Section 6.4 Wiring
The wiring diagram for Model 5020 units is shown in Figure 6.2. The wiring diagram for Model 5121
units is shown in Figure 6.3. The following connections and operations must be done:
1. Input Power
2. High Speed Serial Bus Cable
3. Set High Speed Serial Bus Termination Switch
4. Module Number Selection
5. Sensor Connections
Section 6.4.1 Wiring Input Power
Connection of AC input power is made to the 3 pin terminal block on the bottom right of the circuit
board in the bottom of the enclosure. The pinout is provided on Figure 6.2 for Model 5120 or Figure
6.3 for Model 5121. This unit contains an input voltage selector. This selector allows for operation at
115 VAC or 230 VAC. The factory default is 115 VAC. If 230 VAC operation is required, the selector
must be switched to the 230 position. In addition, the input fuse must be changed from .5 amps to .25
amps. See specifications for fuse type.
The 3 pin plug supplied for connection of input power is a dual connector plug. As described in Section
2.1 and shown in Figure 2.3, this dual connector plug allows for input power to be strung from module
to module.
Section 6.4.2 Wiring High Speed Serial Bus Cable
The high speed serial bus cable is wired to the 4 pin terminal block on the bottom center of the circuit
board in the bottom of the enclosure. The pinout is provided on Figure 6.2 for Model 5120 and Figure
6.3 for Model 5121. The cable that is supplied by Link Systems for the high-speed serial bus that
interconnects the various components of the OmniLink II Press Automation Control must be used. This
cable must run from device to device without being spliced.
The 4 pin plug supplied for connection of the high speed serial bus is a dual connector plug. As
described in Section 2.1 and shown in Figure 2.3, this dual connector plug allows for the high speed
serial bus cable to be strung from module to module.
Section 6.4.3 Setting High Speed Serial Bus Terminal Switch
The high speed serial bus termination switch must be placed in the correct position. The high speed
serial bus termination switch is located on the top circuit board mounted on the door of the enclosure. If
this device is the last device in the serial bus string, the termination switch must be placed in the closed
(up) position. The red LED indicator next to the switch will light when the switch is in the closed
position. The last device in the serial bus string will have only one high speed serial bus connection to
the 4 pin dual plug. The last device will have a connection from the previous device, but will not
connect to any other devices. If this device is not the last device in the serial bus string, the termination
switch must be placed in the open (down) position. The red LED will be off when the switch is in the
open position.
