Table 10-11 Scenario 10: SCK-M-I-8S-20A / SCK-M-U-1500V

Device/error description Status register LED indicator

SCK-M-I-8S-20A (2903241) /

SCK-M-U-1500V (2903591)

Data from the connected SCK-M-U-1500V

voltage measuring module is incorrect.

No entry POWER LED:

ON

Cause

The value is outside the valid voltage range of the module.

Measures

1. Make sure that the value is not outside the valid voltage range of the device (see Sec-

tion “Voltage measurement” on page 25) .

Table 10-12 Scenario 11: SCK-M-I-8S-20A / other analog device

Device/error description Status register LED indicator

SCK-M-I-8S-20A (2903241) / other analog device

Data from the connected analog device is

incorrect.

No entry POWER LED:

ON

Cause

The analog device is not electrically isolated from the power supply of the SOLARCHECK

communication module. This affects the voltage value at the analog input of the SCK-M-

I-8S-20A.

Measures

1. Make sure that the supply for the analog device and the SOLARCHECK communica-

tion module are electrically isolated. Use a separate power supply for the analog de-

vice, for example.

Table 10-13 Scenario 12: SCK-M-U-1500V

Device/error description Status register LED indicator

SCK-M-U-1500V (2903591)

The voltage at the analog input of the SCK-M-I-

8S-20A or the controller is between 0 V … 2 V.

No entry POWER LED:

ON

Cause

A cable break has occurred or there is a faulty connection between the SCK-M-U-1500V and

the SCK-M-I-8S-20A or controller. This error can be detected with the “live zero” signal.

Measures

1. Check the connection between the devices and remove the error.
