4.1 Overview
Mobrey MSP400RH and MSP900GH ultrasonic liquid level transmitters are 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 Appendix C: Integrated Display Menus.
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. Default values are
listed in Appendix D: Mobrey MCU900 Series.
The MSP400RH and MSP900GH are HART-enabled, allowing remote communications with the
instrument. The transmitter can be programmed using a suitable HART-compatible master, or
locally using the push-buttons provided inside the transmitter.
Note
This section details the local programming. Refer to Appendix F: Configuring Using
HART if using a Mobrey MCU900 Series control unit or a Field Communicator.
4.1.1 Display and push-buttons
The integral display allows up to five characters. In running mode, the Primary Value (PV)
measurement is displayed. In programming mode, data is displayed to assist with
programming.
To the left of the main display are four arrow icons; one will be illuminated to indicate the
selected duty.
To the right of the PV display on The MSP400RH are two arrow icons that indicate the status of
the transmitter relays. When illuminated, they indicate the relay contact is closed.
Under the PV display is a text string indicating the units of measurement. The transmitter will
illuminate only those characters applicable to the units of measurement chosen.
To the right of the text string is an echo received icon. It is made up of three arc segments that
continuously indicate the strength of the echo received (minimum, average, and good).
