ABSTRACT:
The oil detecting switch includes a light oil float switch, a water float switch and a heavy oil float switch. When the light oil float switch is closed, a relay is activated energizing a light oil indicator light and its associated coil. The coil is part of a relay which inhibits pumping action. When the water float switch is activated, the inhibiting relay is bypassed so that pumping action can continue. When the heavy oil float switch is activated and closed, a relay is activated which energizes a heavy oil indicator light and its associated coil. The coil is part of a relay which inhibits pumping action. The light oil indicator light, its associated coil and the water indicator light are bypassed when the heavy oil float switch is activated. The status of the float switches is monitored by an analog-to-digital converter associated with a Remote Monitoring System Transmitter.
