Function
Pump Temperature
sensor
Allows regulation of pump temperature.
Indicates a pump temperature variation (a war-
ning when temperature is greater than the warning
threshold and an hazard when temperature is
greater than alarm threshold).
Motor power sensor
(included in the
frequency converter)
Monitors the power consumed by the machine
by generating an hazard as soon as the power
exceeds a preset program threshold for a preset
duration time. The pump is stopped immediately
when the hazard occurs.
Warning water fl ow
switch *
Indicates a water fl ow below 60 l/h.
Warning motor
temperature switch *
A motor temperature warning is generated when
the warning threshold is exceeded.
Hazard motor
temperature switch *
The pump is stopped immediately when the hazard
threshold is exceeded.
Pressure sensor *
Indicates exhaust overpressure when the pressure
reaches 1600 hPa (silencer clogged) and stops the
pump at 2000 hPa.
Flow sensor
Monitors the N
2
injection into the pump. When
fl ow is under the preset threshold, a N
2
warning
is generated.
* These thresholds are factory set and can not be customized.
