Battery voltage monitoring to prevent unwanted switching: Some battery separators (also called voltage controlled relay or separation relay) disconnect a battery in the event of a short but high current. Sometimes a battery disconnector also fails to connect a large but uncharged battery bank because the DC voltage immediately drops below the disconnect value once the batteries are connected. The software of the Cyrix-ct 12/24 does more than just connect and disconnect based on battery voltage and a set time delay. The Cyrix-ct 12/24 looks at the general trend (increase or decrease in voltage) and only adjusts the most recently performed action if the trend has changed during a certain time frame. The time delay depends on the voltage deviation from the trend. (for battery separators with multiple connection/disconnection profiles, see Cyrix-i 400) Long bolts to allow connection of more than one power cable Cyrix 12/24-120: 13 mm (M6) Cyrix 12/24-230: 16 mm ( M8) Protection against overheating (due to prolonged overload e.g.) The Cyrix disconnects in case of excessive contact temperature and restores the coupling after it has cooled down again. LED status indication (only with Cyrix 12/24 230) LED on: connected LED lights up for 10 sec.: disconnected LED lights up for 2 seconds: connection is being made LED flashes every 2 seconds: connection is broken LED flashes every 0.25 sec.: alarm (overtemperature; voltage > 16V; both batteries < 10V; one battery < 2V) (multiply by 2 for 24V) Automatically determine 12/24 V The Cyrix-ct 12/24 automatically detects the system voltage. No voltage loss The Cyrix battery separator is an excellent alternative to diode charging current isolators. The main feature is that the voltage loss is practically nil, so the output voltage of alternators or battery chargers does not need to be increased. Priority for the starter battery It is common practice to connect the alternator directly to the starter battery. The accessory battery and possibly also a bow thruster battery and other batteries are all connected to the starter battery with a Cyrix battery separator. When the Cyrix determines that the starter battery has reached the coupling voltage, the Cyrix ensures that all batteries are charged in parallel. Bidirectional voltage measurement and power supply from both batteries The Cyrix measures the voltage of both connected batteries. As a result, the Cyrix also connects the batteries in parallel when, for example, the accessory battery is charged by a battery charger. The Cyrix-ct 12/24 has a double power supply. This ensures that the Cyrix closes if the voltage of one battery is too low to operate the Cyrix. To prevent unexpected operation during installation or when one battery is disconnected, the Cyrix-ct 12/24 will not close if the voltage of one of the two battery connections is lower than 2V (with a 12V battery) or 4V ( with a 24V battery). Parallel connection in case of emergency (Start Assist) The Cyrix can also be switched on by means of a push button (the Cyrix remains active for 30s) or a switch to manually connect batteries in parallel. This is especially useful in an emergency when the starter battery is empty or broken.
