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.
