When making the electrical connections, please always observe
section 3. In standalone systems, earthing of the components is not
necessary, not standard or may be prohibited by local regulations
(e.g. DIN 57100 Part 410 Prohibition of Earthing for Safety Extra-
Low Voltage Electrical Circuits).
4.4.3 Special features, using the button / switch
An external switch can also be used here between the S terminals to
switch the PA15 load output on and off manually. If a switch
(permanent contact) is used for this purpose, the generator can be
switched on and off regardless of the status of the PA15.
Some emergency generating sets which have a start signal input may require a potential-
free switching signal. As the output on the TTS is not potential-free, a relay is required for
the electrical isolation in this case. Even if the starter current on the generator exceeds the
maximum permissible 15A switching capacity of the TTS, a relay or contactor should be
used.
Before connecting the TTS to your generator, ensure that the instructions for
using the generator are observed.
For the Tarom charge controller to be able to record the additional
generator current and to include this in its SOC calculation, an “HS
200” type intelligent shunt should also be used, as described in the
diagram above.
4.4.4 Safety function / behaviour on faulty data transfer
When commissioning the device, the consumer output is always
shut down first (generator off).
Only once a relevant data signal is available to the PA 15 following
a successful data transfer is the load activated.
If the PA15 has shut off the load (generator) due to its controller
position P1 and the data transferred, the load can be reactivated by
reducing the shutdown thresholds.
If the data transfer is interrupted or not activated in the Tarom, the
output remains or becomes shutdown, thus protecting the generator
against overload.
If the data transfer is interrupted, a switch can be used to switch the
output (generator) on or off manually.
The buzzer does not indicate an interruption in the data transfer.
