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. SDV-F@@ Turn OFF pin 2 (input) to specify a DC input. Attach the OVER 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 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. Step 3. To set the reset value (Y = HOLD index scale value): Calculate the HOLD percentage as follows: 12 V (reset value) = 15 V (operating value) x (1 − Y) Therefore, Y = 0.2 Set the HOLD knob to 20 (%). Example 2 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. SDV-FH@T 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. 11 SDV Example 3 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. SDV-D@@ 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: 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. 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. ■ Shunts (Order Separately) Characteristics SDV-SH5A (Rated Current: 5 A) 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 rated at 60 mV shunt may change or fusing of a resistor element may occur if an overload that is 1,000% of the rated current is applied. 60 Therefore, determine the rated current of the shunt to be used, by taking the circuit conditions into account. 5 Input current (A) 12 Output voltage (mV) SDV ■ Application Example Current Detection Using the Shunt (SDV-FL) Overload Detection (B) Overload Detection (A) (+) (−) SDV-SH DC power SDV-SH Power shunt supply for or M _ shunt supply distribution board DC motor (−) (+) (−) SDV-FL SDV-FL (with or without polarity) (without polarity) (+) Example: Overload detection in equipment such as a motor in a Example: Overload detection in a distribution switch rolling mill when the polarity of the applied voltage to board installed in a power substation. the motor is reversed.

SDV-F (undervoltage detection) 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?

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. S87A Power Interruption Detector 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.
