Page 8: System Overview
2 System Overview 2.1 Description A Static Transfer Switch (STS) provides seamless switching between two power sources to provide interrupted power to a critical load. The STS continuously monitors the supply sources for failure or degeneration and switches automatically to the alternate source if the load will be affected. The break in the supply transition is so short that it is not seen by the critical load. -

6.2 Connecting to the Web Server To use a ping test to confirm the connection on a PC, run command prompt (CMD) and type ping (space) then the IP address of the device then press enter. Entering the IP address into the web browser address bar brings up the web server home page. If the DHCP / address have not yet been registered on your network you may need to remove the cable for 5 to 10 seconds and reconnect the cable, this in turn should re-register the device on the network. -

A lock out results after this but is re-set on a new fault alarm condition. A setting of “0” inhibits retries and device will not transfer back to the preferred source. NOTE: Adjustment may be required to the Transient values if the source supply voltages are distorted or above or below nominal.

Page 37: Maintenance Bypass
7 Maintenance Bypass 7.1 Overview Maintenance bypass mode allows the load to be connected to one supply without going through the power circuit of the STS. In this mode, transferring the load to an alternate supply is not possible. The maintenance bypass mode should only be used to select the presently operating source. -

4. Finally OPEN Q3 (The STS is now isolated from the output but the critical load is supplied from the Maintenance Bypass via Q4). Bypass to Supply 2 1. Use the TRANSFER pushbutton to transfer the load to the desired source (Supply 2). 2. - Page 39 9. Use the TRANSFER pushbutton on the front control panel to select the desired source. Check and ensure that this corresponds to the PREFERRED source selection, (located above the OVERRIDE switch). 10. Check that the LCD display and mimic correctly reflect the state of the system and that the ALARM LED is off.

Page 42: Load Fault
8.2 Load Fault In case of sustained high current output load faults, the STS will inhibit a transfer to the alternate supply even if this means degradation or loss of source supply. It is therefore imperative that you ensure that the discrimination with downstream and upstream protective devices ensures that the downstream protective device always clears the fault first. -

• Inspect cable / plug connections for overheating. • Units with fans need their fans changed every 3-5 years. This may need to be sooner if the environment is bad. Please contact Static Power for help with troubleshooting and parts replacement. -
