Field installation of PLC I/O board:
1. Check header P2 on the controller board - straighten any bent pins.
2. Align the socket on the underside of the PLC I/O board with header P2 on the controller
board.
3. Push the PLC I/O board firmly onto header P2.
4. Secure the PLC I/O board to the standoffs with four #4-40, 1/4 inch long machine screws and
four #4 internal tooth star washers.
PLC wiring:
• Refer to the connection diagrams on page 121 for PLC wiring information.
Operation:
Note: Refer to page 21 for more information about setting controller parameters.
• The control inputs are either maintained or momentary, depending on the setting of
parameter 27.
In the maintained mode, deactivating all inputs will cause the actuator to stop.
In the momentary mode, deactivating all inputs will cause the system to remain in the last
valid operating mode. If the system is in Manual mode, deactivating all inputs will cause
the actuator to stop. The IN and OUT inputs must be maintained in order to move the
actuator.
• The function of the AUXILIARY, EDGE A, EDGE B, and LINE / CENTERLINE inputs
depends on the setting of parameter 51 and 52.
• The INHIBIT input overrides all PLC I/O inputs. To allow the PLC I/O inputs to operate
properly, the INHIBIT input must be inactive.
