OVERVIEW

Power Up

Before Programming

The Mobrey MSP422 ultrasonic level transmitter is operated from a menu of parameters, each held in a specific memory location within the transmitter. The memory locations may be pictured as a matrix, and navigated for programming the instrument using ↓ and → steps.

The Integral Display Menu structure is shown in Figure 4-1 on page 4-3.

The transmitter is pre-programmed at the factory with a value in each parameter location so that when the power is first applied, the transmitter gives a sensible reading.

This section details the local programming using the push-buttons provided inside the transmitter.

When the power is turned on, the transmitter takes several seconds to initialize. The display will run 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.

On a new instrument aimed at a good target, the transmitter calculates a level reading based upon the default value for the bottom reference.

The transmitter is now ready to be set-up with details of the application.

The transmitter may be programmed prior to, or after, installation. All programmed data is retained in the transmitter memory after the power is turned off.

Important notes to help you program the transmitter:

a)Do not allow rain, or water, to enter the transmitter during programming or the circuit boards may be damaged.

b)See the instructions below on how to use the push-buttons to navigate through the programming menu and select or enter application data.

c)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.

d)Holding down the green button ↓ scrolls through any option list.

e)Pressing the red button ↵ at certain locations in the menu returns you to the previous level in the menu (see Figure 4-1 on page 4-3).

Note, however, if the red button ↵ is pressed after a menu option selection has been made or new data has been entered (i.e. stopped flashing), this option selection / new data will automatically be saved (see Figure 4-1).
