Output Alarm Truth Table
Water Detected | Oil Leak Detected | Relay Output Contact |
NO | NO | Open (no alarm) |
NO | YES | Closed (alarm) |
YES | NO | Open (no alarm) |
Water detected first. | Then an oil leak. | Open (no alarm)** |
Water detected second. | Oil leak detected first. | Closed (alarm)* |
* If the sensor is detecting an oil leak before water is detected, the output relay will remain ON. However, if water is detected before an oil leak, the relay will remain OFF**. Until the water has evaporated the relay will remain OFF, and only turn ON if oil is present thereafter
** The sensor will also detect oil in water providing enough oil is present to force the water away from the optical sensor.
