The resultant flicker of the lights will alert the driver of the system overload. When the main battery voltage rises above 13.3 volts again, the relay will again close in about 2 seconds to retry charging the auxiliary battery. This might happen when the alternator is not able to supply sufficient current to all the loads and charge the auxiliary battery. If the voltage should drop below 12.0 volts for more than two seconds while the engine is running, the relay will drop out. When the ignition switch is turned off, the relay will open immediately. When this voltage goes above 13.3 volts for approximately 12 seconds, as happens when the engine is running normally (normal alternator output voltage is approximately 14.4 volts), it will close the isolator relay providing charging current to the auxiliary battery. Bi-Directional Isolator Relay Delay Offers A New Approach To Charging Batteries In An RV Application. It operates by sensing the voltage on the main 12 volt system. There are three (3) wires to connect to the delay unit: one from an ignition switched 12 volt source, a ground and the isolator relay coil. It operates in combination with a conventional continuous duty cycle isolator relay that has been used by a number of vehicle manufacturers. The unit is fully encapsulated in a plastic enclosure for mounting in the engine compartment with two screws. This allows the use of self-exciting alternators and lets the engine briefly warm up prior to placing the load of a heavily discharged auxiliary battery on the alternator. Unlike diode isolators, this system provides an engine driven alternator with main battery before connecting the auxiliary battery. Intellitec’s Battery Isolator Relay Delay offers a low cost, reliable approach to charging multiple batteries. In addition, this configuration comes with an IP67/X9K dust-tight, waterproof rating and has negative disconnection.Intellitec Isolator Relay Delay 00-00629-120 If the voltage on either one is above 13.3 volts, indicating the battery is being charged, it closes the isolator relay, paralleling the batteries, charging both. It also allows the use of self-exciting alternators. It provides a delay to allow the engine to briefly 'warm up' and to recharge the main battery before placing the heavy load of a discharged auxiliary battery on the alternator. This model of the remote-control relay (08070600) has a 4-way DIN connector as well as a time delay feature. The Battery Isolator Relay Delay/E is a reliable approach to charging multiple batteries on a vehicle. This bi-stable relay consumes no power in the ON or OFF states, which makes it well-suited to battery disconnect applications. Ideal for commercial vehicles and trucks as well as marine applications, the 08070000 Series 250A SPST Bi-Stable Remote-Control Battery Isolation Relay is a current isolating electrical switch with mechanical ON-OFF position.
