Settings - load management
General The outputs I/O 0 - I/O 3 can be used to control an actuator (e.g., relay, contactor) via the
load management function.
A connected load can thus be controlled by assigning a power feed-dependent switch-on
or switch-off point.
Load manage-
ment Control
" deactivated ": Control via Energy Management is deactivated.
" by the power generated ": Control via Energy Management takes place through the
power generated
"
by excess power (given feed limits) ": Control via Energy Management is effected by
excess power (given feed limits).
This option can only be selected if a meter has been connected. If the I/Os have a higher
priority than the battery, the possible charging power of the battery is considered to be
surplus. In this case, the switching threshold must not be defined on the gateway.
Thresholds
" on ": For entering an effective power limit at which the I/O output is activated
" off ": For entering an effective power limit at which the I/O output is deactivated.
If " by excess power " is selected under " Control ," additional selection fields for " Feed "
and " Reference " are displayed under "Thresholds."
Runtimes
" Minimum runtime for each switch-on process ": Field for entering a minimum time for
which the I/O output is to be activated for each switch-on process.
"
Maximum runtime per day ": Field for entering a maximum time for which the I/O output
is to be activated in total per day (several switch-on processes are included).
Target runtime
" per day ": Field for entering a minimum time for which the I/O output is to be activated
per day.
"
achieved by ": Field for selecting the time, if the target runtime is to be achieved by a
certain time
Status
If the mouse pointer is moved over the status, the reason for the current status is dis-
played.
IMPORTANT!
If several load outputs are used, they are activated at an interval of one minute depend-
ing on the priority (max. 4 rule = max. 4 minutes).
