4.10.3.3 S2 AVAILABLE
In Prohibit Return mode, the load is automatically transferred to S2 when it is within limits (if
configured as a mains supply) or has achieved Loading Voltage and Loading Frequency (if configured
as a generator).
If a start/load request is present but S2 does not go on load, an input configured to ‘S2 Load Inhibit’
could be active.
A loading request can come from a number of sources.
• S1 supply out of limits
• Activation of an auxiliary input that has been configured to Remote Start On Load
• Activation of the inbuilt exercise scheduler if configured for ‘on load’ runs.
NOTE: The load transfer signal remains inactive until S2 is seen as available. This
prevents loading to a supply that has failed or is not yet available.
As the load increases and decreases, the module may (depending upon configuration) remove non-
essential loads. This is configured as part of the Load Shedding control settings in the DSE
Configuration Suite Software.
See section entitled Load Shedding elsewhere in this document for further details.
If all start/load requests are removed, the Stopping sequence begins.
4.10.3.4 STOPPING SEQUENCE
In Return Inhibit mode, S2 continues to run on load even if S1 has return until either:
• Pressing the Start Inhibit button to return to start inhibit mode.
• Pressing the Auto button to return to automatic mode.
