Description
Stop / Reset
This button places the module into its
Stop / Reset
mode. This clears any
alarm conditions for which the triggering criteria have been removed. If S2 is on
load and the module is placed into Stop mode, the module automatically instructs
the changeover device to unload the S2 source (
Close S2 Output
becomes
inactive (if used)). If S2 is configured for a generator, the start signal given to the
generator controller is also removed. If a
Remote Start
signal is present while
operating in this mode, the remote start does not occur.
IMPORTANT NOTE:
If S1 is available, it will connect the load to source S1.
Manual
This button places the module into its
Manual
mode to allow manual control of
the ATS functions. This starts S2 when configured as a generator and runs it off
load.
Auto
This button places the module into its
Auto
mode. This mode allows the
module to control the function of S1 and S2 automatically. The module monitors
the
remote start
input and S1 supply status and once a start request is made, a
start request is given to S2 if configured to a generator and once available, placed
on load.
Upon removal of the starting signal, the module automatically transfers the load
from S2 and remove the start signal to the generator observing the
return delay
timer and
cooling
timer as necessary. The module then waits for the next start
event.
Mode
This button allows the user to cycle through different operating
Mode
and
press the
button to accept the mode change.
The modes available are:
Test On Load:
This mode allows the module to start and load S2 for test purposes.
Test Off Load:
This mode allows the module to start S2 and leave off load for test
purposes.
Prohibit Return:
This mode is used to prevent the module from returning load the
S1 until instructed.
