Most popular questions for - EngiBOX
To use EngiBOX RPM input in parallel with another RPM instrument depends on capacity of the other instrument. EngiBOX applies a 100 ohm load on RPM. Verify if the other RPM instrument is able to correctly measure RPM with a 100 ohm load applied between RPM input and instrument ground. This is equivalent to EngiBOX RPM usage in parallel with another RPM instrument.

First check if a compatible oil pressure sender is connected to the EngiBOX.

The first generation EngiBOX (model number UX0EMS00AM) is compatible with the oil pressure sender Keller 4-20 mA (Rotax P/N: 456180), which has a measuring range from 0 to 10 bar (0 - 150 psi).

The second generation EngiBOX (model number UX0EMS10AM) is compatible with oil pressure sender Keller 4-20 mA (Rotax P/N 456180) and resistive VDO sensor (Rotax P/N 956357 /  956415 ) or equivalent, both with measuring range from 0 to 10 bar (0 - 150 psi).

 

After wiring the  oil pressure sender to the EngiBOX, for the second generation EngiBOX (model number UX0EMS10AM) it is important to set the OIL P switch (on the rear side of the EngiBOX) to “ON” (position “2”) if you connected the Keller sender, or set the OIL P switch to “OFF” (position “1”) if you connected the resistive VDO sender. (see also page 10 of the User and Installation Manual).

Note: The OIL P switch is not present on the first generation EngiBOX as this model is only compatible with the Keller type sender.

 

After installation the correct sensor type needs to be selected during initialization setup.  It is possible to change the sensor type in the EngiBOX sensor menu. Check in the sensor menu if the correct  type of sender has been selected for oil pressure ( Keller 4-20mA or VDO ).

Unstable readings can be caused by a false contact of the sensor wire on the EngiBOX.

It is important to use the wire lock system to tighten all wires together that are connected to the EngiBOX (see figure 7 at page 11 of the User and Installation Manual). The wire lock system ensures that wires will not lose connection with the EngiBOX due to vibration in flight.

To see if the sensor wire is well connected  to the EngiBOX try to pull out the wire on the Engibox side, if the wire stays connected it means that it is well connected.

IMPORTANT: The oil pressure sender cannot be used in parallel with another instrument. Connect the oil pressure sender only to the EngiBOX.

IMPORTANT: Using non-compatible sensors  on the other parameter  inputs (OIL T, CHT or Coolant, EGT)  can cause false or erratic readings for the oil pressure. Make sure you connect compatible sensors on the EngiBOX as specified in the User and Installation Manual

For OIL T and CHT or Coolant use the correct resistance thermometer

For EGT use the correct thermocouple type K (ungrounded).

(To check the compatibility of the sensors please visit the FAQ: "Which sensors are compatible with Engibox?")


On the EGT value itself it might be difficult to find errors, BUT the wrong GROUNDED thermocouple sensor probe will cause erratic readings in all other engine parameters measured by the EngibOX (RPM, OIL P, OIL T, CHT).

Use a digital tester in "continuity test" mode (you can set it moving the rotor to the icon with the "speaker" symbol).

First test the digital tester itself:  Touch the red and black metallic points one with the other one and verify there is continuity (you will hear a "beep" sound).
Then test the thermocouple sensor probe with the Digital tester:
Place one contact of the digital tester on one of thermocouple wires (metallic part).
Place the other contact of the digital tester on the metallic part of the sensor probe that is in contact with engine.
If the digital tester detect that there is electrical continuity you hear the "beep" sound and you know that the thermocouple is grounded and not supported by the EngiBOX. If there is no electrical continuity you and you will not hear the "beep" sound you know that the thermocouple is ungrounded and supported by the EngiBOX.

 NO. EngiBOX supports only UNGROUNDED thermocouple sensor probes.

Power supply
Power the EngiBOX from an 10 to 35 Vdc supply. Mount on the power wire (RED) the 1A fuse holder, provided in the box, to protect against short circuits.
 
Serial Connection
The EngiBOX has serial RS232 connection ports to interface to an external device.
Note: current software 1.1.0R does not support serial in/out interface.
