-
The device has been overloaded by excess consumer
current.
Reduce the number of consumer devices connected to the
PA15, max. 15 A is permissible. Insert a new fuse
- Earth fault
Please observe the instructions given in section 7.7, and the
information on earthing in the operating manual for the
TAROM/POWERTAROM charge controller.
- Internal short-circuit in the PA15
Disconnect all the consumer devices, insert a new fuse with
the battery connected correctly. If the fuse blows again, there
is a fault in the device.

No function
Check the connection and the cabling for the Steca PA15.
Check the power supply and the fuse.
Is the PA15 correctly connected to the solar system battery?
If the input voltage in the permissible range of between 10.5V and
60V?
Disconnect all the consumer devices and take out the fuse. Insert
the fuse with the battery connected correctly. If an acoustic signal
can be heard, the basic function of the device is OK. If the fuse
blows, or if there is no acoustic signal despite the correct operating
voltage, there is a fault in the device.
Can the consumer device be switched on and off manually using a
button / switch between the S terminals?
If so, check the configuration for the relevant function. It may be that
there is a problem with the data transfer (see section 7.2.3) or it is
not enabled in the TAROM/POWERTAROM (see section 8.2).
If the consumer cannot be switched on manually, there may be a
fault in the device.
- Load output on the PA15 does not switch ON
Check the basic function of the PA15 according to the instructions
in the “No function” section.
Check the connection to the consumer as well, along with the
correct functioning of the consumer device.
The PA15 does not react immediately to a control signal
transmitted. To increase functional safety, the PA15 must receive
three identical values, otherwise the safety function for the
operating mode selected will be active. Check the behaviour in
accordance with section 8 “Operating modes”. Please note that a
new control signal is only transmitted about once a minute.
