3.2 Starting (Fig. 3.4)
Attention
The operator must apply all relevant safety precautions, including those mentioned in this instruction
book.
1.
On compressors with an IMD dryer,
close drain valve (8-Fig. 1.5).
2.
Check the oil level, which must be in the middle of sight-glass (SG-Fig. 3.3). Top up, if
necessary, with the correct type of oil.
3.
On ZR
, check the setting of the valves (1 and 4-Fig. 3.6 or 5, 6 and 7-Fig. 3.7 in case of IMD
dryer) as described in section 3.1. This can be overlooked if, after previous operation, the
settings of these valves have not been disturbed.
4.
Close the manual condensate drain (1-Fig. 3.5).
5.
Open the air outlet valve (customer's installation).
6.
Switch on the voltage and check that voltage on LED (6) lights up.
7.
Press start button (1). The compressor starts running and automatic operation LED (8) lights
up.
8.
On compressors with an IMD dryer,
open the air outlet valve of the dryer (10-Fig. 1.5) and
close by-pass valve (9-Fig. 1.5).
9.
On 10 bar compressors,
check that the temperature difference between the outlet of both
elements is not more than 5°C. If it exceeds the 5°C, check that the difference between the
highest element temperature and the surrounding temperature does not exceed 185°C. If the
value should be exceeded, contact Atlas Copco.
Warning
-
When the compressor is stopped and automatic operation LED (8) is alight, the compressor
may start automatically.
-
If the start/stop timer is active, the compressor may start automatically, even if it was stopped
manually. Consult the User manual for Elektronikon regulator, section “Programming Clock
function”.
3.3 During operation (Fig. 3.4)
When automatic operation LED (8) is alight, the Elektronikon regulator is automatically controlling the
compressor: the air delivery is matched to the air consumption, the compressor will start and stop
whenever necessary.
Keep all doors closed during operation.
3.3.1 Checking the display (2-Fig. 3.4)
1.
Daily check the display for readings and messages. Normally, the main screen (Fig. 1.11) is
shown, indicating the compressor outlet pressure, the status of the compressor and the
functions of the keys below the display.
2.
Always check the display and remedy the trouble if alarm LED (7) is alight or blinks. Consult
section 1.8.
3.
The display will show a service message if a service plan interval has been exceeded or if a
service level for a monitored component has been exceeded. Carry out the service actions of
the indicated plans or replace the component and reset the relevant timer. Consult your Atlas
Copco Customer Centre. See also section 4.1.
4.
Regularly check the actual compressor status by pressing the
↓
key from the main screen.
Warning
Before starting any maintenance or repairs:
-
Stop the compressor and close the air outlet valve.
-
Press the test buttons (Fig. 1.8) on top of the electronic water drains to depressurize the air
system and open the drain valve (1-Fig. 3.5). If an IMD dryer is installed, open drain valve (8-
Fig. 1.5).
-
Open the isolating switch (customer's installation) to switch off the voltage to the compressor.
Apply all relevant safety precautions, including those mentioned in this book.
