Application
The LA-1.. electronic controllers serve to feed
and distribute the signals of the liquid alarm
sensors LA1S and LA25S.
Description
Two mounting types are available, wall-
mounting LA1.1 and rail-mounting LA1.4.
A line break supervision is integrated for sure
operation.
There are two LEDs for displaying opera-
tional and fault status as well as two potential-
free changeover contacts with «safety-first»
switching action for sure alarm signalling. The
electronic controllers are equipped with an
alarm reset that may be activated or desacti-
vated. During delivery, it is not activated.
By using one of the contacts, a pump or a
solenoid valve in the gas conditioning system
can be switched directly and the second con-
tact can be used as a status alarm.
The switching point of the electronic control-
ler LA-1.. is adjustable via a potentiometer. At
works, a standard alignment is made.
The special electronic controller ER142 Exi
(Part no.: 03E2009/a) without line break super-
vision is for the intrinsically safe feeding of the
LA 1 and LA 25 sensor (old series!) located in
a hazardous area.
