Signal

Notes
Level 2
contact input
(optically
coupled)
(only certain
versions)
Voltage-free contact
or electronic open
collector (NPN) signal;
the terminal also carries
+24Vdc to power the
level sensor, if necessary
The max current
available to power the
sensor is 30mA
The voltage-free contact (or
the open collector) will be
supplied with around 10mA
at 24Vdc
Sensor power supply Imax
=100mA (at 24Vdc)
The presence of this signal can
be either configured or
disregarded
The signal type can be con-
figured (stable level / pulse
or normally open / normally closed)
You can choose the action to be
performed by the controller when
it receives this signal: it can simply
show an alarm on the display or it
can inhibit fluid dispensing if the
"pump cut-out" option is selected
No alarm signal is sent to the alarm
output because the alarm output is
linked to the level 1 contact
24Vdc
auxiliary
power circuits
output
24Vdc auxiliary output
to power remote
displays (if present)
Imax = 200mA limited by
self-resettable fuse
The equipment to be powered must
not draw more than 200mA with
24Vdc power supply Typically this
could be an electronic level sensor
that requires a 24Vdc power input
Alarm output
(optically
coupled)
The alarm output
replicates the status of
level contact number
1 and, in general, the
status of many other
possible fault conditions
Max current rating of the
open collector output:
25mA
The presence of this signal can be
either configured or disregarded
The signal type can be configured as
normally open or normally closed
