LimitP add – Adding pressure to the maximum pressure
This value defines the addition to the maximum pressure, computed to the jacket
control.
For example, when the desired temperature is 134ºC (273ºF) the maximum
temperature maintained in the jacket will be adjusted to a temperature of 137ºC (i.e.
332kPa) - 278 ºF (48 psi)
When this pressure is not enough, it can be increased by changing the values of the
LimitP add.
If the parameter value remains Ø, the maximum pressure in the jacket will be 332kPa,
however if this value will be 10, the maximum pressure will be 342kPa.
PulsPres1 – The pressure in pulse no.1 in the pre-vacuum stage
This defines the first pulse pressure in the pre-vacuum stage. If it is defined as 100kPa,
the system will not enter steam into the chamber, however; the vacuum pump will
immediately start operating to create a vacuum.
If the value is defined over 100kPa, the system will open the steam valve to the chamber
until the desired pressure is reached.
PulsPres2 – The pressure in pulse 2 and onwards in the pre-vacuum stage
After the completion of pulse no.1, the system will enter steam by the defined value in
pulse press.
CODE 13 - PARAMETER
ReqPrs+ - The addition to the required pressure for sterilization
This parameter sets the pressure point maintained during the sterilization stage in the
following manner:
If the desired temperature is 134ºC (273°F), the required pressure (from the tables) is
305kPa (44.2 psi).
When the ReqPrs+ is Ø, the system pressure will be maintained at 305kPa (44.2
psi)during the sterilization stage. When the Reqprs+ equals 5kPa (0.5 psi), the system
will be maintained at 310kPa (44.9 psi) in the sterilization stage. It is advised to work
with a value of 7kPa (0.5 psia).
