5. Installation

IMPORTANT: For a correct installation and temperature readings, consult the EngiBOX User &

Installation manual, paragraph 2.2 Connections & Wiring, available at avionics.avmap.it.

IMPORTANT: First install the thermocouple sensor on the engine (STEP 1). After the thermocouple

sensor is installed on the engine, proceed to connect the thermocouple sensor bare wires to the

EngiBOX (STEP 2).

STEP 1: Installation on Rotax 2 stroke and 4 stroke carbureted engines

IMPORTANT: Grease the connection threads with Loctite ANTI-SEIZE type material to ensure

trouble free removal and protect against rust, corrosion, seizing and galling.

The engine exhaust gas temperature is monitored by means of thermocouple sensors on the

engines exhaust manifold.

Check if the connection thread M8x1 for attachment of the thermocouple sensor is already provided

in the exhaust bend.

Case

Connection thread M8x1 is

provided in the exhaust bends

Connection thread M8x1 is

NOT provided in the exhaust

bends

NOTE: On Rotax 914 engine series the connection thread M8x1 for attachment of the thermocouple

sensor are already provided in the 4 exhaust bends. On the other Rotax engine series the presence

of exhaust manifold and connection threads may vary per engine and aircraft model.

STEP 2: Connection to the EngiBOX

The EngiBOX can connect to the thermocouple sensor in order to monitor the exhaust gas

temperature of the engine.

The AvMap EGT probe comes with 2 bare wires:

1. Red wire = +/+

2. Green wire = -/-

Connect the red wire to the respective EngiBOX terminal input +/+ TEMP

Connect the green wire to the respective EngiBOX terminal input -/- TEMP

Connect the thermocouple sensor to the connection thread M8x1

of the desired exhaust bend by screwing it in and fasten it tight.

Install the M8x1 weld boss, that is delivered in this package

together with the thermocouple sensor, on the exhaust bend.

Consult the Rotax installation manual and the aircraft

manufacturer that installed the engine on the aircraft for

identifying the correct position on the exhaust bend for exhaust

gas temperature readings.

After identifying the correct position make a 12mm (0.47")

diameter hole in the exhaust bend and insert the M8x1 weld boss

in the exhaust bend 12 mm (0.47") diameter hole and attach the

M8x1 weld boss to the exhaust bend by welding it.

Connect the thermocouple sensor to the M8x1 weld boss by

screwing it in and fasten it tight.
