Operation Instructions Section “2”
(00-02-0201)
Standard Program #01 (A94035) V12 and Later
Caution: Certain danger to human safety and to equipment
such as applied in mobile or marine application may occur if
some equipment is stopped without prewarning. In those cases
it is recommended that monitored functions be limited to
alarm-only or to alarm before shutdown.
EMS
Modes of Operation
The EMS447 and EMS448 monitor your engine/motor conditions and count
down the service reminders. When a shutdown occurs, the fuel valve will turn off
and the display will show the cause of shutdown. TOA switch must be moved to
“OFF” to reset.
The EMS447 and EMS448 have two standard modes of operation which can be
configured in the S-Numbers, these modes of operation are described as follows:
Manual Mode: When this mode is selected, the EMS performs as a
monitoring engine panel. It will alarm when faults are detected and initiate
shutdowns based on shutdown switches and gage senders. It will also remind
you when service is required for your equipment.
Automatic Mode: In the Automatic Mode, two of the shutdown inputs
available in the Manual Mode are redefined. Instead of shutdowns for V-belt
Break and Low Oil Level, automatic throttling inputs are available.
All S-numbers are used and must be configured in the Automatic mode.
Sequence of Operations
Automatic Mode of Operation
(TOA switch is in Auto, see Scrolling Main Displays, 8. Selector, p-2.)
I. A Start Signal is received
a. The start delay begins timing. If the start signal is sustained throughout
this delay, step b. is executed. If the start signal is not sustained throughout
this delay, nothing happens.
b. The prelube/glowplug output turns on throughout the prelube/glowplug delay.
c. The Fuel and Crank outputs turn on. The crank output turns on for the
adjustable crank time. It then turns off for the adjustable rest time. If the
engine starts, step d. is executed. If the engine does not start in the
adjustable number of cranking attempts, the unit will display
OVERCRANK, turn off the fuel and crank outputs, and turn on the common
fail output. If the engine false starts, the unit will wait through the adjustable
recrank delay before attempting another engine crank.
d. When the unit senses an engine RPM higher than the crank stop RPM, the
crank and glowplug outputs turn off and the following begin timing:
1. Internal hourmeter.
2. Lockout Delay. Low Oil Pressure and High Engine Temperature
shutdowns are locked out during this delay.
3. Warm-up Delay.
*e. The unit signals the engine to throttle up to the warm-up RPM.
*f. Once the warm-up delay expires, the EMS signals the engine to throttle up
to Minimum RPM and the clutch output turns on. If the engine throttling
inputs call for an engine increase or decrease, the unit will signal the engine
to respond accordingly.
NOTE: The EMS will always try to throttle the engine between the minimum and
maximum RPM set-points when at the AT-LOAD state.
II. A Stop Signal is received
a. The stop delay begins timing. If the stop signal is sustained through the
stop delay, step b. is executed. If the stop signal is not sustained through

the stop delay, the unit will continue to run.
b. The Cooldown delay begins timing.
*c. The unit signals the engine to throttle down to an idle.
**d. When engine speed reaches the clutch release RPM, the clutch output turns off.
e. When the cooldown delay expires, the following items occur:
1. Fuel valve turns off.
2. Internal hourmeter stops timing.
f. The unit is ready for another start signal. If the TOA switch is moved to the
TEST position, delay on start and stop will be ignored. The unit will start
normally and run through the sequence. When TOA switch is moved to OFF,
the unit will signal the engine to shut down without a cooldown period.
Manual Mode of Operation
In the manual mode, the unit gets its power from the ignition position of the engine
start key switch. The following sequence occurs when the unit first powers up.
I. Power is Supplied to the EMS
a. Fuel valve output turns on.
b. The “Failed To Start” Delay will begin timing (fixed to 5 minutes).
If the engine is not started within 5 minutes, “Failed To Start” is displayed
and the fuel valve is turned off.
c. When the engine speed is sensed to meet or exceed the Crank Stop setpoint, the following delays will begin timing.
1. Internal hourmeter.
2. Lockout Delay. Oil pressure and engine temperature shutdowns are
locked out during this delay. The unit must sense an engine RPM
higher than the crank stop RPM before this delay expires or it will turn
off the fuel valve and show No Speed Signal.
II. Key Switch is turned Off (power removed from EMS)
a. Fuel valve output turns off.

The graphic below shows the display and buttons.
