OPERATION MANUAL
FOR USE WITH: PROGRAM # A97127.V6 DATE: October 3, 2001
GENERAL INFORMATION
DESCRIPTION
The EMS Controller is a microprocessor based engine controller with built-in service reminder features. It will
automatically warn you when certain service items need to be performed and will signal your engine to shut down if a
fault is detected.
There are two types of EMS controllers this program will function in. The EMS448 and EMS447. The EMS448 is
a complete panel and the EMS447 is in an European type din package for mounting in a larger panel.
The system is accessed through three push-buttons and a back-lit, dot-matrix liquid crystal display. A more
detailed description of operator functions can be found in the operating instruction section.
SENSOR INPUTS
The EMS Controller accepts several different types of sensor inputs. Below is a list of which types are accepted.
See the wiring hookup drawing for terminal details.
Electric Gauge Senders. These inputs allow you to use standard Murphy electric gauge type senders for
pressure and temperature.
Digital alarm inputs. These inputs are negative grounding type inputs. Typically, external shutdown switches are
wired to these inputs. They can include vibration, low pressures, high temperatures, and low levels.
Frequency input. This input is an optically isolated speed sensing input. You may get your speed signal from
either a magnetic pickup or the tachometer post of your alternator.
OUTPUTS
The EMS448 controller has a total of seven (7) open collector transistor outputs. One (1) of these can be selected
as an input. All outputs are rated for 200 ma.
The EMS447 controller has a total of three (3) relay and four (4) open collector transistor outputs. One of the
transistor outputs can be selected as an input. The relay outputs are rated for three (3) amps and the transistor
outputs are rated for 200 ma.
OPERATING THE EMS CONTROLLER
The EMS Controller is very simple to operate. Once the Setup numbers have been configured for your operation,
the unit will automatically perform its duties with very little user interface.
The front plate has three push-buttons for scrolling through information, changing set-points, and acknowledging
alarms. See the Operating Instructions section for more information.

SPECIAL FEATURES
START / STOP TYPES
The Controller has a set point for selecting the type of automatic start / stop the controller will perform. This
input can be configured through the Ss. Your choices include: CLOCK, PSI, REMOTE and CLK/PSI. If one
type is selected the controller will ignore the other types. The following describes the start / stop types:
CLOCK: When this is selected the controller will monitor the clock start / stop times. It will have the ability to
start up to three times a day as programmed in the P#s. The start times are independently
programmed for each day of the week.
REMOTE: When the set point is set to REMOTE a start input must be present the entire time a run condition is
required on terminal 1. When this input is taken away, the unit interprets this as a stop signal.
PSI: If this set point is adjusted to PSI, the unit will start and stop based on the PSI START and PSI
STOP set points set in S#s.
CLKIPSI: If this set point is adjusted to CLK/PSI, the unit will start and stop based on the PSI START and PSI
STOP set points set in S#s and the clock start times in the P#s.
SITE START J
When the controller is first set up at a site for operation, the operator can force a site start. This means,
regardless of the automatic start selected the controller will start and run. It will throttle the engine to maintain
the system pressure. It will run as long as the site start run time is programmed for. After the controller has
completed this run time the controller will auto stop the engine and resume running in the auto sequence as
programmed by the user.
SERVICE REMINDERS
The Controller will have field adjustable service reminders. The user can program the engine running hours for
the controller to enunciate the service reminders. These service reminders could represent time to change the
oil filter or air filter etc.. To clear the Service Reminder prompt simply go into the P#s described in the Operation
section and acknowledge the Service Reminder.
SHUTDOWN TYPES
There is an S# for some of the shutdowns. This set-point lets you pick the way you want the controller to the
shutdown. Your choices include: Immediate alarm only, Immediate alarm & Shutdown, Immediate alarm before
shutdown, Delay alarm only, Delay alarm & shutdown, Delay alarm before shutdown and Low Suction Pressure.
These types of shutdowns are self explanatory. An immediate type alarm, shutdown or both will be processed
whenever the input is active. A delay type alarm, shutdown or both will be processed after the Lockout Delay
has expired. The shutdowns or alarms will be recorded in the alarm / shutdown history. The following
shutdowns’ types are field selectable:
1. Oil Pressure.
2. Coolant Temperature
3. Coolant Pressure
4. Spare 1 Shutdown
The following shutdowns are fixed to be shutdowns only:
1. High Discharge Pressure
2. Low Discharge Pressure
3. High Pump Temperature
SPARE 1 TYPE SHUTDOWN
The Controller has a spare shutdown input. This input can be configured through the S#s. This set-point lets you
pick the way you want the controller to handle an input on the spare 1 terminal. Your choices include: Immediate
alarm only, Immediate alarm & Shutdown, Immediate alarm before shutdown, Delay alarm only, Delay alarm &
shutdown, Delay alarm before shutdown and Low Suction Pressure. These types of shutdowns are self

