3. Now the monitor will display “MISSED” alternating with “FAN 1”, indicating that the first
fan sensor may now be connected. Connect the fan sensor.
4. The process is the same for rest of the sensors in the sequence. When the monitor
requests a sensor that will not be used in the configuration, press the OK key. The
sensor will be assigned a disabled status, and the monitor will prompt for the next one in
the sequence. A sensor disabled by this method can only be enabled by repeating the
entire Sensor Learn procedure. To skip the rest of the sensors of the current type, the OK
and MODE keys can be pressed simultaneously. For instance, if you are being prompted
for Shaft sensor number 2 and no more shaft sensors are to be installed the pressing of OK
and MODE simultaneously will skip the rest of the shaft sensors.
5. If the message TYPERR appears on the top line of the display, it indicates that the
sensor just connected is not of the correct type for the function being learned, e.g. a bin
level sensor is connected when the monitor prompts for a shaft sensor.
6. When all sensors in the list have either been learned or skipped, the installation is
complete. The monitor automatically advances to its normal operating mode, in which
the ground speed is displayed. Since the shafts are not rotating, alarms will be soon
generated. These will need to be silenced with the OK key.
7. To verify the installation, power down the monitor, then up again (with no buttons held).
Now, the names of the learned (but not the skipped) sensors will quickly flash by on the
display as the unit goes through its normal “wake up” sequence, after which it advances
to its default operating mode, in which the ground speed function is active.
Radar Speed Sensor
The RADAR ground speed sensor may be plugged into the monitor either before or after the
above LEARN procedure. The monitor will recognise the RADAR speed sensor as soon as it
is plugged in.
Installation Precautions
Special care must be taken when the same type of sensor is used for different functions. For
example, if the installer plugs in a shaft sensor and the ground speed sensor in opposite order,
since these can be the same type of sensor, the monitor would accept this, not knowing where
the sensors actually are. The monitor would interpret shaft RPM data as the ground speed
shaft data and vice versa, resulting in faulty operation.
Most configured sensors can be prevented from generating alarms even though they were
configured at LEARN time. This is done by changing the appropriate sensor setting (for
example, zeroing shaft pulses per revolution). This is further explained in the section on Set Up
/Changing Settings.
