In order to consistently bring you the highest quality, full-featured
products, we reserve the right to change our specifications and designs
at any time.
Enovation Controls has made efforts to ensure the
reliability of the EMS PRO LITE and to
recommend safe use practices in system
applications. Please note that in any application,
operation and controller failures can occur. These
failures might result in full control outputs or other
outputs that might cause damage to or unsafe
conditions in the equipment or process connected
to the EMS PRO LITE.
To follow good engineering practices, electrical
codes, and insurance regulations requires that you
use independent external protective devices to
prevent potentially dangerous or unsafe
conditions. Assume that the EMS PRO LITE can
fail with outputs full ON, outputs full OFF, or that
other unexpected conditions can occur.
BEFORE BEGINNING INSTALL ATION O F
THIS MURPHY PRODUCT:
• This installation information is intended for all EMS
PRO LITE Series models. A visual inspection of
this product before installation for any damage
during shipping is recommended.
• Disconnect all electrical power to the machine.
Failure to disconnect all electrical power
connections before welding can result in damage
to the panel and/or its components.
• It is your responsibility to have a qualified
technician install the unit and make sure
installation conforms to local codes.
• Observe all Warnings and Cautions in each
section of these instructions.
• The EMS PRO LITE is designed for use in
industrial environments. There might be potential
difficulties in ensuring electromagnetic
compatibility in other environments due to
conducted as well as radiated disturbances.
• Please contact Eno vatio n Cont ro ls im mediately if
you have any questions.
IMPORTANT! Improper use and
operation of electronic products can be
dangerous. It is required that point-ofoperation guarding devices be installed and
maintained. All such devices must meet
OSHA and ANSI Machine safety standards.

NOTES
Introduction
The EMS PRO LITE is a customizable pump-controller designed with
dewatering and irrigation applications in mind.
EMS PRO LITE offers field-adjustable operating parameters without the
need for a laptop computer. It can support both mechanical and J1939
electronic engines.
This unit offers selectable auto start/stop with auto-thr o ttli ng opt ions:
Floats, and Transducer. A backlit operator-interface offers many easy-touse performance-enhancing features. The display is readable day or
night.
The EMS PRO LITE is ideal for use with a remote modem or in a
SCADA system offering Modbus® RTU protocol on either the RS232 or
RS485 port.
NOTE: Your EMS PRO LITE must be modified to use these
ports – changes include addit ion al wiri ng and enc l os ure
modifications.
User Interface and Navigation
This section defines how to navigate through the EM S PRO LIT E user
interface. It explains the screens and keys used to modify settings and
how each works.
Membrane Keypad
The membrane keypad is made up of eight buttons. All of the functions
for the EMS PRO LITE can be set using these eight buttons.

during operation:
• NOT READY occurs when the key switch is in the
OFF position. This is seen briefly while the controller
is powering ON. No sequence occurs in this state.
• PANEL READY occurs when the key switch is in
the AUTO position and no shutdowns have
occurred. The controller is waiting for an auto start
condition to occur.
• START D ELAY occurs when a start signal is active
and the start delay is tim ing. The start signal must
remain active throughout this delay before the auto
sequence can continue.
• PRESTART occurs after the start delay expires.
During the Prestart state, the prestart output is
turned ON.
• WAIT FOR ECU occurs after the Prestart delay
expires if “ECU” is selec ted in the engine type.
During the WAIT state, the unit allows the ECU to
warm-up prior to cranking.
• CRANK ON occurs when cycle cranking begins.
During the crank-on state, the crank output is turned
ON.

• COOLDOWN occurs after the Stop Delay has
expired. During the Cool down state, the controller
throttles the engine to an idle.
• SHUTDOWN occurs if a shutdown condition i s
detected. Reasons for shutdown include low oil
pressure, high engine temperature, overspeed, etc.
During this state, the engine is signaled to shutdown
and all start signals are ignored until the state is
reset by moving the key switch to the OFF position
and then back to AUTO or MAN.

Tier 4 Emissions*
*Murphy products are compliant with requirements for U.S. EPA Emission
Standard ‒ Tier 4 Interim and EU Emissions Standard ‒ Stage IIIB for diesel
engines. These engines, when fitted with a DPF (Diesel Particulate Filter), can
self-clean the filter of particulates. The self-cleaning process is known as
Regeneration. EMS PRO LITE offers two tier levels: Tier 3 and Tier 4. The
following S-numbers are associated with emission control actions: S73 (Tier
Rating), S74 (Tier State), and S75 (Request DPF Regen) and can be seen in the
S-number table on page 22.
NOTICE: Enovation Controls does not control the
Emissions ECU, please consult with your engine
manufacturer for specific emissions operation.
