1.0 OVERVIEW
1.1 For help locating subjects in this document, a section index is provided on page 37.
1.2 The Altronic DE-2200 compressor monitor system is an electronic microprocessor-based
system designed to sense various analog sensors, digital switches and industry standard type
J or K thermocouples to monitor industrial compressors. The system is field-programmable
using a PC (personal computer) and the supplied DE-2200 terminal program and contains a
non-volatile memory to store the setup. Serial communications provide an interface to PC’s,
PLC’s, modems and satellite uplinks for remote communication. A backlit 4x20 LCD character
display shows system status, programmed engine/motor and compressor parameters and
channel labels. A front mounted keypad serves as the user interface. The DE-2200 provides
the safety shutdown functions needed to prevent unnecessary damage to remote operated
equipment. Additionally, the DE-2200 provides for remote data acquisition in a compact, low
cost package dedicated to industrial compressor applications.
1.3 The system consists of three main parts: a panel mounted Display Module DE-2200, a Power
Supply Module 691122-1, and a Terminal Module 691136-1. These components are
interconnected by means of Cable assembly 693115-1.
WARNING: THE MONITOR SYSTEM MUST BE CONFIGURED PRIOR TO USE ON A
COMPRESSOR SYSTEM. REFERENCE DE-2200 PI PROGRAMMING
INSTRUCTIONS, FOR INSTRUCTIONS DESCRIBING HOW TO CONFIGURE THE
MONITOR FOR THE SPECIFIC APPLICATION. VERIFY THE PROGRAM IN
NONVOLATILE MEMORY (THE EEPROM) PRIOR TO STARTING THE SYSTEM.
REFER TO SECTION 10.0 ON HOW TO VIEW THE CURRENT CONFIGURATION.
2.0 DISPLAY MODULE
2.1 The Display Module serves as the user interface for the DE-2200 system. It is in a 6.5" x 6.5"
panel mounted enclosure and consists of an alphanumeric 20-character x 4-line backlit LCD
display, a 16-key front-mounted keypad, DB-25 D-Sub and DB-9 D-Sub connectors and three
pairs of serial port indicators.
2.2 The keypad is a sealed membrane unit that contains the familiar STOP, RESET and TEST
keys as well as other keys used to navigate through channel status and description, view
process screens, and to edit the configuration.
2.3 The LCD displays a “home screen” that displays a status line along with three user
configurable analog points; typical points are speed, the suction pressure and the discharge
pressure. A “view screen”, which is available by pressing the VIEW key, displays up to eight
user configurable analog process labels, values and bargraphs of the corresponding analog
inputs. Pressing the VIEW CHANNEL key displays the channel number, its timer status,
analog value (if applicable) and the corresponding 20-character user defined label.
