Combinable parameters/Refractory period

For safe operation the system is allowing the following combinations of program parameters.
Refractory periods are rest times in which a consecutive run cannot be started. They prevent the system
from overheating. However, the risk of overheating only exists during extensive high throughput appli-
®
cations using Precellys
which will shut off the motor if the temperature rises above the limit. Therefore, from firmware version
4.1 (12/2011) on refractory periods do not exist any more in Precellys
by pressing 'cancel' in Precellys
The actual firmware version of the system is displayed when pressing 'cancel' for 10 sec after switching
on the unit.
