1. GENERAL DESCRIPTION

1.1. INTRODUCTION

This manual describes the physical, mechanical and electrical features and functions of the TL-3724
Combined Engine Instrument.

1.2. EQUIPMENT DESCRIPTION

The TL-3724 is a complete engine monitor for measuring all quantities of an engine.
The TL-3724 facilitates seeking the cause of an engine default or damage, with use of the SchecK®
method for storing the measured values into the memory.
The TL-3724 checks all measured values at two levels - for a warning and an alarm limit signalization.
When the alarm warning has been activated, the instrument will display a Service message after the next
turn-on to inform the user on the exceeded some value.
The instrument incorporates a 2,000-line long-term memory and SchecK memory (see page 5-1) for
storing the measured values at 0.1 to 60 second sample rate.
The TL-3724 incorporates a Memory / Info button for displaying the maximum measured values and
other information.
It is possible to download the measured values from the instrument via the serial cable RS-232c into your
PC.

The placement of the values on the display, as well as setting the quantity you want to
show, can be changed at any time with use of the Windows program delivered with the
instrument.

The producer of the engine instrument and its distributor reserve the right not to announce
the correct code as this code helps to decide whether the guarantee can be applied.

1.3. TECHNICAL SPECIFICATIONS

The producer guarantees all stated technical parameters only when the instrument is installed by an
authorized service or an aircraft works.

2. INSTALLATION

2.1 INTRODUCTION

Careful planning and consideration of the suggestions in this section are required to achieve the desired
performance and reliability from the TL-3724.

2.2 RACK CONSIDERATION

Plan a location that gives the pilot complete and comfortable access to the entire keypad and that is plainly
visible from the pilot’s perspective. Check that there is adequate depth for the rack in the instrument panel.
A place away from heating vents or other sources of heat generation is optimal.

2.3 INSTALLATION OF ACCESSORIES

Make sure that the sensor connection corresponds with the set configuration of the instrument according to
the Instrument Configuration. In other case, contact an authorized distributor for the correct sensor setting.
Connection of sensors and other parts must be done properly to avoid any damage.

Connect the cables into the connector and use the connector cover.
Secure the incoming leads to prevent their effect on the connector
in the vertical direction.

6. OPERATION MANUAL

6.1 After-installation Check

After the installation, check the correctness of all
connected inputs and turn the instrument on.
After turning the instrument on, check the
correctness of the measured values.
All set values will show on the display. If the
symbol [---] shows, it means that a sensor might
not be connected or might not work.

If the instrument has not been purchased as a part of the engine, the configuration is
required. Do the configuration with use of the Windows program delivered with the
instrument.

If some of the measured values is out of range (the symbol [---] shows on the display)
or if some of the measured values is incorrect, do not start the engine!
If you started the engine, the signalization of exceeding the limits might be activated,
and the incorrect values would be recorded into the memory.

6.2 Engine Name

Make sure that the name of your engine is shown
correctly on the display. Also check whether the
correct local unit for measuring temperature in °C
or °F has been set.

quantities will show.

Do not manipulate, connect or disconnect the sensor while the engine is on,
otherwise extremely high values could be recorded.

6.4 „READY“ to Take-Off

The „READY“ message shows when the engine
has reached the operational temperature after the
start-up. This message will show only if the correct
temperature datum has been set.

6.5 „OVER“ Limit Message

The instrument checks the measured values at two
levels. The first one, Warning signalization informs
the pilot by blinking on exceeding the limit and that
more attention should be paid to the measured
values (the yellow field). If the measured value
exceeds the Alarm limit (the red field), blinking will
continue and the „OVER“ message will show.
After the next turn-on of the instrument,
the „SERVICE“ message will show.

The limit value check is activated immediately after the set rotation value for
the activation is reached. Only the minimum oil pressure check is activated after
5 seconds to allow the oil circuit to get pressurized.

6.6 „SERVICE MESSAGE“

If the set limit values have been exceeded, the
„SERVICE MESSAGE“ shows after turning the
instrument on.This information will disappear after
15 seconds and then the instrument get back to the
normal measuring mode.
By pressing the „INFO“ button, the pilot has to find
out which measured item has been exceeded and
eliminate the possible defect.

6.7 Deleting „SERVICE MESSAGE“

When deleting the „SERVICE MESSAGE“ has
been enabled in the instrument via the PC control
software, the „SERVICE MESSAGE“ can easily
be deleted by pressing the „INFO“ button and
turning the instrument on at the same time.
After that the „SERVICE DELETED“ message
shows on the display.

6.8 „LOW POWER“ Message

This message will show always when voltage drops
under the operational limit. This may happen during
the engine start up etc. In this case, wait till the
instrument gets back to the normal measuring
mode.

6.9 „SYSTEM ERROR“ Message

If the automatic internal circuit check found out an
error in the instrument or a data integrity defect,
the „SYSTEM ERROR“ message will show on the
display.

Do not try to repair the instrument yourself. Contact a distributor or the producer
with the 2-digit number specifying the error.
