Operation
The ASCO 5310 ATS Remote Annunciator communicates
with an ASCO automatic transfer switch (ATS) to report its
status. The ATS Annunciator polls the ATS and obtains its
status. Lights indicate if the ATS is connected to the normal
source or the emergency source. Source acceptability status
for the ATS is also shown. In addition, the ATS Remote
Annunciator can send commands to the ATS to control its
operation.
A control key switch prevents unauthorized operation. A
transfer test button simulates a normal source outage and
transfers the load to the emergency source, if acceptable. The
same button is used to retransfer the load back to the normal
source. When the button is held, any active time delay is
cancelled. A lights in the button indicates if the ATS is in the
test mode and if a time delay is active. See Figures 1 and 2.
