Diagnostic: Status LED's

The CS141 offers several options for diagnosis. The fastest method is a quick visual inspection of the LEDs

To perform a quick inspection, take a look at the two LEDs in front of the CS141:

After logging in, the CS141 will display a more detailed overview of the current system state:

A green marker indicates communication without problems.

Please note the setting no UPS device selected will show a dummy screen and the LED will also be green.

A yellow marker is displayed if:

• The device will initialize and the communication is being established
• there is a warning behavior. It might be required appropriate intervention in the near future.

If the LED is red, an alarm or critical condition is currently detected:

• The CS141 has lost communication with a connected device
• There is a system critical condition, which requires a timely intervention.

The type of the alarm is displayed in detail.

A blue marker indicates that the device was probably configured correctly, but no initial communication has been established.

A gray marker and the description disabled means that a device has been completely deactivated and cannot provide any data.

Example: Quick diagnosis using LEDs and marker

At the front of the CS141 both, red and green LED's, are on, but they should be off or just the green one flashing slowly. The UPS is definitely recognized and seems to work normally.

As you can see the red and the green LEDs are lit statically. Since it is a slot card, it is plugged into the UPS and is supplied with the necessary information about it.

The yellow plug is the ethernet cable to connect the CS141 to the local network.

In this example scenario, the AUX port is the cause of a communication error:

After logging into the CS141, the top status bar displays the following information about enabled devices:

The UPS is set correctly and has made the communication accordingly. The AUX port, on the other hand, is set to initialization. However, since the AUX port has no device connected to the CS141, the yellow marker will change from yellow to blue over time, while the LEDs on the front of the CS141 continue to glow green and red steadily.

Due to the fact that the UPS indicates a green marker and other devices are set to "disabled," the AUX port will cause trouble.

What you can do:

Once a CON_AUX4 or CON_R_AUX4 device has been connected to the AUX port of the CS141 and successfully initialized, the marker in the status bar will turn to green and provide feedback with OK. Furthermore, the LED status at the CS141 will indicate normal operating mode.

If no AUX device is to be used, you can set the AUX port on COM3 to None in the general configuration menu.

In this case, the AUX port will be disabled, and the AUX marker will be removed from the top status bar.

As a consequence, the LED at the CS141 will indicate normal operating mode.
