4.9 Pre-heating function
The pre-heating function has an influence on how the step time is counted while a program is
running. When this feature is activated, the controller only starts counting the step time when the
nominal chamber temperature is reached
for the first time
.(„Act. temp“ is higher than nominal
value „Temp min“).
There are two possible settings:
1) The program that is running is not interrupted and the step time counter starts automatically.
2) The program is paused and the displa
y will show the message „Temperature reached!“, the
„Start/Stop“ button will be flashing. The program will only be resumed when the „Start/Stop“
button is pressed , at which point the step time counter will start.
Be aware
As soon as the nominal temperature has been reached, the message
"Temperature
reached! Continue?"
will be shown, even if the rest time interval is still running.
Hint
This function is pre-configured by your service technician!

Standby
As soon as the controller is connected to a power source it will automatically boot up. This can take up
to 1 minute.
Be aware
Please do not use pointy objects to operate the controller (e.g. pointed fingernails, biros,
sharpened pencils or screw drivers). Only use blunt, soft objects, as e.g. your finger tips, a
rubber or similar objects.
On the standby mask the current values and nominal values are shown as well as the current program
and step numbers.
Hint
During a data transfer between the PC and the controller the standby mask is hidden and an
status page is shown.
