Fault detection and measures

Faults are indicated via the display and via the two relays "K1" and "K2".
The functions of the relays change depending on the programming of the device and the
operating state
•
In standard mode
indication and relay "K2" for fault indication (see Electrical installation/Relay outputs K1, K2 and IO
Setup - Digital outputs DO).
•
After enabling but not activating "Protection Mode" = standby mode, relay "K1" is deactivated (no
function assigned) and relay "K2" is still used for fault indication (function 2K). Inverting of the relays
is possible but other function assignments are blocked.
•
When "Protection Mode" is activated = emergency mode, faults that do not result in the device
being shut down are indicated via relay "K1". Faults that lead to the device being shut down are
indicated via relay "K2". Inverting of the relays is possible but other function assignments are
blocked.
Note: If a redundant system is installed, this indication can be used for switching by the upstream
control.
