Murphy PowerCore®20 (MPC-20)
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 is flexible in many aspects and 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;
•use the same controller on 12VDC or 24VDC systems;
•use as auto start or manual start controller;
•use as manual throttle 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
The MPC-20 Controller, while reprogrammable, follows a standard operating sequence. This operating sequence
is a set of machine states that happen in a predetermined order. Machine states can be set to zero if not needed
or adjusted to fit the application. The following states 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: This is a timed state to allow the controller to enable the ECU or any senders without
warnings or errors. This timer can be disabled if set up for mechanical engine use.
•Stopped: This is a timed state where the engine is ready to be started manually or automatically.
•Standby: This is a timed state that will shut off the LCD backlight, heater and CAN transceiver to
conserve power while the unit waits for a key press or an automatic start condition.
•Auto Start Delay: (available in Auto mode only) The auto start condition is ignored and must
remain active throughout this delay, or the delay is reset to zero.
•Check Safe To Start: This is a non-timed state that will check to ensure the engine can start
safely.
•Auto Stop Delay: (available in Auto Mode only) The auto stop condition is ignored and must
remain active throughout this delay, or the delay is reset to zero.
•Minimum Run Time: This timer is only active using auto start and with all auto start types except
local key and clock. Local stop key will also initiate the stop sequence before the timer expires, if
pressed.
•ECU Stabilize Timer: This delay begins timing when the controller is powered up, Spindown or
Standby delays have expired. During this delay, the ECU enable output is turned on. The ECU
output turns off when the Standby, ETS or Spindown delays begin timing.
•Prestart Delay 1: (available in Auto Mode only) After an auto start condition has been accepted
by the controller, this delay begins timing, and the prestart output turns on. When this delay
expires, the output is turned off, and the auto sequence continues.
•*Prestart Delay 2 (precrank): (available in Auto Mode only) After an auto start condition has
been accepted by the controller, this delay begins timing, and the prestart output turns on. When
this delay expires, the output is turned off, and the auto sequence continues. During this delay,
the controller checks for faults, J1939 com, etc.

Section 40 00-02-0994
2016-06-28 - 12 -
•*Prestart Delay 2 (crank through): (available in Auto Mode only) After an auto start condition
has been accepted by the controller, this delay begins timing, and the prestart output turns on.
When this delay expires, the output remains on, and the auto sequence continues. The output
turns off when the engine actually starts. During this delay, the controller checks for faults, J1939
com, etc.
•Crank: This is a timed state to try and start the engine.
•Crank Rest: This is a timed state to rest the starter between cranks in case the engine did not
start during the crank state.
•False Start Check: This is a non-timed state that will ensure the engine stays above the crank cut
RPM after cranking.
•Warm-up: (available in Auto mode only) This is a timed state that will allow the engine to
change from idle to desired warm-up RPM after starting. Warm-up will only set as low as the
minimum RPM set point.
•Line Fill 1: (available in Auto mode only) This is a timed state that will exit if the timer times out
or the pressure set point for this state is reached.
•Line Fill 2: (available in Auto mode only) This is a timed state that will exit if the timer times out
or the pressure set point for this state is reached.
•Running Loaded: This is a non-timed state that the controller will stay in until a stop condition
occurs.
•Cool-down: (available in Auto mode only) This is a timed state that will allow the engine to run
at a desired speed to cool down before allowing to go into a stopped state.
•Energize to Stop: This is a timed state that will control an output in order to stop the engine.
•Spindown:The time allotted for the engine to stop all revolutions and be in a stopped state with
no frequency.
•Post Crank Lockout Delay (setup): This delay begins timing when the engine actually starts.
During this delay, the selected function is ignored. When this delay expires, the selected function
is armed. During the duration of this delay, the selected function can cycle from active to not
active and not reset the delay.
•Post Warm-up Lockout Delay (setup): This delay begins timing when the warm-up delay expires.
During this delay, the selected function is ignored. When this delay expires, the selected function
is armed. During the duration of this delay, the selected function can cycle from active to not
active and not reset the delay.
•Bubble Lockout Delay (setup): This delay begins timing when the selected function is active. If the
selected function is removed during this delay, the delay resets to zero. If the selected function
remains active throughout this delay, the selected action will occur.

