separator and no gaseous matter generates.
The vacuum pump does not start
The drive motor (400) is not supplied with the
correct voltage or is overloaded
Supply the drive motor (400) with the correct voltage
The drive motor starter overload protection is too
small or trip level is too low
Compare the trip level of the drive motor starter overload
protection with the data on the nameplate
Correct if necessary
In case of high ambient temperature:
Set the trip level of the drive motor starter overload
protection 5 percent above the nominal drive motor
current
One of the fuses has blown Check the fuses
Version with AC drive motor: capacitor damaged Repair motor (Greenco service)
The connection cable is too small or too long
causing a voltage drop at the vacuum pump
Use sufficiently dimensioned cable
The vacuum pump or the drive motor is blocked
Make sure the drive motor is disconnected from the
power supply
Remove the fan cover
Try to turn the fan by hand
If the unit vacuum pump/drive motor is still frozen,remove
the drive motor and check the drive motor and the
vacuum pump separately
If the vacuum pump is blocked:
Repair the vacuum pump (Greenco service)
The drive motor (400) is defective Replace the drive motor (Greenco service)
The vacuum pump is blocked
Solid foreign matter has entered the vacuum pump
Repair the vacuum pump (Greenco service)
Make sure the suction line is equipped with a mesh
screen
If necessary additionally provide a filter
Corrosion in the vacuum pump from remaining
condensate
Repair the vacuum pump (Greenco service)
Check the process
Observe the chapter “Installation and Commissioning,
Operating Notes, Conveying Condensable vapors” in
page 8
The vacuum pump runs in the wrong direction in the
case that it is equipped withi three-phase motor
Repair the vacuum pump (Greenco service)
When connecting the vacuum pump make sure the
vacuum pump will run in the correct direction (see
“Installation” in page 6)
After shutting down the vacuum pump the vacuum
system exerted under pressure onto the pump
chamber which sucked back excessive oil from the
oil separator into the pump chamber
When the vacuum pump was restarted too much oil
was enclosed between the vanes (22) Oil could not
be compressed and thus broke a vane (22)
Repair the vacuum pump (Greenco service)
Make sure the vacuum system will not exert
underpressure onto the shut-down vacuum pump, if
necessary provide an additional shut-off valve or
non-return valve
Condensate ran into the pump chamber
When the vacuum pump was restarted too much
condensate was enclosed between the vanes (22)
Condensate could not be compressed and thus
broke a vane (22)
Repair the vacuum pump (Greenco service)
Make sure no condensate will enter the vacuum pump, if
necessary provide a drip leg and a drain cock
Drain condensate regularly
The vacuum pump starts, but labours or
runs noisily or rattles
The drive motor draws a too high current
(compare with initial value after
commissioning)
Connection(s) in the drive motor terminal box are
defective
Not all drive motor coils are properly connected
The drive motor operates on two phases only
Check the proper connection of the wires against the
connection diagram
Tighten or replace loose connections
The vacuum pump runs in the wrong direction Verification and rectification see “Installation and
