Sets the maximum and minimum pressure limits for the pump.
Max is the maximum pressure limit at which the pump will switch itself off, protecting the analytical system against over-pressure.

400 bar (5800 psi) |
| G1312B Binary Pump SL | 600 bar (8700 psi) |
G4302A Binary SFC Pump | 600 bar (8700 psi) |
G4782A Binary SFC Pump | 600 bar (8700 psi) |
| G4220A Binary Pump | 1200 bar (17400 psi) for flow rates up to 2 mL/min. For flow rates between 2 mL/min and 5 mL/min, the maximum pressure ramps down to 630 bar (9135 psi). |
| G4220B Binary Pump VL | 1200 bar (17400 psi) for flow rates up to 1 mL/min. For flow rates between 1 mL/min and 2 mL/min, the maximum pressure ramps down to 1050 bar (15228 psi). |
G7112B Binary Pump | 600 bar (8700 psi) |
G7120A High Speed Pump and G7132A Bio Binary Pump | 1300 bar (18850 psi) for flow rates up to 2 mL/min. For flow rates between 2 mL/min and 5 mL/min, the maximum pressure ramps down to 800 bar (11600 psi). |
Min is the minimum limit at which the pump will switch itself off, for example, if any solvent reservoir is empty. This prevents system damage caused by pumping air.
Limits: You can set the minimum pressure limit to any value between 0 and the upper pressure limit setting.

The minimum pressure limit is activated only if the pressure starts above the specified value and falls below it. It is not activated if the pressure starts below the specified value. For the system to create an error, the limits must be exceeded for a few seconds. |
