GAI-Tronics Mining CLOIS 3000 Programmable Communication, Lock Out Indication and Signalling System Solus Pullkey CLOIS 3000 BMA Tail End Unit Cadlock Lock-out • A user programmable signalling and control system utilising 4 conductors for both signals and communications • Up to 25 intrinsically safe loudspeaker amplifiers • Non-handed self identifying keys • Up to 127 individually monitored and identified unit positions • Remote telemetry RS232/485 interface • Applicable to all types of conveyors, rope haulages and other plant CLOIS 3000 is a flexible signalling and control system for conveyors, haulages and other plant. The system console comprises an intrinsically safe enclosure which houses the microprocessor controlled signalling circuitry and a telemetry interface. A Power supply and Pilot relays are housed in a separate flp or XP enclosure. In addition to the console a system can include remote amplifiers (BMAs), and various types of lock-out and signal keys as shown in the block diagram on the reverse of this data sheet. A Tail End Unit terminates the system cable. The system is extremely flexible and may be used as a control system in mines and tunnels for all types of conveyors and haulages. The system provides tone signalling, emergency trip, loudspeaker communications and two monitored pre-start alarms. The standard system provides transducer monitoring facilities for up to eight line-proved digital inputs. In addition to the pilot outputs, the console has facilities for up to four intrinsically safe relay outputs and one analogue output for unit position indication. System status is broadcast with voice synthesised messages whenever a status change takes place.
