under CV conditions the transistor T7 in the ! TO R-gate" is conducting. The
collector current of T7 is amplified in the amplifier Tll
+
T20 0 , giving
a positive voltage to the bas e of T 2 0 1 .
Th en
the
Schmitt-trigger switches to the state where the C V lamp i s lit.
Cnder
CC conditions T7 is not conducting, T2 0 1 is switched off and T2 02
on through the amplifier. The CC lamp is then lit .
As
a
remote indication option the relay Kl can b e ins erted. It is connected
in
parall el with the C C lamp and thus pull s under CC conditions . This clos es
'.he circuit
via the rear output prongs A and I.
This
can be used for
a
remote b ell or lamp etc .
