Functional description
The instrument is a modularly designed
indicator/controller for use in both simple and
demanding control tasks. It can be integrated
into the PLC via interfaces
To make programming and operation easy, all
parameters are clearly assigned to levels and
displayed in plain text. Operation is protected
by a code word. Operation can be adapted on
an individual basis because parameters can
be generally enabled or assigned to the
protected area.
A setup program for the PC is available as a
more convenient configuration option, rather
than using the instrument keypad.
User data
Up to 8 parameters that are frequently
changed by the user can be combined in the
user level under "User data" (via setup
program only).
Displays and controls
(1) Binary outputs (relays)
Output active if symbol is visible.
(2) Binary input
Input closed if symbol is visible.
(3) Keyboard inhibit
Keys locked if symbol is visible.
(4) Alarm message
ALARM (flashing): Broken sensor or
overrange, etc.
AL R1: Controller monitoring alarm
from controller channel 1.
AL R1: Controller monitoring alarm
from controller channel 2.
CALIB: Calibration mode active.
CALIB (flashing): Calibration timer
elapsed.
(5) Output mode
MAN.: Manual mode active.
HOLD: Hold mode active.
(6) Top display
Measured value and unit of the
variable set by parameter "Top
display".

Display modes
The following display modes are available:
Normal display
In this display method the measurements
appear in numbers, as usual.
Large display
This method uses the complete display
height.
Tendency display
In this display a symbol is added to the
numerical value to indicate the direction and
speed of change for the measurement value.
This can be very useful for optimizing the
controller, for example.
From left to right:
Fast, medium and slow rise, steady,
slow, medium and fast fall.
Bar graph
In this display mode, it only takes a glance to
ascertain the range for the current
measurement.
Any scale can be used for the bar graph.
Tendency curve (data monitor)
The ring buffer contains about 100 measuring
points. The sampling and storage rates can
be adjusted.
(7) Bottom display
Measured value and unit of the
variable set by parameter "Bottom
display".
(8) Operating mode
MEASURING: Standard measuring
mode is active.
Boards
PSU board (1)
This board is always fitted in the instrument
and no variations are possible.
The board includes the following items:
• The voltage supply for the
JUMO dTRANS CR 02.
• The voltage supply for external 2-wire
transmitters.
• 2 relays with changeover contacts.
Main board (2)
This board can not be changed subsequently!
The main board (CR) has:
• The main input for connecting a two- or
four-electrode conductivity cell.
• The secondary input for connecting a
temperature sensor Pt100, Pt1000, a
resistance transmitter or a standard signal
0(4) to 20 mA or 0 to 10 V.
• 2 binary inputs.
• The setup interface (for PC interface
adapter).
Optional board (1), (2) or (3)
These boards are combinable and can be
ordered in the following versions:
• 1 analog input
• 1 continuous output
• 1 relay (changeover)
• 2 relays (NO with common pin)
•1 Triac (1A)
•1 PhotoMOS
®
relay (0.2 A)
The following boards can only be placed in
slot 3, either:
• Modbus/Jbus
• PROFIBUS-DP
• Datalogger
For versions with a wall-mounted case the
(re)placement of the optional boards by the
customer is not possible.
