The UBG-16 was designed for use in a single engine aircraft. (For twin engines, use two UBG-

16’s.)

On the back of the UBG-16 are three circular connectors. As seen in

the diagram to the right:

The first 1 to 7 channels of the LEFT 16-pin connector are used to

monitor EGT’s. Any remaining channels may be used to monitor

other functions.

The first 1 to 7 channels of the RIGHT 16-pin connector are used

to monitor CHT’s. Any remaining channels may be used to

monitor other functions.

The small 9-pin connector connects the instrument to power,

ground, display intensity control, RS232 Recorder and any warn-

ing devices.

The UBG-16 comes with three preassembled wire harnesses which simply plug into the three

circular connectors at the back of the instrument. Two of the wire harnesses are identical. One

will be used to connect the EGT probes to the UBG-16 and the other will be use to connect the

CHT probes to the UBG-16. The wire harnesses were assembled with only enough cables to

accommodate the EGT and CHT channels. Any additional temperature measurement (TIT, OAT,

Carb Temp, Cowl, etc.) requires a Type K thermocouple extension cable be added to the appropri-

ate harness. Any desired function such as RPM, M.P., Oil Pressure, Fuel Pressure, Fuel Flow,

Gyro Vacuum, Volts, Amps, etc., requires an Electronics International Functional Module be

added to the appropriate harness.

The UBG-16 does not require any programming before installation. All setup can be accomplished

on the face of the instrument. The UBG-16 does not use any internal batteries, so once installed

the instrument never has to be removed from the panel.

EGT Probe InstallationEGT Probe Installation

EGT Probe Installation

Look at each exhaust stack and determine the best location at which all of the EGT probes can be

mounted at the same distance down from the exhaust ports. The ideal location is 1 1/2", but ease

of installation should prevail. Drill a 13/64" diameter hole in each exhaust stack. Insert the probe

and tighten the hose clamp. As the hose clamp is heated and cooled, it will become loose as it

conforms to the exhaust stack. After the first 10 hours of operation, each hose clamp should be

retightened.

IMPORTANT NOTE: For Cessna 210’s or any aircraft using a slip joint in the exhaust system,

install the EGT probes ABOVE OR BELOW THE SLIP JOINT. Installing a EGT probe in the

slip joint can damage the probe.

5. CHT Probe InstallationCHT Probe Installation

CHT Probe InstallationCHT Probe Installation

CHT Probe Installation

A single CHT probe should be placed on the hottest cylinder. In a 6-cylinder engine this would be

one of the center cylinders. On a 4-cylinder engine this would be one of the back cylinders.

If a second CHT probe is to be installed it should be placed on one of the front unobstructed

cylinders. This will allow the UBG-16 to detect shock-cooling automatically.

Most engines have a port just below the lower spark plug for the CHT probe. If your engine has a

primary CHT probe in one of the cylinders, do not remove it. The UBG-16 is not STC'd as a

primary replacement instrument. Select another cylinder for your probe. If you’re putting a

CHT probe on every cylinder use our P-102 Gasket CHT Probe for your primary cylinder.

TIT Probe Installation

If you currently have a TIT gauge mounted in the aircraft it may be a primary engine instrument.

If this is the case you will need to install a secondary TIT probe. The TIT probe should be in-

stalled on the inlet of the Turbo-charger one to two inches before the Turbo-charger flange. Drill

a 13/64" diameter hole in the exhaust stack. Insert the probe and tighten the hose clamp. As the

hose clamp is heated and cooled, it will become loose as it conforms to the exhaust stack. After the

first 10 hours of operation, each hose clamp should be retightened.

9. OAT Probe InstallationOAT Probe Installation

OAT Probe InstallationOAT Probe Installation

OAT Probe Installation

Mount the OAT Probe in an appropriate location on the aircraft, using the hardware supplied.

The OAT Probe is sensitive to air temperature changes. For this reason, do not mount the OAT

probe in the path of the cowl or engine exiting air (i.e., on the belly of the aircraft). Also, if the

probe is mounted in the cowling area near a turbo or hot cylinder head, radiant heat may influ-

ence the probe temperature. Other than these consideration the OAT Probe may be mounted in

an air intake vent, on the side of the cowling or anywhere else on the aircraft.

NOTE:NOTE:

NOTE: An OAT Probe should be connected to a precision channel on the UBG. That would be

channel 7 or 8 on the left and right Circular Connector. A three to four degree F error can occur

There are two identical pre-wired Extension Cable Harnesses in the installation kit. One end of

each harness has a 16-pin Circular Connector and the other end has red Slip-on connectors on the

individual extension cables (see the Wiring Diagram at the back of this manual). There is a type K

thermocouple extension cable for each EGT and CHT temperature to be measured. The end of

each extension cable in the harness has a piece of yellow heat shrink marked with its channel

number. One of these harnesses is to be connected to the EGT probes (and LEFT connector on the

UBG-16) and the other is to be connected to the CHT probes (and the RIGHT connector on the

UBG-16). Refer to step 4 (Configuration Form) to identify which harness will be used for EGT's

and which will be used for CHT's.

