Purge sensor
Signals insufficient gas purge during an
alert time, and stops pumping at the end
of the alarm time.
Signals exhaust overpressure when the
pressure reaches 1450 mbar (silencer
clogged) and stops the pump at
1990 mbar.
Gas
Signals a gas temperature variation at
Temperature
the exhaust with :
sensor
- an alert 1 when the temperature is less
(Non TC version)
than the alert 1 threshold
- an alert 2 when the temperature is
greater than the alert 2 threshold without
stopping the group.
Pump Temperature
Allows to regulate ADP temperature.
sensor on
Signals a pump temperature variation
TC version
(an alert when temperature is less than
the alert threshold and an alarm when
temperature is greater than alarm
threshold).
Motor
Monitors the power consumed by the
power sensor
machine by generating an alert followed
by an alarm as soon as the power is
greater than each of its thresholds;
the pump is stopped immediately when
the alarm threshold is exceeded.
E Analogic sensor
Allows to monitor a voltage on an input
contact with 2 adjustable thresholds.
E1 and E2 logic
Allows to monitor a logic sensor during
sensors
an alert time and stop pumping at the
end of the alarm time.