● The ENTER (EXIT) button is used to confirm a set-point, get into and out of
a display and to acknowledge alarms.
▲ The YES (INCREMENT) button is used to scroll up the display, to select
messages, and enter value increments.
EMS-94132N page 1 of 12
▼ The NO (DECREMENT) button is used to scroll down the display, to select
messages, and enter value decrement.
Scrolling Main Displays
During normal operation, the EMS allows you to scroll through a number of
informative displays. You can manually scroll through monitored information by
pressing ▲ or ▼ buttons, or you may set the unit for automatic scrolling.
While scrolling, the EMS remains fully operational. When a shutdown occurs or a
service reminder comes due, the unit will display the corresponding information
regardless of the scrolling mode. When first powered up, the EMS will delay for one
minute before starting to scroll. When the scrolling mode is changed a 10 second
delay must time out before scrolling resumes.
To set the Automatic scroll, press the ● and ▲ buttons simultaneously. To set the
Automatic scroll mode to off, press ● and ▼ buttons at the same time. The
Automatic scroll off enables you to Manually scroll the unit. See displays listing and
explanation below:
1. MURPHY EMS
This is the first line of the title page.
2. PROGRAM #01
This is the second line of the title page. It shows which program is installed
in your unit. This information is helpful when calling for technical assistance.
3. RUN HOURS XXXX.X
This is your on board hour meter. It digitally displays the number of hours
your engine has been running. All the service reminders are based on the
elapsed time on the hourmeter.
4. BATTERY XX.X VDC
This displays your system voltage.
5. ENG SPD XXXX RPM
This displays the current engine RPM. Decisions to stop cranking and
shutdown on overspeed / underspeed are based on this number. Remember
to calibrate this in the S-numbers.
6. OIL PR XXX PSI
This displays the current engine oil pressure as sensed from an electric
gauge sender, or pressure transmitter. Shutdowns based on oil pressure
reference this number.
7. ENG TEMP XXX °F
This displays the current engine 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 in S10.
unit goes to the next state.
PRELUBE: This state occurs after the Start Delay expires. During the Prelube
state, the prelube output is turned on.
CRANK ON: This state occurs after Prelube Delay expires. During 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.
WARMUP: This state occurs after the unit senses that the engine has started.
During this state, the unit throttles the engine* to the warmup 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 clutch circuit is activated
and the unit brings the engine* speed to Minimum RPM or higher,
depending on system demand.
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 Warm-up 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 signalled to shutdown and all start
signals are ignored until the unit is reset by moving the selector to the OFF
position and then back into AUTO or TEST.
10. CHG OIL XXX HRS
This display shows the number of running hours remaining before the oil
must be changed in the engine.
11. OIL FLT XXX HRS
This display shows the number of running hours remaining before the oil
filter on the engine must be changed.
12. FUEL FLT XXX HRS
This display shows the number of running hours remaining before the fuel
filter on the engine must be changed.
13. AIR CLNR XXX HRS
8. SELECTOR - XXXX
(Replaced with MANUAL MODE when unit is used as a manual panel)
There are three positions on the selector switch that are displayed on this
line: TEST, OFF and AUTO or (TOA). When this window shows AUTO,
your TOA switch is in the AUTO position. When in AUTO, the unit is
ready to start the engine or already has started it. When this window shows
OFF, your TOA 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, your TOA 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.
9. ST: XXXXXXXXXX
ST stands for STATE. This window shows what state your controller is in.
States include the following: NOT READY, PANEL READY, START DLY,
PRELUBE, CRANK ON, CRANK OFF, 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
This display shows the number of running hours remaining before the air
cleaner on the engine must be serviced or changed.
14. SERV BAT XXXX HRS
This display shows the number of running hours remaining before the
engine cranking battery must be serviced or changed.
Service Reminders
The EMS has the above built in service reminders. When a service reminder
comes due, the EMS will stop scrolling and display the service reminder
message. If you cannot perform the service at that moment, you may press the
● (ENTER) button and the message will go away for 4 hours and normal
scrolling will resume within 10 seconds approximately.
Once you perform the service, enter the P-Numbers and select the service that is
due. Toggle the (NO) to a (YES) and the count down Timer will reset to the
number of hours programmed in the S-Numbers.
