Configure the UBG for Your Aircraft

To configure the UBG to operate with the temperature probes and Functional modules installed in

your aircraft, refer to the Power-up Programming section in the Operating Instructions. Use the

Configuration Form found in this manual as a reference.

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.
