Systems without a negative supply Without a negative supply vacuum pump release the positive pressure from the system to atmosphere through the negative supply port The release from the negative port may be piped away to a place where this discharge causes no disturbance or hazard Alternatively a diffuser may be fitted to the negative supply port to diffuse air flow The need for a negative supply for optimum performance General Supply pressures at least 110 of range but less than the MWP there must be a difference of 10 of full scale between the supply pressure and the maximum output pressure When operating at positive or negative full scale there must be a pressure difference between supply and output to cause a gas flow Operating near atmospheric pressure or below Any controller operating near atmospheric pressure or below requires a vacuum pump or other negative supply connected to the negative supply port for optimum performance Without a vacuum supply as the output pressure approaches atmospheric pressure the differential pressure approaches zero resulting in a reduced flow to the output Reduced flow causes an increase in the time to control to atmosphere especially with large user volumes and an increased overshoot at low pressures see figures 2 3 2 4 and 2 5 Vacuum Pump Each PACE Control Module has a vacuum sensor so it is normal practice to connect a vacuum pump to the ve supply port The flow rate of the vac
