If the ignition switch is on, the control allows the voltage to drop below 12.0 volts for approximately 5 seconds, before the solenoid is opened to insure the alternator’s full output is available for important chassis functions. This might occur when the converter is heavily loaded. If the ignition switch is off and the battery voltage drops below 12.8 volts for approximately 5 seconds, the solenoid is opened to prevent the chassis battery from being discharged by the coach loads.
(normal charging voltages are from approximately 13.8 to 14.4 volts.)Īfter the solenoid has been closed, the system continuous to sense the voltage. Anytime either battery voltage goes above 13.3 volts for approximately 5 seconds, the solenoid closes. When either battery is being charged, the controller will close the isolator solenoid, connecting the two batteries together, charging them both. The Intellitec’s Bi-Directional Isolator Relay Delay – Diesel operates by sensing the voltages on both batteries. In order to use this type solenoid for continuous duty, the controller will engage it with full voltage and then reduce the coil voltage to approximately 4 volts to hold it in. To connect the two batteries together under proper conditions, it operates in combination with an intermittent duty solenoid, similar to ones used as diesel starter solenoids. The unit is housed in a plastic enclosure for mounitng in an engine compartment. The load on the accessory battery does not drain the starting battery. One battery is used to start the engine and the other is used to run the accessories.

The controller also senses heavy loads on either battery to prevent the wrong battery from being inadvertently discharged. The diode type battery isolator uses semiconductor diodes to split the current from the alternator or generator and charge 2 or more batteries at the same time. If neither battery is being charged, the batteries are fully isolated. When the coach is plugged into shore power, both batteries will be charged from the converter. When the coach is being driven, both batteries will be charged from the engine’s alternator. Unlike proper systems that only allowed charging the RV battery from the engine’s alternator, the Bi-Directional Isolator Relay Delay – Diesel chargers both batteries when either one is being charged. Adding a small dash-mounted switch will allow emergency starts of diesel engines, requiring up to 800 amps of starter current. Intellitec’s Bi-Directional Isolator Relay Delay – Diesel offers a new approach to charging batteries in an RV which uses an alternator.

The internal contacts of the Blue Sea Systems® 762X series can be cleaned in the field if necessary.Intellitec’s Bi-Directional Isolator Relay Delay – Diesel #00-00839-000 This is usually the number one failure of all of these units, the added resistance will rob you of available power and generate excessive heat in the units. In fact, a high current relay needs high current to keep the contacts clean, there is generally a minimum wetting current needed to keep the contacts from building up resistance. That specification is usually made with high current loads intended. While some units have twice the switch cycles listed, the problem isn’t quite as simple as that.
This is because this is also a common area of failure. You may have seen one of the common specifications I have listed is switching cycles. So, they should be able to disconnect if your overall load was too high and the alternator could not keep up with the load. All these units work pretty much on the same principle, monitor the voltages of the batteries and connect and disconnect at determined setpoints.
