5.1 Simulation
The figures in brackets relate to the figures under "4.1 Indicating and adjustment elements“.
• Set the rotating switch (7) to position F "Simulation“. The actual measured value is taken over and flashes. The
simulation is immediately active. Level changes are not indicated during simulation.
• With the keys (3 and 4) you can modify the value of the indication. You can adjust any requested value within
the scaled range and hence test also the function of the current output and the mounted output relays.
• After the simulation is finished, you have to set the rotating switch (7) again to position 0 “OPERATE“. Hence
the simulation is interrupted and the actual measured value is indicated again.
5.2 Fault signals
The following fault signals can be indicated on the display:
Fault signal/Failure Removal/Measure
E003 Failure during selfcheck Relays deenergize (safe condition), current output 22 mA.
Carry out a reset (see 4.4 Reset). Hence all adjusted values are reset to
factory setting.
When the failure occurs again, send the instrument to our repair
department.
E014 Shortcircuit Relays deenergize (safe condition), current output: 22 mA.
Sensor current > 21 mA.
Check the terminals and the connection line to the sensor.
E015 Line break Relays deenergize (safe condition), current output: 22 mA.
Sensor current < 3,6 mA.
Check the terminals and the connection line to the sensor.
Probably no sensor connected.
E017 Relay switch points The LED of the concerned relay flash.
Difference too small The concerned relay deenergizes (safe condition).
Repeat the adjustment "4.2 Adjustment“.
Increase the difference between the two relay switch points.
E021 Indication scaling Repeat the adjustment "4.2 Adjustment“.
Difference too small Increase the difference between the two indication values.
E116 Pumps in different The LED of the concerned relay flashes.
mode The concerned relay deenergizes (safe condition).
Change to menu stage 1.
Check the switching function of relay 1.
Set all relays which are used for pump changeover function to the same
switching function like relay 1 or deactivate the pump changeover
function for these relays.
