LED "H" Status Diagnosis

LED "H" provides information about
• whether the latching relay function is enabled,
• where there is a short circuit of the DALI power supply:

Short circuit detection only with WAGO power supply
A short circuit on the DALI line is only detected if the 18 V power is supplied via a
WAGO power supply (item no.: 787-1007 or item no. 753-620).
For this purpose, the "Enable Internal Power Supply" box must be checked (see
section "Module Configuration Notes").
If an external DALI power supply is used, it is not possible to distinguish between
"short circuit" and "voltage not present."

which all display elements of the DALI Multi-Master Module flash green for
approx. 10 sec. This "Wink Function" can be used to identify the affected module
in the node.
