6.2 CONTROL PUSH-BUTTONS
Description Button
Start Inhibit/Reset
This button places the module into its
‘
START INHIBIT/RESET
’
mode. This
will clear 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
will automatically instruct the changeover device to unload S2 (‘Close S2
Output’ becomes inactive (if used)). If S2 is configured for a generator, the start
signal given to the generator controller will also be removed. Should a remote
start signal be present while operating in this mode, a remote start will not
occur.
Manual
This button places the module into its
‘
MANUAL
’
mode to allow manual
control of the ATS functions. This will start S2 if configured as a generator, and
run it off load.
If the S2 is available off-load in the
‘
MANUAL
’
mode and a remote start
on load signal becomes present, the module will automatically instruct the
changeover device to place S2 on load (‘Close S2 Output’ becomes active (if
used)). Upon removal of the remote start signal, S2 remains on load until
either selection of the
‘
START INHIBIT/RESET
’
or
‘
AUTO
’
modes.
For further details, please see the more detailed description of ‘Manual
operation’ elsewhere in this manual.
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 will
monitor the remote start input and S1 supply status and once a start request is
made, a start request will be given to S2 if configured to a generator and once
available, placed on load.
Upon removal of the starting signal, the module will automatically transfer the
load from S2 and remove the start signal to the generator 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’
elsewhere in this manual.
Mode
This button allows the user to cycle through different operating
‘
MODE
’
and
press the TICK
‘ ’
to accept the mode change.
The modes available are:
Test On Load: This mode allows the module start and load S2 for test
purposes.
Test Off Load: This mode allows the module 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.
For further details, please see the more detailed description of ‘Mode operation’
elsewhere in this manual.
