Configuration of a UPS

For this configuration step, navigate to the following menus:

Navigate to the UPS submenu, then click on Setup to enter the basic UPS configuration menu. This configuration dialog allows to choose the UPS your CS141 is installed to – recommended values will be entered automatically by selecting a UPS:

In some cases, the UPS protocol does not provide the appropriate data.  The CS141 will, based on the data situation, independently calculate the corresponding battery life runtime. In general, these settings do not need to be changed if you can select a UPS model directly from the list - optimized configuration settings will be displayed after selecting the UPS.

If your UPS operates with a system configuration that differs to the basic model, it is possible that you need to adjust these default values: In this case, please refer to your local UPS dealer or the UPS manufacturer of the UPS to get the correct values.

Entering wrong values may cause heavy system failures

Note:

By default, OEM ID 12 / GENEREX SYSTEMS is set. If you want to use a UPS from a manufacturer that is not listed, take a look at the download area of ​​www.generex.de - Search for the firmware for your UPS and install it as a regular firmware update.

Afterwards the corresponding UPS models are available.

Adjustable information about the installed UPS

Model

Defines listed default setting of a UPS including the corresponding communication protocol. When your UPS is listed and communication has been established, telemetry of the UPS typically provides all the necessary data that the CS141 needs to calculate and display autonomy times.

Please note that changing the UPS model will also reset the configuration of the UPS events. The CS141 therefore offers the possibility to create a corresponding backup of the event configuration beforehand:

Cancel:                      Do not make any changes to the system

Do not save:             Continue without backup

Save:                         Create a Backup of the event handling

Power (VA)

Defines the maximum power in VA the selected UPS in can provide. Exceeding the maximum may cause the UPS getting damaged or even destroyed

Load (VA)

This value defines the maximum load connected to the UPS. Even if the possibility is given, exceeding the power VA value can damage or destroy the UPS as well as the installed batteries.

The maximum possible value is less or equal to the value entered at Power (VA).

Hold Time (min)

If main power fails, the batteries of a UPS will ensure this operating time if 100% load is used. The real-life uptime is determined dynamically by the percent of usage: of you use 50% the hold time will raise accordingly.

Recharge Time

Estimated time window for a complete charge cycle..

Note:

Behind the values ​​of power (VA), load (VA), holding time and battery charging time, a mathematical formula is stored - this will allow the CS141 to calculate independently battery operating time and trigger corresponding system events. Thus, allow to use the CS141 even if the UPS protocol cannot provide real-time data ​​- as an example, if a UPS only communicates via switchable contacts or only basic operating states can be detected.

Baud Rate

Different protocols provide different speeds of data transmission. The baud rate defines the speed at which data can be sent and received. An incorrect baud rate can cause communication problems between the CS141 and the UPS.

Cable Type

UPS manufacturers sometimes use specially designed cables for their models. In addition to these in-house developments, there are standardized cable types. These cable types can be used to map different functions and switching states.

UPS-ID

If large UPS systems use more than one UPS module, these modules can be queried directly via a unique ID. „0“is hereby a something like a broadcast to allow the CS141 search and manage capability to figure out the number of UPS modules. If you change this value, you only get the exact module with this special ID. Otherwise the CS141 will manage all available modules and display them at the monitoring screen.

Battery installation date

The lifespan of batteries running inside a UPS is limited - regular battery maintenance also requires replacement. In order to keep track of larger installations, you may enter the date when the batteries start into operation.

Battery too old after

The CS141 automatically generates maintenance notifications when the service life of installed batteries expires. This time window in months is internal calculated with an avarage value of 30 days / month timer, regardless of additional date/time settings. Default time windows is 48 months. If necessary, adjust to the respective recommended maintenance period.

System shutdown time

In principle, the system shutdown time is the last emergency shutdown event that will be executed just before the UPS itself will shut down itself to prevent battery damage. This value can be used to trigger the according system event. Please note that this value is an emergency shutdown – it is not suitable to ensure a regular system shutdown.

Apply / Cancel

Apply allows you to save and restart the UPS service on the CS141. Cancel will abort the configuration process and withdraw all settings – they need to be entered again.

Battery Health Level feature

The battery health level will be automatically provided by CS141 inside the UPS configuration menu if the UPS connected to the CS141 principally carries out battery testing but does not return a reporting value for "Battery test passed / faulty". Thus, the result needs to be determined by comparing two measurements:

Before the battery test starts, the battery voltage will be recorded. This value will be compared with the battery voltage to be found after finishing the battery test. The Battery Health Level (%) setting defines the maximum percentage deviation these two values ​​may differ. On exceeding this value, a battery failure will be displayed.

The default setting for this test is 10% deviation - but can be specified with a custom value between 5% and 30%.

Feature: The RFC1628 UPS interface

In some cases, UPS manufacturers supply systems that the CS141 cannot communicate to. As an example, known problems are the card does not fit to the slot, or that the data stream sent by the UPS is not compatible formatted:

UPS manufacturers have installed their own SNMP card, which offers similar functions but may not be compatible to your flexible and powerful GENEREX software environment. To ensure compatibility, the CS141 Web Manager offers the option to connect to any card via SNMP. The condition is that the RFC 1628 MIB is supported by the target card. In order to use this function, it is first necessary to configure a corresponding SNMP Agent at the target UPS.

After that enter the access data in the CS141 UPS menu. The CS141 will restart required services an establish a connection to the destination card.

Setting up the target SNMP card with SNMP v2

Model

Choose SNMP UPS-RFC 128 compliant as UPS model

SNMP-Version

Depending on the configuration of your target SNMP card, choose SNMP version 1 or 2

SNMP Community

Enter the SNMP Community configured at target SNMP card

Save/Abort

Abort will withdraw all settings, save will restart required services. After restarting the services CS141 will automatically establish a communication to target SNMP card.

Note:

What is the difference between the RF1628 UPS interface and the APC Smart Network?

In principle, the APC card can handle the RFC1628 standard - you will be able to query basic information about the UPS. However, the APC cards often uses their own OIDs. These OIDs are specific to AP and not conform to the RFC1628 standards.

Therefore, it is recommended to use the APC Smart network setting instead of RFC1628 interface.

Setting up the destination card using SNMP v3 at CS141

The CS141 supports SNMP v1, v2, and v3 in this mode.

Enter the access data for the destination card according to your configuration and click Apply
