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.

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.

Other Features
Restoring factory defaults (Erases all user entered data)
To re-set the MCU901 unit back to the factory defaults, navigate to the “Load Defaults” screen and press the ENTER key twice.
Navigating to the LOAD DEFAULTS Screen
PIN Security
Personal Identification Number (PIN) security prevents unauthorised people from programming the MCU901 control unit.
Typically, this is set-up when all the other programming has been completed. As with Bankcards, there is one PIN number.
The factory default is for PIN security to be inactive. To activate, navigate the menu system to the PIN screen and edit a 4-digit
personal identification number (PIN) that you want. The PIN is edited with the arrow keys and confirmed with the ENTER key;
the 4-digit PIN will then be replaced by “- - - -“ to indicate that PIN security is active. (By default, PIN is a 0 if inactive).
Once PIN security is activated, a prompt for the PIN will appear when needed for an activity, such as starting a Wizard. If
correctly entered, no further PIN requests are made unless the “Cancel Password” option is selected from the MAIN MENU
screen. This menu option appears only after correctly entering the PIN; the option disappears when selected, therefore making
the MCU901 secure and prompt for the PIN when needed.
Navigating to the PIN set-up screen
Modes of operation
There are two operating modes for the MCU901. They are on-line and off-line.
An open padlock icon indicates the MCU901 is presently in the off-line mode. In this mode, the unit can be
programmed providing that you know the security PIN (if set-up). Additionally, the 4-20mA output and all relays
are frozen.
A closed padlock icon indicates that the MCU901 is presently in the on-line mode. In this mode, most of the unit
cannot be programmed. However, you will be prompted to go off-line if you attempt to programme whilst in this
mode and providing that you know the security PIN (if set-up). Additionally, the 4-20mA output and all relays are
not frozen.

January 2006 (IP2040/QS)15
Relays
Relay outputs 1 to 4 are normally On Point/Off Point relays which may be used to start/stop pumps or open/close valves at
different levels. They normally energise at one level and de-energise at a different level.
Alternatively, they may be programmed as out-of-limits alarms such that they are energised between defined points and will de-
energise outside the defined limits. They may also be programmed to perform a variety of auto-sequences and auxiliary
functions, such as pump-down operations, pump rotations to equalise wear, and desludge/cleaning.
Relay output 5 is normally a fail safe fault relay but may be re-allocated to another duty.
Relays can be set-up easily using the Relay Wizard, accessible by navigating to the RELAYS menu screen.
Navigating to the RELAY Screen
Relay (RL) Status
The relay status icons on the primary display have the following meanings:
= energised Relay is presently energised.
0 = de-energised Relay is presently de-energised.
A = Alarm All active alarms can be viewed by parameter D831.
S = Sampler Relay is allocated to sampling duty.
T = Totalising Relay is allocated to totalising duty.
Comfort (System) Settings
The SETTINGS menu allows adjusting of the time and date, switching off the keyboard sound and changing language.
