5.3.2 ENGINE RUNNING
NOTE: The load transfer signal remains inactive until the generator is available. This
prevents excessive wear on the engine and alternator.
In Manual Mode , the generator does not synchronise and close its load switch unless a ‘loading
request’ is made.
A loading request can come from a number of sources.
• Press the Close Generator button.
• With Manual Breaker Control disabled, the following loading requests take effect.
o Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs.
o Activation of an auxiliary input that has been configured to Remote Start On Load or
Remote Start On Load Demand
o Request from a DSExx60 or from another DSExx10 controller over the MSC link.
o Instruction from external remote telemetry devices using the RS232, RS485 or Ethernet
interface.
Once the generator has been instructed to synchronise and placed on load, it is not automatically
removed. To instruct the generator to ramp its load off and open its load switch, ensure none of the
loading requests are active or have Manual Breaker Control enabled and either:
• Press the Open Generator
• Press the Auto Mode button to return to automatic mode. The set observes all
Auto Mode start requests and stopping timers before beginning the Auto Mode Stopping
Sequence.
• Press the Stop/Reset Mode button to remove load and stop the generator.
• Activation of an auxiliary input that has been configured to Generator Load Inhibit (no ramping
occurs).
5.3.3 STOPPING SEQUENCE
In Manual Mode the set continues to run until either:
• The Stop/Reset Mode button is pressed – The delayed load outputs are de-activated
immediately and the set immediately stops.
• The Auto Mode button is pressed. The set observes all Auto Mode start requests
and stopping timers before beginning the Auto Mode Stopping Sequence.
