From the electrical and electronic standpoint
MC BOX 1.5 ETL
offers standard operating
conditions and preset operating limits
Motor driving

Electronic
key input
Yellow key (user key):
PIUSI electronic key
enabling input
A software procedure is
used to record the yellow
user keys on the PC and
they are then enabled
for use at one or more
dispensing stations
The presence of the keys can be
either configured or disregarded
Gray key (manager key):
PIUSI electronic key
enabling input
Used to configure the panel
and download dispensing
data in relation to
SSM1.5
The presence of the keys can be
either configured or disregarded
Nozzle
contact input
(optically
coupled)
(only certain
versions)
Voltage-free contact
or open collector
electronic signal (NPN)
The voltage-free contact (or
the open collector) will be
supplied with around 12mA
at 24Vdc
The presence of this enabling signal
can be configured or disregarded
The signal type can be configured
(stable level / pulse or normally
open / normally closed)
Pulser
IN input
(optically
coupled)
Voltage-free contact
or open collector
electronic signal
The voltage-free contact (or
the open collector) will be
supplied with around 1mA
at 24Vdc
The maximum input signal
frequency is 300Hz with minimum
half-period (Hi or LOW) of 03ms
Level 1
contact input
(optically
coupled)
(only certain
versions)
Voltage-free contact or
open collector (NPN)
electronic signal; the
terminal also carries
+24Vdc to power a level
sensor, if necessary; the
max current available
to power the sensor is
30mA
The voltage-free contact (or
open collector) will carry
around 12mA at 24Vdc Imax
for sensor power= 100mA
(at 24Vdc)
The presence of this signal can be
either configured or disregarded
The signal type can be configured
(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 and
activate the OUT alarm output or
it can inhibit fluid dispensing if the
"pump cut-out" option is selected
