Installation and Operations Manual

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

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.

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-throttling options:
Floats, and Transducer. A backlit operator-interface offers many easy-to-
use 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 additional wiring and enclosure
modifications.
User Interface and Navigation
This section defines how to navigate through the EMS PRO LITE 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.

STOP = In the “MAN” (manual) mode this initiates a stop sequence.
THROTTLE INCREASE = In the “MAN” (manual) mode this increases
engine speed.
THROTTLE DECREASE = In the “MAN” (manual) mode this decreases
engine speed.

and your changes are saved.
Key Switch
The controller accepts inputs from a 3-position key switch. The three
positions are AUTO, OFF, and MAN:
Input
Description
AUTO
Functions described in the “Auto Start/Stop Sequence” of this
document.
OFF
Disconnects control power to prevent the engine from starting or
continuing to run through the control panel. The OFF position provides
an immediate shutdown whenever the key switch is placed in this
position while the engine is running in either the automatic or manual
modes.
MAN
Functions as described in the “MAN Start/Stop Sequence” in this
document.

Section 40 00-02-0787
2015-03-23 ~ 3 ~
Stop Switch
The Stop Switch is the large red push button on the front face of the
EMS PRO LITE. When it is pushed in, it latches closed. If the Stop
Switch is pushed in, power to the controller is OFF. The Stop Switch
must be pulled out to power the controller.
Screens Displayed
During normal operation, the controller allows you to scroll through a
number of informative screen displays by using the
membrane keys. Below are several example screens.

The following are the different states the controller can
execute during operation:
ST: (STATE XXXX)
This text line displays states the controller can execute
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 DELAY occurs when a start signal is active
and the start delay is timing. 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 selected 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.

ST: (STATE XXXX),
continued
•CRANK OFF occurs when cycle cranking begins.
During this state, the crank output is turned OFF.
•RECRANK DELAY occurs if the engine speed
drops below the “crank stop” set point before the
“shutdown lockout delay” expires.
•WARMUP occurs after the engine starts. During this
state, the controller throttles the engine to the warm-
up RPM until this delay expires.
•AT LOAD occurs after the Warm-up delay expires.
The low discharge pressure shutdown is armed
when this delay expires.
•FILL MODE occurs after the Warm-up delay
expires. Auto throttling to the minimum RPM set
point occurs during this state.
•STOP DELAY occurs when a stop signal is active
and the stop delay is timing. The stop signal must
remain active throughout this delay before the auto
sequence can continue.
•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 is
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.

Section 40 00-02-0787
2015-03-23 ~ 12 ~
If you are using the EMS PRO LITE on an Interim Tier 4 engine, please
read and understand the information for the following S-numbers: S73,
S74, and S75 in the S-number table, page 22. Also, read and understand
the following information and steps to set up Tier 4 Emission options.
The controller displays the SOOT level on the display when the engine
has been de-rated and/or when regeneration (regen) is required to return
to normal service. You must set S73 (Tier Rating) to Tier 4 for these
options to be available.
•If S74 (Tier State) is set to Auto DPF Regen, the ECU
performs a regen automatically. This only occurs if the
ECU conditions allow.
•If S75 (Request DPF Regen) is set to YES, the controller
commands the ECU to perform a regen. This only occurs
if ECU conditions allow.
•If S75 (Request DPF Regen) is set to NO, Inhibit Regen is
active and no regen occurs.
To use the controller on a Tier 4 engine, follow the steps below:
1. Access the S Menu by pressing [Menu].
2. Press the [Up or Down Arrow] to scroll to the correct
Entry Code (See Entry Code Supplement for Entry
Codes).
3. Press the [Up or Down Arrow] until S73 (Tier Rating)
is displayed in the menu and press [Enter].
4. Press the [Up or Down Arrow] until TIER 4 is
highlighted and press [Enter].
5. Press the [Up or Down Arrow] until S74 (Tier State)
is highlighted and press [Enter]. The default value is
set to INHIBIT. To select Auto DPF Regen use the
[Up or Down Arrow] to highlight the text and press
[Enter].
To use the Request DPF Regen feature, follow these steps (If all the
conditions for a regen to occur are not met, this request could be ignored
by the ECU):
1. Access the S Menu by pressing [Menu]
2. Press the [Up or Down Arrow] and scroll to the
correct Entry Code (See Entry Code Supplement for
Entry Codes).
3. Press the [Up or Down Arrow] until S75 (Request
DPF Regen) is displayed in the menu and press
[Enter].
4. Press the [Up Arrow] until YES is highlighted and
press [Enter].
