15 AUTO RESTORE INHIBIT
16 AUTO START INHIBIT
18 SCHEDULED RUNS(EXERCISE) INHIBITED
23 ENGINE RUNNING
When module in the AUTO mode. In the event of a remote start or mains failure, the generator will be instructed
to start and take load. On removal of the remote start signal or mains return, the module will continue to run the
generator on load until this AUTO RESTORE INHIBIT input is removed. Once the input is removed the unit will
transfer the load back to the mains supply and follow a normal generator stop sequence. This input allows the
module to be fitted as part of a system where the manual restoration to mains 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 mains out of limits condition occurring. If this input is active and a remote start signal or mains
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 mains 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 mains 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 mains supply on load and shutdown.
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.
If one of the configurable inputs are selected as Engine Running and this input is active, the Engine Running
LED lights on.

22 REMOTE INHIBIT
24 GENERATOR READY
25 EMERGENCY STOP
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.
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.
This input is used as the emergency stop input.

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
