Page: 39 / 126

Initial Start--- up
7 --- 31
Remove the cover (3).
Note the rotational direction arrow (4).
Grasp the coupling (2) and turn it and the airend shaft (1).
Replace the coupling cover (3).
7.6 Checking Direction of Rotation
The machine is designed for a clockwise field.
Check the supply with a phase sequence indicator.
If the compressor motor turns in the wrong direction, change the motor supply phases
L1 and L2.
Alternatively, the direction of rotation can be checked by briefly switching
the machine on and off again.
Switch the machine off as soon as the direction of rotation is seen
and compare it with the direction arrows on the motor and airend.
7.7 Initial Start ---up
Open the shut ---off valve to the air network.
Switch on at the main supply isolator.
The controller makes a self---test and the green LED ’Power ON’ (16) lights.
Press the ’Operating state LOAD/IDLE’ key.
Press the ’ON’ key (2).
The green LED ’Machine ON’ lights (1).
Allow the machine to idle for at least one minute.
This ensures good distribution of cooling oil.
Press the ’Operating state LOAD/IDLE’ key.
The machine switches to the LOAD state and delivers compressed air.
Watch for any faults occurring in the first hour of operation.
After the first 50 operating hours carry out the following:
Check that all electrical connections are tight.
7.8 Setting Network Pressure
The network pressure (working pressure) is set at the works.
Adjustment is possible to suit individual operating conditions.
Network pressure setting is described in the SIGMA CONTROL service manual.
The machine may toggle a maximum of twice per minute between LOAD
and IDLE.
Reducing starting frequency:
Increase the difference between cut ---in and cut ---out pressure.
Add an air receiver downstream to increase buffer capacity.
