Application Software - 5418-6350 D
—Released Nov, 2014
Software Modifications:
1. Changed Gain Breakpoint #2 to the same variable as #1.
2. Modified the 50 Hz./ 60 Hz function so that a Discrete Input does not have to
be used when used with 50 Hz.
3. Added a Start Fuel Limit 2 feature. This allows a second breakpoint based on
speed, for easier start up of slow speed engines.
4. Optimized the GAP for Rate Group Structure. Only two rate groups are
available, 5 ms and 80 ms. This increases available internal RAM.
5. Added a delay in the Load Pulse function, so that when the breaker closes,
the Load Pulse function does not activate.
6. Removed the Auxiliary Analog Input option. This was no longer needed as the
Synchronizer Input does the same feature, and was confusing.
7. Removed the Discrete Output Test option. This was not supposed to be an
option to the user. It is only an internal setting.
8. Added a Precise Frequency Control option to help islanded systems keep
their clocks closer in time.
9. Added a way of disabling the Instant Ramp to Synchronous speed. There was
a field issue which was giving a Raise / Lower command to the ramp after the
breaker was closed, and on occasion would instantly ramp to the Raise Limit.
10. Added an Inhibit switch in the Breaker Open logic. A field issue was seen
where the frequency of the system was lower than synchronous speed and
the load would not come down to the Unload Setpoint. An operator would
manually have to open the breaker if this were Inhibited.

Software Modifications:
1. Fixed issue with Idle Speed Reference. When 50 Hz was selected the Idle
Speed was not selected.
2. Fixed Analog Input selector to correctly select the External Load Sensor and
the MAP Limiter Input. This was broken in revision D.
3. Added Generator Breaker Open Pulse logic. When enabled, and the
generator breaker opens and the load is greater than a load percentage will
cut back on the Fuel Demand to the engine for a specific time. This helps
prevent over speed on the engine.

—Released January, 2016
Software Modifications:
1. Analog input #1, Low Value was changed from a 0.0 to 1.0
2. Changed the logic for the Data Log. The Data Log would never stop logging,
therefore you could not print it out.
3. Added some logic in the Frequency Control to reset the Integrator.
4. Added a reset to the Real Time Clock (RTC). Also added logic to run the
RTC only when the engine is running.
5. Changed the logic in the Second Dynamics section. Customer could not use
the First Dynamics when isolated and the Second Dynamics when tied to the
mains. First Dynamics can now be used when the CB Aux is closed, Second
Dynamics can be selected with CB Aux or Second Dynamics Discrete Input.
6. Added logic to allow user to not have to select the Idle / Rated Discrete Input
in order to get the engine to rated speed. If the user does not need the
engine to start at idle speed, they only need to de-select the Idle / Rated
Discrete Input and the speed reference will be at Rated.
