A.1 Safety Precautions
A.1.1 General Precautions
1. The operator must employ safe working
practices and observe all related local work
safety requirements and regulations.
2. If any of the following statements does not
comply with local legislation, the stricter of
the two shall apply.
3. Installation, operation, maintenance, repair
work must only be performed by authorized,
trained, specialized personnel.
4. Before carrying out any maintenance, repair
work adjustments or any other non-routine
checks, stop the device. In addition, the
power isolating switch must be opened and
locked.
5. Use only correct tools for maintenance and
repair work.
6. Use only genuine

A.2 Introduction
The ES-6 is a stand alone Central Control
System. The Central Control System regulates
the net pressure within programmable limits
by starting, loading, unloading and stopping
the compressors connected according to the
programmed sequence. It also controls the
regeneration cycles of the desiccant dryers while
monitoring the dew point and CO levels in the
discharge air.
The Central Control System distributes the
running time between multiple compressors
connected in the CAN network (see A.3 CAN
Network Connection). To connect Elektronikon
III controlled compressors a dongle is required
(see FIG A.2). The status of each compressor can
be checked on the control screen. Operating
parameters are accessible via the menu.
A.2.1 Single Point Pressure Measurement
The ES-6 controls the system pressure by
means of a pressure transmitter. Depending
on the reading of the pressure transmitter the
controller will start and stop the compressors in
the network in order to keep the pressure within
the limits of the pressure band.
A.2.2 Sequence Management
In order to maintain the system pressure, the
ES-6 has the following control functions:
1. Position of the measured pressure to the
pressure band
2. Priority scheme check
3. Equal wear check
4. Compressor availability check
Depending on the status of these functions the
ES-6 will determine the sequence of starting and
stopping of the connected compressors.

WARNING!
All responsibility for any damage or
injury resulting from neglecting these
precautions, or non-observance of the
normal caution and care required for
installation, maintenance and repair,
even if not expressly stated, will be
disclaimed by the manufacturer.
