As a rule, warnings are emitted if certain operating conditions are not (yet) reached or if an
action is not possible.
Acknowledge the warning with the key and the unit will return to normal status.
Warning 2
Compensation pressure cannot be maintained.
Possible cause:
Capillary or capillary holder not attached or only connected
loosely.
Solution:
Check all connections and tighten.
Activate Function 0 to change the capillary and when the
capillary holder is open.
Warning 3
Micromanipulator does not react.
A micromanipulator is connected but does not react to a
start pulse from the FemtoJet
®
express.
Possible cause:
Micromanipulator is switched off.
INJECT function on manipulator is not released.
No limit is set on the micromanipulator.
In the INJECT function on the micromanipulator,
synchronization is set to limit (SYNC = LIMIT).
Solution:
Switch on the micromanipulator and make it operational.
Disconnect the cable to micromanipulator.
With SYNC = LIMIT, trigger semi-automatic injection via the
micromanipulator only.
Warning 4
The attached external pressure has changed greatly. When
switched on, the automatic valve adjustment took place for
a different pressure (displayed value to upper right).
Solution:
Switch device off and on again. The automatic valve adjust-
ment will be carried out with the present pressure.
Note:
This warning is issued only once. Pressing the
key will remove the error message. It will
generally be possible to continue work. However, optimal
valve regulation should not be anticipated.
