DSE Model 4110 AutoStart Operators Manual
8 057-022 4110 OPERATING MANUAL ISSUE 5.1 18/06/2007 JR
4 PROTECTIONS
The module will indicate that an alarm has occurred by illuminating the relevant LED.
4.1 WARNINGS
Warnings are used to warn the operator of an impending fault
BATTERY CHARGE FAILURE, if the module does not detect a voltage from the warning light terminal on the
auxiliary charge alternator, the
icon will illuminate. (Either 8 Volts or 16 Volts depending on the configuration
of Nominal DC Voltage).
Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant icon will be illuminated when the input is
active
4.2 SHUTDOWNS
Shutdowns are latching and stop the generator. The alarm must be cleared and the fault removed to reset the
module. In the event of a shutdown the appropriate icon will be illuminated
NOTE:- The alarm condition must be rectified before a reset will take place. If the alarm condition
remains it will not be possible to reset the unit (The exception to this is the Low Oil Pressure alarm and
similar ‘delayed alarms’, as the oil pressure will be low with the engine at rest). Any subsequent
warnings or shutdowns that occur will be displayed steady, therefore only the first-up shutdown will
appear flashing.
NOTE:- The safety on time (used for delayed alarms) is pre set to 12 seconds and can not be
changed.
FAIL TO START, if the engine does not fire after the pre-set 3 attempts at starting, a shutdown will be initiated.
The
icon will illuminate.
LOW OIL PRESSURE, if the module detects that the engine oil pressure has fallen below the low oil pressure
switch after the Safety On timer has expired, a shutdown will occur.
The
icon will illuminate.
HIGH ENGINE TEMPERATURE, if the module detects that the engine coolant temperature has exceeded the high
engine temperature switch after the Safety On timer has expired, a shutdown will occur.
The
icon will illuminate.
OVERSPEED, if the engine speed exceeds the pre-set trip (14% above the nominal frequency) a shutdown is
initiated. Overspeed is not delayed, it is an immediate shutdown.
The
icon will illuminate.
NOTE:- During the start-up sequence the overspeed trip level is extended to 24% above the normal
frequency for the duration of the safety timer to allow an extra trip level margin. This is used to prevent
nuisance tripping on start-up.
UNDERSPEED, if the engine speed falls below the pre-set trip (20% of the nominal frequency) after the Safety On
timer has expired, a shutdown is initiated.
The
icon will illuminate.
Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant icon will be illuminated when the input is
active
