Pressure Limits Screen
From the Start screen press Edit > Config > Safety to reach the Pressure Limits screen that
shows the high and low pressure limits and the associated safety files.
1. Use the Up or Down arrows to navigate to the High or Low lines, then key in the desired
values. The range is 0–21 MPa for the high and low limits.
2. Press ENTER to confirm your choice.
NOTICE
Pressure limits are model and configuration dependent and subject to automated validation.
Ensure that the pressure limits entered are suitable for the safe and correct operation of your
system.
NOTE
If File 21 is being executed, the pressure limit is automatically raised by 10%; then if the new
pressure limit is passed, the pump stops.
When the low pressure limit is crossed by decreasing values, the eect is delayed by 0.3minute.
The delay is to allow the Method Program to continue if an air bubble creates a brief and abrupt
pressure decrease.
3. Press Next to advance to the Other Safety Functions screen.
