Error messages
“Tank full”
state *, display freezes
at maximum or minimum value
Not a fault. The level has reached (and may have
exceeded) the entered max. limit value.
It then prints the maximum (for level) or
the minimum (for distance).
There is none. The measurement will be normal within the programmed limits.
“Tank empty”
state * display
freezes at maximum or minimum
value
Not a fault. The level has dropped to the lower dead zone
so there is no further signal detected.
It then displays the maximum (for distance) or minimum (for
level).
There is none. The measurement will be normal within the programmed limits.
“Tank full”
and
“Level lost”
state *,
display freezes at maximum or
minimum value
Not a fault.
The level has risen to the upper dead zone so there is no
further signal detected.
Empty the tank below the upper level and check functioning!
“Level lost”
state *, display freezes The device has lost the signal it is looking for, but has not
yet found the reflected signal.
This can occur if the signal has dropped below the
threshold and parasitic signals from the flange or tank
failure do not allow the true signal to be found.
Ensure that the level in the tank drops below the maximum and check the
measurement.
If no signal is detected, change the threshold value manually as described in
"
Threshold line
." Use the oscilloscope chart and threshold setting functions (0).
“Reference not found”
state *
Occurs when there is a problem with the time base of the
measurement card circuit.
Contact HYCONTROL!
“Level lost”
and
“Reference not
found”
state *, display freezes
The probe has been subjected to electrostatic discharge
(ESD).
The device starts searching for the measuring signal again and displays the result.
If the display remains frozen, the device may be damaged due to an ESD
discharge and will need to be replaced. Contact HYCONTROL!
“Flange not found”
state *
The instrument is incorrectly programmed for a cable or rod
probe while a coaxial probe is installed.
But it is possible that a long tank stub will cause a large
amount of flange attenuation.
Contact HYCONTROL to address the fault.
Event
Fault
Solution
“Delay out of limits”
state *, display
freezes
The transmitted measurement signal
cannot be detected.
The device will not operate as long as this
error persists.
The device may need to be replaced. Contact HYCONTROL!
“Negative voltage error”
*
Occurs when there is a problem with the
time base of the measurement card circuit.
Contact HYCONTROL!
“VC01 voltage error” *
“VC02 voltage error” *
“Reprogramming FPGA” *
* The device is connected to the HyView
software and listed in the “Device Status” window (or the “Markers” window) with active polling
.
