Trotec VE 4 Manuel D'utilisation page 9

• The turbines are special designs with specified
performance curves and only suitable for the
transportation of clean air and clean gases. If
the transportation medium contains solid par-
ticles or other forms of contamination, then a
filter must be installed on the suction side (e.g.
water separator, micro filter).
• The bearings in the turbine are completely en-
cased, maintenance-free, special high tempe-
rature bearings The grease packing lasts a whole
product life-time.
• Maintenance and repair should only be carried
out by the firm TROTEC.
Important information for recycling!
In the European Union electronic equip-
ment must not be treated as domestic
waste, but must be disposed of profes-
sionally in accordance with Directive
2002/96EU of the European Parliament and Coun-
cil of 27 January 2003 concerning old electrical
and electronic equipment. At the end of its life ple-
ase dispose of this appliance in a manner approp-
riate to the relevant legal requirements.
Warning
• Suction side: Compressors in the VE-series
generate a strong suction flow. Small objects and
particles can be sucked in and cause injury. It is
therefore necessary to ensure that no person is
near the suction or discharge inlet when the
compressor is in operation. When there are no
pipes or hoses connected to the suction side, a
protective grille has to be put in place. This grille
is installed as standard when the TROTEC side
channel compressors are delivered. Particular
attention must be paid to ensure that no impu-
rities are sucked into the compressor or enter the
compressor when it is at a standstill.
• Blow-out side: Compressors in the VE-series
generate a strong discharge flow. Objects and
particles that have been sucked in can shoot
out at very high speeds and cause injury. This
is why you should never place your hand in
front of the discharge opening.
• Temperature at the turbine: When in opera-
tion, the temperature of the transport medium
is transferred to the turbine housing and tem-
peratures of over 50°C are reached within a
short time. You should therefore never touch
the turbine housing during operation and allow
it to cool off.

Fault clearance
Not enough or no air at all is being suctioned in
or blown out:
• Check whether the air intake or outlet grilles
are in the compressor ducts are fouled or blocked
(crude particle protection).
The motor isn't turning:
• Check for voltage
• Check the electrical connections and fuses.
• Check motor winding
Service socket inoperative (only VE4):
• Service socket safety fuse blown out due to
overload. Switch off compressor and pull out
mains plug. Unscrew fuse-box cover and re-
place defective fuse. Close cover properly and
switch on unit again.
The motor switches off during operation and
a signal sounds:
The compressor worked outside it's operating
range (Optiflow display red LEDs glowing) and
over temperature protection switched off. This
switch may have one of the following reasons:
• During pressure operation, back-pressure at
the discharge side caused overheating.
• In suction operation drag in the suction line
caused overheating.
Wait until the compressor cooled down, switch
the device on again. Check Optiflow display.
Check the installation and add additional relief
openings, until the display is showing proper
use (green leeds glowing).
• The units are dirty and the inlet grille are
fouled or blocked. Wait until the compressor
cooled down, disconnect the main plug, open
the housing and clean grille and inside of
housing. Re-assemble the housing.

If the motor switched of with out a sound, than

breaker to reset. The circuit breaker is located
at the operating panel ( VE6) or in the unit
(VE4).
Difference between LS switch and Neozed
fuses
Neozed fuses differ from LS switches in
the way they are activated. (Neozed fuse =
thermal activation, LS switch = thermal and
magnetic activation) and their reusability. LS
switches can be switched on again when they
have been activated and are immediately rea-
dy for operation. Unlike Neozed fuses, which
have to be replaced when they have been ac-
tivated because of a current overload or short
circuit.
• LS switches type B provide cable protection
and the current overload, which leads to ins-
tantaneous activation, is 3 to 5 times as high
as the nominal current.
• LS switches type C provide cable protection
and the current overload, which leads to ins-
tantaneous activation, is 5 to 10 times as high
as the nominal current.
