JBF6185-V6

JBF6185-V6 voltage signal sensor is a bus addressing type field device used for monitoring 6-line single phase AC voltage.
When the monitored power supply malfunctions: power interruption, overvoltage, under-voltage, fault, etc., the Voltage Signal Sensor will transmit the above fault signals to the monitor and trigger sound/light alarm signals.

Product Features
• The sensor is encoded with an electronic encoder, and the addressing range is 1 to 252.
•  The two-wire connection between the sensor and the monitor is polarity-free; both power supply and signals are transited in this BUS.
•  There are 2 indicators (LEDs) on the sensor - the green LED flashing means normal state, and the yellow light turns steady-on means fault condition.
•  The sensor monitors the voltage value of single-phase AC power supply in real time and reports all fault information (power interruption, overpressure, under-pressure, etc.) within 100 seconds.
•  The sensor can transmit the monitored voltage signal to the PWMS monitor in real time for display.

Sensor Dimensions

Wiring
a.Use encoder to write addresses to the sensors.
b.Install the sensor on the 35mm standard guide rail in the fire power distribution box.
c.Connect the non-polarity loop bus lines to the L1/L2 terminals of the sensor.
d.Terminals (1,2) are connected to (1L, 1N) AC voltage input of the monitored single-phase fire AC power supply; terminals (9,10) are connected to the (2L, 2N) AC voltage input of the monitored AC single-phase fire power supply; terminals (11,12) are connected to the (3L, 3N) AC voltage input of the monitored AC single-phase fire power supply; terminal (13, 14) are connected to the (4L, 4N) AC voltage input of the monitored AC single-phase fire power supply; terminals (15,16) are connected to the (5L, 5N) AC voltage input of the monitored AC single-phase fire power supply; terminals (17, 18) are connected to the (6L, 6N) AC voltage input of the monitored AC single-phase fire power supply;
e.Use soft twisted-pair cables for loop wire; the wire area should not be less than 1.5mm2 (RVS-2 X 1.5mm²).
f.Use copper cables for connection between the sensor and the output ends of the power supply; the wire area should not be less than 1.5mm²(BV-2x1.5mm2), for each of the pair.

Precautions
Prohibited wiring with power on.
The monitored voltage ends of different lines must be connect to the sensor one by one following the terminals order (start from terminals 1, 2); otherwise the sensor will not work properly;

Sensor Normal Display Status
When the sensor line connection is normal and the monitored voltage is normal, the sensor LCD will show the monitoring information (line1~6 information, address of the sensor) in rotating display sequence as below:

Single-phase voltage and address rotating display of the six lines

The address of the sensor in the above figure is 128.
Note: When "voltage detection input" of the sensor has a power supply interruption (or empty load), the yellow fault light will turn on and the LCD back-light will turn on. The monitor will display "power supply interruption failure" when the rotating display goes to this line number.
