A method of restricting access to a control panel of a metering pump, the method comprising:
- receiving a user input signal from a user interface;
- determining the user input signal is a lockout access code;
- and
- switching the metering pump between a locked configuration and an unlocked configuration based on a receipt of the lockout access code, wherein in the locked configuration, the control unit selectively permits the pump to provide a prime function while keeping an operational parameter of the metering pump maintained in response to the user input signal, and wherein in the unlocked configuration, the operational parameter is adjusted in response to the user input signal.
