Setting up the instrument
Each alarm is connected to plug (
34
) as follows
(see
Fig. 9
):
Common terminal:
tip (
36
)
connection inside
Normally Open
Contact:
First sleeve (
35
)
connection outside
Normally Closed
Contact:
Second sleeve (
33
)
Threaded connection
Both, local and remote alarm op-
tions, are relays that are voltage-
isolated from the rest of the instru-
ment. 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.
Alarm connections
(optional)
If required, connect the local and/or remote
alarm systems to the alarm sockets (
9, 10
in
Fig.
8
)
at the instrument console, using the phono
jack (
34
) supplied (Ø 6.3 mm).
Local alarm:
socket (
9
)
Remote alarm: socket (
10
)
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 in-
strument cannot continue with a Processing pro-
gram.
Note that if installed, the remote
alarm will still operate even if the
local alarm is not installed.
4.5 Alarm functions
The Leica ASP300 S is equipped with 3 different
alarm functions:
Instrument alarm
This alarm is generated from within the
Leica ASP300. The Instrument alarm is used 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 op-
eration because of a problem.
