Note:
When one or more TPS unit resides in a system sharing a common “0V” with any other type
power supply (SPS/RPS/XPS), jumper only one of the TPS units to enable Earth Fault
Detection. All other power supplies must be jumpered to disable Earth Fault Detection.
Ensure that the Slave Exec firmware, later than Revision 1.04, is loaded on this TPS.
The TPS device address is set via DIP switch SW1, which is a bank of eight switches. From left to
right (see figure below), these switches are designated as SW1-1 through SW1-8. The function of
these switches is as follows:
SW1-1.
This switch sets the baud rate for the internal FACP communications line running between
the card and the FACP CPU. Set this switch to ON.
SW1-2 through SW1-8.
These switches set the card’s address within the FACP.
Note:
You must set these switches to the value assigned to the card by the Programmer.
