Introduction
This document is designed to familiarize a user with the MPC-20-R2 and explain how to navigate the interface
and modify the settings when installing/operating the controller. The Quick Set Up guide assists with
establishing the different functions in the MPC-20-R2 for system setup. Before attempting to set up the
controller, be sure to read and understand this manual in its entirety.
Murphy PowerCore 20 Revision 2 (MPC-20-R2)
The Murphy PowerCore 20 Controller (MPC-20) is a general all-purpose manual/auto start and manual/auto
throttling engine controller. The controller is purposed primarily for pump and irrigation applications; however,
it is versatile and flexible enough to be used on many applications outside pump and irrigation. This is a
powerful controller that supports J1939 CAN protocols for electronically governed engines as well as
mechanical engines for fault and safety shutdowns.
The MPC-20-R2 is flexible in many aspects. The flexibility consists of the ability to:
•
use in most applications where auto start or auto throttling is required or desired;
•
use the same controller on electronically governed J1939 and mechanical engines;
•
establish multi-level securities in the menu structure when using the configuration tool;
•
use the same controller on 12VDC or 24VDC systems;
•
use as auto start and/or manual start controller;
•
use as manual throttle and/or auto throttle controller;
•
change the input type for the analog inputs;
•
use additional analog inputs as digital ground inputs;
•
assign functions and actions to digital inputs;
•
use digital inputs as battery or ground inputs;
•
be mounted in all-weather environment;
•
be customer-mounted in panel of choice.
Engine Application States and Delays
While reprogrammable, the MPC-20 follows a standard operating sequence. This operating sequence is a
set of machine states that happen in a predetermined order. Machine states and/or delays can be set to zero
if not needed or adjusted to fit the application. The following states and delays will be executed during the
auto sequence, provided that the corresponding timer has not been set to 00:00:00 or the controller has not
been placed in a manual mode of operation:
•
Stabilize
: a timed state to allow the controller to enable the ECU prior to the controller cranking
the engine. This timer can be disabled if set up for mechanical engine use by changing the
ECU Stabilize Timer to 0.
•
Stopped
: a timed state where the controller is ready to start the engine manually or
automatically. This is also the state that allows changes to be saved in the Menu.
•
Standby
: a timed state that will shut off the LCD backlight, heater and CAN transceiver to
conserve battery power while the unit waits for a key press or an automatic start condition.
•
Wait To Start
: when an engine is not ready to start and sends a message across the J1939
communications stating it is not ready to start.
•
Auto Start Delay
: (available in Auto mode only) a user-defined timed state that ensures the
auto start signal is present for a desired amount of time prior to cranking the engine. During
this period, the auto start condition is ignored and must remain active throughout this delay, or
the delay is reset to zero.
