FUNCTION

The Redarc LCA1224 is used in a 12V or 24V automotive system to monitor radiator coolant level and provide a visual and audible alarm if the coolant falls below the chosen level. It can give warning of a sudden loss of coolant (Eg from a burst radiator hose) and allow the operator to stop the vehicle and switch off the engine, to prevent any damage due to over-heating.

FEATURES

• AC Sensing: The probe is supplied with AC, so it does not produce electrolysis to cause cooling system corrosion.
• Broken Wire Detection: If the wire to the probe is broken it will sound the alarm.
• Universal supply: Suitable for 12V or 24V, negative or positive earth vehicles.
• Self-test: On ignition turn on, it performs a self test by internally duplicating low coolant or a broken probe wire. In self-test, the LED flashes twice and the beeper sounds 4 times.
• Anti-slosh delay: If the radiator is not quite full and coolant sloshes around, the LED flashes after ½ second but the beeper will not sound for 3-4 seconds. So there is a visual reminder to top up but no annoying beeps.
• External warning lamp: If the LCA1224 is to be mounted where it cannot be seen by the driver, an external warning lamp output allows a dashboard lamp to be used. The maximum rating for an external lamp is 0.5A max.
• External warning buzzer: If the LCA1224 is to be mounted where it cannot be heard by the driver, an external warning buzzer output allows a louder (or more suitably located) buzzer to be used. The maximum rating for an external buzzer is 0.5A max.
