13.1
Test Set
The TS-31 test set is used to test the operation of the fault pro-
tection functions of the SB Energy-Comm trip unit. It has been
designed to be convenient and easy to use. The user is
prompted on a front panel display, in a step-by-step format,
about the required input information and test instruction. The
test results are displayed on the front panel.
Note: Use individual instructions supplied with the TS-31
Test Set for SB Encased Circuit Breaker testing.
Note: The long time, short time, instantaneous, and ground
fault tests will cause the circuit breaker to trip, thus
interrupting power to protected circuits. Take precau-
tions to prevent damage to equipment protected by
the breker prior to performing the tests.

Operating Instructions
1.
Remove electrical loads from the circuit breaker.
2.
Plug the TS-31 test set into a grounded 120V AC recepta-
cle and turn it on. The following startup message appears:
Siemens Energy & Automation, Inc. TS-31 Test Set.
Press ENTER to continue
3.
Select the appropriate ribbon cable assembly per the
instructions supplied with the TS-31 test set, and connect
it between the TS-31 and the circuit breaker, making sure
of alignment and polarity. Press ENTER, and the TS-31 will
prompt:
Enter Catalog Number
4.
Type in the catalog number and then press ENTER. The
catalog number can be found on the nameplate of the cir-
cuit breaker, or can be viewed via the
System Configura-
tion
menu (see
4.1, Viewing System Configuration
on
page 21). The TS-31 will respond with:
Searching Catalog. . .Searching Family Series. . .
If an invalid catalog number has been entered, the
TS-31 will respond with:
Catalog Number xxxxxx Not Found.
Press Enter to Continue
and you will be asked to enter another catalog number.
5.
If a valid catalog number has been entered, the TS-31 will
prompt for the Breaker switch settings. The TS-31 will
respond with:
Enter continuous current setting in %
Note: Energy Com Trip Units display current in Amps, therefore Amps
must be converted to % Current Setting.
Enter the Rating Plug Value in Amps:
Enter long time delay in seconds.
Enter Short Circuit Protection Setting
1 = Short
2 = Int.
3 = Both:
Note: The Short Circuit Protection Setting can be viewed via the
Short
Circuit Protection
Menu, which is located in the System Configuration
Menu (see
4.2, Setting System Configuration Parameters
on page 21).
Enter short time Pickup.
Select Short Time Delay: 1-Fixed 2-I2t
Enter short time delay in seconds
Enter instantaneous pickup setting.
For breakers with ground fault you will be prompted:
Enter ground fault pickup setting in %
Note: Energy Com Trip Units display current in Amps, therefore % Cur-
rent Setting must be converted to Amps.
Enter ground fault delay in seconds
In each case, enter your breaker’s switch settings. For
example if your breaker is set for a continuous current of
70%, type 70 and then press enter. Entry of erroneous
data in the above steps will result in false tests and results.
6.
Select the test you wish to perform after entering the
breaker switch setting. The TS-31 will prompt:
Enter test to perform; see instructions.
Type in one of the following letters, depending upon the
test you wish to perform:
“L” - Long time or overload test,
“S” - Short time test,
“I” - Instantaneous test.
“G” - Ground fault test,
“C” - Current transformer continuity test,
The TS-31 will report the type of test you selected and give
you a chance to abort the test. For example, if “I” was
pressed above. The TS-31 will display:
Instantaneous Test
