The Micronova ES99 (Atlas Copco part #2202842000) is a control module primarily used for energy management in rotary screw air compressors, such as those from Atlas Copco, Chicago Pneumatic, and Ceccato. Technical Specifications Power Supply: 12 VAC, 50/60 Hz, 250 mA.
Physical Dimensions: Approximately 250 mm x 155 mm x 130 mm (LxWxH).
Interface: Features an LCD display for real-time monitoring of pressure, temperature, and service alerts.
Application: Designed to monitor, control, and protect compressor systems via automatic start/stop and safety shutdowns. Operational Indicators and Warnings
The ES99 provides visual feedback through an LCD or LED interface to signal system status or malfunctions:
Safety Protections: It monitors for motor thermal protection, power supply phase errors, and compressor overheating.
Remote Control: Features a dedicated dip switch setting to activate or deactivate remote operation.
Auto-Restart: Can be configured via dip switches to automatically restart the system after a power interruption. Wiring and Connectivity (Pinout CN1)
Standard configurations for the ES99 (often shared with the ES3000 series) include the following terminal connections: Overload Motor: Pins 4 – 3 (Normally closed).
Rotation Direction: Pins 5 – 3 (Normally closed; signals wrong rotation).
Oil Temperature: Pins 6 – 3 (Normally closed; signals over temperature).
Pressure Switch: Pin 10 – 3 (Open if P > Pmax; Closed if P < Pmin). Emergency Push Button: Pin 12 – 3 (Normally closed). Maintenance and Verification ES99 Control by MICRONOVA - Radwell International
Micronova ES99 is a specialized control module primarily used in industrial equipment, most notably as a controller for Atlas Copco air compressors
. Verified user manuals and technical documentation for this device typically cover its installation, wiring, and operational parameters for energy-saving industrial applications. Radwell International Overview of the Micronova ES99 Controller
The ES99 functions as an energy-saving control module designed to manage industrial machinery. According to its specifications, it typically operates at
with a frequency of 50/60 Hz. Although discontinued by some manufacturers, it remains a critical component in many legacy air compressor systems, such as the Atlas Copco 2202842000. Radwell International Key Technical Specifications Voltage Requirement Power Consumption Primary Application : Control and monitoring of air compressors. Manufacturer : Micronova (Italy). Radwell International Verified Manuals and Resources
To properly configure or troubleshoot the device, you should refer to these verified technical documents: Instruction Manuals
: Comprehensive guides for the ES99 are available on document-sharing platforms like Scribd (Es99 Manual) Wiring Diagrams
: For integration into compressor systems, detailed wiring diagrams are often included in broader Atlas Copco service manuals. Replacement & Support : Since the part is discontinued, retailers like Radwell International
provide technical data and warranty-backed replacements for the module. Radwell International Common Troubleshooting Steps Power Supply Check
: Verify that the incoming voltage is a stable 12 VAC. Fluctuations can cause the controller to reset or fail. Wiring Inspection
: Ensure all terminal connections match the specific wiring diagram for your compressor model. Sensor Validation
: The ES99 relies on pressure and temperature sensors; ensure these are functioning correctly to avoid false error codes. or a specific troubleshooting guide for a particular compressor model? Es99 Controller | PDF - Scribd
