Connect the local or remote alarm system to the appropriate
sockets (32, 33 in
Fig. 3 ) using the 3-pole stereo jack provided
(66) (Ø 6.3 mm).
The alarm relay is always energized by default in operating state;
when the alarm is triggered, the relay drops out. This means
that the alarm is triggered even if the ASP6025 is de-energized
(e. g. in the event of a power supply failure).
Connecting the local and remote alarm system
Each alarm is connected to the plug (66) as follows ( Fig. 63 ):
Shared terminal: 2nd neck (69)
Opening contact (inner terminal): 1st neck (67)
Closing contact (outer terminal): Tip (68)
Fig. 62
The alarm systems for the local alarm and the remote alarm are
connected via a 3-pole stereo jack.
The alarm pin of the connector is the center terminal (68) on the
stereo jack. Depending on the configuration of the polarity, the
inner or the outer terminal of the stereo jack is switched through
to the center terminal in order to trigger an alarm.
In addition, the polarity can be configured (reversed) for these
two outputs.
In the Polarity inv. field of the SYSTEM SETUP menu, you can
configure the NC (normally closed) or NO (normally open) key
so that the alarm is forwarded correctly.
(For more information, refer to
Chap. 5.1.2 )
The maximum values of the alarm system connected to the
instrument must not exceed the following:
For 30 V DC, max. 1 A
For 120 V AC, max. 0.25 A
4. Initial Operation
Local alarm: socket (32)
Remote alarm: socket (33)
Connection of an external alarm system (local or remote alarm) is absolutely necessary for preventing damage
to or loss of tissue samples in the event of a malfunction.
