Configuration #2
- If your PLC I/O controls are located in a separate control room, a repeater is to be
mounted at the stock pile and the receiver is to be located at the control room
Repeater components:
1)
Repeater in NEMA 4 enclosure (Model 497-4500-120VAC)
2)
TNC “T” adapter, (Model 49
-5001)
3)
Two Coax cables with connectors (Model 49-4000-XX)
4)
Two Omni directional antennas with mounting hardware (Model 49-3101)
Locate a 120VAC source for powering the repeater.
Mount two omni antennas on the rail or floor of the cat walk. It is recommended to have the antennas mounted
on opposite corners of the cat walk, pointing
“down”, below the cat walk floor, at the dozer stock pile to get a
good 360-degree reception pattern around the stacking tube(s).
Attach coax cables to each antenna then connect to the repeater via the
“T” adapter which connects to the TNC
antenna connector on the side of the repeater.
Receiver components:
1)
16 relay receiver in a NEMA 4 enclosure (Model # 497-5280)
2)
Coax cable with connectors (Model 49-4000-XX)
3)
Omni directional antenna with mounting hardware (Model 49-3101)
The receiver is recommended to be located at the PLC I/O cabinet in the control room.
Locate a 120VAC power source for this receiver.
Mount the omni antenna on the outside of the plant, as high as possible so the antenna can
“see” the
antenna
from the repeater located at the stacker tube for maximum performance and range.
Attach coax cable to the antenna then connect to the TNC antenna connector on the side of the receiver.
Install control wiring from the relays in the receiver to the belt feeder control circuits. See product information
bulletin for relay output logic.
