Control unit characteristics
SG 113 - SG 513
GAS control and safety units with non
continuous operation
- SG 113 (one stage),
- SG 513 (two stages),
are appliances of which the programme
is managed by a microcontroller. They
also analyse malfunction, via codified
light signals.
When unit is faulty, the
R
switch light is
on. Every ten seconds, the trouble code
appears until unit is reset.
Thanks to the non-volatile
microcontroller memory, it can be
consulted later.
The unit stops without a signal, if voltage
is below its minimum value, and restarts
automatically, as soon as voltage is
back to normal.
In continual functioning a thermostatic
cut-out is
obligatory
after twenty-four
hours.
Unit removal and installation
operations must be performed with
power off. The unit
must not be
opened or repaired
.
