6.4 Error messages
Error message Cause Measure
No Signal No signal from vortex amplifier Check connector
In the event of measuring sensor
problems contact service.
Low freq Sample frequency too low Contact service.
High Freq Sample frequency too high Contact service.
Low Flow Flow rate less than the set minimum
flow rate q
min
Signal converter continues to display the
current flow rate but the accuracy of the
measurement may be affected.
Q too high Flow rate higher than the set maximum
flow rate q
max
Corrective measures depend on the
application!
If the flow rate exceeds the maximum
value, the measuring sensor may be
physically damaged.
Inv. Config. Invalid configuration data in FRAM
(permanent memory)
Check entire configuration!
Contact service if error message
persists.
Amp. Fail Error in the pre-amplifier stage Contact service.
Chk. Instal. Quality of the vortex signal too poor 1. Check q
min
2. Excessive pipe vibration and faulty
flow profile
Low Signal Amplitude of vortex signal is too low 1. q
min
ok?
2. If q
min
OK, contact service
Hi. Signal Amplitude of vortex signal is too high Occurs with media of high density
1. Check q
max
2.If q
max
OK, contact service
L.Temp.Phy Operating temperature lower than
specified
Take corrective measures within
process.
H.Temp.Phy Operating temperature higher than
specified
Take corrective measures within
process as quickly as possible,
otherwise both the measuring sensor
and the signal converter may be
damaged.
Hi.P.Phys Pressure higher than specified
Tsens Shrt. Temperature sensor short circuit Shows error at temperature sensor!
Contact service.
Tsens Open Open temperature sensor
P. Sen. Fail Faulty pressure sensor Displays error at pressure sensor!
Contact service.
