Intellitec 00-00956-000 RV Potted Bi-Directional Isolator Relay Delay Gas

The Potted Bi-Directional Isolator Relay Delay constantly senses the voltage on the coach and chassis batteries. If either voltage is above 13.1 volts, which indicates the batteries are being charged, the control module closes the isolator relay. This parallels the batteries, charging them both.

If the ignition is off and the coach battery voltage falls below 12.6 volts for approximately 30 seconds, the isolator relay will open to prevent the coach loads from discharging the chassis battery. When the voltage goes back above 13.1 volts for approximately 1 minute, the isolator relay will close again allowing the chassis and coach batteries to charge.

If the ignition is on, (engine running), and the voltage falls below 12.0 volts for approximately 1 minute, the isolator relay will open to prevent the coach loads form discharging the chassis battery and to insure the alternator's full output is available for important chassis functions. When the voltage goes back above 13.1 volts, for 30 seconds, the relay will close again.
