EN-214 Emerson Motion Control Digital Servo Drive

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.

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.
