2 . The system of claim 1 , wherein the first pressure relief valve is electronically-controlled to adjust a relief pressure associated with the first pressure relief valve.
3 . The system of claim 1 , wherein the first flow control device is configured as a first restrictive orifice that creates a back pressure between the cylinder and the first restrictive orifice.
4 . The system of claim 1 , wherein the first pressure relief assembly further includes a first pressure sensor fluidly coupled between the cylinder and the first flow control device.
5 . The system of claim 1 , wherein the control circuit further comprises:
a second pressure relief assembly including a second pressure relief valve and a second flow control device, the second flow control device positioned between the cylinder and the second pressure relief valve in the control circuit.
6 . The system of claim 5 , wherein the second pressure relief valve is electronically-controlled to adjust a relief pressure associated with the second pressure relief valve.
7 . The system of claim 5 , wherein the second flow control device is configured as a second restrictive orifice that creates a back pressure between the cylinder and the second restrictive orifice.
8 . The system of claim 5 , wherein the first pressure relief assembly is fluidly coupled with a rod port of the cylinder and the second pressure relief assembly is fluidly coupled with a base port of the cylinder.
9 . The system of claim 5 , wherein a pressure setpoint of the first pressure relief valve and a pressure setpoint of the second pressure relief valve are based at least partially on data provided by a sensor system operably coupled with the control circuit.
10 . A method for an operation of a system for a boom assembly, the method comprising:
receiving, from a computing system, instructions to set a first pressure relief valve at a first defined pressure setpoint;
restricting flow of a hydraulic fluid between a cylinder and the first pressure relief valve with a first flow control device;
receiving, from the computing system, instructions to set a second pressure relief valve at a second defined pressure setpoint; and
restricting flow of the hydraulic fluid between the cylinder and the second pressure relief valve with a second flow control device.