Loss of Sender Feature
If the EMS senses that a sender wire has broken or the value from the sender is
out of known bounds, the EMS will display a “Loss of Sender” alarm message
and initiate a shutdown. There are alarms for loss of temperature sender, oil
pressure sender and the magnetic pick-up speed sensor.
If you get a lost sender message for temperature or pressure, check the

S8 LOP LO SPEED (600 RPM)
CAUTION: THE S-NUMBERS CONTAIN CRITICAL
OPERATING PARAMETERS. ITEMS SET IMPROPERLY
CAN CAUSE SERIOUS DAMAGE TO THE ENGINE.
Set this to your engine idle speed (0 to 10,000). If the engine is running at
this speed, an idle for example, and the oil pressure reaches the set-point
selected in S6, the unit will initiate an automatic shutdown.
S9 LOP HI SPEED (1600 RPM)
Set this to your engine maximum speed (0 to 10,000). If the engine is
running at this speed, and the oil pressure reaches the set-point selected in
S7, the unit will initiate an automatic shutdown. The Graph below 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

S-Numbers Description and Listings
30
The S-numbers are used for customizing the controller to your specific engine.
Included in the S-numbers are variables such as crank / rest times and warm-up /
cool-down times. These S-Numbers must be set before trying to use the unit to
auto start your engine. Following is a list of available S-Numbers and a short
description of the function of each. The Factory Default values are shown in bold
parentheses; the Adjust Range values are shown in standard parentheses.
S0 CIRCLE = EXIT
Used to exit the S-number setup mode.
S1 LINE SELECT
Used to change what is displayed on the top line throughout your S-number
editing session. Your choices include: Engine Speed, Run Hours, Oil Pressure,
Engine Temperature, and Input / Output status. The input and output status
information will show an X if that particular input is active or output is ON. 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”.
S2 SPEED CALIB (120.00 PULS)
This setting (1.00 to 320.00), 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. Simply enter the
number of Pulses per revolution the magnetic pickup or alternator supplies
to the EMS. 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.
S3 OVERSPEED (2000 RPM)
This setting allows you to enter the highest speed the engine can run before
damage is caused (0 to 10,000). If the unit senses that the engine has
exceeded this speed, it will signal the engine to shutdown.
S4 UNDERSPEED (0 RPM)
If the engine speed dips to the RPM in this set-point, an automatic
shutdown will be initiated (0 to 5,000). If you do not want to use this
feature, change this variable to 0.
S5 LOCKOUT DELAY (30 SEC)
This delay (2 to 60), 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.
S6 LOP @ LOW SPD (15 PSI)
The EMS gives you two oil pressure shutdown points (0 to 1000). For
engines that develop very little oil pressure at an idle, you put a lower

Now press the ● button to set the EMS back into the Main Displays. If you forget
to exit the S-numbers menu, the EMS will exit for you after 10 minutes.
This set-point (0 to 1000), is the higher oil pressure shutdown point that is
referred to in S-number 6. 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.

set-points you entered. This graph represents the following set-points: S6 is
set to 5, S7 is set to 30, S8 is set to 600, and S9 is set to 2000.
NOTE: Once the speed reaches the high speed set-point, the oil pressure
shutdown point will not increase any higher.
S10 HI ENG TEMP (220 °F)
Adjust this setting (0 to 400), to the engine temperature you do not want to
exceed. If the unit senses an engine temperature higher than this set-point,
it will initiate an automatic shutdown.
S11 PRESS UNITS (PSI)
Select the units of pressure you would like displayed on the digital read
out. Your choices are: PSI (Pounds Per Square Inch); KPA (Kilo Pascals);
BARS (Bar); KG❐CM (Kilograms Per Square Centimeter).
NOTE: Also included are choices for selecting a bar graph of the units specified
above.
S12 TEMP UNITS (°F)
Select the units of temperature you would like displayed on the digital read
out. Your choices are: °F (Fahrenheit); °C (Celsius)
NOTE: Also included are choices for selecting a bar graph of the units specified
above.
S13 CRK STOP (300 RPM)
This RPM set-point is used to adjust where the unit releases the starter during
cranking (0 to 9999). 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.
