Sistemi s.r.l.
FLOTEL solves all problems concerning local management, supporting the logistic services with special functions of remote monitoring, through phone network. Without accessories or auxiliary devices, FLOTEL performs following functions : • • • • •
status and measurements local monitoring operative and clinical alarms local monitoring measurements, status and alarms remote monitoring switch over system data management on local network
FLOTEL set-up in field is inexpensive and does not require qualified operators, thanks to modular architecture and local network interface, standard supplied. FLOTEL chassis is a IP65 plastic box, used for wall mounting.
Programming All programming functions are easily performed by four push-button on front panel. A large display 20 charters x 4 lines operates as user interface and monitoring element.
Alarms local monitoring All digital or analog inputs can generate alarm status. Programming functions allow to enable or disable each alarm status related to a digital input, and to associate two alarm threshold (low and high) for each analog input. Specific messages on the display (set by user), alarm lamps blinking and electronic buzzer indicate an alarm status ; buzzer can be turned off by an acknowledge push-button, placed on front panel. Auditory signals and visual indications of alarm status can be set by user to technical or clinical operative standard following the UNI ISO 7396-1 and UNI ISO 60601-1-8. Moreover the units satisfies the essential basic safety requirements of the European Directive 93/42/CE concerning medical devices. With reference to Annex IX – Rule IX of same directive, the above mentioned devices are Medical Devices in class IIb within the limits of following intended purpose: I) alarm monitoring for central storage of medical gases and their primary distribution lines, in combination with electrical contact sensors and / or measuring transducers with 4 ... 20mA output as required by ISO 7396-1 Med certificate issued by the notified body n ° 047 6 These performances make FLOTEL a good solution for alarms monitoring in industrial and medical applications.

Measurements and status local monitoring FLOTEL manages 4 analog inputs for 4...20 mA transmitters and 10 digital inputs for switch sensors. Measurements are showed on the display directly in standard units, with relative identification string and standard unit identifier. Programming operations allow user to set range of transmitter, standard unit, identification string for any inputs; moreover, if input must monitor a gaseous storage, also medium, deadweight and capacity of cylinder / bundle can be set. Concerning digital inputs, programming include switch operation NO / NC and an identification string for each input.
Remote monitoring An optional modem card enables data transmission through phone network between FLOTEL and the telemetric mainframe. Remote link includes sending alarms and updates from FLOTEL to mainframe, real time programming and inquiring from mainframe to FLOTEL. The exclusive performances of modem allows to share phone line between FLOTEL and whichever phone device (as popular phone, fax, standard modem, etc.), without causing interference between users or limiting phone functions.
Sending alarms Alarms status associated to FLOTEL inputs, above mentioned, can be transmitted to telemetric mainframe in real time, by modem.
After alarm receiving, mainframe can send alarm specifications in vocal syntheses to technical operators, by phone.
Remote monitoring During real time connection from mainframe to FLOTEL, user can know actual values of measurement, digital inputs and alarms status. If some input was associated to compressed storages, software application of mainframe will supply a forecast planning, constantly updated, about ending of each storage. Forecasts are calculated from statistic of time steps between next minimum level alarms (for analog and digital inputs) and corrected by effective level measurements, periodically sent from FLOTEL units (only for analog inputs).

Switch over system Using optional module MCR4, for bundle management, FLOTEL goes an innovative electronic switch over system. Only one FLOTEL unit can be configured to switch over system for two bundle pairs or enabling back-up cylinders of four separate bundles. Automatic switch over functions can be transferred in manual, to keyboard on front panel, or to telemetric mainframe, by modem.
Example of switch over system with two banks controlled by weight scales.
Information collecting Local network interface, standard supplied, allows connection up to 32 units FLOTEL, CRIOTEL and MIXTEL, to easy collect and manage all information concerning the same building. Modular lay-out always guarantee a inexpensive and easy monitoring network, also regarding big or complex installations including gas storage in cylinders, cryogenic tanks, mixers and other equipment. Thanks to local network, an entire installation can be monitored in the same time from remote, by only one modem card and only one phone line, and in local, by a Personal Computer at customer, minimizing electric installations and without accessories. Local network connection between units and local personal computer occurs with a little shielded cable, length of which can reach some kilometers.
