What is the recom-
mended way to open
the lid during a process
run?
Select the lid release key and wait until the status mes-
sage (at the top pg the right hand box, on the monitor-
ing screen) says ‘Lid released’ before opening the lid.
Note: As you have requested an action, you must allow
the instrument time to complete it’s original activity,
and then implement the action. If you don’t do this,
your subsequent actions might cause you unnecessary
problems. On no account simply open the lid, as this
causes and alarm.
Why is the minimum
time in the first wax
bath 30 mins?
The minimum immersion times for the wax baths are:
First wax bath - 30 minutes
Additional wax steps - 5 minutes each
You need to hold the wax in the chamber for sufficient
time to heat the surface of the level sensors. If the wax
is not hot around the sensor/s then when the wax drains
out, a covering of wax will remain over the sensor. The
instrument still registers wax up to that level and will
therefore keep trying to ‘drain’ that wax out. 30 minutes
is the time it takes to ensure that the level of sensors are
all up to temperature.
How can a step be
deleted in a programme?
Use the Delete Step key. If you select ‘0’ time in a
position, Excelsior ES will still draw the fluid into the
reaction chamber and then drain it immediately after
entering the chamber.

ity rotation setting?
