exTeRNAl SeT POINT WIRING

(eMS Input Terminals +, Signal, Shield)
• The Multi-MOD Platinum can be configured to accept a remote 4-20mA set
point from an Energy Management System (EMS) .
• Set the Multi-MOD Platinum EMS Input Mode to EMS-Control . See "EMS
Input Mode" on page 27 .
• There are two ways to wire the 4-20mA signal . The method used depends on
signal power source .
• If the EMS sources the voltage for the 4-20mA signal, connect the EMS signal
(+) to the Multi-MOD EMS SIGNAL terminal . Then connect the EMS signal (-)
to the Multi-MOD EMS SHIELD terminal . This is the most common method .
• If the Multi-MOD Platinum sources the current for the 4-20mA signal, connect
the EMS signal (+) to the Multi-MOD EMS + terminal . Then connect the EMS
signal (-) to the Multi-MOD EMS SIGNAL terminal .

CONNeCTING INTeRNeT COMMuNICATION

• Internet capable Multi-MOD Platinum controls are equipped with an Internet
communication board installed on the back of the main board .
• Connect the Ethernet cable coming from the Internet Modem or Internet
server to the RJ45 socket on the back of the communication board .
• See Platinum Internet Setup Manual for additional information on configuring
Internet controls and their features .

CONNeCTING BACNeT COMMuNICATION

• BACnet capable Multi-MOD Platinum controls has a BACnet communication
board that can communicate over BACnet IP or BACnet MSTP networks .
• When using BACnet IP, connect the BACnet CAT5 Ethernet cable coming
from the BACnet network to the BACnet RJ45 Communication socket
(Ethernet socket) on the Multi-MOD communication board .
• When using BACnet MSTP, connect the RS485 BACnet cable coming from
the BACnet network to the Black RS485 Communication socket on the
Multi-MOD communication board .
• Set the Multi-MOD BACnet Settings as described in the BACnet Manual .

CONNeCTING MODBuS COMMuNICATION

• MODBUS capable Multi-MOD Platinum controls has a MODBUS
communication board that can communicate over MODBUS RTU networks .
• Connect the RS485 BACnet cable coming from the MODBUS network to the
Black RS485 Communication socket on the Multi-MOD communication board .
• Set the Multi-MOD MODBUS Settings as described in the MODBUS Manual .
