When used in conjunction with a Voltage Dip-Proofing Inverter or a Voltage Dip Compensator and Bypass switch, it may be used to prove the effectiveness of the DPI or VDC as a solution for these power quality problems. The PCOSS incorporates a Soak Test function selected via the Function Select menu, that may be used to perform repetitive testing. The PSCOC is designed for 120/208/240Vac operation. The main controls and their functions are listed below, refer to Fig 7 page 12 for their locations :1. The sag level set by an external variac or transformer ( the sag source ) is indicated on the LCD display. 2. A variable interrupt timer that is used to set the duration and Interval of the voltage sag. Both parameters are set using the programming keys and indicated on the LCD display. Refer to the menu flow chart and programming key function table in Fig 3 p6 for Sag Simulation and Fig 4 p9 for Soak Test. Operation Sag Simulation Follow the steps outlined below to set up and operate the PSCOS. Refer to Fig 3 on page 6 for information on menu layout and programming key functions. 1. Connect the supply, external Sag Source, Voltage Dip-Proofing Inverter or Voltage Dip Compensator, Bypass Switch and load to the PSCOS; see Fig 8 page 13. 2. Set the sag source to zero output and the Bypass Switch to Inverter Bypassed. 3. Switch on the power to the PSCOS; the display will show: DIP-PROOFING TECHNOLOGIES INC. SAG SIMULATOR AND SOAK TESTER SELF TEST PASSED! FUNCTION SELECT 1 SAG SIMULATOR 2 SOAK TEST Note: If an error message is displayed and the Simulator shuts down please refer to Error conditions at the end of this section on page 8. 4. Press the key to reach the Sag Simulator menu; the display will show: SAG SIMULATOR 1 START TEST 2 SET PARAMETERS 5. Press the key to reach the Start Test display; the display will show: Programmable Static Change Over Switch Page 3 User Manual START TEST VOLTAGE: DURATION: 000Vac 0.100s 6. The Sag Depth may be adjusted using the an external variac prior to performing the test. The value is shown on the Voltage readout. In this case a preset value is used for the Sag Duration (100ms). The simulator will store the value used for the last test and use it as the default for the next test. 7. Press thekey to Start Test or press thekey to return to the Sag Simulator menu. 8. To set the Sag Parameters to values different to the defaults navigate to the Sag Simulator menu, press the key to select Set Parameters then press the key to reach the adjustment menus. The Sag Depth is set using the external variac and then the interrupt timer should be programmed to set the duration of the voltage sag to be generated. The two parameters are adjusted as follows :8.1 Set Sag Depth: At the Set Sag Depth Menu press the key to reach the Adjust Variac menu. Adjust the external variac until desired voltage is indicated on the display. If a tapped transformer is used as a sag source connect the desired tap. 8.2 Set Sag Duration: From the Set Sag Depth menu press key to select the Set Sag Duration menu. Press thekey to program the Sag Duration value. Use theandkeys to select the digit to adjust. The active digit will flash. Use the keys to increment or decrement the digit to the desired value. 9. Start Test: When the Sag Voltage and Duration have been set navigate back to the Sag Simulator menu by pressing the key. Press thekey to reach the Start Test menu. At this point the variac may be used to readjust the sag voltage. The voltage setting will be indicated on the display. The supply voltage can be interrupted by pressing thekey. The effect of the programmed sag can be seen on the unprotected load; one or more contactors or relays will drop out. The sag profile can be observed using a power monitor or an oscilloscope if these are available. The simulation can be tried with various settings (sag depth and duration) as often as desired to pinpoint sensitive components in the control system. 10. Test with DPI or VDC in circuit: The Bypass Switch should now be set to Inverter in Circuit and the sag simulations repeated to evaluate the effectiveness of using the Voltage Dip-Proofing Inverter or Voltage Dip Compensator to harden the controls against momentary sags and interruptions. Page 4 Programmable Static Change Over Switch User Manual 11. Sync pulse output: A synchronization pulse is available at terminals 5 & 6. This pulse may be used to trigger an oscilloscope in order to display the sag profile. The output remains at zero volts until a sag is initiated at which time the output rises to 5 volts and remains at this level until the end of the sag duration period. The output then returns to zero volts. The sync pulse output is electrically isolated. Programmable Static Change Over Switch Page 5 Page 6 SYSTEM FAILURE!
