THANK YOU

for purchasing the General Engine-Module for the Graupner HoTT 2.4 system.

If you do not have the Graupner HoTT 2.4 radio system this product will not work. This product is not com-

patible with any other 2.4GHz radio system.

Please read through this entire manual before you attempt the installation and usage of your Graupner HoTT

General Engine-Module!

These operating instructions are part of this product. They contains important notes to the operation and

handling. Please take this into consideration when you pass on the product to third parties. Neglect of the

operating instructions and the safety instructions lead to expiring the warranty.

Graupner constantly work on the advancement of all remote control systems; changes of the scope of deli-

very in form, technology and equipment we must reserve ourselves therefore. Please have understanding

for the fact that from data and illustrations of this operating instructions no requirements can be derived.

Please keep these instructions for further reference!

DESCRIPTION1.

The Graupner-HoTT General Engine-Module enables the wireless monitoring of for example the battery

voltage, power consumption, motor rpm, or fuel consumption of the model in real time. The General Engine-

Module can be programmed directly with all HoTT transmitters with integrated telemetry in the transmitter

display (some models such as MC-24 with update or modiﬁcation).

The following transmitters must be programmed via SMART-BOX order No. 33700: mx-12 HoTT order

No. 4754, mx-16 HoTT order No. 4755, and mx-22 No. 4801/4802, mc-19 No. 4821 and mc-22 No. 4818

after conversion to HoTT. This differentiation between the transmitter models and the resulting operation is

explicitly mentioned at the appropriate point in the instructions (see also point 5).

For full functionality, additional sensors are necessary.

Informations available - Setup:

Battery voltage (total - single cell), Min./Max. voltage, Min./Max. cell voltage

Maximum current, used capacity

Temperature (optional Sensor 1/Sensor 2), Min./Max. Temperature

Fuel level, Min. fuel level,

RPM, Minimum/ Maximum RPM

Note: Any settings you make on the Transmitter or SMART-BOX will be stored in the General Engine-

Module only!

Since the General Engine-Module can be updated via the USB connection, you always have the latest soft-

ware and can utilize future functions or languages. Firmware updates for the General Engine-Module can

be transferred via the DATA or telemetry interface in conjunction with a PC running Windows XP, Vista or 7.

For this you also require the USB interface, Order No. 7168.6, the adapter lead, Order No. 7168.6A and a

Y-cable Order No. 3936.11 which are available separately.

The programs and ﬁles required for this are available from www.graupner.de in the Download area for the

corresponding products.

2. MOUNTING THE MODULE IN THE PLANE

Mount the General Engine-Module at an appropriate location in the model. The best way to ﬁx the General

Engine-Module with the mounting tabs or double sided tape on a wind-protected frame in the model, the

orientation of the sensor is not important.

3. CONNECTION OF SENSORS

The consumed current and capacity is measured only on connection 1 (IN) and 8 (OUT). Therefore, the

main battery for the motor (electric model - G3.5 connector) or the transmitter battery (Nitro model - JR con-

nector) must be connected to this connection. Use a connector system to replace the battery easily. If you

use a LIXX battery, the balancer can be plugged into socket 6 to monitor the individual cell voltage.

01 33610 General Engine-Module - Graupner HoTT 2.4

Caution: never connect batteries to both sockets (G3.5 and JR)!

These are inter-connected, and must only be used separately.

Note also that the input voltage is present at the JR socket at

output 8; do not connect the plug to the receiver if the voltage

is higher than the maximum permissible voltage for receiver or

servos.

Note: All negative terminals are interconnected and not galvanically seperated.

Please ensure that the continuous current does not exceed the stated maximum for the current sensor. You

should also ensure that the motor start-up current is not so high that the shunt resistors are overloaded! This

can result in a break in the power supply, which would cause the model to crash.

For this reason it is important to carry out a thorough check of the motor’s function and maximum current

drain: start cautiously, then increase to maximum load and eventually to a full battery charge, to ensure that

the current shunt resistors are not overloaded.

The “regulate current” function (see point 7.3.) can be used to limit the maximum current passing through

the model’s electronic speed controller. If the model’s current drain is above the peak current permitted for

the General Engine module, then it is essential to use this function to prevent damage to the module or a

break in the power supply.

If high peak currents are likely, you must use the more powerful General Electric sensor, Order No. 33620,

or alternatively you might prefer to manage without current measurement altogether.

When measuring power system currents please note that the voltage fall-off at the shunt resistors can place

an increased load on the speed controller, and on the speed controller’s capacitors in particular. For safety

reasons you should therefore operate the controller on one or two cells fewer than the maximum stated

cell-count, i.e. not with the full count.

Connect any additional sensors to the corresponding sockets as shown in the illustration at the top.

4. STARTING UP

Connect the General Engine-Module (socket 2) with the 3-pin lead to socket marked „T“ of the receiver. The

connector system is polarised, look for the small camfer on the edges. Never use force - the plug should en-

gage easily and fully. The sockets are labeled accordingly: black wire (-), red wire (+) and orange wire (S).

Only for transmitters under 1 „exception“ with SMART-BOX:

Install the SMART-BOX at the mounting bracket of the transmitter as shown in the ﬁgure. Connect the box

then the 3-pin lead to the transmitter. Put one end of the cable into the DATA jack on the transmitter and the

other into the jack on the right side of the SMART-BOX. The connector system is polarised, look for the small

camfer on the edges. Never use force - the plug should engage easily and fully. The sockets are labeled

accordingly: black wire (-), red wire (+) and orange wire (S).

