August 30, 2002 Manual Version 1.0 7.5
Section 7.4 Wiring
The wiring diagram for Programmable Limit Switch units is shown in Figure 7.3. 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. Wiring of PLS Outputs
Section 7.4.1 Wiring Input Power
Connection of AC input power is made to the 3 pin terminal block on the bottom right of the Model
5100-5 PLS/Logic Module. The pinout is provided on Figure 7.3.
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 7.4.2 Wiring High Speed Serial Bus Cable
The high speed serial bus cable is wired to the 4 pin terminal block on the bottom left of the Model
5100-5 PLS/Logic Module. The pinout is provided on Figure 7.3. 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 7.4.3 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 just above the high-speed serial bus terminal block. If this device
is the last device in the serial bus string, the termination switch must be placed in the closed (right)
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 (left) position. The red LED will be off when the switch is in the open position.
Section 7.4.4 Output Wiring
The wiring of the PLS output devices is shown in Figure 7.3.
