Safety valve

Warning

Stop the compressor and switch off the voltage. The operator must apply all relevant

Safety precautions

.

 

Never run the compressor without safety valves.

 

No adjustments are allowed.

Testing

The valve can be tested on a separate compressed air line.

Consult your Atlas Copco Customer Centre if the valve does not open at the correct pressure
(see section 

Settings of safety valve

).

7.5

Motor current readout

General

This compressor is equipped with a current meter to measure the main motor current. This
current can be checked on the controller. This current can also be read through a 4-20 mA signal.

Notes

The measuring device is located within the motor's delta configuration. The controller
will calculate and display the corresponding supply current.

Preparation

Two settings determine the displayed current on the controller:

• The dial settings on overload F21: CLASS/I

e

 and %xI

MAX

 .

• A programmed setting in the controller.