11. H20 TEMP XXX °F
This displays the current engine jacket water temperature as sensed from an electric gauge sender. The unit
will signal the engine to shutdown if this temperature reading exceeds the shutdown point selected.
12. XXXXXXXXXXXXXXXX
There are two positions on the selector switch that are displayed on this line: SELECTOR IN AUTO, and
SELECTOR IN OFF. When this window shows AUTO, your TEST - OFF - AUTO switch is in the AUTO
position. When in AUTO, the unit is ready to start the engine. Depending on the type of start programmed in
the controller by the user, when the controller is in AUTO this window shows CLOCK START, REMOTE, PSI
START, CLK/PSI START and SITE START when an auto start sequence is initiated. When this window shows
OFF, your TEST - OFF - AUTO switch is in the OFF position. The unit will not initiate an auto start with the
switch in the OFF position. If the switch is moved to the OFF position while the engine is running, the unit will
signal the engine to stop. When this window shows TEST START, your TEST - OFF - AUTO switch is in the
TEST position. When the switch is flipped to TEST, the unit will start the engine as if a start signal had been
received; regardless of the start / stop contacts.
13. ST: XXXXXXXXXX
ST stands for STATE. This window shows what state your controller is in. These states include the following:
NOT READY, PANEL READY, START DLY, PRELUBE, CRANK ON, CRANK OFF, RECRANK DLY,
WARMUP, AT LOAD, SHUTDOWN, STOP DLY and COOLDOWN.
NOT READY: This state occurs when the selector is in the OFF position. It means that the panel is not ready
to run in Automatic mode.
PANEL READY: This state occurs when the selector is in the AUTO position and no shutdowns have
occurred. It means that the panel is ready to run in Automatic mode.
START DLY: This state occurs when a start signal is sensed and the start delay is timing. The start signal
must be present throughout this delay before the unit goes to the next state.
PRELUBE: This state occurs after the Start Delay expires. During the Prelube state, the unit energizes the
prelube circuit for the prelube delay time.
CRANK ON: This state occurs after the Prelube Delay expires. During the Crank On state, the unit energizes
the starter circuit and attempts to start the engine.
CRANK OFF: This state occurs after the Crank On state if the unit senses that the engine has not started.
During the Crank Off state, the unit removes power from the starter circuit to cool off the starter before another
cranking attempt is made.
RECRANK DLY: This state occurs if a false start occurs. A false start occurs when the engine speed rises
above crank disconnect RPM and then drops back below. This delay will not allow the controller to re-engage
the starter. The purpose is to allow the engine to stop moving before allowing the controller to re-engage the
starter. This state can only occur during the lockout delay.
WARMUP: This state occurs after the unit senses that the engine has started. During this state, the unit
throttles the engine to the warm-up RPM and stays at this engine speed until the Warmup Delay expires. The
Lockout Delay also begins timing when the Warmup State begins.
AT LOAD: This state occurs after the Warmup state concludes. It can also occur if a start signal is received
during the Cooldown state (see Cooldown below). When the At Load state first begins, the Generator regulator
output is energized to enable the generator.
STOP DLY: This state occurs when a stop signal is sensed and the stop delay is timing. The stop signal must
be present throughout this delay before the unit goes to the next state.
COOLDOWN: This state occurs after the Stop Delay has expired. During the Cooldown state, the unit throttles
the engine to an idle. As the engine RPM passes through the Clutch Release RPM, the unit will deactivate the
clutch circuit. If a start signal is received during the Cooldown state, the unit will switch to the At Load state and
ignore the Warmup state.
SHUTDOWN: This state 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 selector to the OFF position and then back into
AUTO or TEST.

