After energizing the easYgen, a delay is started, which
allows a possible "Missing members" alarm to become
active. This delay depends on the Node-ID of the
easYgen (parameter 8950 Ä p.
rate of a load share fast message (param‐
eter 9921 Ä p. 322) and may last for approx. 140 sec‐
onds for a high Node-ID (e.g. 127). This delay serves
for detecting the Master of a CAN bus connection.
Approximately two minutes after energizing the
easYgen, the alarm delay will be set to a fix time,
which depends on the setting of param‐
eter 9921 Ä p. 322 (Transfer rate LS fast message)
and is in the range between 3 to 12 seconds.
