1.3.1 Elektronikon regulator (E1-Fig. 1.1)
The regulator has following functions:
Controlling the compressor
The regulator matches the compressor output to the air
consumption by speed regulation of the motor.
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; consult the "User manual
for Elektronikon regulator", section "Modify settings
submenu".
Note: to prevent the safety valve from opening too frequently
on 13 bar compressors, the setting of the direct stop setpoint
should never be more than 1 bar.
Protecting the compressor
If the compressor element outlet temperature exceeds the
programmed shut-down level, the compressor will be stopped.
This will be indicated on the control panel (Fig. 1.7). The
compressor will also be stopped in case of overload of fan
motor (4-Fig. 1.4).
If the compressor element outlet temperature exceeds a
programmed value below the shut-down level, this will also
be indicated to warn the operator before the shut-down level
is reached.
Service plans
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. 1.7) to warn the
operator to carry out the service actions belonging to that plan.
See section 4.1.
Automatic restart 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.
