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 .
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:
• 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:
The compressor worked outside it’s operating
range
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 motor has cooled off; switch
the unit on again and monitor the ampere meter .
Check the installation and make release holes
to improve air circulation to allow the com-
pressor to operate in the intended operating
range .
• 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 .
