4. Initial Operation
Remote alarm
This alarm is also external to the Leica ASP300 S.
If installed, it might typically be connected to a
remote dialer that sends an automated phone
message to the person responsible for after-
hours problems.
The remote alarm is only generated when the
instrument cannot continue with an infiltration
program.
4.6 Alarm functions
The Leica ASP300 S is equipped with 3 different
alarm functions:
Instrument alarm
This instrument alarm is generated from within
the instrument itself for all alarm messages.
Local alarm
This alarm is external to the Leica ASP300 S, e.g.
in the office of the instrument operator.
The local alarm is used when the instrument
cannot continue with the current program or
operation because of a problem.
Each alarm is connected to the plug (34) as
follows (see Fig. 12 ):
Shared terminal: Tip (36)

Normally Open Contact:

Connect the alarm system (optional)
If required, connect the local or remote alarm
system to the appropriate sockets (34) (Ø 6.3 mm)
using the stereo jack provided (9, 10 in Fig. 8 ).
Local alarm: socket (9)
Remote alarm: socket (10)
Note that if installed, the remote alarm
will still operate even if the local
alarm is not installed.
Both, local and remote alarm options,
are relays that are voltage-isolated
from the rest of the instrument. When
an error condition occurs, the relevant
alarm circuit closes.
The remote alarm device connected
to the instrument must be rated at less
than 2 amp.
A maximum voltage of 30 V DC may be
present.
