DSE Model 7000 Series Control & Instrumentation System Operators Manual
Part No. 057-074 7000 Series OPERATING MANUAL ISSUE 2 02/05/2008 ADM
61
Display Reason
OIL PRESSURE SENSOR OPEN
CIRCUIT The oil pressure sensor is detected as not being present (open circuit)
AUXILIARY INPUTS
An active auxiliary input configured as a shutdown will cause the engine to
shut down. The display shows the text as configured by the user.
LOSS OF SPEED SIGNAL The speed signal from the magnetic pickup is not being received by the
DSE controller.
ECU DATA FAIL The module is configured for CAN operation and does not detect data on
the engine Can datalink, the engine shuts down.
ECU SHUTDOWN The engine ECU has detected a shutdown alarm and has informed the
DSE module of this situation. The exact error is also indicated on the
module’s display.
kW OVERLOAD The measured Total kW is above the setting of the kW overload shutdown
alarm
NEGATIVE PHASE SEQUENCE
(DSE7000 series V2.0.0 or above
only) Indicates ‘out of balance’ current loading of the generator.
Sometimes also called Negative Sequence Current or Symmetry Fault
8.5 HIGH CURRENT SHUTDOWN ALARM
GENERATOR HIGH CURRENT, if the module detects a generator output current in excess of the adjustable trip a
warning alarm occurs. This warning will continue for a period depending upon the level of overload placed on the
generator, and the configuration setting for Generator High Current in the 7000 series configuration software.
For instance, the factory default settings for Generator High Current allow for a loading of the generator to 110% for
one hour. That is to say if the generator load level exceeds the trip point by 10%, a warning alarm will occur while
the overload condition exists. If the load level does not drop to normal levels within one hour, the set stops, with the
7000 series module displaying either a shutdown or electrical trip alarm depending upon module configuration.
High current shutdown is a latching alarm and stops the Generator. Remove the fault then press Stop/Reset to
reset the module.
NOTE:- Higher overload levels will result in a faster acting shutdown condition. For instance with the
factory default configuration, an overload level twice that of the trip level (typically 200%) will result in a
Generator High Current shutdown condition after 36 seconds.
For details of the relationship between the overload and the shutdown time, please see the Appendix
section of this manual.