INPUT / OUTPUT STATUS
Note: The input / output status information will show an X on an |/O if that particular input is or
output is active. If there is no input or the output is OFF, the unit will display an O. This can be
used for testing wiring before starting the engine. For more information, see the section titled
“Double Checking Your Wiring”. |
S-2: Set Time Minutes. To adjust the minutes portion of the Real Time Clock.
S-3: Set Time Hours. To adjust the hours portion of the Real Time Clock.
S-4: Set Date Day. To adjust the day portion of the date display.
S-5: Set Date Month. To adjust the month.
S-6: Set Date Year. To adjust the year.
S-7: Set Day of Week. Adjusts day of week Sunday through Saturday. Day advances with date.
S-8: SPEED CALIB: This setting is used to calibrate the speed signal so that the unit will display
engine RPM. This setting must be adjusted for items such as crank stop RPM and OVERSPEED
RPM to work. Simpiy enter the number of Pulses per revolution the magnetic pickup or alternator
supplies to the unit . Another way to set this variable is to get the engine running at a known RPM
and then change the number until the top line matches your known RPM. The resulting number is
the pulses per revolution. Factory set to 208.
5-9: OVERSPEED: This setting allows you to enter the highest speed the engine can run before
damage is caused. If the unit senses that the engine has exceeded this speed, it will signal the
engine to shutdown. Factory set to 2000.
S-10: LOCKOUT DELAY: This delay is used to ignore conditions such as low oil pressure when the
engine first starts to allow the pressure time to reach its normal operating range (adjustable from 2
to 2,000 seconds). Factory set to 30.
S-11: AT LOAD DLY: Set this variable to the amount of time you would like the Low Discharge
Pressure shutdown ignored after warm-up. This allows the system to build discharge pressure
with the engine AT LOAD before arming the shutdown. Factory set to 300.
S-12: LOP @ LOW SPD: The EMS Controller gives you two oil pressure shutdown points. For engines

that develop very little oil pressure at an idle, you put a lower shutdown setting in this set-point.
The unit automatically changes the shutdown point between the Low Speed Shutdown point and
the High Speed Shutdown point. Factory set to 15.
S-13: LOP @ HI SPD: This set-point is the higher oil pressure shutdown point that is referred to in
number 12 above. This is the point that you want the engine to shutdown during normal high
speed engine operation. By shutting down the engine at a higher oil pressure, you can avert
damage that could be caused by waiting to shut down the engine at the lower set-point needed to
accommodate an idle. Factory set to 30.
S-14: LO OIL PR TYPE: This set-point lets you pick the way the controller will handle an indication of
low oil pressure. Your choices include: IMMEDIATE ALARM ONLY, IMMEDIATE ALARM AND
SHUTDOWN, IMMEDIATE ALARM BEFORE SHUTDOWN, DELAY ALARM ONLY, DELAY
ALARM & SHUTDOWN, DELAY ALARM BEFORE SHUTDOWN, LOW SUCTION PRES and
OVERLOAD / UNDERLOAD. An immediate alarm is processed when the input is active. A delay
alarm is processed after the lockout delay. Factory set to IMM ALM ONLY.
S-15: LOP LO SPEED: Set this to your engine idle speed. If the engine is running at this speed, an
idle for example, and the oil pressure reaches the value in the LOP @ LOW SPD set-point, the
unit will initiate an automatic shutdown. Factory set to 600.
S-16: LOP HI SPEED: Set this to your engine maximum speed. If the engine is running at this speed,
and the oil pressure reaches the value in the LOP Q HI SPD set-point, the unit will initiate an
automatic shutdown. Factory set to 1600.

The Graph above shows how the set-point changes between your high speed set-point and low
speed set-point. As the engine speed increases, the unit automatically raises the oil pressure
shutdown set-point along a straight line between the two set-points you entered.
S-17: HI WATER TMP: Adjust this setting to the engine jacket water temperature you do not want to
exceed. If the unit senses a temperature higher than this set-point, it will initiate an automatic
shutdown. Factory set to 220.
S-18: HI TEMP TYPE: This set-point lets you pick the way the controller will handle a high temperature
indication. Your choices include: IMMEDIATE ALARM ONLY, IMMEDIATE ALARM AND
SHUTDOWN, IMMEDIATE ALARM BEFORE SHUTDOWN, DELAY ALARM ONLY, DELAY
ALARM & SHUTDOWN, DELAY ALARM BEFORE SHUTDOWN, LOW SUCTION PRES and
OVERLOAD / UNDERLOAD. An immediate alarm is processed when the input is active. A delay
alarm is processed after the lockout delay. Factory set to IMM ALM ONLY.
S-19: H20 PSI TYPE: This set-point lets you pick the way the controller will handle an input on the low
coolant pressure terminal. Your choices include: IMMEDIATE ALARM ONLY, IMMEDIATE
ALARM AND SHUTDOWN, IMMEDIATE ALARM BEFORE SHUTDOWN, DELAY ALARM ONLY,
DELAY ALARM & SHUTDOWN, DELAY ALARM BEFORE SHUTDOWN, LOW SUCTION PRES
and OVERLOAD / UNDERLOAD. An immediate alarm is processed when the input is active. A
delay alarm is processed after the lockout delay. Factory set to DLY ALM ONLY.
S-20: WARMUP DLY: You can adjust this variable to the number of seconds you want your engine to

