## Description

CYRIX-LI-CT 12/24V-230A COMBINER

Review: Habe einen Ersatz für meinen defekten Septor 1274 duo gebraucht und bin durch Zufall auf dieses Gerät gestoßen. Ich wollte die Version mit LED haben. Leider ist die Dokumentation, besonders was den Lieferumfang betrifft, sehr dürftig. Tatsächlich ist nur das Kabel für die Überbrückungsfunktion enthalten, jedoch ohne Schalter. Die Anschlußschrauben haben 8mm Durchmesser (Muttern sind natürlich dabei), also bitte beim Kauf der Kabelschuhe berücksichtigen. Dass mein Septor defekt ist habe ich übrigens erst bemerkt, nachdem ich an beide Batterieeinheiten (1 x Starter, 2 x Verbraucher, parallel geschaltet) jeweils einem Victron Smart Battery Sense zur Überwachung angeschlossen habe. Daher weiß ich auch, dass der Cyrix zuverlässig schaltet.
Review: Funkar fint.. bra uppfinning

## Features

- Intelligent battery control to prevent unwanted switches:. The Cyrix-ct 12/24 also takes into account the general trend (increase and decrease in tension) and it reverses a previous action only if the trend has reversed for a certain period of time. The delay time depends on the voltage deviation from the trend.
- Overheating protection (due to long-term overload): Victron Energy Cyrix disengages in case of excessive contact temperature and re-engages after cooling.
- Parallel connection in case of emergency (StartAssist): The Cyrix can also be switched on with a push button (the Cyrix stays on for 30 s) or with a switch to connect the batteries in parallel manually. This can be very useful in an emergency when the starter battery is discharged or damaged.

## Questions & Answers

**Q: What is diameter of the large posts?**
A: 5/16"

**Q: What is the purpose of the led? on when batteries are connected?**
A: LED status indication
LED on: engaged 
LED 10 s flash: disengaged
LED 2 s flash: connecting 
LED 2 s blink: disconnecting
LED 0,25 s blink: alarm (over temperature; voltage > 16 V; both batteries < 10 V; one battery < 2 V)
(multiply by two for 24 V)

**Q: If I have 24v aux bank and 12v starter battery, will this work?**
A: No it will not; banks of different nominal voltages cannot be combined. You should use a DC-DC charger instead - one that is set up to take 12v nominal input and output 24v nominal.

**Q: Can this act as a voltage regulator?**
A: No, this device is voltage *triggered*, but does not regulate voltage in any way.

Easy installation. Instructions a bit vague, need to definitely connect the ground wire (duh). The ignition start exciter wire is optional. Don't forget to have the proper fuse/breaker for the power transfer cable. Have run this for 5 hours currently and it is functioning as designed.
