General description
View of the ES 4000 Standard controller
3.1
Introduction
The electronic controller has following functions:
•
Controlling the compressor
•
Protecting the compressor
•
Monitoring components subject to service
•
Automatic restart after voltage failure
3.2
Automatic control of the compressor
The controller maintains the net pressure between programmable limits by automatically loading and unloading the
compressor. A number of programmable settings, e.g. the unloading and loading pressures, the minimum stop time and the
maximum number of motor starts are taken into account.
The controller stops the compressor whenever possible to reduce the power consumption and restarts it automatically when
the net pressure decreases. If the expected unloading period is to short, the compressor is kept running to prevent too short
stand-still periods.
3.3
3.3.1
Protecting the compressor
Shut-down
If the compressor element outlet temperature exceeds the programmed shut-down level, the compressor will be stopped.
This will be indicated on the display of the controller. The compressor will also be stopped in case of overload of the drive
motor.
Air-cooled compressors will also be stopped in the event of overload of the fan motor.
Before remedying, consult the Safety precautions in the Instruction book.

3.3.2
Shut-down warning
A shut-down warning level is a programmable level below the shut-down level.
If one of the measurements exceeds the programmed shut-down warning level, this will also be indicated to warn the
operator before the shut-down level is reached.
3.4
Service warning
If the service timer exceeds a programmed value, this will be indicated on the display to warn the operator to carry out some
service actions.
3.5
Automatic restart after voltage failure
The controller has a built-in function to automatically restart the compressor when the voltage is restored after voltage
failure.
Provided the controller is in the automatic operation mode, the compressor will automatically restart when
the supply voltage to the module is restored.

34.5 Terminology
Term
Explanation
ARAVF
Activating automatic restart after voltage failure.
Power recovery time
Is the period within which the voltage must be restored to have an automatic restart. Is accessible if the
automatic restart is activated. To activate the automatic restart function, consult your supplier.
Restart delay
This parameter allows to program that not all compressors are restarted at the same time after a power
failure (ARAVF active).
Compressor element outlet
The regulator does not accept inconsistent settings, e.g. if the warning level is programmed at 95 ˚C
(203 ˚F), the minimum limit for the shut-down level changes to 96 ˚C (204 ˚F). The recommended
difference between the warning level and shut-down level is 10 ˚C (18 ˚F).
Delay at shut- down signal
Is the time for which the signal must exist before the compressor is shut down. If it is required to program
this setting to another value, consult your supplier.
Minimum stop time
Once the compressor has automatically stopped, it will remain stopped for the minimum stop time,
whatever happens with the net air pressure. Consult your supplier if a setting lower than 20 seconds is
required.
Unloading/ Loading pressure
The regulator does not accept illogical settings, e.g. if the unloading pressure is programmed at 7.0 bar(e)
(101 psi(g)), the maximum limit for the loading pressure changes to 6.9 bar(e) (100 psi(g)). The
recommended minimum pressure difference between loading and unloading is 0.6 bar (9 psi(g)).
