Durch das Umlegen des Kontaktfeldes durch den Thermostaten S wird Kontakt 27 go. öffnet und der Erdschluss vollst1 ndig aus dem System ausgeschaltet. infolgedessen kommt auch

gestellt. Ferner wird an Stelle des ordnungsgemässen Ruhestromes, welcher wie bereits schon erwähnt, über Kontakt 27 fliesst, folgender Ruhestromkreis geschlossen: A, X, 46, D, F, 57, 85, 33, 64, 59, 14, 41, a2, Melder Ii, a3, Ankerstück u3, 18, a4, Melder III, a5, 42, Ankerstück u4, 43, Magnet F, Kontakt 7,4, Magnet B, A.
Die Melder II bzw. III werden bei der Signalgebung in der oben beschriebenen Weise die Signalempfänger D, E zum Ansprechen bringen, nur mit dem Unterschied, dass die Signalströme nicht mehr über Kontakt 27, sondern über Kontakt 33 verlaufen, im übrigen bleibt die Signalgebung die gleiche.
Der in seiner Zuleitung gestörte Melder I wird bei der Signalgebung die Hilfsvorrichtung V, pI, L1 zum Ansprechen bringen.
Im Ruhezustande ist diese Hilfsvorrichtung nicht erregt, indem Ströme von Batterie Z\ obere Wicklung des Magneten V, 66, 31, 25 zur Erdschlussstelle bzw. über die untere Wicklung
EMI3.2
dienen dazu, diese Ströme auszugleichen, so dass der Magnet V für gewöhnlich nicht anspricht.
Erst bei einer Erdung bei T\ d. h. also bei der Signalgebung wird dieses elpktromagnetische Gleichgewicht des Magneten V gestört, so dass infolge der Schwingungen des Ankers v und die hiedurch bewirkten Lokalströme über Lampe pI die Signalgebung erfolgt.

When the thermostat S flips the contact field, contact 27 becomes go. opens and the earth fault is completely switched off from the system. as a result also comes
EMI3.1
posed. Furthermore, instead of the proper closed-circuit current, which, as already mentioned, flows via contact 27, the following closed-circuit circuit is closed: A, X, 46, D, F, 57, 85, 33, 64, 59, 14, 41, a2, detector Ii, a3, anchor piece u3, 18, a4, detector III, a5, 42, anchor piece u4, 43, magnet F, contact 7.4, magnet B, A.
The detectors II and III will cause the signal receivers D, E to respond when signaling in the manner described above, with the only difference that the signal currents no longer run via contact 27 but via contact 33 same.
The detector I, which is disturbed in its supply line, will cause the auxiliary device V, pI, L1 to respond when signaling.
In the idle state, this auxiliary device is not energized, as currents from battery Z \ upper winding of magnet V, 66, 31, 25 to the earth connection point or via the lower winding
EMI3.2
serve to balance these currents so that the magnet V usually does not respond.
Only when grounding at T \ d. H. Thus, during the signaling, this electromagnetic equilibrium of the magnet V is disturbed, so that the signaling takes place as a result of the oscillations of the armature v and the local currents caused by this via lamp pI.
