User manual
1 General description
The electronic regulator automatically controls the compressor, i.e.:
- matching the compressor output to the air consumption
- stopping the compressor whenever necessary
- restarting the compressor when required
In order to control the compressor and to read and modify programmable parameters, the regulator
has a control panel provided with:
- LEDs indicating the status of the compressor
- a display indicating the operating conditions, a service need or a fault
- keys to control the compressor and to have access to the data collected by the regulator
- buttons to manually start and stop the compressor
- an emergency stop button or isolator switch
In general, the regulator has following functions:
- controlling the compressor
- protecting the compressor
- monitoring components subject to service
- automatic restart after voltage failure (made inactive)
1.1 Controlling the compressor
The regulator matches the air output to the air consumption by speed regulation of the motor.
The regulator takes into account a number of programmable settings, such as:
- net pressure setpoint
- indirect stop offset
- direct stop offset
- proportional band
- integration time
- minimum speed
- minimum stop time
- maximum speed limit
- power recovery time (if automatic restart after voltage failure is activated)
If the net pressure keeps on rising when the compressor runs at minimum speed, the regulator will
stop the compressor. The regulator restarts the motor as soon as the net pressure approaches the
net pressure setpoint.
The regulator stops the compressor whenever necessary:
- Indirect stop: i.e. the compressor runs at minimum speed and the net pressure rises to the
indirect stop level.
- Direct stop: i.e. the compressor runs at a speed in between minimum and maximum and the
net pressure rises above the direct stop setpoint.
Both settings are programmable; see section 18.

User manual
1.2 Protecting the compressor
1.2.1 Shut-down and fan motor overload
If the compressor element outlet temperature exceeds the programmed shut-down level, the
compressor will be stopped. This will be indicated on the control display.
The compressor will also be stopped in case of overload of the fan motor.
1.2.2 Shut-down warning
If the compressor element outlet temperature exceeds a programmed value just below the shut-down
level, this will also be indicated to warn the operator before the shut-down level is reached.
1.2.3 Warning
A warning message also appears if:
- On water-cooled compressors, the cooling water outlet temperature exceeds the warning level.
- On Full-Feature compressors, the dewpoint temperature exceeds the warning level.
1.3 Service warning
A number of service operations are grouped in plans (called Service plans A, B and C). Each Service
plan has a programmed time interval. If a time interval is exceeded, a message will appear on display
(12-Fig. 2.1) to warn the operator to carry out the service actions belonging to that plan.
1.4 Automatic restart after voltage failure
The regulator has a built-in function to automatically restart the compressor if the voltage is restored
after voltage failure. For compressors leaving the factory, this function is made inactive. If desired,
the function can be activated. Consult Atlas Copco.
Warning
If activated and provided the module was in the automatic operation mode, the compressor will
automatically restart if the supply voltage to the module is restored within a programmed time
period.
The power recovery time (the period within which the voltage must be restored to have an automatic
restart) can be set between 10 and 3600 seconds or to Infinite. If the power recovery time is set to
Infinite, the compressor will always restart after a voltage failure, no matter how long it takes to restore
the voltage. A restart delay can also be programmed, allowing e.g. two compressors to be restarted
one after the other.

1) The settings for the Proportional band and Integration time are determined by experiment.
Altering these settings may damage the compressor. Consult Atlas Copco.
2) Once the compressor is automatically stopped, it will remain stopped for the minimum stop time,
whatever happens with the air net pressure. It is recommended to program this setting at
minimum 20 seconds to prevent too-short stopping periods. If a lower setting should be required,
consult Atlas Copco.
3) See section 1.4.
4) In case of LAN control. See section 15. Consult Atlas Copco.
5) The regulator does not accept illogical settings, e.g. if the warning level is programmed at 95 °C,
the minimum limit for the shut-down level changes into 96 °C. The recommended difference
between the warning level and shut-down level is 10 °C.
6) Use Atlas Copco oil separators. The recommended maximum pressure difference is 1 bar.

7) Is the time period during which the warning signal must exist before the warning message
appears.
8) Full-Feature version is the Workplace version with integrated air dryer.
9) Is the time period during which the warning signal is ignored after starting to allow the dryer to
reach the dewpoint temperature.
10) Is the period after starting which must expire before generating a warning. This setting should be
less than the setting for delay at signal.
11) Recommended minimum setting: 70 °C. For testing the temperature sensor, this setting can be
decreased to 50 °C. Reset the setting value after testing.