Note: You can connect the General Engine-Module instead of the receiver directly to the jack on the right

side of the SMART-BOX. By doing this, the settings will be sent directly to the General Engine-Module

(without using the radio control system) and the programming is much faster. A power supply for the SMART-

BOX is neccessary (3.6 - 9 V), inserted on the left side. The connector system is reverse polarised, look

for the small camfer on the edges. Do not use force, the plug should click into place easily. This sockets is

labeled accordingly also. The black wire must be down (-), the red top (+).

5. OPERATION

The operation of the General Engine-Module is similar to the operation of the transmitter. You should also

read the manual of your remote control system, especially the chapter „telemetry“. The operation is done in

the transmitter menu „telemetry“ under the display SETTING & DATA VIEW. The sensor displays follow the

receiver displays (RX), i.e. the „Lipo Cell Voltage“ display follows after the last display servo test (RX SERVO

TEST). Please note: the menus can only be selected when the receiver is switched on. When you switch

the receiver on, it may take a few seconds before the receiver display becomes active and can be selected:

> symbol appears at the top right corner of the transmitter display (TX).

There may be a slight delay in the screen’s response to inputs, since all the settings are transmitted directly

to the receiver by wireless means.

Operation with the SMART-BOX:

The SMART-BOX is operated by the four buttons on the top. Switch with the ESC and ENTER keys between

the different displays. With the DEC and INC buttons you can select the parameters in the display (INC

moves the cursor down, DEC up).

Switch on the transmitter. On the startup screen appears SETTING AND DATA VIEW / MODEL SELECT.

Move the arrow cursor with the INC or DEC buttons on SETTING AND DATA VIEW and then press ENTER

to display the parameters of the transmitter, receiver and telemetry sensors and / or program it, or select

MODEL SELECT to display the telemetry data graphically (see point 9). In MODEL SELECT display no

changes are possible.

After SETTING AND DATA VIEW have chosen, the „Lipo Cell Voltage“ display is available. The sensor dis-

plays follow the transmitter (TX) and receiver (RX) displays, i.e. the „Lipo Cell Voltage“ display follows after

the last display servo test (RX SERVO TEST).

Please note: the menus can only be selected when the receiver is switched on. When you switch the recei-

ver on, it may take a few seconds before the receiver display becomes active and can be selected: > symbol

appears at the top right corner of the transmitter display (TX).

There may be a slight delay in the screen’s response to inputs using the top buttons, since all the settings

are transmitted directly to the receiver by wireless means.

6. PROGRAMMING WARNING THRESHOLDS

If you wish to carry out an adjustment, you must use the INC or DEC buttons (or ) above the screen to

select the desired parameter (e.g. page 2) by moving the arrow cursor (INC or moves the cursor down,

DEC oder moves it up). Simultaneously pressing the INC and DEC (SET) buttons switches the parameter

to be adjusted to inverse video (white on black); this indicates that it can be programmed: pressing the INC

() button at this point increases the value, pressing the DEC () button reduces the value. When the ad-

justment is complete, save the selected setting by pressing the INC and DEC (SET) buttons simultaneously;

the dark background now disappears in order to conﬁrm this action.

Display (Set Warning): shows the various „display pages“ with the possible adjustable parameters and

the associated adjustable warning thresholds (page 1, page 2, etc.). To switch between pages, press the

INC or DEC key.

Factory Set: choosing „OK“, will reset the settings of the variable module to factory settings.

The following parameters can be set separately for all displays:

Warning Time: sets whether and how long the warning signal is activated when reaching a certain value

for each display screen.

Repeat Time: sets how often the warning signal is activated when reaching a certain value for each display

screen.

Signal Tone: sets the signal tone melody. The warning sounds are combined with the warnings on the

display and the voice output. Therefore, they may not be changed.

Overview of the signal tones on page 15.

When a warning is activated, the corresponding message (eg. Min. Height) is shown inverted in the

ﬁrst row of the associated display, which then appears alternately with the display VARIO SENSOR

and the selected Signal Tone A - Z sounds.

You can stop the warning at any time by pressing one of the buttons on the top of the SMART-

BOX.

If you wish to carry out an adjustment (point 6.1 to 6.15) you must use the INC () or DEC () buttons

above the screen to select „page 1 - Save Sensor“. Simultaneously pressing the INC and DEC buttons

(SET) switches the parameter to be adjusted to inverse video (white on black); this indicates that it can be

programmed: pressing the INC () button at this point increases the value to YES. When the adjustment is

complete, save the selected setting by pressing the INC and DEC buttons (SET) simultaneously; the dark

background now disappears in order to conﬁrm this action.

If you do not want to save the adjustments, select NO.

Warning:

• Do not carry out any programming work on the sensors while the model is ﬂying, otherwise there is a real

risk that your model will ﬂy out of control while you are not concentrating on it!

• If your model is ﬁtted with two or more receivers, it is absolutely essential that you do not carry out pro-

gramming work during a ﬂight, as this can alter the settings in the receivers to which no telemetry equip-

ment is connected; in the worst case this could result in the model crashing.

For this reason always carry out programming on the ground, and check that only the receiver with con-

nected sensors is powered on.
