SITRANS FX300

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	Signal converter continues to display the
	flow rate qmin	current flow rate but the accuracy of the
		measurement may be affected.
Q too high	Flow rate higher than the set maximum	Corrective measures depend on the
	flow rate qmax	application!
		If the flow rate exceeds the maximum
		value, the measuring sensor may be
		physically damaged.
Inv. Config.	Invalid configuration data in FRAM	Check entire configuration!
	(permanent memory)	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 qmin
		2. Excessive pipe vibration and faulty
		flow profile
Low Signal	Amplitude of vortex signal is too low	1. qmin ok?
		2. If qmin OK, contact service
Hi. Signal	Amplitude of vortex signal is too high	Occurs with media of high density
		1. Check qmax
		2.If qmax OK, contact service
L.Temp.Phy	Operating temperature lower than	Take corrective measures within
	specified	process.
H.Temp.Phy	Operating temperature higher than	Take corrective measures within
	specified	process as quickly as possible,
		otherwise both the measuring sensor
Hi.P.Phys	Pressure higher than specified
		and the signal converter may be
		damaged.
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.
