ALARM TYPE
Status
This type of alarm will display a message on the
screen. The message will not be logged. This is the
lowest priority of alarm types.
Warning – Non-Latched
This type of warning will activate the audible alarm,
and flash the alarm LED and display back light. The
associated message will be displayed on the screen.
When the user accepts the warning (by pressing the
Enter key), the back light will stop flashing, and the
alarm LED will be on continuously. The message will be
displayed on the alarm screen, but the user will be able
to scroll through other screens. The LED and message
will clear when the warning condition clears. This type
of warning is logged.
Alarm – Latched
This type of alarm will act similarly to the non-latched
warning, except that the alarm does not clear when the
alarm condition clears. When the alarm condition
occurs, the audible alarm sounds, the LED and back
light flash as before, and the user must accept the
alarm to stop them. The alarm will continue to be dis-
played on the screen even after the alarm condition has
cleared. The user must either press the Reset key or
turn the key-switch to the OFF position to clear the
alarm after the alarm condition has cleared. This type
of alarm is logged.
Shutdown
This type of alarm will act similar to the latched
alarm, but it also will stop the engine when the alarm
condition occurs. It can be reset only by turning the
key-switch to the OFF position. All shutdown alarms
are latching, and this type of alarm is logged.
Alarm Status
This is the value at which the alarm is active. For ana-
log alarms, it is a number corresponding to the alarm
limit. Digital alarms are either “normally open” or
“normally closed,” and an alarm is generated when
the input is not in the normal state.
Alarm Message
Each alarm will have a message associated with it. The
analog alarm messages will be preset, and the digital
alarm messages and user-defined analog messages will
be entered via the keypad or the serial link.
OTHER ALARMS
Overcrank
This alarm is unlike other alarms as it is not associ-
ated with an analog or digital signal. The user is able
to define the number of crank attempts, the length of
each crank attempt and the rest time between
cranks. After the last attempt has been made, an
overcrank alarm will be generated. The user must
turn the key-switch to the OFF position to clear the
alarm.
Coolant Level
This alarm is generated by the coolant level detector.
This device senses whether coolant is present or not.
It has no user-definable level setting and is a shut-
down alarm that is active after the hold off time.
There are no user-definable parameters for this
alarm.
PROGRAMMABLE PARAMETERS
The E option panel allows the user to configure vari-
ous options to control the generator starting and
stopping cycles, and the way that the alarms operate.
Parameters are entered either from the control mod-
ule or via the serial link. A description of the pro-
grammable parameters follows:
PREHEAT ENABLED
This parameter determines how the preheat function
works. The preheat can be fully disabled, enabled
before starting only (for the duration of the preheat
time), or before and during starting (for the duration
of the preheat time and also while the starter is
engaged). Note that if the user wishes to engage the
preheat during starting but not to have a preheat
before starting, it is possible to set the preheat time
to zero.
PREHEAT TIME
When a start command is received, some engines
require preheating before the generator attempts to
start. When the preheat function is enabled, this
parameter allows the user to determine the time that
the preheat contact closes before activating the
starter solenoid.
START TIME
Once a start command has been received and
the preheat time has expired (if enabled), the starter
solenoid will be engaged. This parameter allows the
user to determine how long the starter solenoid is
engaged before the start attempt is regarded as hav-
ing failed. If the generator does not start within this
time, the generator will wait for a preset time before
attempting to start again. The user also can program
the number of start attempts the generator tries.