Mark the Circular Connector that will be connected to the EGT probes. The first 4 or 6 channels

(starting with channel #1) are used to monitor EGT's. Any additional channels may be used to

monitor other temperatures or functions. There are 8 channels available on each 16-pin Circular

Connector. Any channel used to measure a temperature other than EGT or CHT (TIT, OAT,

Carb Temp, etc.) will have a type K thermocouple extension cable lose in the kit. Plug any addi-

tional extension cables into the appropriate pins of the Circular Connector (see "Appendix A" at

the back of this manual).

Any channel used to monitor functions other than temperature (RPM, M.P., Oil Pressure, Volts,

Amps, etc.) will require a Functional Module. Installation of a Functional Module will be covered

later in this manual.

Mark each of the Type K thermocouple extension cables in this harness (on the yellow heat shrink)

with the temperature function for which it will be used (i.e., CHT, EGT, Oil, etc.). An ink pen or

marker works well.

If a channel on the UBG-16 is to be used to monitor a function other than temperature, an appro-

priate Functional Module must be installed. A Functional Module is a small box with circuitry

used to convert pressure, RPM, Voltage, Amps, etc. to an appropriate signal the UBG can display.

This signal can be connected to any unused channel on the UBG-16. These modules are small and

System Ground Test

A. Turn the master switch on and look for a near ambient temperature reading on each tempera-

ture channel. If the instrument does not power-up (display a reading), check the power and

ground leads (red and black leads) for an open, loose or poor connection.

If you suspect that any channel is not receiving a signal, remove the probe from the engine

(leaving it connected to the Extension Cable) and apply a temperature to it. Look for an in-

crease in reading on the display for that channel. Check the other channels for an increase in

reading. You may have connected the probe to the wrong Extension Cable. If the reading is

decreasing, you may have reversed the connectors on the Extension Cable leads (the yellow

wire on the probe must connect to the yellow wire on the Extension Cable).

B. Start the engine and check each channel for a proper reading. On the ground (after a few

minutes) EGT’s will read around 900°F and CHT’s will read around 200°F. If you suspect any

channel is not receiving a signal properly, see step A of the “Troubleshooting” section of this

manual.

Because high reliability is designed into Electronics International’s equipment, there is no reason to put

up with poor operation. We have few problems with our probes, cables and units and installation is

simple. Usually fixing a problem is just a matter of inspecting the installation at a few key points.

. Trying to fix all of

them at once can be confusing and misleading. In many cases fixing one problem first will lead you

to the solution for fixing all of the problems. Therefore, take one problem on one channel and

proceed with the following:

A.A.

A. Instrument Check OutInstrument Check Out

Instrument Check OutInstrument Check Out

Instrument Check Out

If there is an identical symptom on each channel, then the instrument may have a problem. But if

even one channel of the instrument is operating properly, the instrument probably does not have a

problem. A good method to test the instrument is to remove all the Extension Cables by discon-

necting the Extension Cable Circular Connector. Then look for a reading on all channels to be

near cabin temperature for temperature channels or zero for channels measuring functions other

than temperature (RPM, Oil Pressure, etc.). The only inputs the UBG requires to operate prop-

erly and measure cabin temperature is power (red lead) and ground (black lead). Check the

power and ground leads for proper connection (pull on the wire at each connector).

Note: Few problems turn out to be the instrument.

B. Probe Check OutProbe Check Out

Probe Check OutProbe Check Out

Probe Check Out

There are two good methods of testing a probe. Perform one or both of the following:

1.1.

1. A probe can be tested with an ohmmeter. Disconnect the probe from the Extension Cable.

When testing the resistance between the connectors, the probe should measure a “short” (less

than 5 ohms). When measuring from one lead (either lead) of the probe to the probe sheath

(metal tip), there should be an “open” (10k or greater).

2.2.

2. Another method of checking a probe is to plug the suspected bad probe into a channel that is

working properly. If the problem follows the probe, you have a defective probe.

C. Extension Cable Check OutExtension Cable Check Out

Extension Cable Check OutExtension Cable Check Out

Extension Cable Check Out

With the Extension Cable connected to the UBG, remove the probe from the suspected bad Exten-

sion Cable. Set the UBG to the proper channel and look for a near cabin temperature reading. A

very high or low reading indicates a short to ground in the cable. Next, connect an ohmmeter, set

to 10K range, to the open probe ends of the suspected bad Extension Cable. Set the UBG to the

proper channel and look for a high (+ or -) reading. A near cabin temperature reading or no

change in reading indicates an open in the cable or its connectors. Most problems of this kind are

usually one of the following:

1. Improper OLC-1 Connections:Improper OLC-1 Connections:
