OPERATION OF THE ELECTRONIC INSTRUMENT

PANEL FOR 3500 ELECTRONIC ENGINES


2/13

This is a standard panel on 3500 electronic engines . Whether its

a 3508 , 3512 or 3516 B or C model engine . It has 3 modules

for the operator to monitor the engine as its running . The main

Display module is the brain of the panel . It receives the data

information from the ECM (computer ) and sends the informationto the appropriate gauge in the gauge cluster . It also has a digital

read out for the rpm ( tach ), hour meter , load factor , fuel

consumption and all the gauge readings for pressure and

temperatures . An operator , or mechanic , can get a lot of

information just by scrolling through gauges to check engine

operation to see if theres a problem present .

As I discuss the components of the panel , I will follow it with a

picture showing the components location . On the front of the

panel you will find 3 modules on the left , the first one being the

Main Display Module , this module has the digital read out windowand all the warning and shutdown lights . You will find 2 rows of

light indicators. The top row is the RED lights , which are for

critical issues going on with the engine . The lower row is the

AMBER colored lights , which are warning lights , such as low

water level , low fuel psi , high water temp and so on .

Main Display ModuleThe top row of lights , from left to

right , STOP LIGHT , LOW BATTERY

VOLTAGE , OVERSPEED ,

OVERCRANK and NOT IN AUTO .

These lights will blink RED the

lower set of lights are AMBER ,

for WARNINGS . From left to right

, LOW OIL PSI , HIGH WATER TEMP ,

LOW WATER TEMP , LOW WATER

LEVEL AND LOW FUEL PSI . Low

fuel psi is on the ADEM III

electronic system

The gauge module below the EMS module has the gauges for

GA-5 thru GA-8 .Ga-5 exhaust temp ( left/right bank )

ga-6 air filter restriction ( left/right )

ga-7 fuel filter restriction

ga-8 oil filter restriction

When ga-6,7 and 8 reach 15 psi restriction , it will set off the

STOP LIGHT to start blinking , but it will not show a diagnostic

code if you go to MODE 2 on the EMS module . You can see the

problem on CAT ET . You can see the problem by looking at ga-6

thru ga-8 . If the needle on the gauge is to the right of the centermark in the gauge , the filter for that gauge needs to be replaced .

Most of the time its ga-7 . Fuel filter restriction . This is the fuel

filters on the engine NOT THE RACOR filters .

Top row left to right

Ga-5 exh temp ( left/right bank )

Ga-6 air filter restriction ( left/right )

Ga-7 engine fuel filter restriction

Ga-8 engine oil filter restriction

To switch from LEFT to RIGHT BANK FORGa-5 and Ga-6 , use the toggle switch to

the left of the module . Flip up for LEFT

BANK and flip down for RIGHT BANK .


9/13

To scroll through the panel and read the gauges , on the left side

of the panel you will see 3 toggle switches . The top one is to

scroll , the middle one , push up to clear a code , push down to

get to the different Modes of display .

Mode 1 - Gauge readingsMode 2 - diagnostic codes

Mode 3 Selftest, tattle tail

Mode 4 US/Metric

Mode 5 Harness code

The bottom toggle switch is to select LEFT bank or RIGHT bank

when looking at the exhaust temp of air filter restriction .


10/13

Push up and watch the

digital display in the EMS

module , it will switch

from RPM to the Hour

meter . The hour meter

will show an hour glass on

the left side .

Watch the digital display area and

push down to get to the mode you

want to look at . You will see 1,2,3,4

and 5 . When you see the mode

number you want , let go of the

toggle switch .

On Ga-5 and Ga-6 , up for

LEFT BANK or down for

RIGHT BANK

To see the hour meter ,

battery voltage , diagnosticcodes with the engine not

running , turn the start

selector switch to either the

AUTO or COOL DOWN/STOP

position and it will power up

the panel

Go to Mode 1

Hold the middle toggle switch down until you see the number 1 in the

EMS digital display and let go

The first thing you will see will be the word

LOAD this is the load factor on the engine .

Push the top toggle switch up to scroll through MODE 1 . The next thing

you see will be FL-0 , this will show you the current fuel consumption as

the engine is running . Push the scroll switch up again and you see FL-1

, this will show total fuel consumption from the time the engine was new

until current time . Push up again and see Ga-1

Engine oil pressure . Every time the display changes , let go of the scroll

toggle switch . Next will be Ga-2 , engine jacket water temp

Ga-3 , Engine battery voltage

Ga-4 , engine fuel pressure and so on until you get to Ga-8 . Scroll up

again and it will take you bake to the LOAD factor .

Mode 2

Hold down the middle toggle switch and when number 2 shows , let go of the

toggle switch . If all you see is (---) , this means there is no diagnostic codes

present . If the STOP LIGHT on the EMS is blinking , check the Ga-6, 7 and 8 .If there is a code present , it will first show 030 or 036

be sure to pay attention to these two code numbers . Its very important . 030 is

a DATA related code and 036 is a component related code . They can have a 6digit code number following them , but it will mean different things . After you

see 030 or 036 , it will be followed by a 6 digit number , example , 0168 02 .

Push the top toggle switch up to scroll through mode 2 to see if there is more

than one code . If there is only one present , when you scroll through it , it will

show the word END On the end of the panel , you will find a chart with mostof the code numbers you will see in the digital display area of the EMS . If you

have to call a service tech , tell them the complete code number like 036 0168

02 , or whatever the codes are you see .
