Description - Programmable Static Change Over Switch (PSCOS)
The PSCOS is intended to be used as a tool to evaluate the effects of momentary
voltage sags and interruptions on industrial controls. 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:

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.

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.

Description
Where no-break maintenance is required a by pass switch must be installed. It
connects the supply directly to the load, "Bypass" position, and disconnects the power
terminals of the inverter without interrupting the supply. When in "DPI" position the load is
connected to the supply via the inverter.
