A system and method for controlling a pumps configured to pump fluid from a fluid supply to a frac iron configuration. A pressure schedule is defined, the pressure schedule including a pumps assigned to sets of pumps, wherein each set of pumps is associated with a pressure level and wherein each set of pumps except a first set of pumps is a subset of a previous set of pumps. The first set of pumps is enabled to pump fluid continuously until the fluid in the manifold has reached a predetermined pressure level. A processor then automatically disables the electric pumps that are not in the next set of electric pumps, while allowing the next set of pumps to continue to pump fluid until the fluid in the manifold has reached the next pressure level. This continues until the manifold is at the desired pressure.

Automatic pressure test and equalization to wellhead pressure

Aspects of the subject technology relate to systems and methods for injecting down-hole tools into a fracturing line. A fracturing system may include a fracturing line of a respective wellbore and a launcher operationally coupled to the fracturing line though a respective supply line at a pressure lower than a pressure of the fracturing line. The fracturing system may further include a magazine containing a plurality of down-hole tools that is operationally coupled to the launcher for sending a down-hole tool of the plurality of down-hole tools to the launcher. The fracturing system may also include a launching chamber operationally coupled to the respective supply line for receiving the down-hole tool and having a pressure automatically adjustable to substantially equal the pressure of the fracturing line after the launching chamber is sealed from the respective supply line for disposing the down-hole tool into the fracturing line.
