ERROR SIGNALLING
Signalling through red LED with triangle warning symbol:
1.
fast flashing
=RS485 communication error with control unit.
2.
slow flashing
=error relevant to board PA1013.
3.
steady on =cyclic test in progress.
Should a low battery error occur (control unit error E05), this will not be signalled through the red LED with the
triangle warning symbol, but through the slow flashing of the red LED with the battery symbol.
NOTE During parameter editing from the equipment and/or the PRO keyboard, the danger symbol continues flashing
until "edit parameters" mode is quitted.
