Error messages
Any malfunctions during operation will be identified by an error message on the display.
Once a serious error message has been displayed, the lift moves to the top end position and the device can no longer be operated.
Proceed as follows in such cases:
- switch off device using the mains switch,
- carry out corrective measures,
- restart device.
Error message Effect Cause Correction
No pressure change Pressure gradient analysis does
not show any deviation Pump is not running
Vacuum hose isn't connected
RV 10.4002 valve control cable
is disconnected
Failure in hose system
Recipient isn't closed
Check pump control cable connection
Check pump power supply
Switch on pump
Check vacuum hose connection (pump,
recipient)
Check RV 10.4002 valve control cable
connection
Check correct vacuum hose connection
(IN / OUT/ VENT)
Close recipient
System not tight Pressure gradient analysis
shows pressure deviation, but
set value cannot be reached.
Pressure set value cannot be
reached. Vacuum hose connection isn't
tight
Recipient isn't tight
Vacuum pump power isn't suf-
ficient
Venting valve leakage Check vacuum hose connection
Check recipient
Check technical data of the pump
Contact service department
Pressure out of range Vacuum is out of range
Vacuum is bigger than room
pressure
Pressure in the recipient is too
high
Sensor is broken. Check the air flow of pump and vent re-
cipient
Contact service department
Vacuum sensor error Vacuum sensor output is too
low Sensor is not connected
Sensor is broken. Check the sensor connection
Contact service department
Vacuum calibration
error Vacuum calibration value is out
of range Input wrong vacuum actual va-
lue when doing calibration.
Set wrong vacuum calibration
value
Sensor is broken Check and calibration again
Check the set calibration value

Boiling point detec-
ting error Boiling point cannot be detec-
ted.
Differ-temperature analysis
does not show boiling point Heating bath does not heat up
Solvent with extreme low boi-
ling point is used
Check heating bath
Solvent distillation only manually
Venting error Pressure gradient analysis does
not show any deviation after
pressing the "Venting" button. Recipient wasn't evacuated
Failure in hose system
Venting valve doesn’t work
Front foil button is damaged
Evacuated recipient
Check correct vacuum hose connection
(IN / OUT/ VENT)

Analog pump not
connected Analog pump is disconnected Check the analog pump cable connection
No rotation Rotary drive does’t start or ex-
hibits very large speed variation Rotary drive is overload or blo-
cked
Motor or motor cable is dama-
ged Reduce the load

Temperature sensor
not connected Differential temperature shows
big minus value Temperature sensor is not con-
nected
Temperature sensor is damaged Check the Temperature sensor connec-
tion
Contact service department
No temperature diffe-
rence No differential temperature in-
crease of cooling water No solvent or too less solvent is
distilled
No water flow
Water flow is wrongly connec-
ted Check the solvent
Check flow of cooling water
Check flow direction of cooling water
Temperature out of
range Differential temperature out of
the measurement range Too fast distilling
Temperature sensor is damaged Increase the set vacuum
