3.1 Wiring
The installation of wiring should conform to all applicable codes. To
reduce the possibility of noise interfering with the control system,
exercise care when installing wiring from the system to external
devices. For detailed recommendations, refer to IEEE Standard 518
(Guide for the Installation of Electrical Equipment to Minimize
Electrical Noise Inputs to Controllers). For network cable installation
procedures, refer to the RĆNet Cable Installation Manual (J2Ć3009).
3.2 Initial Installation
Use the following procedure to install the module:
Step 1.
Stop any application tasks that may be running.
DANGER
THIS EQUIPMENT IS AT LINE VOLTAGE WHEN AĆC POWER IS CONNECTED,
DISCONNECT AND LOCK OUT ALL UNGROUNDED CONDUCTORS OF THE AĆC
POWER LINE. FAILURE TO OBSERVE THESE PRECAUTIONS COULD RESULT
IN SEVERE BODILY INJURY OR LOSS OF LIFE.
Step 2. Turn off power to the system. All power to the rack, as well
as all power to the wiring leading to the rack, should be
off.
Step 3. Take the module out of its shipping container. Take it out of
the antiĆstatic bag, being careful not to touch the
connectors on the back of the module.
Step 4. Insert the module into the desired slot in the rack. The
module can reside in any slot in an AutoMax/DCS5000
rack containing at least one Processor. Use a screwdriver
to secure the module into the rack.
Step 5. Set the drop number of the RĆNet module using the two
rotary switches on the module faceplate. The upper switch
is the most significant digit and the lower switch is the
least significant digit. The decimal node number value
must be converted to hexadecimal. Only settings 0 to 250
(0 to FA hexadecimal) are valid. Fault code 4 will be
displayed at powerĆup if the switches are set to a value
greater than 250. If the node number is less than 16
(decimal), the upper switch must be set to zero. Refer to
Appendix D for the node number conversion chart.
The node number settings are recognized only at
powerĆup. Therefore, make sure each node on the
network has a unique node number before power is
applied. If more than one device is given the same node
number, all of the devices having the same node number
will attempt to transmit at the same time resulting in line
transmission collisions and loss of data.
Step 6. Connect the Tee connector (M/N 45C70) to the BNC
connector on the face of the module.
Step 7. Connect the coaxial cable to the Tee connector. If this is
the last node on the network, place a 75 ohm terminating
load (M/N 45C71) on the remaining side of the Tee
connector.
