Sensor Fault Setup
Sensor fault alarms can be used to detect sensor
readings which are out of valid ranges such that they
indicate the sensor or its connection are faulty.
Thresholds are typically evaluated against the raw
analog readings. To configure the sensor fault ranges for
an analog input:
Select the channel ID of the sensor for which you
1.
want to define sensor fault ranges.
See 3-48. In the Sensor Fault area, select
2. Figure
the type of sensor fault (A). Sensor faults can be a
warning, alarm, shutdown or disabled.
Select when the sensor fault will be active (B),
3.
choices are No Mode, Always, Immediate, and
Hold Off.
Set the GT Setpoint (C), this is the value above
4.
which any reading is considered faulty.
Set the LT Setpont (D), this is the value below
5.
which any reading is considered fault.
Enter the number of seconds to delay (E) after the
6.
threshold is reached before triggering the fault.
Select "Apply Changes" (F) to save the settings.

Event History Setup
See 3-49. The Event History Setup screen allows
Figure
you to record a timestamped event in the event log. An
event can be a digital or analog event, for example when
oil pressure exceeds 200 psi. The example below shows
the setup for a digital event.

Limiting at 300% Rated Current
The 300% Rated Current Limiting feature limits the
maximum output current on all legs of the alternator to
less than 300% of the rated current of the generator.
When this feature is enabled, the current is controlled so
downstream breakers have a better chance of isolating
the fault. When this feature is not enabled, the Main
Circuit Breaker (MCB) might trip before the downstream
breakers can isolate the fault.
