Introduction
What is this Quick-start?
This Quick-Start is for anyone who has to install and commission the MSP-USTD1 or MSP-USTD2 ultrasonic system, and does
not need in-depth information.
For full installation instructions, you must refer to the installation (IM) manuals supplied with the equipment.
What are these MSP-USTD1 and MSP-USTD2 systems?
They are level, contents, or flow measurement and control systems. Suitable applications include wet well level (and pump)
control, tank contents measurement, and open channel flow measurement.
The system comprises mains or DC powered MCU901 control unit, an MSP900SH ultrasonic transmitter with a mounting kit,
and manuals. MSP-USTD1has the wall-mounted version of the MCU901; MSP-USTD2has the panel-mounted MCU901.

About the MCU901 Control Unit
The MCU901 unit is a member of the MCU900 family of control units. It has:
•Full support for a single MSP900SH ultrasonic transmitter – measuring level by default
•a 4-line LCD display with back light – displays both text and graphical information
•a 6 button keypad
•an LED indicator
•an intuitive menu system – for setting up
•2digital inputs (voltage-free contacts) for triggering various activities (e.g. displaying a message)
•5relay outputs (e.g. for controlling pumps, indicating alarms, etc.)
•a 4-20mA output.
All setting up is achieved from the front panel of the MCU901 control unit.
About the MSP900SH Ultrasonic Transmitter
This is a loop-powered transmitter, factory sealed and fitted with cable ready to install on aqueous applications. The transmitter
is pre-configured to measure liquid level and communicates values to the MCU901.

Installation
Location of MSP900SH
•Install the transmitter above the liquid surface using the bracket provided.
•Do not mount the MSP900SH on a structure that is subject to vibration, or in a position where damage may be caused by
impact or thermal stress.
•The equipment is not intended for use in areas exposed to dust.
•The equipment must not be installed directly in any process where the enclosure might be charged by the rapid flow of
non-conductive media.
Location of MCU901
•The MCU901 must not be located in a hazardous area. Do not mount the MCU901 where it is subject to vibration, or in a
position where damage may be caused by impact, thermal stress or liquid ingress.
•The MCU901W is housed in a tough IP65 enclosure. If mounted outside, it is recommended that the unit be protected from
direct heavy rain.
•The MCU901P is a standard DIN size designed for direct mounting in a control panel. It is designed for panel mounting in a
weatherproof environment.
Cabling (MCU901W)
1.Cable the MSP900SH to the MCU901 using the gland provided. (Undo 2 screws and lift cover away to reveal terminals).
2. Check the voltage selector switch (230V or 115V) and adjust if necessary. (Mains unit only).
3. Cable the power lead to the MCU901 using the gland provided. Do not apply power yet.
4. Make connections to relay terminals and current output terminals, if required.
5. Seal unused cable entries with the blanking plugs provided.
6. Replace and secure the terminal cover.
Cabling (MCU901P)
1. Cable the MSP900SH transmitter to terminals 1, 2and 3on the rear panel of the MCU901.
(See figure inset, right)
2. Check the voltage selector switch (230V or 115V) and adjust if necessary. (Mains unit only).
3. Cable the AC power supply to terminals 28 (Live) and 29 (Neutral) on the rear panel of the
MCU901. Note that mains Earth is not required. (Mains unit only).
4. Connect terminal 30 to an Intrinsically Safe Earth. This is essential only if the MSP900SH
is in located in a hazardous area.

Getting started
After completing the installation of both MCU901 control unit and the MSP900SH transmitter, the next stage is to switch on.
1.Familiarise yourself with the front panel fascia.
Front Panel Fascia of MCU901W
Key to figure:
c4-line LCD with backlight.
dKeypad with 6 function keys.
eStatus LED – flashes once per second if okay.
3. Familiarise yourself with the primary display.
Primary Display
Key to figure:
1. Off-line/on-line status. (Locked padlock = on-line)
(See page 14)
2. Digital input status. (o = de-energised, = energised)
3. Measured variable (P.V.) and units of measurement.
4. Bar graph of 4-20mA output of MCU901.
5. Relay (RL) status. (o = de-energised, = energised)
6. Digital communication in progress. (Absent if idle)
2. Switch on the MCU901 by applying the power. Wait
for the primary display (inset, right) to appear.
During this time, the MCU901 will read parameters
from the MSP900SH transmitter.
If being used for the first time, it will prompt for the
Bottom Reference of the MSP900SH transmitter
and then automatically set-up the 4-20mA output
span over this range. If you do not want to
commission the system now, simply switch off
the power – the same prompt will then re-appear
when switching on the next time.
If you are commissioning the system, edit the
Bottom Reference with the arrow-keys and then
press the yellow key to confirm the value. The
Bottom Reference can be changed at a later stage
but it is better to get it correct now. Should you
press the red (ESC) key, the MCU901 will continue
and the Bottom Reference prompt will re-appear
when switching on the next time.
Once the start-up is completed, the primary display
should appear, showing the measured depth of the
liquid in the tank. The value on the primary display
is the P.V. (Primary Variable).
Note: If a “Find Instrument” screen appears and
remains, power off. Check the cabling and then try
again. If the problem persists, follow the on-screen
prompts until the primary display appears.

How to display the menu system
4. Press the yellow (ENTER) key to display the top-level of
the menu system.
The primary display re-appears automatically if there is
no keypad activity for several minutes, if on-line. In
addition, it re-appears when pressing the ESC key
whilst at the top level of the menu system.
7. Programming the MCU901 unit is best achieved through easy-to-follow
Wizards. They are simply a sequence of on-screen prompts, allowing you
to easily set-up an individual function or a large application without fuss.
There is a collection of Wizards for most functions and applications. They
are all selected and started through the menu system. On the pages that
follow, examples for several applications show how to use them.
Example of a Wizard
8. Additional features, such as password protection, resetting to factory defaults, etc., can found on pages 14/15.
5. Navigation of the menu system is
achieved by using the ARROW
keys, the ENTER key, and the
ESC key. (See figure, right).
The ESC key will return you to
the
p
revious menu level.
Selecting this will bring up
the “Set-up” menu for
programming the MCU901.
Selecting this will bring up the
“Set-up” menu for optional
MSP900 programming.
The transmitter Bottom
Reference can be changed here.
6. The Main Menu sits above a series of sub-menus. Within the menus, there are
also parameter screens for programming – setting up for an application,
adjusting default settings, etc. – and for displaying information.
Selecting this will allow you
to monitor live readings and
diagnostic information for
the MCU901.
Direct access menu for
advanced users to select
parameter screens.
Toggles operating mode for
MCU901. An open padlock
indicates that the MCU901 is
off-line and parameter values
can be entered or changed.
(See page 14)
Selecting this will allow you to monitor live readings and
diagnostic information from the MSP900 transmitter.