S14 SPARE 1 TYPE (DLY ALM & SHTDWN)
S14 selects how the spare 1 terminal will handle an input signal. Your
choices are: Immediate alarm only, Immediate alarm & Shutdown,
Immediate alarm before shutdown, Delay alarm only, Delay alarm &
shutdown, and Delay alarm before shutdown. 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 (S5). The alarm before shutdown is fixed at 30 seconds. The next
option is RPM LIMIT ENABLE, when selected, an input to spare 1
terminal (spare 1 input) will signal the unit to throttle the engine* to the
setting in S34. When this input is not grounded, the unit will throttle the
engine to the setting in S33. The engine must be in AT LOAD state for this
throttle type to take effect. (This type will not function in Manual Mode.)
Your final option is LOW OIL LEVEL. When this is selected, the unit will
display LOW OIL LEVEL on the screen and shut the engine down if an
input is sensed on the SPARE 1 terminal. This is an Immediate alarm and
shutdown type.
S15 OIL PRESSURE TYPE
Enter in the type of oil pressure sensing device being used.
Your choices include: SENDER: The program would
accommodate the Murphy ES2P electric sender. XDUCER:
The program would accommodate the Murphy PXMS
pressure transducer. DIGITAL: The program would
accommodate the Murphy 20P pressure Swichgage. Factory
set to SENDER.
NOTE: LK2 #2 must be in the sender position for the “sender” or “digital”
choices. It must be in the 4-20 position for the “xducer” choice.
S16 OIL PRESSURE SLOPE
With battery power applied and no pressure applied, enter
the value displayed in the top line on the bottom line. This
should be 51 if the transducer is producing exactly 4 ma. at
zero pressure. This S# is not available if either SENDER or
DIGITAL is selected in S15. Factory set to 51.
S17 OIL PRESSURE MAX
Enter in the maximum range of the PXMS oil pressure
transducer. Example: PXMS-100 enter 100 in this set point.
This S# is not available if either SENDER or DIGITAL is
selected in S15. Factory set to 100.
S18 CHANGE OIL
Set the interval in engine running hours you wish to be
prompted to change your engine oil. Factory set to 500.
S19 CHG OIL FLTR
Set the interval in engine running hours you wish to be
prompted to change your engine oil filter. Factory set to 500.
S20 CHG FUEL FLT
Set the interval in engine running hours you wish to be
prompted to change your engine fuel filter. Factory set to 1000.
S21 SERV AIR CLN
Set the interval in engine running hours you wish to be
prompted to service your engine air cleaner. Factory set to 10.
S22 SERV BATTERY
Set the interval in engine running hours you wish to be
prompted to service your cranking battery. Factory set to 120.
NOTE: After service reminder time values have been set, the
new values will not take effect (become active) until they have
also been acknowledged in P-Numbers P-15 through P-19.
S23 PANEL MODE
You have two options: MANUAL or AUTOMATIC. When
Manual is selected, the unit will function as a standard
engine monitoring panel. You must manually start the
engine and throttle it to the desired speed. It will initiate
shutdowns when faults are detected. Set-points relating to
the Automatic mode will no longer display when this mode
is selected. When AUTOMATIC is selected, the unit will
perform all engine control automatically. Factory set to
MANUAL.
S24 WARMUP DLY
You can adjust this variable to the number of seconds you
want your engine to warm-up before it engages the clutch
and throttles up to an at load condition, or goes to the “at
load” state (adjustable from 1 to 300 seconds). Factory set
to 30.
S25 COOLDOWN DLY
You can adjust this variable to the number of seconds you
wish to cool down your engine before it shuts off after a
stop signal is received (adjustable from 1 to 300 seconds).
Factory set to 60.
S26 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.
S27 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.
S28 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.
S29 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.
S30 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.
S31 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.
S32 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.
S33 MIN ENG RPM
Minimum engine RPM is the speed at which your engine
must run for it’s driven equipment to start performing work.
For example, in a pumping application, minimum engine
RPM is the speed at which an engine must run for fluid to
begin being pumped. Set this variable to that speed. Factory
set to 900
S34 MAX ENG RPM
Maximum engine RPM is the speed at which engine driven
pump performance peaks. If the engine exceeds this speed,
pump performance starts to deteriorate. This would be at the
peak of a pump curve, for example. Set this set-point to that
peak speed. For auto throttling at load, the controller will
vary your engine speed between minimum and maximum
RPM. Factory set to 1600.
S35 WARMUP RPM
* When equipped with Murphy AT-67207 or other throttling device.
EMS-94132N page 4 of 12
You can set a specific speed you would like the engine to
run during the warm-up time delay in this set-point. Consult
your engine manual for the optimum warm-up speed.
