ELECTRICAL SYSTEM
DESCRIPTION
This section describes the standard electrical system.
For schematic diagram, see annex.
The electrical equipment of the compressor unit consists of:
-
drive motor
- electric control system
To start the electric motor and enable the functioning of the
electric control, the following components are essential:
-
main switch and main fuse, both to be installed by the
customer.
DRIVE MOTOR
The compressor unit is driven by an alternating or a three
phase current motor by means of a V-belt.
MOTOR PROTECTION SWITCH (ALTERNATING CUR­
RENT MOTOR)
Protection of the motor is ensured by the thermic releases
integrated into the motor protection switch (2, Fig. 34). The
response value is preset.The motor is switched on manually
by pressing the 0-I switch to I. For safety of the operating
personnel all voltage carrying parts have a protective cover.
MOTOR PROTECTION SWITCH (THREE-PHASE
MOTOR)
The motor is switched on manually by turning the switch to
1 (1, Fig. 34). It is switched off manually by turning the
switch to 0.
For safety of the operating personnel all voltage carrying
parts have a protective cover.
After the switch has shut off by overcur­
rent triggering, the motor can be re­
started by pressing the start-button not
before the bi-metal in the switch has cooled down.
This may last a couple of minutes.
Protection of the motor is ensured by the thermomagnetic
releases integrated into the motor protection switch. The
response value of the electromagnetic releases (protection
against short-circuit) is preset.
MAINTENANCE
For the electrical system no regular maintenance is re­
quired.
Refer to chapter 3. for proper installation and cooling air
supply. For maximum ambient temperature, see Technical
Data, chapter 1.

COOLING SYSTEM
The cylinders of the compressor block, the intermediate
coolers and the after-cooler are air-cooled.
For this purpose, the compressor is equipped with a fan­
wheel connected to the counter-weight at the crankshaft
end opposite to the V-belt pulley. It draws the cooling air
through the fanwheel cover from the surroundings.
