The design of the automatic firing unit protects it from

damaged by longer blackouts Whenever the supply

startup of the system - even if there has been a power
failure in the meantime. In the event of a malfunction
occurring, the LED indicator in the "Reset" button R
lights up and stays permanently lit until the fault has
been acknowledged (i.e. until the error has been
cleared or the automatic system fault has been dealt
with. The light pauses every ten seconds to emit a
blink-code designed to indicate the cause of the
malfunction.
It is possible, using the readout device (available as an
optional accessory), to obtain further in-depth
information on the system's operating and malfunction
procedures.
Blocking and unblocking the system
The automatic unit can be blocked (corresponding to a
malfunction) and unblocked (cleared) by pressing the
"Reset" button R, provided the system is connected to
the power supply.
If the button is pressed during normal or startup mode,
the device goes into malfunction mode. If the button is
pressed with the system in malfunction mode, the
automatic unit is unblocked.

Always disconnect the power supply before
installing or removing the automatic unit. DO
NOT attempt to open the automatic unit, as
there are no user-serviceable parts inside.
