Issue 1

By default, warning alarms are self-
resetting when the fault condition is removed. However enabling ‘all w
arnings
are latched’ will cause warning alarms to latch until reset manually. This is enabled using the 7000 series
configuration suite in conjunction with a compatible PC.
7.2.1 HIGH CURRENT WARNING ALARM
GENERATOR HIGH CURRENT
, if the module detects a generator output current in excess of the pre-set trip a
warning alarm initiates. The module shows Alarm Warning High Current. If this high current condition continues for
an excess period, then the alarm escalates to a shutdown condition. For further details of the high current alarm,
please see High Current Shutdown Alarm.
High Current Warning Alarm is self-resetting when the overcurrent condition is removed.
7.2.2 SHUTDOWNS
Shutdowns are latching alarms and stop the Generator. Clear the alarm and remove the fault then press Stop/Reset
to reset the module.
Example
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 ‘active from safety on’ alarms, as the oil pressure will be low with the
engine at rest).
Display
Reason
FAIL TO START
The engine has not fired after the pre-set number of start attempts
EMERGENCY STOP
The emergency stop button has been depressed. This a failsafe
(normally closed to battery positive) input and will immediately stop the
set should the signal be removed.
Removal of the battery positive supply from the emergency stop input will
also remove DC supply from the Fuel and Start outputs of the controller.
NOTE:- The Emergency Stop Positive signal must be
present otherwise the unit will shutdown.
FUEL USAGE
Indicates the amount of fuel measured by the fuel level sensor is in
excess of the
Fuel Usage
alarm settings. This often indicates a fuel leak
or potential fuel theft.
PHASE ROTATION
The phase rotation is measured as being different to the configured
direction.
OVERSPEED
The engine speed has exceeded the pre-set trip
UNDERSPEED
The engine speed has fallen below the pre-set trip after the
Safety On
timer has expired.
GENERATOR OVER
FREQUENCY
The generator output frequency has risen above the preset level
GENERATOR UNDER
FREQUENCY
The generator output frequency has fallen below the preset level
GENERATOR OVER VOLTAGE
The generator output voltage has risen above the preset level
GENERATOR UNDER
VOLTAGE
The generator output voltage has fallen below the preset level
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 text of the fault.
