specify a DC input.

Attach the UNDER INPUT DC stickers.

Step 2. To set the operating value according to the voltage multiplying factor and the PICK UP

index scale value.

Voltage multiplying factor setting: The multiplying factor is selected according to the maxi-

mum and minimum factors and a sticker is attached. The calculation method is as follows:

The PICK UP index scale value is between 1.0 and 3.0, so calculate the voltage multiplying

factor for both 1.0 and 3.0.

20 V (Operating value)/1 (PICK UP index scale value) = 20 (Maximum multiplying factor)

20 V (Operating value)/3 (PICK UP index scale value) = 6.7 (Minimum multiplying factor)

In this example, pins 3 to 5 are turned OFF and the x10V sticker is attached.

PICK UP index scale value setting: The calculation method is as follows (X = index scale):

10 (Voltage multiplying factor) x X = 20 V (Operating value)

Therefore, X = 2

Turn the PICK UP knob to 2.0.

Step 3. To set the reset value (Y = HOLD index scale value): Calculate the HOLD percentage as

follows:

20.4 V (reset value) = 20 V (operating value) x (1 + Y) Therefore, Y = 0.02

Set the HOLD knob to 2 (%).

Step 4. To set setting time and operating mode.

Set the time setting knob to 30 s and turn the pins 7 to 9 ON to specify ON-delay operation.

Example 3

■Shunts (Order Separately)

A shunt is a resistor to convert a DC current into a DC voltage. Use

the shunt in combination with SDV-FL to detect undercurrent, reverse

current and overcurrent in DC circuits.

Note: Select a shunt whose rated current is more than 120% of the

current normally flowing in a circuit. The characteristics of the

shunt may change or fusing of a resistor element may occur if

an overload that is 1,000% of the rated current is applied.

Therefore, determine the rated current of the shunt to be used,

by taking the circuit conditions into account.

For the dual-function SDV-DH3, the setting method given below would be used to detect over and

undervoltage with an AC voltage input. The intermediate voltage of dead band is 250 V and the dead

band voltage is 20 V.

Step 1. To set the detection method and type of input on the DIP switch.

Turn ON pin 1 (input) to specify a AC input.

Attach the OVER and UNDER INPUT AC stickers.

Step 2. To set the intermediate voltage of dead band according to the BALANCE index scale

value and the voltage multiplying factor.

Voltage multiplying factor setting: The voltage multiplying factor is selected according to the

maximum and minimum factors and a sticker is attached. The calculation method is as fol-

lows:

250 V (Intermediate voltage of dead band)/1 (BALANCE index scale value)

= 250 (maximum multiplying factor)

250 V (Intermediate voltage of dead band)/3 (BALANCE index scale value)

= 83.3 (maximum multiplying factor)

In this example, pins 2 and 3 are turned OFF and pins 4 is turned ON, and the x100V sticker

is attached.

BALANCE index scale value setting: The calculation method is as follows for the BALANCE

index scale value (X = index scale):

100 (Voltage multiplying factor) x X = 250 V (intermediate voltage of dead band)

Therefore, X = 2.5

Turn the BALANCE knob to 2.5.

Step 3. To set dead band voltage according to the voltage multiplying factor and BAND WIDTH

index scale value.

BAND WIDTH index scale value setting:

Z (BAND WIDTH index scale value) x 100 V (voltage multiplying factor) = 20 V (dead band

voltage) Therefore, Z = 0.2

Set the DEAD WIDTH knob to 0.2.

Step 4. Reset value for each detection setting: Automatically set according to the dead band

voltage setting.

Reset values are calculated for overvoltage detection and undervoltage detection.

Overvoltage detection: Reset value = (250 V + 20 V) − (20 V x 2/3) = 256.7 min.

Undervoltage detection: Reset value = (250 V − 20 V) + (20 V x 2/3) = 243.3 max.

SDV-D@@

The BALANCE index scale value is between 1.0 and 3.0, so calculate the voltage multiply-

ing factor for both 1.0 and 3.0.

■Q&A

Q: What is necessary to detect undervoltages when using the same power supply for the input voltage and the control

power supply?

A: The NO contact of the output relay is used for undervoltage detection. Even if the control voltage drops to 85% of

the rated voltage (AC power), the operation of the relay can be maintained. Set the mode setting on the DIP switch

to overvoltage detection and set the reset value to the value to be detected. Set the operating value of the SDV to

a value higher than the reset value.

Q: Will the SDV be damaged if the input setting (AC/DC) is incorrect. If not, what will happen?

A: The SDV will not be damaged, but the operating value and reset value will not be accurate. These values will be

about 10% less than the set values if DC is input for an AC setting and about 10% off to the positive side if AC is

input for a DC setting.

Q: Can the negative pole of a DC voltage be input to the SDV?

A: Yes. An absolute rectifier circuit is used in the SDV-F to enable negative pole input. The SDV-FL has a polarity

setting, which can be set to (+)(–) to disable operation with negative voltages. Positive/Negative settings cannot

be used for the dual-function SDV-D even if the intermediate voltage of dead band is set to 0. Negative inputs can-

not be used for the SDV-D.

Q: Is instantaneous detection faster than 0.5 s possible?

A: Use the S87A Power Interruption Detector for instantaneous detection (10 ms or 20 ms).

Safety Precautions

Approximately 0.5 s is required for operation. When confirming the

operating value, gradually change the input voltage while checking

the value.

Power supply voltage fluctuations and the ambient operating temper-

ature must be maintained within the allowable ranges. Be particularly

careful not to apply an overvoltage beyond the specified range for the

voltage detection.

Do not use the SDV in locations subject to corrosive or explosive

gases.

The SDV cannot be used to detect momentary power interruptions

because of its response time. Use the S87A to detect momentary

power interruptions.

An SDV cannot be used with a circuit containing thyristors, or VVVF

inverters, because these elements can change the output waveform

to the point that the SDV will malfunction.

Mounting

When mounting with the PL08 or PL15 Back Connection Socket,

insert the Socket into a 1- to 4-mm panel from the back and secure it

with screws. Do not mount the SDV until the Socket has been

mounted firmly. Be sure that the key groove on the Socket is

mounted on the bottom, and also secure the SDV to the panel with

screws.

When mounting with the 8PFA or 14PFA Back Connection Socket,

insert the SDV into the Socket and secure it with the hooks. Leave

approximately 30 mm or more between Sockets to allow enough

space for the hooks.

When mounting more than one SDV, allow at least 30 mm or more

between them.
