REVISION OVERVIEW
The following pages have been changed from the previous issue of this document:
page change
throughout All references to "M-Bus" and "Meter Bus" have been deleted.
ABOUT THIS USER GUIDE
This Excel 50 controller can be used in two different ways:
1. The Excel 50 controller can be used with embedded applications. Preconfigured
applications stored in memory in the application module are selected by
entering a specific code via its MMI or an external interface.
2. The Excel 50 controller can also be used with standard or custom applications
created with the CARE software package and downloaded into the controller.
Custom applications may have different screens and sequences than are shown
in this document. The screens shown here must be considered only as
examples.
Differences between these two uses of the Excel 50 are noted where appropriate.
NOTE: The format of the date is determined by the Engineering Units:
— US - mm/dd/yyyy
— Europe - dd.mm.yyyy
The start-up sequence is an exception to this: The date in the start-up
sequence must always be entered in the European format as shown above.

messages.
UP ARROW– Moves the cursor to the previous line.
DOWN ARROW– Moves the cursor to the next line.
RIGHT ARROW– Moves the cursor to the next field of the current line.
LEFT ARROW– Moves the cursor to the previous field of the current line.
PLUS – Increases a numerical value by 1 each time the key is pressed or switches a
digital status to the opposite status condition.
MINUS – Decreases a numerical value by 1 each time the key is pressed or
switches a digital status to the opposite status condition.
ENTER – Confirms any changes made or moves to the next screen.
Fast-access keys Function

›06:00 AH1_tsp 
NOTE: If the string "*****" should appear, this means that currently no value is
available.
The field name is sometimes shown in this User Guide to make a screen easier to
understand. Field names are not visible on the Excel 50 display.
NOTE: The screens shown in this User Guide are examples and may differ slightly
from the screens visible on your Excel 50 controller.

BASIC FUNCTION KEYS
LCD DISPLAY
FAST ACCES
S
KEYS
C
The 'Plant' procedure is used to choose the time program where changes should be
made to in the 'Time program' procedure and to make temporary changes to the
daily time program. The first screen of the 'Plant' procedure is the start screen. It is
the default screen and is always visible when no other screen has been selected.
This start screen will also be displayed if no key has been pressed for a long time.
The screen displays the name of the first time program, the application status, the
current day, the date, and the time. The next switching time of the first user address
of the time program with its current value/status is displayed below. Each time
program can be assigned to more than one user address. Each application can have
up to 20 different time programs.
The application status is shown in the upper right corner of the display and will
appear as one of the following:
Init Initializing—The application tasks are started, and data points and memory
are being initialized.
Run Running—All relevant application tasks are running.
Shut Shutdown—All relevant application tasks are halted. The application stops
step by step.
Stop Stopped—Some or all relevant application tasks are stopped. The application
does not run.
Press the 'Plant' fast-access key to display the default screen.

›TODAY ›NEXT
Using the arrow keys, move the cursor to
- 'NEXT' to display the next time program.
- 'TODAY' to make temporary changes to the current time program.
Confirm with ENTER.
If 'NEXT' has been selected, the screen will now display the next time program with
the switching point time of the first user address with its value/status and the current
day, date and time.

›TODAY ›NEXT
Like the previous screen, this next screen displays the next time program with its
switching point, value/status and current day, date, and time.
TODAY Function
The 'TODAY' function allows the user to make an immediate, temporary change to
the switching time point or the value/status without affecting the original time
program. When using the 'TODAY' function, the data point must have value/status
and start and stop times assigned.
Important
The new start time will be within 24 hours of the current time. That means
for example, that a start time of 10:00 a.m. entered at 10:27 a.m. will
activate the temporary changes the next morning. The changed fields are
valid for only 24 hours; they are automatically deleted after the stop time
has been reached.
If 'TODAY' has been selected, the screen will now display the password entry
screen.
Please Enter
