PA15 TTS Operating Manual Page 37
A switch between the S terminals can be used to switch the generator on
and off manually, regardless of the control from the PA15.
Solar generator manager (jumper = Solar Manager)
This operating mode is only used for shutting down and activating
additional solar arrays – it is not an expansion of the actual charge
controller.
The operating mode must be set on the jumper block.
An identifier, in other words the “address” for the device, can be set in the
range from 0-8.
This means that up to 8 arrays can be controlled by the charge controller.
For rapid charging of the battery, all the solar arrays connected are
enabled in order to utilise all the solar power available.
When the battery reaches its final charge voltage, the charge power is
reduced by shutting down the solar arrays in stages to prevent the battery
being overloaded.
The additional generators cannot be connected directly to the solar system
via the PA15 output. The coupling needs to be created using a suitable
switching element (relay, contactor), which in turn can be controlled by the
output on the PA15.
In order to prevent reverse current from the battery into the solar
generators at night, all arrays are also shut off.
Safety functions:
If there is an error with the data reception (no data received for 3 mins.),
the solar generators are shut down as the system battery needs to be
protected against overloading.
A plausibility check is used to switch on the generator only once the data
signal has been received 3 times. A one-off data reception alone is
sufficient as a shutdown command.
A switch between the S terminals can be used to switch the generator
connected to the PA15 on and off manually, regardless of the identifier.
Excess manager (jumper = Excess)
This operating mode also needs to be selected on the jumper block.
The excess consumer is activated depending on the current battery
voltage. If the final charge voltage has been reached, the excess
consumer can be enabled by the PA15. The additional consumer device
draws charge power from the battery reducing the voltage on the battery.
If a voltage dependent on the active final charge voltage is not reached,
