Problem Cause and corrective measure

The login page does not open. The ClusterController is not connected to the voltage sup-

ply.

Corrective measures:

• Ensure that the three-pole plug for the voltage supply

is connected to terminal X1 of the ClusterController.

The voltage supply is reverse-connected or the power sup-

ply unit is defective.

Corrective measures:

• Ensure that the voltage supply is correctly connected

(see the ClusterController installation manual).

• If the voltage supply is connected correctly, replace

the power supply unit.

A firewall is blocking the connection.

Corrective measures:

• Adjust the firewall settings in order to allow the

required connection.

If the ClusterController is connected to the LAN via DHCP

and the voltage supply of the ClusterController was

briefly interrupted, it is possible that the DHCP server has

assigned the ClusterController a new IP address.

Corrective measures:

• Select the display view External communication

and read out the current IP address of the

ClusterController.

• Call up the IP address via the web browser.