Factory set to 60.
S-22: PRELUBE DLY: If you have the requirement for prelube or possibly a glowplug, you can use this
delay. Set in the number of seconds you wish the unit to turn on this output before it initiates a
crank. Factory set to 1.
S-23: ENG STRT DLY: Set this delay on engine start to the number of seconds that the start signal
must be present before the unit accepts it and initiates an auto start sequence (adjustable from 1
to 300 seconds). Factory set to 1.
S-24: ENG STOP DLY: Set this delay on engine stop to the number of seconds that the stop signal
must be present before the unit accepts it and initiates a stop sequence (adjustable from 1 to 300
seconds). Factory set to 1.
S-25: CRANK TIME: Set this delay to the desired amount of time you want each engine cranking
attempt to last. Consult your engine manual for recommended cranking and resting times
(adjustable from 1 to 300 seconds). Factory set to 10.
S-26: REST TIME: Set this delay to the desired amount of time you want each rest period between
cranking attempts to last. Consult your engine manual for recommended resting and cranking
times (adjustable from 1 to 300 seconds). Factory set to 10.
S-27: RECRANK DLY: This delay is used to adjust the amount of time the unit will wait for the engine
to stop moving before attempting another crank if a false start occurs. A false start is when the
engine starts but then dies before the LOCKOUT DELAY has expired (adjustable from 1 to 300
seconds). Factory set to 10. |
S-28: CRK STOP RPM: This RPM set-point is used to adjust where the unit releases the starter during
cranking. Set this to the RPM the engine attains just as it starts. This way, the starter is not
engaged unnecessarily after the engine starts. You must also set this set-point to the speed you
release the starter while cranking. This is how the unit senses whether the engine is running or
not. You will get a NO SPEED SIGNAL shutdown if this is adjusted to high. Factory set to 300.
S-29: CRK ATTEMPTS: Set the number of attempts you would like the controller to try an engine start.
If the engine fails to start after the number of attempts you have selected, it will fail the engine and
display OVERCRANK on the front display. This shutdown requires a manual reset. Factory set
to 6.
S-30: MIN ENG RPM: Minimum engine RPM is the speed at which your engine must run for its’ driven
equipment to start performing work. For example, in a pumping application, minimum engine
RPM is the speed the engine must run for the fluid to start being pumped. Set this variable to that
value. Factory set to 900.
S-31: MAX ENG RPM: Maximum engine RPM is the speed at which the engine driven pump
performance peaks. If the engine exceeds this speed, pump performance deteriorate. This would
be at the peak of the pump curve, for example. Set this set-point to that peak speed. For auto
throttling at-load the controller will vary the engine speed between minimum and maximum RPM.
Factory set to 1600.
S-32: WARMUP SPEED: This is the engine RPM the controller will throttle the engine to during warm-
up. Consult the engine manual for the optimum warm-up speed. Factory set to 700.
S-33: RATE INC RPM: This set-point is used to customize how fast or slow the controller will increase
the engine RPM while throttling. Experiment with this number until the proper throttling is
achieved. Factory setto 10.
S-34: RATE DEC RPM: This set-point is used to customize how fast or slow the controller will
decrease the engine RPM while throttling. Experiment with this number until the proper throttling
is achieved. Factory set to 10.
S-35: CLUT ENG RPM: After warmup, the unit brings the engine up to at least minimum RPM. While it
is throttling up, it passes through the clutch engage RPM and engages the clutch. Set this point
to the RPM you would like the unit to automatically engage the clutch after warm up. Factory set
to 900.
File Name: a9/127op.doc Page 13 of 24
OPERATION DIRECTIONS
S-36: CLUT REL RPM: During cooldown, the unit brings the engine to an idle. While it is throttling
down, it passes through the clutch release RPM and drops out the clutch. Set this point to the
RPM you would like the unit to automatically release the clutch during Cooldown. Factory set to
900.
S-37: THR MIN PULS: This set-point is used to further customize the way controller will throttle the
engine. Higher numbers cause the throttling outputs to stay active for longer periods of time
when the system is throttling either up or down. If the engine is hunting then lower the value. If
the engine never reaches the set-point then increase the value. Factory set to 700.
S-38: THR FDBK DLY: This set-point is used to adjust the amount of time the controller waits to
sample the change made by the previous throttle pulse. If the system pressure, for example
takes a long time to change based on engine speed changes, this set-point should be increased.
However, if the system pressure responds quickly then set the variable to a smaller value.
Factory set to 2.
S-39: THR SENSITVY: This set-point adjusts the throttler sensitivity when it closes in on the desired
set-point. Higher numbers cause it to make more coarse signal adjustments when approaching a
set-point than lower numbers. This set-point is used to keep the controller from overshooting and
undershooting the a set-point. Lower the number if the controller is hunting. Raise the value if
the unit doesn’t achieve the desired set-point. Factory set to 700.
—————
S-40: SET ADJ DLY: This delay allows the controller to stop making adjustments to the engine RPM
for this delay. It allows for a settling time after making a speed adjustment. Factory set to 2.
S-41: SPARE 1 TYPE: This set-point lets you pick the way the controller will handle an input on the
spare 1 terminal. Your choices include: IMMEDIATE ALARM ONLY, IMMEDIATE ALARM AND
SHUTDOWN, IMMEDIATE ALARM BEFORE SHUTDOWN, DELAY ALARM ONLY, DELAY
ALARM & SHUTDOWN, DELAY ALARM BEFORE SHUTDOWN, LOW SUCTION PRES and
OVERLOAD / UNDERLOAD. An immediate alarm is processed when the input is active. A delay
alarm is processed after the lockout delay. Factory set to DLY ALM & SHTDWN.
S-42: CHANGE OIL: Set the interval in engine running hours you wish to be prompted to change your
engine oil. Factory set to 500.
S-43: CHG OIL FLTR: Set the interval in engine running hours you wish to be prompted to change your

