4.3.3 Example
Let’s say you want to connect a television set to the standalone
network via this decentralised exhaustive discharge protection. It
should only be possible to operate the device if the load status for
the solar battery is at least 50%. Therefore, set the range “<50%”
(=4) on P1. So that the television set is not switched on and off
continually when the SOC fluctuates slightly, a value at least 10%
higher than the shutdown threshold should be set for the
reactivation threshold (P2). In other words, set “P2” to >=70% (=7)
for example. So that the remote switch “knows” that it should act as
an exhaustive discharge protection device, also set the jumper to
the “SOC MANAGER” position, and if you want an acoustic early
warning to be emitted, set the second jumper to the “BUZZER”
position.
4.3.4 Special features, using the button / switch
If required, an external button can be connected between the two
terminals marked with an S. Assuming the shutdown threshold on
P1 has not yet been reached, this button can be used to switch the
load break switch on the PA15 on and off manually just like a
remote-control switch. Multiple buttons can also be connected in
parallel in order to install multiple light switches in a room, for
example. This button can also be installed at a later stage once the
device is already in operation.
4.3.5 Safety function / behaviour on faulty data transfer
When the device is commissioned, the consumer output will always
be enabled if the SOC is above the shutdown value (P1). In this
case, it doesn’t matter if the SOC is also higher than the hysteresis
value (P2).
If the shutdown value (P1) has not been reached, however, the
hysteresis value (P2) must be exceeded once again in order for the
load to be switched on.
If the PA15 has shut off the load due to its controller position and
the data transferred, the load CANNOT be reactivated by reducing
the shutdown thresholds. The activation value needs to be reached
first. Reactivation can only be achieved by reducing the activation
value accordingly. In this case, ensure that the shutdown value P1
is always smaller than the activation value P2; if necessary, reduce
the shutdown value in parallel with the activation value P2.
