ROC364 Instruction Manual 1.4 Installation Guidelines The design of the ROC makes it highly adaptable to a wide variety of installations; therefore, not all possibilities can be covered in this manual. If additional information is required concerning a specific installation, contact your local sales representative. Planning is essential to a good installation.
ROC364 Instruction Manual 1.4.1 Environmental Requirements The ROC364 requires protection from direct exposure to rain, snow, ice, blowing dust or debris, and corrosive atmospheres. If the ROC is installed outside of a building, it must be placed in a NEMA 3 or higher rated enclosure to ensure the necessary level of protection. NOTE: In salt spray environments, it is especially important to ensure that the enclosure is sealed properly, including all entry and exit points.
ROC364 Instruction Manual 3. Group defines the hazardous material in the surrounding atmosphere and include: ♦ ♦ ♦ ♦ Group A – Atmosphere containing acetylene. Group B – Atmosphere containing hydrogen, gases, or vapors of equivalent nature. Group C – Atmosphere containing ethylene, gases, or vapors of equivalent nature. Group D – Atmosphere containing propane, gases, or vapors of equivalent nature.
ROC364 Instruction Manual Proper grounding of the ROC helps to reduce the effects of electrical noise on unit operation and helps protect against lightning. Lightning Protection Modules are available to provide additional lightning protection for field wiring inputs and outputs. Refer to Appendix A for information about lightning protection. A surge protection device installed at the service disconnect on line-powered systems also offers lightning and power surge protection for the installed equipment.
ROC364 Instruction Manual For an analog I/O channel, the Duty Cycle is approximated by estimating the percentage of time the channel spends in the upper half of its range (span) of operation. For example, if an Analog Input wired as a current loop (4 to 20 milliamps) device operates in the upper half of its range 75% of the time, then 0.75 would be used as the Duty Cycle. If the analog channel generally operates around the midpoint of its span, use 0.5 as the Duty Cycle. 2.

ROC364 Instruction Manual STATIC SENSITIVE DOC0034C Figure 3-1. Typical I/O Module 3.2.1 Analog Input Loop and Differential Modules The Analog Input Loop (AI Loop) and Analog Input Differential (AI Differential) modules are used for monitoring current loop and voltage output devices. Each AI module uses a scaling resistor for scaling loop current to achieve the proper input voltage.
ROC364 Instruction Manual 3.2.4 Discrete Input Source and Isolated Modules The Discrete Input Source (DI Source) and Discrete Input Isolated (DI Isolated) modules monitor the status of relays, solid-state switches, or other two-state devices. Each module can accommodate one DI. Both types of modules provide an LED that lights when the input is active. Both types of modules use a scaling resistor for scaling the input range.
ROC364 Instruction Manual 3.2.8 Slow Pulse Input Source and Isolated Modules The Slow Pulse Input Source (SPI Source) and Slow Pulse Input Isolated (SPI Isolated) modules count the changes in the status of relays, solid-state switches, or other two-state devices. Each module can accommodate one Pulse Input. The modules provide an LED that lights when the input is active. Both types of modules use a scaling resistor for scaling the input range. Functions supported are controlled by the ROC firmware.
ROC364 Instruction Manual 3.3 Initial Installation and Setup Each I/O module installs in the ROC in the same manner. Any I/O module can be installed into any I/O module socket. To install a module on a ROC that is not in service, perform the following steps. For an in-service ROC, refer to Section 3.5, Troubleshooting and Repair, on page 3-21.
ROC364 Instruction Manual 3.4.1 Analog Input Loop Module The Analog Input Loop module monitors either loop current or output voltage from field devices. The module provides source power at terminal A for the loop. The AI Loop module operates by measuring the voltage at terminals B and C. For current loop monitoring, scaling resistor R1 generates a voltage across terminals B and C that is proportional to the loop current (I). A 250-ohms scaling resistor (R1) is supplied by the factory (0.
ROC364 Instruction Manual 3.4.2 Analog Input Differential Module A schematic representation of the field wiring connections to the input circuit of the Analog Input Differential module is shown in Figure 3-4, Figure 3-5, and Figure 3-6. The Analog Input Differential module measures either output voltage (Vo) or loop current (I) from externally-powered devices only. The module operates by measuring the voltage between field wiring terminals B and C.
ROC364 Instruction Manual For current loop devices, scaling resistor R1 generates a voltage across terminals B and C that is proportional to the loop current. When connecting current loop devices, the value of R1 must be selected such that the 5-volts input limit of the module is not exceeded under maximum operating current conditions. For 0 to 20 milliamps or 4 to 20 milliamps devices, the value of R1 would be 250 ohms. In this case, you can use the 250-ohms (0.
ROC364 Instruction Manual For example, a 250-ohms scaling resistor would accommodate either 0 to 20 milliamps, or 4 to 20 milliamps current loop transmitters (the transmitter must be able to operate on 10 volts dc or be powered from another source). This translates to a maximum operating input voltage of 5 volts dc, which is the upper limit of the module.

