The
Test off Load mode will only start S2 (if configured as a generator) and leave it off load.
6.3.2.1 STARTING SEQUENCE
As soon as the MODE
‘ ’
is selected and confirmed by pressing the TICK
‘ ’
button is pressed, the output to
give a start signal to an external generator controller is activated (if S2 is configured as a generator)
If the generator fails to start during the ‘S2 Fail Delay’ timer, an alarm will appear on the display which shows
Fail to
Start. S2 is seen as available once the supply is within limits (if configured as a mains supply) or had achieved
loading voltage and frequency (if configured as a generator).
6.3.2.2 S2 AVAILABLE
In
Test off Load mode, the load is not transferred to S2 unless a ‘loading request’ is made and the S2 supply is
within limits (if configured as a mains supply) or has achieved loading voltage and frequency (if configured as a
generator).
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: NOTE: NOTE: NOTE: The load transfer signal remains inactive until The load transfer signal remains inactive until The load transfer signal remains inactive until The load transfer signal remains inactive until S2 is seen as available S2 is seen as available S2 is seen as available S2 is seen as 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 Configuration Suite Software.
See section entitled Load Shedding elsewhere in this document for further details.
