5 Information that potentially raises safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this to follow these installation guidelines could result in death orserious injury. Make sure only qualified personnel perform the could result in death or serious injury. Do not remove the connection head cover in explosive atmospheres when the circuit is live. Before connecting profibus devices in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-intrinsic field wiring practices. Verify that the operating atmosphere of the Transmitter is consistent with the appropriate hazardous locations certifications. All connection head covers must be fully engaged to meet explosion-proof leaks could result in death or serious injury. Do not remove the thermowell while in operation.

8 Device Revisions (NE53)CONSIDERATIONSG eneralElectrical Temperature sensors such as RTDs and thermocouples produce low-level signals proportional to their sensed Temperature . The 644 converts the low-level sensor signal to digital profibus PA signal that is relatively insensitive to lead length and electrical noise. This signal is then transmitted to the control room via two Transmitter can be commissioned before or after installation. It may be useful to commission it on the bench, before installation, to ensure proper operation and to become familiar with its functionality. Make sure the instruments in the loop are installed in accordance with intrinsically safe, FISCO, or non-incendive field wiring choosing an installation location and position, take into account the need for access to the MountingSpecial mounting hardware is available for mounting a 644 head mount Transmitter to a DIN rail, or assembling a new 644 head mount to an existing threaded sensor connection head (former option code L1).

9 Electrical Proper electrical installation is necessary to prevent errors due to sensor lead resistance and electrical noise. For best results, shielded cable should be used in electrically noisy environments. Make wiring connections through the cable entry in the side of the connection head. Be sure to provide adequate clearance for cover Transmitter electronics module is permanently sealed within the housing, resisting moisture and corrosive damage. Verify that the operating atmosphere of the Transmitter is consistent with the appropriate hazardous locations Effects The Transmitter will operate within specifications for ambient temperatures between 40 and 185 F ( 40 and 85 C). Heat from the process is transferred from the thermowell to the Transmitter housing. If the expected process Temperature is near or beyond specification limits, consider the use of additional thermowell lagging, and extension nipple, or a remote mounting configuration to isolate the Transmitter from the process.

Figure 1-1. 644 head mount Transmitter Connection Head Temperature Rise vs. Extension LengthExampleThe Transmitter specification limit is 85 C. If the ambient Temperature is 55 C and the process Temperature to be measured is 800 C, the maximum permissible connection head Temperature rise is the Transmitter specification limit minus the ambient Temperature (moves 85 to 55 C), or 30 this case, an extension of 100 mm meets this requirement, but 125 mm provides a margin of 8 C, thereby reducing any Temperature effects in the OF MATERIALSTo expedite the return process in North America, call the Emerson Process Management National Response Center toll-free at 800-654-7768.
