Control and signaling device
CLOIS 3000
GAI-Tronics
Programmable Communication, Lock Out Indication and Signalling System
CLOIS 3000 is a flexible signalling and controlsystem 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. It 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.
