OPERATION

Civacon, Opti-Therm rack monitors are used to automatically recognize the type of overfill system (optic or thermistor signal technology) that is being used on a transport. When connected to the transport, the monitor checks the status of sensors within tanks or compartments. Overfill detection systems, such as the 8580, provide automatic warning of product overfill detection at predetermined levels and warn of a pending overfill condition. Rack monitors using standard optic and thermistor signal formats communicate with the onboard monitor (overfill detection chassis) or directly to the “straight” optic or thermistor systems on the transport. This communication is accomplished via a pulsed, intrinsically safe electrical signal. The electrical signal is generated by the control monitor and is transmitted to the sensors through a coiled cord and industry standard plug. During normal operation, when the sensors on the trailer are dry and functioning properly, a signal is returned to the monitor. Providing this signal meets predetermined characteristics, the monitor goes to a “permissive” state. This “permissive” state provides a signal which changes the status lights on the front of the rack monitor (model number 8580), from a red to a green color, signaling to the terminal automation system (T.A.S) that everything is fine.
During the loading process, if a sensor becomes wetted, it sends a signal enabling the monitor to recognize the changed condition. Immediately, the status lights on the rack monitor (model number 8580) switch to red, a “non-permissive” state, and signals the terminal automation system (T.A.S.) for action (i.e. immediate shut-down). This system can be used for applications that include as many as twelve optic or eight thermistor liquid-level type sensors. The Model 8580 Opti-Therm Diagnostic Rack Monitor includes display status of the optic or thermistor, “permissive” or “nonpermissive” status and mode of operation.
