Figure 6. Mounted on a Vertical Pipe Aluminum/Plastic Junction Box Stainless Steel Junction Box STEP 2: WIRE AND APPLY POWER Bus power is polarity insensitive, allowing the user to connect positive (+) or negative (–) screw terminals to either Fieldbus wiring terminal labeled “Bus.” I/O power terminals are polarity sensitive and proper connection must be made to avoid damaging the unit. Using Cable Glands 1. Unscrew the four cover screws to remove the junction box cover. 2. Run the sensor and power/signal wires through the appropriate cable glands using the pre-installed cable glands. 3. Install the discrete I/O wires into the correct screw terminals. 4. Install the power/signal wires onto the correct screw terminals. 5. Replace the enclosure cover and tighten all cover screws. 4696 Rev AB4x6_print.fm Page 6 Thursday, September 30, 2004 10:38 AM Quick Installation Guide 00825-0100-4696, Rev AB October 2004 Rosemount 848L STEP 2 CONTINUED... Using Conduit Entries 1. Unscrew the four cover screws to remove the junction box cover. 2. Remove the five conduit plugs. Install the user-supplied conduit fittings. 3. Run pairs of discrete I/O wires through each conduit fitting. 4. Install the discrete I/O wires into the correct screw terminals. 5. Install the power/signal wires into the correct screw terminals. 6. Replace the enclosure cover and tighten all cover screws.

Integrated Power Conditioner and Filter 6234 ft (1900 m) max (depending upon cable characteristics) Terminators (Trunk) (Spur) (Spur) Power Supply Signal Wiring FOUNDATION fieldbus Host or configuration tool Devices 1 through 16* STEP 3: VERIFY TRANSMITTER CONFIGURATION Each Foundation fieldbus host or configuration tool has a different way of displaying and performing configurations. Some use Device Descriptions (DD) or DD methods for configuration and to display data consistently across platforms. There is no requirement that a host or configuration tool support these features. The following is the minimum configuration requirement for a measurement. This guide is designed for systems not using DD methods. For a complete list of parameters and configuration information refer to the Rosemount 848L Reference Manual (document number 00809-0100-4697). 4696 Rev AB4x6_print.fm Page 9 Thursday, September 30, 2004 10:38 AM Quick Installation Guide 00825-0100-4696, Rev AB October 2004 Rosemount 848L STEP 3 CONTINUED... I/O Transducer Block The 848L is ordered with either Dry Contact, VDC or NAMUR Inputs. Each input can have a filter which determines the minimum time a contact needs to be at a given state to be acknowledged as a state change. The following procedure allows the sensors to be configured: 1. Set MODE_BLK.TARGET to OOS 2. For each Input “n” select the parameter IN_n_CONFIG.FILTER a. Select the desired filter time in the range of 0 to 128msec 3. Set MODE_BLK.TARGET to AUTO Resource Block The resource block defines the physical resources of the device, such as measurement and memory. The resource block also handles functionality that is common across multiple blocks. The block has no linkable inputs or outputs, and it performs memory-level diagnostics. Digital Input Blocks The DI blocks are used to communicate the current value of a contact, the state of one of the Boolean equations, or the state of an output. The DI block chooses the value through the Channel parameter. Alternatively, the DI block can be configured to pass 8 values in a packed format to the host system (DeltaV) by using the appropriate channels. To set the channel number use the following procedure for each DI block. 1. Set MODE_BLK.TARGET to OOS 2. Select the Channel parameter 3. Select the desired channel number 4. Set MODE_BLK.TARGET to AUTO 4696 Rev AB4x6_print.fm Page 10 Thursday, September 30, 2004 10:38 AM Quick Installation Guide 00825-0100-4696, Rev AB October 2004 Rosemount 848L STEP 3 CONTINUED... Digital Output Blocks The digital output blocks are used to receive a value from another device to be used to either drive a contact output or to use in the logic equations. The DO blocks make their values available to the 848L by placing the value in a variable called DO (n) where n=1 to 4. Like the DI block, all four outputs can be communicated in a packed format by selecting the appropriate channel number. Logic Transducer Block Logic Equations The 848L provides for 16 Logic Equations and 4 Output Equations. The Output Equations drive the hardware outputs. Each logic equation consists of up to 80 characters with the last character a semicolon. The equations are evaluated a nominal rate of 100msec. However this will vary based on the number and complexity of the equations used. The logic block consists of variables that are connected to the hardware I/O, obtain values or send values over the bus and internally calculated variables. 4696 Rev AB4x6_print.fm Page 11 Thursday, September 30, 2004 10:38 AM Quick Installation Guide 00825-0100-4696, Rev AB October 2004 Rosemount 848L PRODUCT CERTIFICATIONS Approved Manufacturing Locations Rosemount Inc. — Chanhassen, Minnesota USA Emerson Process Management Asia Pacific Private Limited — Singapore Rosemount Temperature GmbH - Karlstein, Germany European Directive Information The EC declaration of conformity for all applicable European directives for this product can be found on the Rosemount website at www.rosemount.com.
