PA15 TTS Operating Manual Page 36
Safety function:
Without any data received, the consumer should remain switched on. If
the PA15 is connected directly to the battery, the battery can be
discharged completely.
As an option, the PA15 can also be connected to the load output for the
TAROM charge controller. In this case, the last instance of the charge
controller (Tarom) exhaustive discharge protection will be the central
exhaustive discharge protection.
The transmission safety is also supported by a plausibility check for the
data transferred.
By connecting an external button, the consumer can always be switched
on and off manually within the operating range set.
Outside this range, the consumer can only be switched on by pressing the
button continuously or using a switch.
For DC generators
In principle, the operating mode here is the same as for the consumer.
The activation and shutdown threshold can also be set here.
The jumper setting must not be changed for this operating mode. The only
point to ensure here is that the switching threshold is set using P1.
In this operating mode, the value for P1 must always be greater than the
value for P2.
For example, the generator is switched on via the load break switch at an
SOC of <50% and switched off again at >=50%.
This configuration can be used to control a back-up diesel generator, for
example, which is started if the SOC of 50% is not reached.
It is essential that the generator being used cannot exceed the permissible
final charge voltage for the battery.
To determine the optimum SOC using the Tarom system manager, an
“intelligent shunt” is also required in this case, which allows the charge
controller to record this additional charge current.
This shunt is available as an accessory for the Tarom system.
Safety functions:
It there is no data received, the generators connected will be off as the
system battery needs to be protected against overloading.
In this operating condition, as well, data security is improved using a
plausibility check.
