Configuring your AMETEK Eclipse 706 Magnetrol transmitter correctly is essential for accurate level sensing. You can configure it using the local display, a HART-compatible handheld terminal, or a computer with PACTware and the appropriate DTM. Here's a simplified guide:
- Preparation: Gather the necessary tools. You might need open-end or adjustable wrenches, a torque wrench (optional but recommended), a flat-blade screwdriver, a cable cutter, and a digital multimeter or volt/ammeter.
- Parameter Access: Navigate the configuration parameters on the transmitter. Key settings to consider include:
- DIELECTRIC: Set this to "Below 1.7" for propane and butane, or "1.7–3.0" for typical hydrocarbons.
- FAULT: Avoid setting this to "HOLD", as it won't signal faults on the current loop.
- BLOCKING DISTANCE: This must be set to Zero for SIL applications; consult the factory before changing.
- LOOP CONTROL MODE: Ensure this is set to "ENABLED".
- THRESHOLD: Set to "FIXED" if used in hydrocarbon applications that may have water bottoms.
- PASSWORD: Change the default password (0) to a custom value to prevent accidental changes.
- Protection: Write-protect or lock your configuration. The Model 706 uses a numerical password (0-99,999). It's best practice to set a password after configuration.
- Testing: Perform a site acceptance test after installing and configuring the transmitter to ensure everything works correctly. This test follows the Proof Test Procedure described in the manual.
- Documentation: Keep a record of the site acceptance test results for future reference. For more detailed instructions and specific recommendations for your setup, consult the AMETEK Eclipse Model 706 Magnetrol User Manual (Bulletin 57-606).
