4.1 CONTROL PUSH BUTTONS
NOTE: For further details, see section entitled Operation elsewhere in this manual.
This button places the module into its Stop/Reset Mode . This clears any
alarm conditions for which the triggering criteria have been removed. If the
generator is running on load and the module is put into Stop/Reset Mode , the
module automatically opens the generator bus breaker (‘Close Bus’ become
inactive) and instructs the DSE8x10 module to enter the return delay. Should any
form of Remote Start Signal be present while operating in this mode, a start
request to the DSE8x10 module over the MSC Link does not occur.
This button places the module into its Manual Mode .
Once in
Manual Mode ,
the module responds to the Start button to send a start
request to the DSE8x10 module over the MSC Link. The module monitors the MSC
Link for feedback from the DSE8x10 module to confirm the generator bus is
available.
If the generator bus is running off-load in the Manual Mode and a Start Signal
becomes active, the module automatically instructs the changeover device to place
the generator bus on load (‘Close Bus’ becomes active), synchronising to the
Mains if required. Upon removal of the Start On Load Signal, the generator bus
remains on load until either the Stop/Reset Mode or Auto Mode is
selected.
Also in Manual Mode ,
the module responds to the Transfer to Mains and
Transfer to Generator Bus buttons after the generator bus is available.
Synchronising occurs automatically if required.
This button places the module into its Test Mode .
Once in Test Mode ,
the module responds to the Start button to send a start request to the
DSE8x10 module over the MSC Link. The module monitors the MSC Link for
feedback from the DSE8x10 module to confirm the generator bus is available.
Once the generator bus is available, it is automatically placed on load (‘Close Bus’
becomes active), synchronising to the Mains if required. Depending upon module
configuration, the generator bus remains in constant parallel with the Mains or
proceeds to run in island operation (‘Close Mains’ becomes inactive).
The generator bus remains on load until either the Stop/Reset Mode or
Auto Mode is selected.
