Milliamp output trim, milliamp output test, and frequency/pulse output
test procedures cannot be performed after security mode 8 is entered.
Before entering security mode 8,
perform milliamp trim and/or test
procedures, if necessary, as described in any of the following manuals or
in AMS on-line help:
•
Using the HART Communicator with Micro Motion Transmitters
•
Using ProLink Software with Micro Motion Transmitters
•
Using Modbus Protocol with Micro Motion Transmitters
To enter security mode 8:
1. Note the position of switch 5.
2. Set switch 10 to the ON position. The diagnostic LED on the
transmitter electronics module flashes on 3 times and pauses, which
indicates the transmitter is in the configuration mode.
3. Set switches 1, 2, and 3 to the ON position.
4. Set switches 4, 5, and 6 to the OFF position.
5. Locate the ZERO button on the transmitter electronics module.
6. Press and hold the ZERO button for five seconds. The diagnostic LED
will remain on for two to three seconds to indicate security mode 8
has been entered.
7. Reset switch 5 to the desired position (as noted in Step 1).
8. Reset switch 10 to the OFF (OPERATE) position. The diagnostic LED
flashes on once per second (25% on, 75% off), which indicates the
transmitter is in the normal operating mode.
9. Leave switches 1, 2, and 3 in the ON position to remain in security
mode 8.
To verify the transmitter is in security mode 8:
• If the transmitter has a display, use the Scroll knob to scroll through
process variable screens to event register screens. If event register
screens appear, the transmitter is in security mode 8. For more
information about using the Scroll knob and transmitter display, see
Section 6.2
, page 51.
• If the transmitter does not have a display:
1. Configure the transmitter.
2. Wait until the diagnostic LED blinks ON once per second.
3. Move switch 1, 2, or 3 to the OFF position.
4. If the diagnostic LED blinks ON 4 times per second, the transmitter
is in security mode 8.
