The 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 8480, 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 closes a set of relay contacts which changes the status
lights on the front of the rack monitor (model number 8480)
switch to red, a "non-permissive" state, and signals
the termination automation system (T.A.S.) for action (i.e.
immediate shut-down). This system can be used for applications
that include as many as eight optic or thermistor liquid-level
type sensors.
The model 8480,
Opti-Therm Diagnostic Rack Monitor included display status of
the opitc or thermistor "permissive" or "non-permissive"
status mode of operation.
