Introduction
This document is designed to familiarize a user withthe 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 timedstate toallowthecontrollerto enabletheECUprior tothe controllercranking
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.

Software Release: [App: 02.09.10039.00; Config: 2.9.20024; Built in PowerVision Configuration Studio Version:

•Prestart Delay 1: (Auto Only or Auto/Manual) after a 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.
•Check Safe To Start: a non-timed state that will check to ensure the engine can start safely.
•Minimum Run Time: 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.
•*Prestart Delay 2 (precrank): (Auto Only or Auto/Manual) after a 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.
•*Prestart Delay 2 (crank through): (Auto Only or Auto/Manual) after a 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 through crank. The output turns off when the
engine starts. During this delay, the controller checks for faults, J1939 com, etc.
•Crank: a timed state for when the controller turns on the Crank output to start the engine.
•Crank Rest: a timed state to rest the starter between cranks in case the engine did not start
during the crank state.
•False Start Check: a non-timed state that will ensure the engine stays above the crank cut
RPM after cranking.
•Warm-up: (available in Auto mode only) a timed state that will allow the engine to run at a
desired warm-up RPM after starting.
•Line Fill 1: (available in Auto mode only) a timed state that will allow the engine to run at a
desired Line Fill RPM and exit if the timer times out or the pressure set point for this state is
reached. This is commonly used when filling a discharge line to a desired pressure when a
lower RPM is needed prior to throttling to maintain a pressure.
•Line Fill 2: (available in Auto mode only) a timed state following Line Fill 1 that will allow the
engine to run at a desiredLine Fill RPM and exit if the timer times out or the pressure set point
for this state is reached. This is commonlyused when filling a HoseReel to a desired pressure
when a lower RPM is needed prior to throttling to maintain a pressure.
•Running Loaded: a non-timed state that the controller will stay in until a stop condition is
initiated in the controller.
•Auto Stop Delay: (available in Auto mode only) a user-defined timed state that ensures the
auto stop signal is present for a desired amount of time prior to entering the shutdown
sequence. During this period the auto stop condition is ignored and must remain active
throughout this delay, or the delay is reset to zero.
•Cooldown: (available in Auto mode only) 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: a timed state that will control an output in order to stop the engine. This
state will only work if the controller is shut down using an auto stop or the local stop key. If the
controller loses battery power, this state will not be initiated for energize to stop.
•Spindown:time allotted for the engine to stop all revolutions and be in a stopped state with
no frequency. The controller will repeat the Spindown state if the controller continues to get
RPM when the timer times out.

User Interface
The keypad on the MPC-20-R2 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 if the start signal remains present.
•Auto Key –allows the operator to change from Auto to Manual or Manual to Auto Mode.
The MPC-20-R2 requires an acknowledgement from the user to place in auto mode from
manual.
•Alarm Silence Key –allows the operator to temporarily silence the internal siren, common
alarm output and acknowledge active faults when an alarm or shutdown is present on the
controller.
•Manual Throttle Increase Key –allows the operator to manually increase the engine
speed in Manual Mode.
•Manual Throttle Decrease Key –allows the operator to manually decrease the engine
speed in Manual Mode.
•Menu Key –allows the operator to get into and out of the menu.
•Back Key –allows the operator tomove back one step in themenu without saving a value.
•Enter Key –allows the operator to save a desired value or setting in the menu.
•Up Key –allows the operator to navigate up through the menu and page forward in the
main page views.

Accessing the Menu
The MPC-20-R2 has three menu security levels to restrict users from making changes after installation. The
security levels are Low, Medium and High. One may consider these security levels as user, technician and
OEM. The low level security only has a small number of items a user can access. The medium level security
has all the low level menu items plus others a technician may change while in the field. The high security level
has the entire menu visible to the user or OEM.
To access the menu, press the menu key. Review section Passcodes to understand the menu level preset in
the MPC-20-R2.The following screen will display to enter the passcode: [Low=1111; Medium=5311;
High=3482].
The passcode will be entered left to right. Utilize the up and down arrows, and press the Enter button after
each correct number. If you enter the wrong passcode, it will reset the display to 0000, allowing you to restart
the entry process.
Main Menu
The MPC-20 controller is incredibly versatile within its 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 save 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.

Auto Start/Stop Functions Defined
There are eight automatic start/stop types in the MPC-20-R2 and are shown relative to the application chosen
as shown in the previous section. Each is detailed below:
Single Contact Start/Stop
The Single Contact Start/Stop occurs when a remote contact is active for auto start and inactive for auto stop.
Think of this as a toggle switch, on or off for remote starting the engine. Requires one digital input for this
start/stop type.
Local Start Key Start/Stop
The Local Start Key Start/Stop is used to remove any other auto start/stop types within the controller, if they
are not needed. This auto start type still allows the controller to run through the auto states of the controller.

Software Release: [App: 02.09.10039.00; Config: 2.9.20024; Built in PowerVision Configuration Studio Version:

2019-06-13
The operator must press the green start key to activate the auto start sequence. The red stop key will initiate
the auto stop sequence in the controller.
Two Contact Maintained Start/Stop (commonly known as Floats)
The Two Contact Maintained Start occurs when both contacts are active for an auto start and both contacts
are inactive for an auto stop (not momentarily). Depending on whether the application is emptying or filling,
the start float will need to be positioned above the stop float or below the stop float. It requires two digital
inputs, one for start and one for stop.
Two Contact Momentary Start/Stop
The Two Contact Momentary Start occurs when the start input is active momentarily for an auto start, and the
stop contact is momentarily active for an auto stop. The start/stop inputs may have start and stop timer
associated. Check this area in the Advanced Engine Settings under Timers. It requires two digital inputs, one
for start and one for stop.
(Pressure, Level, Flow or Temperature) Transducer Start/Stop
A transducer is neededfor any of theseauto start/stop types and setup in the Input/Outputmenu under Analog
Inputs. Set points for the desired auto start/stop type selected will be in populated menu in the application
configuration menu allowing the operator to enter the appropriate values needed in the application. Warnings
and shutdowns for any of these types are in the Advanced Engine Settings under Warnings and Shutdowns.
Auto Throttling Functions Defined
There are five automatic throttle functions in the MPC-20-R2 and are shown relative to the application chosen
as shown in the application configuration section. Each is detailed below:
Running Loaded Throttle
The Running Loaded Throttle function allows the controller, when in auto, to runthe engine at adesired speed
between the minimum and maximum speed settings of the controller. This speed is set in the application
configuration menu when this throttle function is chosen.
(Pressure, Level or Flow) Transducer Throttle
A transducer is needed for any of these auto throttling functions and set up in the I/O menu. Set points for the
desired auto throttling function selected will be in populated menu in the application configuration menu
allowing the operator to enter the appropriate values needed to maintain a pressure, level, or flow in the
application. Warnings and shutdowns for any of these types are in the Advanced Engine Settings under
Warnings and Shutdowns.
Local Throttle Input
The Local Throttle Input throttles the engine between the minimum and maximum RPM set points when using
the 0-5V analog input function.
