Configuring and Activating "Fallback"
Configure and activate "fallback" in consultation with the network operator
• Only configure and activate the "fallback" in consultation with the responsible network
operator.
1. Log in to the Power Reducer Box as "Installer".
2. Select "Status configuration" in the context menu.
3. In the "Time" field in the "fallback" area, enter the time interval after which the Power Reducer Box
should switch to "fallback" in the event of an invalid input status. Enter a time interval of between
1 hour and 99 hours.
4. Select the "Active" checkbox.
Upper constellation of the status configuration with "fallback" activated
If the connection between the Power Reducer Box and the ripple control receiver is
interrupted, the following input status is present: K1 = 0, K2 = 0, K3 = 0, K4 = 0
This corresponds to the upper constellation of the input statuses on the
"Status configuration" page. If you have activated "fallback" you should not activate the
upper constellation of the input statuses there. The Power Reducer Box will only evaluate
an interrupted connection to the ripple control receiver as invalid and switch to
"feedback" when the upper constellation of the input statuses is not activated.
5. In the "Operating mode" drop-down list select the desired operating mode for the "fallback".
6. Configure the desired operating mode (see chapter 8.3 "Configuring Operating
Modes", page 40).
7. Select [Save].
