□
If possible, install the transmitter in a location that will prevent direct exposure to sunlight. The environmental limits for the transmitter may be further restricted by hazardous area approvals.
□
If you plan to mount the transmitter in a hazardous area:
WARNING
— Verify that the transmitter has the appropriate hazardous area approval. Each transmitter has a hazardous area approval tag attached to the transmitter housing.
— Ensure that any cable used between the transmitter and the sensor meets the hazardous area requirements.
— For ATEX/IECEx installations, strictly adhere to the safety instructions documented in the ATEX/IECEx approvals documentation available on the product documentation DVD shipped with the product or at Emerson.com
.
□
Verify that you have the appropriate cable and required cable installation parts for your installation. For wiring between the transmitter and sensor, verify the maximum cable length does not exceed 1,000 ft (305 m).
□
Ensure that you use the following cables for the different connections:
— A certified PROFIBUS-PA cable for PROFIBUS-PA terminals
— A shielded, twisted-pair instrument cable with drain for all output connections
□
You can mount the transmitter in any orientation as long as the conduit openings do not point upward.
Installing the transmitter with the conduit openings facing upward risks condensation moisture entering the transmitter housing, which could damage the transmitter.
Following are examples of possible orientations for the transmitter.
Preferred orientation Alternate orientations
Installation Manual
□
Any fittings, adapters, or blanking elements used on either conduit entries or threaded joints that are a part of flame proof joints must comply with the requirements of EN/IEC
60079-1 & 60079-14 or CSA C22.2 No 30 & UL 1203 for Europe/International and North

Only qualified personnel can select and install these elements in accordance with
EN/IEC 60079-14 for ATEX/IECEx or to NEC/CEC for North America.
□
To maintain the Ingress protection thread sealant, a sealing washer, or O-ring must be applied:
— For Zone 1 applications thread sealant must also comply with the requirements of
EN/IEC 60079-14 and thus must be non-setting, non-metallic, non-combustible, and maintain earthing between the equipment and conduit.
— For Class I, Groups A, B, C, and D applications thread sealant must also comply with the requirements of UL 1203/CSA C22.2 No. 30.
□
Mount the meter in a location and orientation that satisfies the following conditions:
— Allows sufficient clearance to open the transmitter housing cover. Install with 8 in
(203 mm) to 10 in (254 mm) clearance at the wiring access points.
— Provides clear access for installing cabling to the transmitter.
— Provides clear access to all wiring terminals for troubleshooting.
Additional considerations for retrofitting existing installations
□
The transmitter installation may require 3 in (76 mm) to 6 in (152 mm) of additional wiring for the input/output and power connections. This length would be in addition to the currently installed wiring. Confirm you have the additional wiring necessary for the new installation.
□
Before removing the existing transmitter, be sure to record the configuration data for the currently installed transmitter. At initial startup of the newly installed transmitter, you will be prompted to configure the meter via a guided setup.

Setting the 5700 for PROFIBUS-PA communication
Addressing
Set the 5700 address using either of the following methods:
• Locally using rotary switches
• From the software using ProLink III, the display, or from the class 2 PROFIBUS-PA host using the Set_Slave_Add command
Set the 5700 PROFIBUS-PA using rotary switches
You can use the three rotary switches on the back side of the 5700 display circuit board to assign the transmitter a PROFIBUS-PA hardware address.
The valid hardware address range is 0 to 125. Setting the rotary switches to ≥ 126 sets the software address.
• SW1 = hundreds
• SW2 = tens
• SW3 = ones

Example
If the SW1:SW2:SW3 switches are set to 0, 2, and 5 respectively, then the 5700 address is
(0 x 100) + (2 x 10) + (5 x 1) = 25.
Hardware addressing considerations
• The 5700 needs to power cycle in order to read the new hardware address.
• A hardware address ≥ 126 is an invalid address and the 5700 goes into software addressing.
• If the hardware address shifts from an invalid address (≥126) to a valid hardware address (≤125), the 5700 will accept the hardware address, irrespective of the software address setting.
• If the hardware address shifts from a valid address (≤125) to an invalid hardware address (≥126), the 5700 will stay at address 126 until the software addressing changes the address.

Set the 5700 software address using any of the following methods:
• From the display
• From ProLink III
• From the class 2 PROFIBUS-PA host using the Set_Slave_Add command
You can set the 5700 address using the display or ProLink III only if the hardware rotary switches are > 125. If the 5700 address is changed using ProLink III or the display, the 5700 starts communicating on the new address with a PROFIBUS-PA host after a power cycle.

Power up the transmitter
October 2022
Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks or for process measurement.
Procedure
1.
WARNING
If the transmitter is in a hazardous area, do not remove the housing cover while the transmitter is powered up. Failure to follow these instructions can cause an explosion resulting in injury or death.
Ensure that all transmitter and sensor covers and seals are closed.
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. The transmitter is self-switching and will automatically detect the supply voltage. When using DC power, a minimum of 1.5 amps of startup current is required. During this period,
Alert 009 is active. The diagnostic routines should complete in approximately
30 seconds. The status LED will turn green and begin to flash when the startup diagnostics are complete. If the status LED exhibits different behavior, an alert is active.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to ten minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power has been off long enough to allow components to reach ambient temperature, allow the electronics to warm up for approximately ten minutes before relying on process measurements. During this warm-up period, you may observe minor measurement instability or inaccuracy.

Using the display controls
October 2022
Using the display controls
The transmitter display interface includes a display (LCD panel) and four optical switches – left, up, down, and right arrow keys – used to access the display menus and navigate the display screens.
Procedure
1. To activate an optical switch, block the light by holding your thumb or finger in front of the opening.
You can activate the optical switch through the lens. Do not remove the transmitter housing cover.
Important
The transmitter only detects one switch selection at a time. Be sure to place your thumb or finger directly over a single optical switch, and ensure no other switches are being obstructed.
Figure 9-1: Proper finger positioning for activating an optical switch
Installation Manual
2. Use the arrow indicators on the display screen to identify which optical switch to use to navigate the screen (see examples 1 and 2).
Important
When using the arrow keys, you must first activate the optical switch then release the same switch by removing your finger from the glass to move up, down, right, left or to make a selection. To enable auto-scroll when navigating up or down, activate the appropriate switch and continue to hold for one second. Release the switch when the desired selection is highlighted.
