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)
1.1 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.
1.2 Earthing the Compressor andController
> For optimum EMC performance, the copper shield of the controller cable must be fastened properly in the clip at the compressor.
> 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.
1.3 Wiring Diagram
> Installation must only be done by trained personal.
> 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.

| 6 | Frequency/DWI | JST VH | For frequency or DWI only |
1.5 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 hotgas valve is activated.
1.6 Wiring for Frequency Operation/DWI Communication
SPEED CONTROL
The Secop Basic 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 Basic controller has automatic input detection and will automatically select the input which is active.
- Frequency signal.
- Thermostatic operation with AEO, Adaptive Energy Optimization.
- DWI, Dual Wire Interface with separated RX and TX lines.
> If more signals are connected, the input with 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.
2.1 Thermostatic Operation with AEO
| % Runtime | % Speed |
| 100 | 105 |
| 110 | 110 |
| 120 | 120 |
| 140 | 130 |
| 160 | 140 |
| 190 | 180 |
| 220 | 225 |
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 cutin and cut-out).
The AEO can be interfaced by a normal thermostat or relay.
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.
2.2 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%.
2.3 DWI Serial Communication
| Communication Specification | |
| Baud Rate: | 600 Baud |
| Start Bits: | 1 |
| Data Bits: | 8 |
| Stop Bits: | 1 |
| Parity: | No |
| Frame Size: | 5 Bytes |
| Appliance Controller: | Master |
| Compressor Controller: | Client |
| Start Bit: | 1 -> 0 (logic level) |
| Data Bits: | Inverted logic (0V -> “1”) |
| Stop Bit: | 0 -> 1 (logic level) |
| Control Mode: | Half duplex |
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.
2.4 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 Basic 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 input are activated simultaneously, the Basic 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 Basic 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.
