14 Malfunctions
Event Possible cause
10242 This is triggered when the termination
gradient is violated in a gradient-monitored
process, which leads to an abort of the
program run (in the context of clock-
controlled evacuation VT/pressure gradient
monitoring). The vacuum performance is
insufficient.
10256 Monitoring pressure gradient during
evacuation. The pressure change at
pressure sensor S1 is too low during
evacuation.

What you can do
Please check the dust filter for contamination
and replace it if necessary.
The intake area of the cooling system under
the device must be free; check for paper or
similar items underneath the device which
could stop the air flow.
Please ensure that the device is sufficiently
ventilated. Heat dissipation must be able to
take place freely, ensure ventilation;
conversion cabinets are not recommended.
Please observe the set-up conditions (e.g.
ambient temperature).
Check the loading of the device for
compliance with the permissible loading
quantities.
Check the pressure release filter in the
chamber for blockage.
