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 conguration 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 congured (reversed) for these
two outputs.
In the Polarity inv. eld of the SYSTEM SETUP menu, you can
congure 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
