2.6 MOTOR AND ALARM PARAMETER READING
2.6.1 POSITIVE MOTOR PROTECTION INPUTS
Some modern motors are equipped with positive outputs to indicate the Low Oil Pressure and High Motor Temperature anomalies. The
M02 is pre-arranged to communicate with these motors by modifying the JUMPERS on the MP02 unit.
2.6.2 ANALOGUE MOTOR PARAMETER READING INPUTS (PRESSURE, TEMPERATURE AND FUEL
LEVEL)
The three inputs 15-16-17 used to read the pressure, temperature and fuel level can be configured using the SW2 switch (on the MP02
unit) for motors type MTU that output 0-10V for the above-mentioned readings.
When SW2 is configured to “ON”, normal motor probes (transducers) of a VDO or VEGLIA type can be used (which can be configured
from the Misc. Settings Menu). Since they are not linear, the working fields available are restricted by the limits of the transducers.
Where the probe is not installed, no indication will appear on the display automatically.
When individually configured as “OFF” the three inputs operate at between 0 and 10V, and are connected directly to the MTU motors
and others of the same concept for taking motor measurements. The reading scale can be changed from the Measurements Menu.
