Reason for error/rectification
(spare parts  ä 109)
Cause:
Simulation is active.
Remedy:
Switch off simulation:
• FF: Transducer Block "Transducer_CH1"
(base index: 1400) or Transducer Block
"Transducer_CH2" (base index: 1500) 
Parameter "Simulation - Measurand"  OFF
• Local display: SUPERVISION  SYSTEM 
OPERATION  SIM. MEASURAND ( OFF)
Cause:
The medium velocity has exceeded a value of
0.1 m/s.
Remedy:
Check whether all prerequisites for carrying out a
zero point adjustment have been met.
Cause:
Communication error. No communication with
measuring amplifier.
Remedy:
1. Switch power supply off and on again.
2. Check whether the electronics boards are
correctly inserted in their holders
