IMMEDIATE = Alarms/Warnings with this qualifica-
tion only become active immediately after the engine
has started.
Sensor Failure Check
When this field is set, the input sensor is checked
for short circuit or open circuit failure. Normally
each of the inputs are conditioned externally to be 4-
20mA current loops. Any currents outside this range
indicate a sensor failure. This will cause an alarm to
occur. The alarm can be selected to shut down the
engine if so desired via the next field. The alarm will
be entered in the alarm log.
Shutdown on Sensor Failure
When this field is set, the engine will shut down if
there is a sensor failure. If the field is unchecked, the
failure will just cause an alarm message to appear
and the audible alarm to sound. The alarm will be
entered in the alarm log.
OTHER ANALOG OPTIONS
Event Log
When set, the channel measurement is compared to
the setpoint with either the GT or LT options. Once
the condition is met (eg measurement GT setpoint)
the event is logged along with a date/time stamp into
the volatile memory based event log. Six other param-
eters that can be chosen by the customer will also be
logged. Volatile means that when power is removed
from the unit, the memory will be lost.
Analog Outputs
There are no analog outputs available for customiza-
tion.
ANALOG SENSOR RATINGS
Typically the sensors used by the manufacturer have
the following ratings:
Temperature
Pressure
35 - 300 deg. F
0 - 150 psi

OUTPUT FUNCTIONS
Output functions are flags that are set/reset by the
internal program to indicate a certain status, for
example "Engine Running". The Measurement Engine
allows these flags to be treated as "channels" that can
be made into alarms/warnings, display messages,
operate real outputs and also be fed as inputs to the
ILC. For example, use the "Ready To Start" output
function to operate a relay by mapping it to a physical
output via GenLink, or you could feed it into the ILC
to do combinatorial logic.
