■
Connect screen only to the respective terminals and to the central earthing point (CEP).
■
The rated voltage is indicated on the name plate.
■
When switching off inductive loads, voltage spikes are produced that may impair the op-
eration of control and measuring systems. Connected contactors must therefore be pro-
vided with suppressors such as RC combinations.
■
In the event of an alarm the signal output (terminal 7 and 8) is instantaneously closed.
■
In the event of a malfunction the signal output (terminals 7 and 8) is opened and closed
in a clock-pulse controlled way in order to ensure an optical differentiation between an
alarm and a malfunction signal. If required you can wire terminals 7 and 8 with an exter-
nal signal lamp.
