3. After applying power, the control unit searches for a HART transmitter.
A HART transmitter with the factory default polling address of 0 is found after 15
seconds. The control unit automatically changes the Transmitter Poll Address from
“0” to “1” and it is designated "Tx1" (Transmitter 1) and assigned to Channel 1.
The control unit reads parameters from the HART transmitter and makes them
available for local interrogation and programming within the menu system.
4. When an unconfigured Rosemount 3100 Series Level Transmitter is being used for
the first time, a prompt appears asking for the Transmitter [1] Bottom Reference.
Do one of the following:
•
If commissioning the system now, edit and save a new Transmitter Bottom
Reference or keep the existing Transmitter Bottom Reference. After the start-up
process is complete, the display appears showing a measurement e.g. liquid
level or the menu system.
•
If the system is not to be commissioned at this time, simply switch off the power
and the same prompt re-appears when switching on the power next time. The
Transmitter Bottom Reference can be changed later, but it is better to get it
correct now.
Need help?
If the
Re-connecting to Digital Transmitter
message does not appear,
check that the operating mode of the control unit is set to
Run App mode
and that
the Input Channel Source is set for a digital HART input.
5.
Turn the power supply off and connect the second HART transmitter, such that
both HART transmitters are connected at the same time.
6. Turn the power supply on.
7. The control unit searches for, and detects, the two connected HART transmitters.
After the second HART transmitter is found, the control unit automatically changes
the Transmitter Poll Address from “0” to “2” and it is designated "Tx2" (Transmitter
2) and assigned to Channel 2.
The control unit reads parameters from the HART transmitter and makes them
available for local interrogation and programming within the menu system.
8. When a unconfigured Rosemount 3100 Series Level Transmitter is being used for
the first time, a prompt appears asking for the Transmitter (2) Bottom Reference.
Do one of the following:
•
If commissioning the system now, edit and save a new Transmitter Bottom
Reference or keep the existing Transmitter Bottom Reference. After the start-up
process is complete, the display appears showing a measurement e.g. liquid
level or the menu system.
•
If the system is not to be commissioned at this time, simply switch off the power
and the same prompt re-appears when switching on the power next time. The
Transmitter Bottom Reference can be changed later, but it is better to get it
correct now.
The two HART transmitters are now known to the control unit, and will be
remembered each time the power is switched off and on.