User Interface
The keypad on the MPC-20 is comprised of 11 tactile buttons. This section describes the functions of each
button.
The buttons have the following functions:
•Start Key – Allows the operator to start sequence in Manual Mode or initiate an auto start
sequence when in Auto Mode.
•Stop Key – Allows the operator to initiate the stop sequence in either mode of operation. A
single button press in auto will initiate an auto stop. As a safety feature, when the stop button
is pressed twice or held (in auto mode), the controller will skip the cool-down state and (upon
shutting down) will place itself in manual mode to eliminate an auto crank condition. This
happens if the autostart condition is still present.
•Auto Key – Allows the operator to change from Auto to Manual or Manual to Auto Mode by
press-hold for 3 seconds.
•Alarm Silence Key – Allows the operator to silence the internal siren when an alarm or
shutdown is present on the controller.
•Manual Throttle Increase Key – Allows the operator to manually increase the engine throttle
in Manual Mode.
•Manual Throttle Decrease Key – Allows the operator to manually decrease the engine throttle
in Manual Mode.
•Menu Key – Allows the operator to get into and out of the menus.
•Back Key – Allows the operator to move back one step while in the menu.
•Enter Key – Allows the operator to enter a value in the menu when selected and is used to
acknowledge internal and external alarm/shutdowns.
•Up Key – Allows the operator to navigate up through the menu and page forward on the main
pages.

Main Menu
The MPC-20 controller is incredibly versatile within the menu structure. The operator is able to change many
parameters and settings from the face without the need of a PC tool, if desired. The controller has to be in its
stopped state in order to change a setting in the menu. (The Tier 4 menu is the exception.) Described below are
the main sections of the controller’s menu. Cycling power to the controller is recommended after making
changes to set points.
(Main Menu, page 1)
System
The controller System menu provides the operator with the ability to set the Date/Time, Units, Language,
Brightness, Contrast, Service Reminders and several other system settings. Review System under the Menu
Glossary section of this manual for a full list and definition of each setting.
Engine Settings
The Engine Settings menu allows the operator to establish common, user-configurable parameters that would be
changed from factory-default settings when pairing the controller to an engine. This menu allows the operator to
choose whether the engine is J1939 or mechanical; the engine’s speed source; the minimum and maximum RPM
the operator requires/allows the engine to run; the RPM step size; warm-up/cool-down settings; and other common
engine settings. Review Engine Settings under the Menu Glossary section of this manual for a full list and definition
of each setting.
Advanced Engine Settings
The Advanced Engine Settings menu allows the operator to set up the less common user-configurable parameters
that are not in the Engine Settings menu and which would be changed from factory-default settings when pairing
the controller to an engine. This menu allows the operator to set items such as the J1939 address claim for the
controller, ECU Source Address, ECU hour select, crank attempts, crank disconnect speed, clutch
engage/disengage speed, run to destruct mode and other user-specific engine settings. Review Advanced Engine

increase/decrease, throttle Inc/Dec pulse time, throttle RPM deadband and other parameters pertaining to throttling
of the engine. Review Throttle under the Menu Glossary section of this manual for a full list and definition of each
setting.
Input / Output
The Input/Output Menu allows the user to establish the I/O needed for the application. This includes Digital Inputs,
Analog Inputs, Relay Outputs and Digital Outputs. This menu is tied to other aspects of the controller menu such
as Auto Start Functions, Auto Throttling Methods, Analog inputs for Mechanical Engine setup, Warning / Shutdown
functions and all outputs needed for starting/controlling the engine and alerting the user.
The Digital Inputs of this menu can be configured from the face of the controller to accept three types of inputs.
•High, B(+)
•Low, B(-)
•Open
The Analog Inputs of this menu can be configured from the face of the controller to accept one of four types of
senders without having to order a new controller or arrange jumpers on the hardware.
•Resistive
•4-20mA
•0-5VDC
•B(-) for additional Digital Inputs
The Outputs are configurable for the operator to choose which output function to use with the desired output
type as shown below.
•Relay [10A, Form C]
•Digital Out [200mA, 5VDC]
•Digital Out [2A, B(+)]
•Digital Out [1A, B(-)]
NOTE: Although the functionality exists to set all analog and digital inputs to the same
function, Enovation Controls strongly advises against this.
