Elstat Ems 55 Advanced User Manual New __top__ <CONFIRMED>

The Elstat EMS 55 Advanced is a self-learning energy management system used primarily in commercial refrigeration to reduce energy consumption by up to 35%. It achieves this by learning the operating patterns of a business and automatically switching between Active and Stand-by modes based on foot traffic and door activity. Core Operating Modes

The controller manages the cooler through a constantly updating 7-day schedule, divided into 30-minute intervals.

Active Mode: Standard operation where the cabinet holds the product at the programmed temperature and lights are on.

Stand-by Mode: An energy-saving state where lights are turned off, and the compressor cycles at a higher internal temperature.

Defrost Mode: The compressor shuts off while the evaporator fan continues to run to clear ice buildup. Essential Technical Specifications Appliance Temp Range Condenser Temp Range Power Supply AC input / AC output transformer IP Rating Front: IP45; Rear: IP24 Relay Ratings Compressor: 10A; Fan: 4A; Light: 500W Advanced Programming & Menu Navigation

To modify settings, you must bypass the security lock using a specific "password sequence". Access Menu: Press and hold Set until PAS appears. Enter Sequence: Press Set (Snowflake) 3 times. Press Up 2 times. Press Down 1 time. Press Defrost (Water drops) 4 times.

Navigate: If successful, PS will be displayed. Use Up/Down to scroll through parameters like PEr (Perishable mode). Diagnostic & Troubleshooting Codes The LED display provides real-time status and error alerts:

USE: Standard display indicating the controller is in normal use. 888: Displayed during a test routine.

Hr (Half Reset): Used to clear the self-learning matrix if business hours change significantly. elstat ems 55 advanced user manual new

PF1 / PF2: Typically indicates a probe failure (Appliance or Condenser sensor). dEF: Indicates the unit is currently in a defrost cycle. Maintenance & Resets

Half Reset: Access the menu, scroll to Hr, and re-enter the password sequence to clear the learning memory.

Self-Test: Access the tst menu to manually trigger the compressor, evaporator fan, and lights for functional verification.

Motion Sensor Check: While in test mode (Pir), wave your hand in front of the sensor; the displayed number should increase if the PIR is functioning correctly. ems-55-controller.pdf

The Elstat EMS 55 Advanced is an intelligent energy management controller designed for commercial refrigeration. It uses self-learning technology to predict store opening times and adjust cooling modes to save energy during closing hours. 1. Key Operating Modes

The controller automatically cycles between three primary states based on a learned 7-day schedule:

Active Mode (USE): The cooler is ready for customer use. Lights are on, and the product is maintained at the optimal serving temperature (e.g., 36°F–38°F).

Standby Mode (---): Occurs during closing hours. Lights are off, the evaporator fan cycles, and the temperature is allowed to rise to a more economical set point (approx. 50°F) to save power. The Elstat EMS 55 Advanced is a self-learning

Defrost Mode (dEF): The compressor stops while the evaporator fan runs to clear ice buildup. This is a pre-programmed maintenance function. 2. Accessing the Configuration Menu

To change settings or perform resets, you must enter the "key dance" password sequence: Press and hold SET until PAS appears on the display. Enter Password Sequence: Press SET (Snowflake) 3 times. Press UP arrow 2 times. Press DOWN arrow 1 time. Press DEFROST (Water drops) 4 times.

The display should now show PS, confirming you are in the parameter menu. 3. Common Settings & Resets

Half Reset (Hr): Clears the self-learning matrix so the controller can re-learn a new business schedule. Navigate to Hr in the menu and enter the password sequence again to reboot.

Perishable Mode: If enabled (setting 1), the unit will not enter standby mode, maintaining a constant low temperature to protect high-risk food items.

Test Routine (tst): Used by technicians to verify that the compressor, lights, and fans are functioning correctly. 4. Troubleshooting Display Codes 888 Initial Power-up Normal startup sequence. USE Ready Mode System is operating normally for customers. --- Standby Mode System is in energy-saving mode. PF1 / PF2 Probe Failure

Check connections for appliance (1) or condenser (2) sensors. dEF Defrosting Normal cycle; wait for it to complete.

Executive Summary: Elstat EMS-55 Advanced Controller Elstat EMS-55 Advanced

is an energy management system designed to optimize refrigerator and chiller efficiency through automated scheduling and sensor-based monitoring. By learning usage patterns, the system balances cooling performance with significant energy savings during closing periods. combustioncontrols.pk Core Functionality & Logic Adaptive Learning: The controller automatically learns a seven-day schedule split into 30-minute intervals. Operating Modes: Time periods are categorized into three distinct modes: Normal cooling for standard business hours. Reduced energy mode during closing periods. Intermediate state used for data collection. Sensor Integration:

The schedule is continuously updated based on real-time data from motion sensors door opening combustioncontrols.pk User Operations & Configuration

For advanced users needing to modify settings or perform maintenance, the controller utilizes a specific input sequence known as a "key dance" to access hidden menus. JustAnswer Accessing Service Menus ("Key Dance") Enter Password Mode: Set button (snowflake icon); the display should read (3 beeps). (2 beeps). Down Arrow Water Drops (4 beeps). The display will show , indicating successful entry into programming. JustAnswer Performing a Half Reset Navigate using the Down Arrow until the display reads Snowflake key to confirm. The display will revert to JustAnswer Technical Specifications & Installation Soft Start:

Includes a soft-start function to manage compressor load during power-up. Perishable Mode: If set to perishable mode, the unit is programmed for no standby mode

to ensure constant cooling, though lighting and compressor cycling are still optimized. Troubleshooting:

Common issues include lighting failures, often related to internal fuses or circuit breaker malfunctions. A dedicated light test

can be initiated through the EMS-55 menu to verify sensor-light integration.

Modbus RTU for BMS Integration

For facilities using a Building Management System (BMS), the new manual dedicates an entire chapter to Modbus RTU communication. Key settings:

Maintenance & Cleaning

Step-by-Step Advanced Calibration:

  1. Prepare an ice bath (0°C) and a hot water bath (50°C or your process high limit).
  2. Insert Probe 1 into the ice bath. Wait for stability (5 minutes).
  3. From the advanced menu, select CAL > P1 L (Probe 1 Low).
  4. Adjust until display reads 00.0.
  5. Move the same probe to the hot bath. Select P1 H.
  6. Adjust until display matches the certified reference.
  7. Repeat for Probe 2.

Critical warning from the new manual: Do not perform advanced calibration without a certified reference probe. The EMS 55 allows up to ±5°C offset; exceeding this suggests a damaged sensor.
