Power-Up Programming - Electronics International UBG-16 Operating Instructions Manual

Your engine's EGTs will vary at different power, altitude and mixture settings. To further enhance the
UBG's ability to detect a problem, select the EGT Difference ("DIFF") on the UBG's digital display and
note the EGT Difference during climb, cruise and descent. Set the EGT Differential Limit for 30'F higher
than the observed maximum difference. This is only a recommended limit. As you get to know your
engine's normal operating temperatures you may want to adjust this limit accordingly.
When operating in the Normal Mode only and displaying the EGT Difference ("DIFF")
Limit may be set by performing the following steps:
1. 1. 1. 1. 1. Press and hold the mode switch to the left until the word "PROGRAM" appears in the digital display.
Release the Mode Switch. "SET" will appear on the left side of the UBG display. Also, "DIFF" will appear
in the left portion of the digital display and the right portion will
show the current EGT Differential Limit. The digit to the far left
will be blinking.
2. 2. 2. 2. 2. Use the Step Switch to increase or decrease the digit that is
blinking. The EGT Differential Limit can be set from 0 to 499'F
in 1'F increments (although this limit will be converted down to
an even number).
3. 3. 3. 3. 3. Use the Mode Switch to blink a specific digit.
4. 4. 4. 4. 4. To exit this programming mode, push and hold the Mode
Switch to the left until the word "END" appears in the digital display.
Note: Setting a limit to "000" will disable the limit and any alarms. Note: Note:

Power-up Programming configures the UBG for the temperature probes and functional modules connected to its
16 input channels. To understand how to configure the UBG, it is necessary to understand how the input channels
are arranged. On the back of the UBG are three circular connectors. The 16-pin circular connector on the left (as
you face the UBG) is responsible for the left eight input channels on the UBG. This circular connector is used to
monitor EGTs.
The 16-pin circular connector on the right is responsible for the right eight input channels on the UBG. This
circular connector is used to monitor CHTs. Any remaining channels on either or both 16-pin circular connectors
may be used to monitor other temperatures or functions.
The UBG Configuration Form found at the back of this manual and also located in the UBG Installation Instruc-
tions should be used as a guide for Power-up Programming. To configure the UBG, perform the following:
