NOTE:
When you switch the controller on an electronic
self-test is performed, during such phase you’ll see
the led Orange for 1 sec. And turned off for two
other seconds.
Immediately after the first phase the controller per-
form a specific test on the pump rotor in order to
be sure that it isn’t locked.
Electronic self-test
When you switch the pump on with the main
On/Off switch the pump doesn’t start immediately
but it start only after about three 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
After the electronic self-test the inverter perform a
rotor lock test. This test requires about 5 seconds.
During this time the rotor turns very slowly; after-
wards the pump accelerate. The acceleration time
is a function of the oil temperature and of the
chamber volume to rough down. The lower is the
oil temperature the longer is the time required to
reach nominal speed.
Oil level check
An oil level check is performed four minutes after
the pump starting.
If the pump oil level is under the minimum thresh-
old the pump controller generate a message you
are able to receive by status led blinking (see the
Status Led table), RS232 window (see Windows
Meaning table) and a signal on I/O port (see I/O
table).
NOTE
If the oil level check fails (low level) the pump
doesn't stop. The test only activates the output de-
scribed above.
An Oil level sensor fail is highlighted by means of
quick status led blinking and RS232 window (see
"Status led" and "Window meaning" tables).
IP44 ACCESSORY KIT P/N 949-9367
Using the IP44 accessory kit you can make the
pump protected against solid and liquids as de-
fined here below:

der power or internal moving parts with tools,
wires, or similar objects with a size larger than
1mm.
•
Protected against intrusion of parts larger than
1mm.
Protection against liquids
Water spray from all directions has no negative ef-
fect on the device.
