The ECS-2180neo is a microprocessor-based digital controller designed for managing refrigeration systems, specifically for medium to low-temperature applications. It features three relay outputs to control the compressor, fan, and defrost functions, which can be configured for either electric or hot gas defrost. The device comes with two NTC temperature probes, one for thermostatic control of the cabinet and another for evaporator defrost control.
The primary function of the ECS-2180neo is to regulate the cabinet temperature. This is achieved by monitoring the temperature using the indoor probe. When the temperature rises to the set point plus the differential, the compressor is activated. Conversely, when the temperature drops to the set point, the compressor switches off. A visual indicator on the display shows when the compressor relay is engaged, and it flashes during a delay to prevent short cycling, ensuring the longevity of the compressor. The controller also includes a compressor short cycle protection feature, adjustable from 0 to 90 minutes, to prevent excessive starting. In the event of a probe failure, the compressor can be configured to run for a timed period (0-60 minutes) to prevent product thawing or to cycle off for a timed period (0-60 minutes) to prevent freezing.
The controller supports various defrost modes, including electric heater or hot gas defrost. For medium-temperature applications, an "off-cycle" defrost can be utilized, where defrosting occurs when the compressor is off. Defrosting is interval-timed, with the interval adjustable by the user from 0 to 90 hours. The defrost period itself is also adjustable from 1 to 90 minutes. Defrost termination can be triggered by the defrost probe reaching a set temperature (0°C to 50°C) or by the expiration of the interval period. A visual indicator on the display signifies when defrost is active. After defrost, a drip time (0-60 minutes) is allowed for condensate to drain from the coil, preventing ice buildup. The defrost status display can be configured to show the cabinet temperature, "dEF," or the start-defrost cabinet temperature during defrost and drip time.
The fan control is highly configurable. It can be set to run simultaneously with the compressor, continuously, or to stop during defrost and drip time. A "fan time delay after defrost" feature allows for a delay before the fan restarts after defrost. The fan motor also incorporates a high-temperature stop point (adjustable from -50°C to 85°C) as a safety measure to prevent the circulation of warm air within the cabinet. In some configurations, the fan operation can be controlled by the defrost sensor.
The ECS-2180neo includes comprehensive alarm features to alert users to potential issues. It supports high and low-temperature alarms for the cabinet, with adjustable alarm ranges and delay times (0-60 minutes) before activation. There are also alarms for sensor failures (cabinet, evaporator, condenser), condenser high temperature, and copy card programming failures. The buzzer can be muted by pressing any key. The alarm relay can be configured to act as either a light output or an alarm output.
The device can integrate with a door switch to manage various functions. When the door is open, the fan can be closed, and the light can be turned on or off. It can also be configured to initiate defrost when the door is open, acting as a synchronous signal input for defrost. The buzzer can be set to respond when the door is open.
The controller allows for easy adjustment of various parameters. The set point for temperature can be changed by pressing the "SET" button for 3 seconds, then using the up and down arrows to adjust the value. An administrator menu, protected by a password (default 55), provides access to advanced settings. This menu allows adjustment of parameters such as hysteresis value, compressor start minimum interval, cabinet sensor calibration, temperature set limits, maximum standby time, refrigeration minimum running time, evaporator sensor selection, defrost cycle calculation, defrost cycle interval, maximum defrost time, drip time, time delay after defrost start, defrost type, fan running mode, fan initial start time delay, fan start time delay after defrost, fan working lowest/highest temp, compressor run/stop proportional time, buzzer alarm output switch, cabinet temperature lower/upper limit alarm values, over temperature alarm time delays, and over temperature alarm deviation.
The device features an LED display that shows the current temperature and various status indicators. Indicator lights clearly show the status of setting, refrigeration, defrost, fan, defrost dripping, and door switch. These visual cues provide immediate feedback on the system's operation.
The ECS-2180neo supports a copy card function, allowing users to upload and download parameter settings. This feature simplifies the configuration of multiple devices with identical settings, saving time and ensuring consistency.
The manual provides a problem solver section to assist with common issues. It suggests checking probe connections and cleaning terminals for E1 or E2 alarms (sensor failures). It notes that probes can be extended up to 100m but may require recalibration. For LA alarms (excessive temperature), it advises allowing the controller to cool down, relocating it, or improving ventilation. If relays fail, users should check the full load amperage of the output to ensure it is within the controller's ratings. If defrost does not start, checking the coil temperature is recommended, and if the fan does not start, checking the coil temperature is advised.
The device allows for calibration of both cabinet and evaporator sensors (adjustable from -10°C to 10°C) to correct for inaccuracies due to extended probes or interference.
A comprehensive list of alarm codes is provided, detailing the reason for each alarm, such as cabinet temperature sensor failure (E1), evaporator sensor failure (E2), condenser sensor failure (E3), condenser high temperature alarm (CH), cabinet high temperature alarm (rH), cabinet low temperature alarm (rL), copy card programming failure (Er), and inconsistent data between copy card and controller (EP). This helps in quickly diagnosing and addressing issues.
The manual emphasizes several safety precautions, including installation by qualified personnel, checking supply voltage, avoiding exposure to water or moisture, disconnecting electrical connections before maintenance, and using mains filters with inductive loads in industrial applications. In case of failure, returning the device to the supplier with a detailed report is recommended.
