Multiquip EM517648B Control Panel for LS Series Concrete Pumps - OEM Replacement Part

The control panel assembly serves as the central command interface for LS series concrete pumps, managing critical functions including stroke control, jog operations (A/B cylinders), automatic/manual mode selection, remote control operation, volume adjustment, flow direction (forward/reverse), and digital display programming. This is the universal digital control box (MQ Part #517648A referenced in technical documentation) that coordinates hydraulic cylinder operation, proximity switch monitoring, and slave circuit management during concrete discharge cycles.

Factory pre-programmed for LS300 configuration, this control panel can be reprogrammed on-site to match specific pump model configurations including variations with Parker Pac 65 or P175 hydraulic pumps, Perkins, Zenith, or Kubota engines. The display carrier board interfaces with multiple control inputs: stroke/jog A and B cylinders, remote/local switching, automatic/jog mode selection, forward/reverse flow control, volume adjustment (+/-), and system reset functions. Purple wire (common) connects to +12 VDC power bus as specified in electrical diagrams.

• LS300G
