6.2 Failure Indicators Description

Explanations :
1-
for more than the time defined as the
(P191),
Oil failure control delay
(Start Failure LED) :
2-
(High Temperature Failure LED) :
3-
(Low Oil Pressure Failure LED) :
4-
(Over Speed Failure LED)
5-
(Generator voltage Failure LED):
The Unit drives to the starter motor according to
values determined in P06 and P16. But, starting the engine is not possible in this values
the unit gives a Start Failure. In this case the LED flashes and the horn is sounded. The
unit must be reset by pressing the RESET (13) button before a fresh attempt can be
made.
Failure will be active when the High
Temperature Switch is which is connected to the Unit via Pin 8 getting excessive hot as
result of possible heating of engine. In this case the LED flashes and the Horn is sounded
and engine shuts-down without any cool-down period.
The sensor that is connected to the
Unit via Pin 7 is Normally Closed. The contact will open when Oil Pressure in the engine
reaches to proper level. If the contact will not open the engine is running and it continues
the LED flashes
and the Horn is sounded and engine shuts-down without any cool-down period.
: The unit decides to the Over Speed Failure that
depending on the values of parameters P51, P52 and P21.
The unit decides to the Generator Voltage
Failure when the Alternator Voltage is out of the values determined with P03, P04 and
P20 parameters.
the LED
flashes and the Horn is sounded and generator contactor is released if closed, engine
shuts-down without any cool-down period.
At the end of
time defined by parameter P19, if the generator speed is out of
or
and continues for of
time
period, the LED flashes and the Horn is sounded and engine shuts-down without any
cool-down period.
Generator speed is measured from alternator output frequency.
At the end of
time defined by parameter P19, if the
alternator voltage is out of
or
and continues for of
time period,
