This input is used to prevent the unit from loading the Source 1 supply. If the Source 1 supply is already on load,
activating this input will cause the unit to unload the Source 1 supply. Removing the input will allow the Source 1
to be loaded again.
This input only operates to control the Source 1-switching device if the unit load
switching logic is attempting to load the Source 1. It will not control the Source 1-switching device when the
Source 2 is on load.
When module in the AUTO mode. In the event of a remote start or soruce failure, the other source will be
instructed to start and take load. On removal of the remote start signal or source with the higher priority return,
the module will continue to supply the load until this AUTO RESTORE INHIBIT input is removed. Once the input
is removed the unit will transfer the load back to the source with the higher priority. This input allows the module
to be fitted as part of a system where the manual restoration to source is controlled remotely or by an automated
system.
This input is used to provide an over-ride function to prevent the unit from starting the generator in the event of a
remote start or source failure condition occurring. If this input is active and a remote start signal or source failure
occurs the unit will not give a start command to the generator. If this input signal is then removed, the unit will
operate as if a remote start or source failure has occurred, starting and loading the generator. This function can
be used to give an 'AND' function so that a generator will only be called to start if the source fails and another
condition exists whish requires the generator to run. If the 'Auto Start Inhibit' signal become active once more it
will be ignored until the unit has returned the source supply on load and shutdown.
This input is used to provide security to the installation. If the panel lock input is active, the unit will not respond to
operation of the mode select or start buttons. This allows the unit to be placed into a spesific mode (such as
Auto) and than secured. The operation of the unit is not affected and the operator will still be able to view the
various instrumentation pages etc.
External control sources (i.e. Simulate Start Button) are not affected by
the panel lock input and will continue to operate normally.
This input is used to prevent the generator for starting in the event of a programmed scheduled (exercise) run
occurring. While the input is active no scheduled runs will occur. If the input is active when a schedule run is
called for, and is removed during the running period the gen-set will start and complete any remaining scheduled
running time.
This input is used to transfer the load to the source 2 when running in Manual mode.
This input is used to transfer the load to the source 1 when running in Manual mode.
In AUTO mode, if one of the configurable inputs are selected as 22 (Remote Inhibit) and this input is active, the
module will inhibit the generator for starting. In the other hand, if this input is active while the generator was
starting, the module will stop the generator.
Allows an Auto Start module to instruct the ATS unit that the system is available to take load. The ATS unit then
monitors the voltage and frequency to check they are within acceptable limits before performing the load transfer
function.
