Message resets itself
after setting all outputs to
"automatic mode". To set
several outputs, use "user
level" - "manual mode".
Arrange a maintenance acc.
to instruction manual and
after this reset the message.
Exceeding temperature at
T1 again and again signifies
too high temperatures at
the point of implementation.
On site tasks could be
necessary (cooling vessels
etc.) to avoid damages
of the device (defective
components, membrane,...)
