10.2.2 Confirming Errors on the SC-COM Interface
The installer password is required to confirm an error on the SC-COM interface. The SC-COM
technical description contains a detailed description of the SC-COM interface.
1. If there is an insulation error, switch the insulation monitoring device back on.
2. Select the parameter "Ackn" and set it to "Ackn" (see section 5.2 "Changing
Parameters", page 34).
3. Confirm entry with [Save].
10.3 Displaying the Error Delay Time
Certain errors such as grid faults will cause the Sunny Central to shut down. If this happens, there is
a delay time before the Sunny Central can restart. This is referred to as the delay time of the error
(TmsRmg).
If the Sunny Central has a display, it will show the delay time when reading out the error.
1. Select the Spot Values tab on the SC-COM interface (see section 5.1 "Displaying Spot
Values", page 34).
2. View the delay time via the "TmsRmg" channel.
Handling errors
Errors should only be confirmed when they have been corrected.