Factory set to 700.
S36 RATE INC RPM
This set-point is used to customize how fast or slow you
wish the unit to increase the engine speed during throttling.
Experiment with this number until the desired throttling is
achieved. Factory default for this set-point is 10 RPM per
second. Factory set to 10.
S37 RATE DEC RPM
This set-point is used to customize how fast or slow you
wish the unit to decrease the engine speed during throttling.
Experiment with this number until the desired throttling is
achieved. Factory default for this set-point is 10 RPM per
second. Factory set to 10.
S38 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 800.
S39 STRT/STOP TYPE
This set-point allows you to configure the type of automatic
start / stop inputs you will use. If this set-point is adjusted to
OPL, a momentary input to terminal 1(447), (31 on 448),
(analog input 4 as a switch input) will cause a start and a
momentary input to terminal 15(447), (34 on 448) (analog
input 5 as a switch input) will cause a stop. The momentary
input must be maintained for the length of the start or stop
delay. If this set-point is adjusted to 1 MAINTAIN CNTCT,
a start input must be present the entire time a run condition
is required on terminal 1(447), (31 on 448), (analog input 4
as a switch input). When this input is taken away, the unit
interprets this as a stop signal. If this set-point is adjusted to
2 MAINTAIN CNTCT, a start input must be present on both
1(447), (31 on 448), (analog input 4 as a switch input) and
15(447), (34 on 448), (analog input 5 as a switch input)
before the unit will acknowledge a start. A stop is initiated
after both inputs are removed. Factory set to OPL
START/STOP.
S40 THR MIN PULS
This set-point is used to further customize the way the unit
throttles your engine. Higher numbers cause the throttling
outputs to stay active for longer periods of time when the
unit demands an increase or decrease in the throttling. If it
hunts around the set-point, lower the setting. If the engine
never reaches the set-point, raise the number. Factory set to
700.
S41 THR FDBK DLY
This set-point adjusts the amount of time in quarter seconds
that the controller waits to sample the change made from the
previous throttle pulse. Lower numbers cause less of a wait
than larger numbers. If the system pressure, for example,
takes quite a long time to change based on speed changes
from the engine, this set-point should be increased. On the
other hand, if the system pressure reacts quickly with changes
in engine RPM, lower the set-point. Factory set to 2.
S42 THR SEN SITVY
This set-point adjusts the throttle 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 unit from
overshooting or undershooting a set-point. If it hunts around the
set-point, lower the setting. If the engine never reaches the setpoint, raise the number. Factory set to 700.

P-Numbers Description and Listings
The P-numbers are used to acknowledge service reminders and accessing the shutdown
history list. Following is a list of P-number information and acknowledgments.
P15 ACK CHG OIL
This setting allows the user to acknowledge that they have changed the oil
in the engine as prompted by the unit. When this setting is toggled from
NO to YES, the unit resets the counter and will not prompt the user again
until the selected number of running hours has elapsed.
P0 CIRCLE = EXIT
Used to exit the P-number editing mode.
P1 LINE 1 SELECT
Used to change what is displayed on the top line throughout your P-number
editing session. Your choices include: Engine Speed, Run Hours, Battery
Voltage, Oil Pressure, and Engine Temperature.
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:

General Wiring Precautions
There are several precautions you can take on initial installation to increase reliability. Many of these steps may take a few extra minutes to do at the time of
installation; however, they can also save 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 EMS447 /448 (Automatic mode) or Off-On switch (Manual Mode), run your positive and negative wiring directly to the
battery posts. 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 Hook Up
Solid wire transmits vibration and is more likely to crystallize and break when it is subjected to movement and or vibration.
5. 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 electric “noise” coupled into the microprocessor.
6. Separate VAC and VDC Wiring
Never run AC and DC handling wiring together. AC signals may get coupled into the control circuits leading to erratic operation.
7. Special Precaution for Spark Ignition Systems
Spark ignition systems produce high voltage and cause high frequency interference. Precautions must be taken to protect the EMS. All wiring, and especially
sender and shutdown wiring must be routed away from the ignition and spark plug wiring. Resistor spark plugs and spark plug wires reduce electrical interference
and are recommended for these applications.
8. Use Shielded Cable on Magnetic Pick-up
Shielded cable is recommended for connecting the magnetic pick-up to the unit. This helps prevent signal loss and 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.