ROC364 Instruction Manual 3.4.6 Discrete Input Isolated Module A schematic representation of the field wiring connections to the input circuit of the Discrete Input Isolated module displays in Figure 3-12. NOTE: The Discrete Input Isolated module is designed to operate only with discrete devices having their own power source, such as “wet” relay contacts or two-state devices providing an output voltage. The module is inoperative with non-powered devices.
ROC364 Instruction Manual When using the Discrete Output Source module to drive an inductive load, such as a relay coil, a suppression diode should be placed across the input terminals to the load. This protects the module from the reverse Electro-Motive Force (EMF) spike generated when the inductive load is switched off.

NOTE: The Discrete Output Relay module is designed to operate only with discrete devices having their own power source. The module will be inoperative with non-powered devices. The Discrete Output Relay module operates by providing both normally-closed and normally-open contacts to a field device.
ROC364 Instruction Manual A 10-ohms scaling resistor (R1) is supplied by the factory and accommodates a source voltage (Vs) of 11 to 30 volts dc and a pulse source with a 50% Duty Cycle. The source voltage is the input voltage to the ROC. However, it is desirable to optimize the value of R1 to reduce the current drain from the source or reduce the heat generated in the module due to high source voltage. The formula for determining the value of R1 is given in Figure 3-16.

The field wiring connects through a separate terminal block that plugs in next to the module allowing replacement of the module without disconnecting field wiring. NOTE: The Low-Level Pulse Input module is designed to operate only with pulse-generating devices having their own power source.
ROC364 Instruction Manual NOTE: The RTD module input can be calibrated before installing it in the field when short wire WHT C A B C WHT B 1 RED A RTD runs will be used, but if the RTD module is used as a temperature input to a flow calculation, then the RTD should be calibrated at the same time as the pressure inputs.

ROC364 Instruction Manual 3.4.15.2 Connecting RTD Module Field Wiring The RTD sensor connects to the RTD module with ordinary copper wire. To avoid a loss in accuracy, sensor wires should be equal in length, of the same material, and the same gauge. To avoid possible damage to the RTD module from induced voltages, sensor wires should be kept as short as possible. This is typically 3.35 meters (100 feet) or less.
ROC364 Instruction Manual RTDs with four wires normally have the compensation loop separate from the active element loop to increase the accuracy of the probe. Various colors are used for the probe wires. For example, some probes have wire colors of red and white for the RTD element loop and black leads for the compensation loop, while other probes use two red leads for the active element loop and two white leads for the compensation loop.

ROC364 Instruction Manual 3.5.12 RTD Input Module The RTD module is similar in operation to an AI module and uses the same troubleshooting and repair procedures. The RTD module can accommodate two-wire, three-wire, or four-wire RTDs. If two-wire RTDs are used, terminals B and C must be connected together.
ROC364 Instruction Manual 3.5.13.2 Verify HART Communications Equipment Required: Dual-trace Oscilloscope In this test, the HART module and the ROC act as the host and transmit a polling request to each HART device. When polled, the HART device responds. Use the oscilloscope to observe the activity on the two HART communication channels. There is normally one second from the start of one request to the start of the next request. 1.
ROC364 Instruction Manual For example, if you have AI modules installed in slots A7, A10, and A11, adding another AI module in slot A8 changes the point numbers of the Analog Inputs for modules in slots A10 and A11. If one or more FSTs, or higher level points, such as a PID loop or AGA Flow, have been configured in the ROC, be sure to reconfigure them according to the changes in I/O modules. Operational problems will occur if you do not reconfigure the ROC. 3.6.
