Starting up
4.2.2 What happens when powering up the transmitter
When the power is turned on, the transmitter takes several seconds to initialize. The display will
run through a set-up routine, first illuminating all display characters, and then showing the
software revision number. Finally, a full set of zeros is displayed while the microprocessor
identifies the correct return echo. After these checks are complete, the display indicates the live
measurement based upon the factory default values in memory.
When a new transmitter is aimed at a good target, the level reading is calculated using the
default value for the bottom reference.
On the Rosemount 3102 and Rosemount 3105, the duty chosen icon next to letter L (Level)
(and the RL2 icon on the 3102) will be illuminated. The RL1 icon on the 3102 may be
illuminated, depending on the level calculated by the transmitter at this time.
The transmitter is now ready to be programmed with details of the application. It may be
programmed on-site or prior to installation. All programmed data is retained in the transmitter
memory after the power is turned off.
4.2.3 Considerations before starting the programming
Important notes to help you program the transmitter
Do not allow rain or water to enter the transmitter during programming or the circuit
boards may be damaged.
The step-by-step instructions through is chapter show how to use the integral buttons
to navigate through the programming menu and select or enter application data.
Push the buttons firmly, but not too hard to avoid damaging the circuit boards. Also, to
avoid entering incorrect data, do not push the buttons too fast.
The 3102 and 3105 transmitters have a “load default values” routine that restores the
transmitter memory with factory default values. This will clear the memory of all
previous selected or entered data.
