NIVELCO SIGNAL PROCESSING UNITS - MULTICHANNEL PROCESS CONTROLLER - MultiCONT - 3

DIMENSIONS Without lockable cover With lockable, transparent cover A Pg9 / M16 B Pg11 / M20 Arrangement of mounting holes WIRING4-relay version MAINS Only for UNICONT modules. **Only for non-Ex versions. After loosening and removing screws fastening the cover the cables can be connected. The same cable should not be used for AC and DC as well as for SELV and mains voltage. For wiring of the transmitters shielded, twisted cable pair (STP) should be used with the l ength depending on the number of connected units and the electrical properties of cable.

NIVELCO SIGNAL PROCESSING UNITS - MULTICHANNEL PROCESS CONTROLLER - MultiCONT - 5

COMMUNICATION BET WEEN MultiCONT AND TR ANSMIT TERS Point-To-Point connection With using a master (MultiCONT) and one slave (transmitter) in a system, a point-to-point connection is established. Multipoint connection (Multidrop). Multiple slaves connected in parallel Using this type of connection, the current outputs of the transmitters are automatically set to 4 mA (multidrop mode, with address differing from zero). PROGR A MMING OF MultiCONT During programming the following operations can be performed: ■■ utomatic detection of devices (transmitters) connected to A the MultiCONT. ■■...

SYS T E M S E T- U P There is a Master-Slave relation between MultiCONT and the connected transmitters. MultiCONT queries the transmitters for their measured values and programs the transmitters remotely. In HART® multidrop mode when there are several transmitters connected to MultiCONT the transmitters have to be set to different polling addresses that differ from zero. This setting should be done one by one prior to the final wiring. In systems involving several MultiCONTs chained to one RS485 line all units have to have different polling addresses too. Wiring of 4-wire transmitters...
