6 Operation Monitor Operation: When the input voltage parameters are normal, the "Contacts Transferred" LED will be on and relay is energized. Once the unit has responded to a fault by releasing the output relay and simultaneously extinguishing the "Contacts Transferred" LED, the nature of the fault that caused the release will be identified by one of the four fault status indicators. In the automatic reset mode, the status indicator will extinguish and the "Contacts Transferred" LED will re-light once all faults are corrected and restart delay period has expired. In the manual reset mode, the fault indicator will flash when all faults have been corrected, thus indicating that the unit is ready for manual reset. When manually reset, the flashing fault status indicator will extinguish and the "Contacts Transferred" LED will relight. Series PMA has a fixed start-up delay of approximately 375 milliseconds. Series PMB has a start-up delay, adjustable from 0 to 5 minutes, which permits staggered restarting of motors, etc., affected by a common power outage. If the unit is wired for manual reset, the external reset switch must also be opened. The output relay will remain in the transferred state until one of the fault conditions occur. (See Figures 1 and 2) AGASTAT Phase Loss Condition: If the voltage of any phase drops below 68% of the nominal voltage setting for more than two line cycles, the output relay will release. If back EMF accompanies the loss of a phase, the unit will sense the loss as a phase imbalance and the relay will drop out. Figure 1 Phase Reversal Condition: If any two phases become reversed for more than two line cycles, the output relay will release. Undervoltage Condition: By strapping, the user can select one of four undervoltage thresholds: 10%, 14%, 17% or 20% below the nominal voltage, which is entered by means of a calibrated potentiometer located on the front panel. When the average voltage drops below the selected threshold, a time delay shown in Fig. 1 is initiated. The unit then continues to monitor the severity of the fault and modifies the time delay accordingly. If the undervoltage condition persists, the time delay will expire and the output relay will release. Phase Imbalance Condition: The unit continuously averages the three phase voltages and recognizes individual deviations from the average. By strapping, the user can select one of four imbalance thresholds: Either 2.0%, 3.0%, 3.5%, 4.0%, or 5.0%, 7.0%, 8.5%, 10.0% depending on model. When any phase voltage deviates more than the selected percentage from the three phase average, a time delay as shown in Fig. 2 is initiated. The unit then continues to monitor the severity of the fault and modifies the time delay accordingly. If the phase imbalance condition persists, the time delay will expire and the output relay will release.

7 SDAS-01 series 1.5 To 15 Amp AC Current Sensor Zero insertion loss Inductive coupling to power line Choice of modes Adjustable overcurrent sensor Adjustable undercurrent sensor Solid state sensing circuit 1 Form C (SPDT) or 2 Form C (DPDT) internal relay P&B Users should thoroughly review the technical data before selecting a product part number. It is recommended that user also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. Sensing Modes Overcurrent sensor Detects a current in excess of the value determined by the potentiometer setting. A built-in time delay, 200 ms, minimum, allows for normal starting and surge currents. Actual time delay is dependent upon potentiometer setting and magnitude of overcurrent. Any overcurrent lasting longer than this causes the internal relay of the SDAS- 01 to energize. The relay will remain energized until sensor control voltage is removed, even if the overcurrent ceases to exist. Undercurrent sensor Reacts to a complete loss of sense current, or any current of less than the potentiometer setting. Upon application of sensor control voltage, there is a nominal 350ms delay during which time power line current must begin. This delay gives line components time to turn on. If, at the end of the delay, sense current should decrease to less than the potentiometer setting of the SDAS-01 and remain there for approximately 350 ms, the internal relay of the SDAS-01 will energize. It will remain energized until either sense control current again exceeds the potentiometer setting, or until sensor control voltage is removed.

