Secop 105N4120 NLV-CN Core Functions Controllers Compressors

Product Usage Instructions

• Ensure a minimum airflow of 3 m/s for both the compressor and electronic units. Direct airflow for electronics to the heat sink.
• Fasten the copper shield of the controller cable properly to the clip at the compressor for optimum EMC performance.
• Connect the compressor and controller to PE (Protective Earth) to avoid electrical hazards.
• Collect all protective earth lines to one star point to prevent loop currents that could cause electronic component issues.
• Installation should only be performed by trained personnel.
• Do not remove the controller cover when the unit is powered on.
• Disconnect from power and wait 30 seconds before accessing terminals.
• Ensure the signal connection cable length does not exceed 3 meters.
• Detailed instructions on thermostatic operation, frequency speed control, DWI serial communication, and defrost control are provided in the manual.
• Refer to the manual for detailed technical data on the controller and compressors.
• Dimensions of the product are outlined in the manual for reference.
• Details on how to order additional units or replacement parts can be found in the manual.

INSTALLATION

WARNING!

• To remove a compressor from a system, the tubes must be cut.
• Never use a torch to remove brazed tubes.

Brazing on Suction Connectors (Direct Intake)

• Refer to Product Bulletin:
• Brazing on Suction Connectors (Compressors with Direct Suction Intake)

Airflow

• Ensure proper airflow of 3 m/s at both compressor and electronic units.
• The airflow for the electronics must be directed to the heat sink.

Earthing the Compressor and Controller

• For optimum EMC performance, the copper shield of the controller cable must be fastened properly in the clip at the compressor.
• The compressor and controller must be connected to PE (Protective Earth) to avoid risk of electrical hazard.
• All protective earth lines, PE, in the application must be collected to one star point. This prevents loop currents, which could cause problems concerning the electronic components, communication lines, and sensors. The star-point is normally a screwed terminal on the chassis.

Wiring Diagram

• Installation must only be done by trained personnel.
• Do not remove the cover of the controller when the unit is powered on.
• Disconnect from power and wait 30 seconds before accessing terminals.
• The maximum cable length should not exceed 3 meters for signal connections.
• A cable length of more than 3 m could alter the EMI performance.
• Signal lines must be separated from power lines.

Wiring for Thermostatic Operation

• For optimal hot-gas defrost performance, the relay output of the controller should be connected to the DEF input of the controller.
• This ensures that the compressor operates at full speed when the hot gas valve is activated.

Wiring for Frequency Operation/DWI Communication

SPEED CONTROL

The Secop Core Functions controller is equipped with three different inputs for speed control to ensure easy integration.
Almost any temperature controller can be used to control the speed without needing to change the setup.
The Core Functions controller has automatic input detection and will automatically select the input that is active.

1. Frequency signal.
2. Thermostatic operation with AEO, Adaptive Energy Optimization.
3. DWI, Dual Wire Interface with separated RX and TX lines.
   • If more signals are connected, the input with the highest priority (1–3) will be used.
   • DWI input has the lowest priority and can be used for monitoring in combination with the other inputs.
   • If DWI sends an active start command, the DWI input will change priority to 1 and overrule all other input signals.

Thermostatic Operation with AEO

• AEO is the only control mode where there is no direct relation between speed and input signal.
• The speed is automatically calculated based on the runtime ( time between cut-in and cut-out).
• The AEO can be interfaced by a normal thermostat or relay.

% Runtime	% Speed
100	105
110	110
120	120
140	130
160	140
190	180
220	225

Advantages of the AEO:

• Easy to interface.
• Mechanical thermostat.
• Electronic control with relay output.
• Perfect for applications with stable conditions, such as freezers, catering equipment.

The AEO operates with a target runtime and will automatically adapt the speed until the target runtime is met.

• If the compressor runtime is shorter than the target time, the speed in the next cycle will be reduced.
• If the runtime is longer than the target time, the speed in the current cycle will be increased until the cut-out is reached. The next cycle is calculated as the average speed for the last cycle.

Frequency Speed Control

The speed can be controlled by applying a low-voltage frequency signal to the frequency input

• The speed is changed linearly between 66 Hz and 150 Hz.
• The frequency of 66 Hz corresponds to 2000 rpm, 150 Hz to 4500 rpm (30 rpm/1 Hz by default).
• If the frequency is between 10-50 Hz, the compressor stops.
• The frequency signal should have a voltage of 5–12 V and a duty cycle of 50%.

DWI Serial Communication

• The DWI, Dual Wire interface, is a bidirectional communication protocol that allows the temperature controller to communicate with the compressor controller.
• In addition to speed, the temperature controller can get different information from the controller, such as power consumption, actual speed, electronic temperature, and fault status.
• The communication interface is shared with the frequency interface. A full description of the interface and a list of supported commands may be requested from Secop.

Defrost Control with AEO

When variable-speed compressors are used in self-adapting capacity modes, defrosting may not work properly since the compressor speed cannot be controlled during defrost: The compressor lacks capacity for hot gas and the following pull-down.
To improve defrost when AEO is used, the Core Functions controller has an extra input that can be connected to the defrost relay output of the temperature controller.

• Hot-gas defrosting: When the defrost and AEO inputs are activated simultaneously, the Core Functions controller switches to a defined speed (defrost low speed). After a defined defrost low-speed time, the compressor will increase to defrost high speed until the defrost is completed.
• The two-speed defrost is a new feature of all next-generation controllers to avoid liquid refrigerant inside the compressor.
• Electrical defrosting: When only the defrost input is activated, the compressor will remain stopped, but the information is used to trigger pull-down after defrosting.
• After defrosting, the Core Functions controller will run the first cycle at high speed to ensure that the heat is removed as fast as possible.
• After the pull-down, it reverts to the speed it had before defrost.
