CLASSIFICATION AND TYPE
According to IEC 60730-1 and EN 60730-1 this unit is a control sensor device, electronic, independent assembly, with ac-
tion type 1B (microdisconnection). Operating value: I <20% I learned. Pollution degree 2 (clean environment) or flow>2,5 l/
min. Rated impulse voltage: cat II / 2500V. Temperatures for ball test: enclousure (75) and PCB (125).
When is detected a dry-run operation the pump is automatically stopped. By mean
of ENTER the normal operation can be manually restored.
After the activation of the dry-running alarm if the Automatic system reset (ART) is
enabled, a first attempt at 5 minutes and then an attempt every 30 minutes for 24
hours is performed in order to restore the normal operation. This alarm can also be
reset manually with the ENTER push-button. If the alarm persists after 24 h we find a
definitive alarm.
When is detected a pressure below a pre-set value and for a pre-set period of time
in the ADVANCED PROGRAMMING MENU, the pump is automatically stopped. The
minimum pressure helps to detect a dry-run operation or pumps running far from its
best efficiency point. This alarm is reset automatically as soon as the pressure exceeds
the limit value.
By mean of ENTER the normal operation can be manually restored.
After the activation of the minimum pressure alarm if the Automatic system reset
(ART) is enabled, a first attempt at 5 minutes and then an attempt every 30 minutes
for 24 hours is performed in order to restore the normal operation. This alarm can
also be reset manually with the ENTER push-button. If the alarm persists after 24 h
we find a definitive alarm.
Overload alarm is activated when the nominal pump current is exceeded. 4 automatic
reset attempts prior to the final alarm are performed.
Normal operation can also be restored manually by pressing ENTER.
