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 d uplicated SPE system) and reports
the result. If the position of the switch in a sing le SPE cabinet or EPN cabinet, or
switches in a duplic ated SPE cabinet, is such that the system software c an
control Emergency Transfer (auto), then the test passes. If the posi tion of the
switch or switches is suc h that the system software cannot control Emergenc y
Transfer (manu al “o n” o r manu al “o ff”) , then the te st fai ls. In the PPN t he SYSAM
controls Emergency Transfer, and in the EPN, the EPN Maintenance circuit pac k
controls Emergency Transfer
