6.6 CONTROLS
STOP/RESET
This button places the module into its
Stop/reset
mode. This will clear any alarm conditions for
which the triggering criteria have been removed. If the engine is running and this position is
selected, the module will automatically instruct the changeover device to un-load the generator
(‘Load transfer’ becomes inactive (if used))
. The fuel supply will be removed and engine will be
brought to a standstill. Should a
remote start signal
be present while operating in this mode, a
remote start will not occur.
MANUAL
This mode is used to allow manual control of the generator functions. Once in
Manual mode
the
module will respond to the start (I) button and start the engine and run off load. If the engine is
running off-load in the
Manual mode
and a
remote start signal
becomes present, the module will
automatically instruct the changeover device to place the generator on load
(‘Load transfer’
becomes active (if used))
. Should the
remote start signal
then be removed the generator will
remain on load until either the
‘STOP/RESET’
or
‘AUTO’
positions is selected.
AUTO
This button places the module into its
‘Automatic’
mode. This mode allows the module to control
the function of the generator automatically. The module will monitor the
remote start input
and
once a start condition is signalled the set will be automatically started and placed on load
(‘Load
transfer’ becomes active (if used))
. If the starting signal is removed the module will automatically
transfer the load from the generator and shut the set down observing the
stop delay timer
and
cooling timer
as necessary. The module will then await the next start event.
For further details
please see the more detailed description of ‘Auto Operation’ earlier in this manual.
TEST
This button places the module into its
‘Test’
mode. This mode allows the operator to perform an ‘on
load’ test of the system. Once in
Test mode
the module will respond to the start (I) button and start
the engine and run on load
(‘Load transfer’ becomes active (if used))
. The generator will continue
to run on load until Auto mode is selected. Then, If the starting signal is removed the module will
automatically transfer the load from the generator and shut the set down observing the
stop delay
timer
and
cooling timer
as necessary. The module will then await the next start event.
For further details please see the more detailed description of ‘Test Operation’ earlier in this manual.
START
This button is only active in MANUAL
or TEST
mode. Pressing this button in manual or
