FX-490 Emerson Motion Control

The system operates from 120 V AC or 220 V AC, 50/60 Hz single-phase power with

internal three wire power terminals. Ensure that a good safety ground is provided to the

electrical supply to which the power input is connected. The system contains three main fuses

(6.3x32 mm, 1 A) in the DIN-rail mounted fuse blocks. Each chassis and the LCD touch panel

are independently fused. Each NIM is powered from redundant 24 V DC power supplies from

the two chassis power supplies. The LCD touch panel is powered from an independent 24 V DC

power supply. All other modules within the unit are powered over the base back plane from the

associated main chassis power supply.

Field Network Wiring

The field network is wired in a ring configuration from Port A around a loop to Port B of the

network master. Beginning at Port A, the network is wired to Port A of the first actuator and

then from Port B of the first actuator to Port A of the second actuator and so on until the

network returns from Port B of the last actuator to Port B of the network master. Networks

may have parallel wired (bus wired) actuators between series wired actuators. Always wire

parallel actuators to Port A and remove termination and bias. Do not connect more than 15

actuators in parallel between any two series connected actuators. Networks are polarized with

(+) and (-) symbols on all drawings. Proper operation requires that polarity be observed at all

connections. Connect the field networks to the Port A and B connectors on the NIM in the

network master as shown in Figure 9. The networks must be connected to Port A and Port B

of the valve actuators as shown in the wiring diagram of the XTE3000/ICON3000 IOM. Others

320B and RTS, please refer to their IOM for network wiring diagram. Controlinc 320B Quick

Start manual. Controlinc supports many different network topologies. This manual supports

only a single ring E>Net network topology that allows a combination of parallel (bus) and series

E>Net connections on the same network.
