Introduction
The EMS-3 is a multifunction engine information display and early warning engine monitoring system. It has been
specifically designed to monitor crucial vehicle information, and in the event of any engine irregularities, it will alert the
driver by means of a visual and audible alarm.
ith its array of advanced features, the EMS-3 is an indispensable unit for the discerning vehicle owner. Costly
maintenance bills can easily be avoided by the prevention of major engine problems before they occur.

3.1 EGT (Exhaust Gas Temperature) / Pyrometer
Few things will damage or kill a diesel engine like excessive exhaust gas temperatures, yet the EGT gauges are not
standard equipment fitted by the diesel engine manufacturers and are only available as an after market add on unit.
The EMS-3 can alert the driver of any situations where the EGT gets too high which could cause irreparable engine and
or turbo charger damage. The EGT can be affected by a too rich air/fuel mixture or an air intake problem. Air intake
problems could include a blocked/partially blocked air intake, a dirty air cleaner, high water temperatures etc. The EMS- 3
EGT gauge could also save on fuel costs as the EGT is directly related to the air/fuel mixture.
The EGT probe can be installed on the exhaust manifold or immediately after the turbo. It is recommended to install the
EGT probe before the turbo as temperature differences of up to 200ºC (392ºF) between the inlet and outlet of the turbo
has been measured under heavy loads.
Under normal driving conditions the EGT may vary between 250ºC (482ºF) and 650ºC (1202ºF). For most vehicles the
alarm limit should be set to 720ºC (1328ºF). Please be aware that pushing the engine hard or driving up a steep hill, could
cause the exhaust gas to exceed this temperature. If you have prolonged high EGT then it is recommended to
immediately have it checked out by a qualified mechanic.
Madman custom built thermocouple EGT probes are specifically designed for automotive use. The Madman EGT probes
can handle temperatures up to 1300ºC (2372ºF).
The EMS-3 can use K-Type or J-Type thermocouples to display the EGT temperature. The EMS-3 contains precision
instrumentation electronic circuitry to amplify and linearize the thermocouple sensor. The EMS-3 also has built in cold
junction compensation to make the EGT reading as accurate as possible.
3.2 Battery Volts
The EMS-3 can measure the vehicle's battery voltage in the range of 8V to 30Vdc and has built in over-voltage and
reverse voltage protection. The EMS-3 contains a programmable low/high voltage alarm to automatically catch alternator
failures, drive belt failures and bad batteries.
3.3 Pressure Display
The EMS-3 uses standard automotive pressure senders to display the pressure. The EMS-3 supports 2, 5 and 10 Bar
VDO senders, SENDO MPS 2, 5, 7, and 10 bar senders, 0.5-4.5V senders, 4-20mA pressure senders or a custom user
definable pressure sender curve.
3. Oil Pressure Switch Message
The EMS-3 can also be used to display a warning message from a switch type oil pressure sender. These senders can be
of a NO (Normally Open) or a NC (Normally Closed) type sender. The oil pressure switch uses the analog input
channel.
This message is displayed when there is an oil pressure alarm from the switch (NO/NC)
on the oil pressure sender.
Madman EMS-3 Operating Manual Page 5
3.5 Temperature Display
The EMS-3 uses standard automotive temperature senders to display the temperature. The EMS-3 also contains fail safe
temperature inputs to alert the user when the sender has been disconnected or faulty. The EMS-3 supports 120 and 150
VDO senders, a precision temperature sender, Echlin TS920SA or a custom user definable temperature sender curve.
3.6 Coolant Level Detector
The coolant level detector is an engine coolant level early warning system. It uses an AC signal probe excitation to
accurately determine the absence/presence of coolant level. The coolant level detector can use inexpensive probes such
as stainless steel screws to determine the coolant level. It also features a fail safe input circuit. The coolant level detector
can also be used with float level type sensors (These senders must be of a normally open type). The coolant level switch
must connect to the vehicles negative supply terminal when the coolant level is at an acceptable level.
The coolant level detector has a programmable switch time. This means that the level alarm from the coolant level switch
must be activated for at least the programmed time before an alarm is activated. This prevents false alarm messages
when driving over rough terrain etc. The EMS-3 also has a programmable coolant level threshold which allows the user to
fine tune the trigger point.
This message is displayed when there is a coolant level problem.
3.7 Service Timer Expired Message
This timer is set in engine hours and it will count down to zero. The purpose of this function is to assist you in determining
remaining hours until maintenance will be required.
A maximum of 9999 hours can be entered as a service interval. An alarm message will
be displayed and the appropriate alarm output will be activated (if enabled).
3.8 Hour meter
The hour meter is a useful instrument to display actual engine running time for routine maintenance. The hour meter is
displayed as hours and fractional minutes in 1/10 of an hour resolution (increments every 6 minutes). The hour meter can
be reset to zero in the “TIMERS SETUP” menu. The hour meter updates its internal minute counter every minute. If the
unit is turned on and off for a period of less then a minute, then the hour meter will not increment its internal registers.
The hour meter can be triggered by an ignition on signal or by a rise in battery voltage which signals that the engine is in
fact running.

.3 Analog CH1 to CH Setup
The 4 analog channels are universal analog input channels that can be used for pressure, temperature etc.
Only “CHANNEL 1” Setup is shown below, follow the same steps for Channel 2, 3 &
.3.1 Pressure Setup
Mode:
Select the function for the analog channel. Options are “PRESSURE”, “TEMP” or “OFF”.
Type:
Select if you are using a resistive, voltage or current pressure sender.
If the “R SISTIV ” pressure sender is selected
In most cases resistive sensors require a biasing voltage to work properly. Inside the EMS3
unit is a small block of DIP switches, The switch associated with the required channel must be
in the ON position to enable the sensor to work correctly. By default, CH1 + CH2 are ON and
CH3 + CH are off. Failure to set the DIP switch will not cause damage but will cause false
readings.