(become active) until they have also been acknowledged in the P-Numbers below.
S-47: START/STOP: This set-point allows you to configure the type of automatic start / stop inputs the
controller will use. The choices include CLOCK, PSI, REMOTE and CLK/PSI. Factory set to
CLOCK.
S-48: SITE START: This set point allows for the user to force a start that overrides any other start signal
and run for the site run time period. Use the up arrow to switch the display from OFF to ON and
the site start operation will begins. When the site run time expires the controller will initiate a stop
sequence and the display will switch back to OFF. Factory set to OFF.

There are several precautions you can take on initial installation to reduce chances of failure over time. Many of these
steps may take a few extra minutes to do at the time of installation; however, they can also save many headaches in
the future. We strongly recommend that you follow these precautionary steps.
1. Suppression Diodes
Place suppression diodes across all inductive loads. These loads typically include pilot relays, solenoid valves, starter
solenoids, etc. This helps increase contact life and eliminate a source of electrical interference.
2. Wire power leads directly to battery Post.
When hooking your power supply to your Test- Off - Auto switch (AUTOMATIC MODE) or OFF-ON switch (MANUAL
MODE), run your wiring directly to the battery post. This helps minimize noise generated from battery chargers and
alternators.
3. Pilot excessive loads.
Many of the outputs on the EMS Controller are rated for low current, control type loads. Do not run high current loads
directly to the unit.
4. Use stranded wire for hookup.
Solid wire transmits vibration and is more likely to crystallize and break when it is subjected to movement.
5. Separate AC and DC wiring.

OPERATION DIRECTIONS
Never run AC and DC handling wiring together. AC signals may get coupled into the control circuits leading to erratic
operation.
6. Wire standby battery charger directly to battery.
Standby chargers must be wired directly to the battery. Failing to do this may result in erratic operation due to
electronic "noise" coupled into the microprocessor.
7. Special precautions for spark ignition engines.
Magnetos and ignition coils produce high voltage and cause high frequency interference. The EMS Controller is
designed to filter out much of this interference; however, precautions must be taken to protect the unit. Sender and
shutdown wiring must be routed away from the magneto and spark coil wiring. Resistor spark plugs and spark plug
wires reduce electrical interference and may also be required in especially "noisy" environments.
8. Use shielded cable on magnetic pickup.
Shielded cable is recommended for connecting the magnetic pickup to the EMS Controller. This helps prevent signal
loss and the possible coupling of electrical interference into the relatively sensitive speed sensing circuit. The shield
should only be grounded on one end.
Remember, proper care during installation will help your EMS Controller live a long and trouble-free operating life. If
for any reason you have questions during installation, feel free to give us a call.
DOUBLE CHECKING YOUR WIRING
The EMS Controller has built in diagnostic information for confirming your wiring before you attempt to auto start your
engine. The diagnostic information is found in the S-numbers under S1 LINE 1 SELECT. The factory default line 1
display shows the engine RPM.
By scrolling through the displays, you will see the following:
