channels. The output relay status will automatically return to its controlled state when the user
leaves the output relay test mode.
Note:
The front panel alarm LED’s will not indicate relay status in the output relay test mode.
CAUTION:
Alarms that are connected to a remote alarm monitor will send false ‘nuisance’ alarm
status if toggled while in the output relay test mode.
Warning:
Turning the control relays for Equalize or HVSD on in the test mode will result in the
power plant entering that mode. The power plant rectifiers will be shutdown if the
HVSD output relay is turned on; the rectifiers will also be shut down if the test “ALL”
relays option is used. If the power plant has been commissioned use extreme caution
when testing these relays to make sure that power plant operation will not be adversely
affected.
The output relay test mode can be very useful during the power plant test and acceptance to verify
operation. Rectifier response to Equalize, HVSD, and Restart can be checked. External audible or
visual monitors can be tested. Alarm call outs can be verified, etc.
