1.0 OVERVIEW
1.1 For help locating subjects in this document, a section index is provided on page 68.
A glossary of technical terms begins on page 66.
1.2 The Altronic DE-3000+ controller system is an electronic, microprocessor-based
system designed to sense various analog and digital input points to control and
monitor industrial compressors. The system is field-programmable using a PC
and the supplied terminal program and contains a non-volatile memory to store
the setup. A panel-mounted 10" color MIDAS HMI serves as the user interface.
The DE-3000+ provides for both the safety shutdown functions needed to pre-
vent unnecessary damage to remotely-operated equipment and the closed-loop
automatic control functions needed to optimize their efficiency of operation.
The DE-3000+ also provides for remote data acquisition and supervisory con-
trol in a compact, low cost package for industrial compressor applications. The
optimization strategies available for the management of compressor throughput
include automatic prime mover speed setting as well as capacity control. On
rotary screw compressors, capacity control can be done via suction throttling,
or using an internal gas bypass technique employing poppet valves, turn valves
or slide valves. On reciprocating compressors, capacity can be controlled us-
ing external gas bypass loops or pressure regulation techniques. A wide range
of output options, including both analog current loops and digital outputs, are
provided to interface with the large variety of actuation systems currently in use.
In addition, automatic load limiting based upon prime mover power capabilities
or other application specific limitations, such as cooling capacity, are readily
implemented. There are also AUTO START and OEM ENGINE CONTROL options
that are enabled using the terminal program.
1.3 The DE-3000+ has four components: 10" color MIDAS HMI (G10S0000),
computer module (DE-3000+), terminal module (691171-1), and power supply
module (691122-1). The MIDAS HMI and the computer module communicate
via the Ethernet port using a CAT 5e cable. The computer module connects to
the terminal module via a DB-25 cable. An additional terminal board may be
added for 30 extra channels (691171-2) or 15 extra channels (691175-2). This
increases the channel selections from 1-30 to 1-60 or 1-45 respectively.
To download the terminal program, a DB-9 cable must be connected to the to
the DE-3000+.
2.0 10" COLOR MIDAS HMI
2.1 The 10" color MIDAS HMI serves as the user interface for the DE-3000+ sys-
tem. It is a VGA color standard touchscreen (640 x 480) outdoor model. The
MIDAS HMI has one 10/100 Base-TX Ethernet Port and three fully isolated Se-
rial Communication Ports (two RS-232 and one RS-422/485). In addition, the
MIDAS HMI has one USB Type B Port and two High-retention USB Host Ports.
WARNING: THE CONTROLLER SYSTEM
MUST BE CONFIGURED PRIOR TO USE
ON A COMPRESSOR SYSTEM. REFER-
ENCE THE PROGRAMMING INSTRUC-
TIONS (PAGE 43) FOR INSTRUCTIONS
DESCRIBING HOW TO CONFIGURE THE
CONTROLLER FOR THE SPECIFIC AP-
PLICATION. VERIFY THE PROGRAM IN
NONVOLATILE MEMORY (THE EEPROM)
PRIOR TO STARTING THE SYSTEM.
WARNING: DEVIATION FROM THESE
INSTRUCTIONS MAY LEAD TO IMPROP-
ER ENGINE OPERATION WHICH COULD
CAUSE PERSONAL INJURY TO OPERA-
TORS OR OTHER NEARBY PERSONNEL.
NOTE: THE DE-3000+ REQUIRES
TWO 10-32VDC, 0.2A (MAX) POWER
SOURCES, ONE FOR THE POWER SUP-
PLY BOARD AND THE OTHER FOR THE
COMPUTER MODULE.
