Electronic Self-Test
When you switch the pump on with the main On/Off switch the pump
doesn’t start immediately but it starts only after few seconds.
This test time isn’t required if the pump is already powered as when
it is operated in remote or serial mode.
Rotor Lock Test
The rotational frequency is checked continuously. If the rotor
remains still for more than 60 sec. the pump status is changed to
“Fail”.
Oil Level Check
The oil level is continuously checked even when the pump is in Stop
status. If the oil level check highlights at low level while the pump is
OFF, it won’t starts again. If the oil level check highlights at low level
during the pump operation, it will continue to run but, if you switch
the pump off it will be impossible to start again.
