Emergency Transfer Query Test (#124)
The Emergency Transfer Query Test queries the hardware for the state of the
Emergency Transfer switch (or switches in a duplicated SPE system) and reports
the result. If the position of the switch in a single SPE cabinet or EPN cabinet, or
switches in a duplicated SPE cabinet, is such that the system software can
control Emergency Transfer (auto), then the test passes. If the position of the
switch or switches is such that the system software cannot control Emergency
Transfer (manual “on” or manual “off”), then the test fails. In the PPN the SYSAM
controls Emergency Transfer, and in the EPN, the EPN Maintenance circuit pack
controls Emergency Transfer
