Display (English) Display (German) Description Possible cause of error and
remedy
malfunction S1 Bruch/Schluß S1
Interruption/short circuit in the
connection of sensor coil 1 Check the lines between sensor
coil and transmitter. Measure
coil resistance.
malfunction S2 Bruch/Schluß S2
Interruption/short circuit in the
connection of sensor coil 2 Check the lines between sensor
coil and transmitter. Measure
coil resistance.
exc. too large Erreger zu groß
A excitation current exceeding the
limit will be detected. Asymmetric filling of the flow
tubes, air bubbles when measur-
ing liquids or:
condensate in the flow tube
when measuring vapor or gases
Electrical cause:
Check the lines between excita-
tion coil and transmitter. Check
for bonding. Check the excitation
coil and the magnet.
exc. too small Erreger zu klein
A excitation current exceeding the
limit will be detected in the case
of transmitters approved for cus-
tody transfer operations. Check the lines between excita-
tion coil and transmitter.
meas. circ. sat. Messkreis überst.
The instrument transformer for
phase metering is overloaded.
The measured phase displace-
ment is too large. Mass flow rate is too high.
QM > 110 % QM > 110 %
The mass flow rate exceeds the
set upper-range value for the flow
rate by more that 10 %. Reduce the flow rate and adjust
the measuring range if neces-
sary.
curr. 1 saturated Strom1 Überst.
The output of current interface 1
is overloaded. Based on the se-
lected settings and the currently
assigned measured variable, the
current to be output is > 21.6 mA. Check the upper-range value
and the flow rate settings.
curr. 2 saturated Strom2 Überst.
The output of current interface 2
is overloaded. Based on the se-
lected settings and the currently
assigned measured variable, the
current to be output is > 21.6 mA. Check the upper-range value
and the flow rate settings.
pulse out satur. IMP übersteuert!
The pulse output is overloaded.
The current measured value re-
quires a pulse rate, which can no
longer be generated with the help
of the set pulse duration and
pulse value. Check pulse duration, pulse
value, and measuring range.
Check the flow rate.
Temperature > Temperatur>MAX
The measured temperature ex-
ceeds the set upper-range value Product temperature is too high;
adjust the temperature range
