1. The sampling/sensor assembly (figure 3, item 1) samples the OWS effluent, measures the oil content, and
generates electrical signals for the system indicators, alarms, and control relays.
2. The remote indicator (alarm) assembly (figure 3, item 2) is the remote control and indicator unit for the OCM
system.
3. The remote relay assembly (figure 3, item 3) is the relay control link between the OCM and the diverter
solenoid valve on the OWS discharge piping. The diverter solenoid valve directs the effluent either over-
board or to the Oily Waste Tank (OWT).
