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
If entered, the CS141 automatically indicates regular operating period for the installed batteries will expire. By default, the
CS141 logs in with appropriate system notes after 48 months. Editing this value will extend or shorten the default time period
until the CS141 will start sending maintenance notifications.
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 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%.
