Pressure Limits (Integrated LC Isocratic Pump)

Sets the maximum and minimum pressure limits for the pump.

Max

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

Flow Rate	Pressure Limit
flow rate <=5 ml/min	600 bar (1220) 400 bar (1120 and 1220 VL)
flow rate >5 ml/min	200 bar

Min

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 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.
