Troubleshooting
WARNING
_ab
Risk of electrical shock, risk of damage to equipment.
Electrical installation work must only be executed by qualified personnel that knows and observes the following regulations:
- IEC 364 or CENELEC HD 384 or DIN VDE 0100, respectively,
- IEC-Report 664 or DIN VDE 0110,
- BGV A2 (VBG 4) or equivalent national accident prevention regulation.
CAUTION
_ac
During operation the surface of the vacuum and pressure pump may reach temperatures of more than 70 °C.
Risk of burns!
Let the vacuum and pressure pump cool down prior to a required contact or wear heat protection gloves.
Problem Possible Cause Remedy
The vacuum and pressure pump does not
reach the usual pressure
The drive motor draws a too high current
(compare with initial value after commission-
ing)
Vacuum operation:
Evacuation of the system takes too long
Pressure operation:
Filling the system takes too long
Building up pressure in the system takes too
long
Vacuum operation:
The vacuum system or suction line is not
leak-tight
Pressure operation:
The pressure system or pressure line is not
leak-tight
Check the hose or pipe connections for possi-
ble leak
In case a vacuum relief valve/regulating system
is installed:
The vacuum relief valve/regulating system is
misadjusted or defective
In case a pressure relief valve/regulating system
is installed:
The pressure relief valve/regulating system is
misadjusted or defective
Adjust, repair or replace, respectively
In case a screen is installed in the suction con-
nection/gas inlet (a):
The screen in the suction connection/gas inlet
(a) is partially clogged
Clean the screen
If cleaning is required too frequently install a
filter upstream
In case a filter (62, 63) is installed on the suction
connection/gas inlet (a):
The filter (62, 63) on the suction connec-
tion/gas inlet (a) is partially clogged
Clean or replace the inlet air filter (62, 63), re-
spectively
Partial clogging in the suction, discharge or
pressure line Remove the clogging
Long suction, discharge or pressure line with
too small diameter Use larger diameter
A vane (35) is blocked in the rotor or other-
wise damaged Free the vanes (35) or replace with new ones
(Busch service)
The radial clearance between the rotor and
the cylinder is no longer adequate Readjust the vacuum and pressure pump
(Busch service)
Internal parts are worn or damaged Repair the vacuum and pressure pump (Busch
service)
The gas conveyed by the vacuum and
pressure pump smells displeasing Process components evaporating under vac-
uum Check the process, if applicable
