DSL voltages
DSL-internal voltage limits exceeded. Please
check the power connection and repower the
device. If the alarm still exists, call service
personnel. Electronics may be damaged and it
may be necessary to replace DSL electronics.
6
DSL Storage
A malfunction in the DSL-internal memory was
detected. Parameters are either not initialized
correctly or stored correctly. Repower the de-
vice and check parameter values. If alarm still
exists, call service personnel. Internal data
storage may be damaged and it may be nec-
essary to replace DSL electronics.
7
Flow measurement
An error in the flow measurement system de-
tected and the measurement accuracy can be
affected. Try to repower the device. If alarm
still exists, call service personnel. It may be
necessary to replace the DSL electronics or
firmware.

DSL internal
Try to repower the device. If alarm still exists,
call service personnel. It may be necessary to
replace the DSL electronics or firmware.
Only hydrocarbon
9
Oil: Density
An error in the oil density calculation was de-
tected and the measurement accuracy can be
affected. Check if device is configured proper-
ly, investigate DSL error codes to determine
precise root cause.
Only hydrocarbon
10
Oil: Viscosity
An error in the oil viscosity calculation was
detected and the measurement accuracy can
be affected. Check if device is configured
properly, investigate DSL error codes to de-
termine precise root cause.
Only hydrocarbon
11
Oil : Spec. gravity
An error in the oil gravity calculation was de-
tected and the measurement accuracy can be
affected. Check if device is configured proper-
ly, investigate DSL error codes to determine
precise root cause.
Only hydrocarbon

Path 1: No signal
Potential reasons: Process conditions, wrong
installation, defect in electronics, cabling or
sensor. It may be necessary to adjust either
installation or configuration or to replace com-
ponents. Provide DSL error codes to service
personnel for further information.
