Description
The device simulates a measurement
value that is set in menu item B1.1
Set Value. This measurement value
can be a level, distance or reflection
value. If you made a strapping table,
the device can also simulate a volume
or mass value.
The device simulates a current output
value that is set in menu item B1.2
Output. The current output test range
is 3.6. 21.5 mA.
The device simulates a measurement
value. You can use the HART®
interface of the device to simulate a
measurement value.
The device simulates a current output
value set in sub-menu B1 Simulation
(distance, level, ullage volume, ullage
mass, linearized distance, volume,
mass or linearized level).
The system monitor sets the device
to a simulated current output value.
The voltage supplied to the sensor is
too low.
The signal amplitude is too large. It is
possible that the signal is saturated.
No signal peak was found in the
Search Window for a long time (>20 s).
The signal peak is in the blocking
distance (refer to menu item C1.5
Blocking Distance). There is a risk that
the tank is too full.
The temperature of the sensor is not
in the specified limits.
The temperature of the converter is
not in the specified limits.

OPERATION
Corrective action
Push "Enter" to stop the test.
Push "Enter" to stop the test.
Use the HART® interface to stop the
test.
Push "Enter" to stop the test.
Restart the device.
Do a check of the power supply.
Make sure that the device installation
agrees with the data in the handbook.
If the message is shown again, tell the
supplier.
Make sure that the device installation
agrees with the data in the
handbook. The antenna must be in
the correct position and not installed
above objects in the tank. If it is
necessary, change the device settings
and do a new empty spectrum
recording.
If the message is shown again, tell the
supplier.
Make sure that the device settings are
correct and the process conditions are
in the specified limits.
Make sure that the device is operated
in the permitted ambient temperature
range.
Make sure that the device is operated
in the permitted ambient temperature
range.
