Service
☞
Turn the rotary/push knob to the right/left to select a menu option.
☞
Press the rotary/push knob.
☞
Turn the rotary/push knob to change the value (the magnitude of the
change is dependent on the speed at which the knob is turned).
☞
Press the rotary/push knob again to complete the process.
ESC key: Exit menu, all changes to switch settings are reset, the cali-
bration remains unaffected.
Switching valves and pump
The Service menu is used to check functionality during servicing by di-
rectly switching the valves and pump e.g. RV10.5001.
The RV10.5001 valve switches the water circuit on and off. This row
also shows the current cooling water flow rate.
Calibrate
The “Calibrate” option is used for calibration of the temperature sen-
sor.
The temperature difference displayed will be calibrated to zero. This ac-
tion cannot be reversed.
The temperature sensor must be calibrated whenever it is replaced or
changed, or if a new temperature sensor is installed.
Please contact the Service department.
The temperature sensor supplied with the system is calibrated ex-
works.
Performing calibration
☞
Activate the “Calibrate” menu option by turning the rotary/push
knob.
☞
Remove both sensors. To remove a sensor, push back the outer ring
to release the locking device on the push-in connector, while at the
same time pulling the temperature sensor out of the connector, see
Fig. 26.
☞
To reconnect a temperature sensor, push it into the push-in connec-
tor until the limit stop is reached; an initial resistance will be felt.
☞
Fill water at room ambient temperature into a glass beaker (approx.
500 ml). Fully submerge both sensors into the water, see fig. 27.
☞
Wait until the temperature display in the “Service” menu, menu op-
tion “Calibrate” has stabilised, e.g. 0.2K.
☞
Press the rotary/push knob.
The temperature difference displayed will be calibrated to zero.
Calibration is only possible within the temperature range +0.5 K to
-0.5 K. If the temperature is outside this range, then either a tem-
perature sensor is faulty or connected incorrectly. Please contact
the Service department.
If the characteristics of the cooling water supply deviate significantly
from the specifications given in the “Technical specifications”, with
the result that the initial conditions for automatic distillation are not
achieved, then it may be necessary to recalibrate the temperature
sensors. This may, however, lead to a reduction in the accuracy with
which the distillate quantity is measured in “Auto-distillation” mode.
Operation hours
This value serves as informaton and cannot be changed.
