UPS functions

For this configuration step, navigate to the following menu:

The UPS Functions menu includes options to perform test sequences or configure special built-in features that a UPS may offer. These functions are tailored to the specific UPS model in use, reflecting its supported capabilities. Therefore, the options shown in this menu may vary: while some UPS systems only support basic functions such as turning the output on or off and performing a single test, others offer a wider range of advanced features.

The following functions represent typical menu entries:

Custom Test

The Custom Test is an on-battery function test using a self-defined time in minutes.

Battery Test

The battery test checks whether the UPS works properly, and the batteries take over. This test usually takes about 15 seconds. This test will not show how long the batteries will be able to take over.

Full Test

The Full Test will test the batteries until they are depleted. This test can take a long time depending on power and load. The CS141 also accurately measures and determines the runtime under load. Please note UPS systems require a stable load of at least 25% to perform a full test.

Self test

With this test, the UPS checks its own electrical functionality

Note:

In some cases, a UPS command may seem to fail or an error message may appear. This behavior is based on the fact a UPS receives and confirms a command, but without doing it until pre-conditions are fulfilled. As an example, there must be a minimum charge for a particular battery test - otherwise the UPS returns an error message as a result. This result will be logged accordingly as "error". In reverse cases, it is possible the UPS sends a positive feedback despite errors but indicates an error on the front display itself.

Due to these facts in sometimes the behavior of a UPS system is unique and for some cases unfortunately not predictable.

UPS Control settings

Depending on design and model, some UPS systems support additional functions to be used for verifying the performance of the UPS. The scope of functionality and configuration possibilities varies considerably and depends on both the manufacturer as well as the model to be used.

Typical functions a UPS may provide:

Switchable output

Depending on the design, some UPS systems support switchable output ports.

Note:

Depending on the performance class, UPS systems are equipped differently. Due to this fact, the scope of functions varies.