9 WD25 Operation WD25 paralleling relays are used to ensure that two circuits are synchronized. When voltage, phase relationship and frequency are within the selected synchronizing limits, the output relay will energize. The WD25 paralleling relay allows for a generator to be brought online without damage or system disturbance. WD25 series with a "dead bus" feature will energize for a synchronized condition or an "on line" generator, "dead bus" condition. This "dead bus" feature allows the generator to energize a dead bus. The "double dead bus" feature permits paralleling of two buses when: (a) both the line voltages are equal and in phase, or (b) when either bus is "hot" and the other bus is "dead."

10 KILOVAC WD2759 Over/Undervoltage Relays Function 27/59 ANSI/IEEE C WD2759 Operation WD2759 AC voltage sensing relays provide voltage monitoring and protection in AC systems from 50 to 400 Hz. Sensing voltages, number of phases, over and undervoltage setpoint, and time delays are user configured. WD2759 voltage relays operate when the externally adjustable trip point is reached. An external time delay control is provided with an adjustment of.5 to 10 seconds. This time delay may be used to prevent false tripping when there are slight variations in the voltage supply. On overvoltage (OV) the output relay energizes when the input signal exceeds the trip point. On undervoltage (UV) the output relay de-energizes when the input signal goes below the trip point. A green LED indicates power to the relay. Red LED lights indicate the state of the undervoltage and overvoltage trips. WD2759 Specifications Nominal Operating Range: 120, 208, 277 or 480 VAC, selectable. Maximum Sensing Range: 700VAC. Nominal Frequency Range: Hz.

NOTE: for the Reverse Power (WD32-00X) a resistive load must be used and for the Reverse KVAR (WD32-01X) an inductive load must be used. 4. Slowly adjust the TRIP SET control CCW until the relay trips. 5. Remove the applied Current and set the TIME DELAY control to the desired time delay. 6. Re-apply the Current (10% more than the trip current) to the relay and measure the time to trip. 7. Adjust the TIME DELAY and repeat steps 4 and 5 until you have the desired time delay.

12 WD47 Operation WD47 phase sequence relays are designed to monitor the correct phase rotation and loss of phase of three phase ac systems from 50 to 400 Hz. An incorrect phase sequence or loss of any phase will cause the WD47 to pickup. When the phase sequence is corrected or the lost phase is restored the contacts dropout. Red LED's light to indicate a fault condition. A green LED indicates power to the relay. The WD47 is often used to detect reverse phase rotation or loss of phase to generators, busses, motors, and transformers. Catalog WD47 Phase Sequence Relays Function 47 ANSI/IEEE C KILOVAC WD47 Calibration The WD47 has no adjustments and no calibration is necessary. Proper operation may be verified as follows: 1. Apply a nominal, three-phase input with the correct phase sequence. The output relay should dropout and the green LED should light. 2. Apply a nominal, three-phase input with an incorrect phase sequence. The output relay should pickup and the red LED should light. 3. Apply only one or two phases with the correct phase sequence. The output relay should pickup and the red LED should light. WD47 Specifications Nominal Operating Range: 120 to 480 VAC. Maximum Sensing Range: 575VAC. Nominal Frequency Range: Hz.

13 WD5051 1Ø and 3Ø Overcurrent Relays Function 5051 KILOVAC WD5051 Operation WD5051 AC current sensing relays provide current monitoring and protection in AC systems from 50 to 400 Hz. Nominal Sensing Current, Instantaneous Over Current setpoint, Time Over Current setpoint, and Time Over Current time delay are user configured. WD5051 current relays operate when the externally adjustable trip point is reached. An external time over current time delay control is provided with an adjustment of.5 to 20 seconds. This time delay may be used to prevent false tripping when there are slight variations in the sensed current. With control power applied, the Instantaneous Over Current (IOC) contacts pick-up when the input signal exceeds the IOC trip setpoint. Similarly, with control power applied, the Time Over Current (TOC) contacts pick-up after the preset time delay when the Sense Current rises above the TOC trip setpoint. The IOC contacts may also be configured to function as an under current relay. A green LED indicates power to the relay. Red LED lights indicate the state of the IOC and TOC trips.
