1.1 Getting Started
How to prepare the EDM 35 for use
For convenience you have a check list below to be sure that all prepara-
tions of the EDM are made before the application. Page references are
mentioned so you can easily find the point in question in this manual. If
the EDM is received in modules start at point 1, otherwise start at point 6.
1. Select all modules necessary for the appli-
cation.
2. Set jumpers on the input module and if used
also on the excitation output module and/or
the analogue output module.
3. Insert all modules according to the drawing
printed on the module:
• Power supply first (then from right to left).
• Mount blind covers in non-used slots.
4. Fill out the label on the main unit and the
shipping box with missing information (or-
dering key for system, power supply, input-
and output modules and ranges). Easy ac-
cess to this information might help you later.
5. Insert engineering unit in the front cover and
mount this.
6. The program needs information about the
actual input range. Check input range se-
lection and change if necessary.
7. Program panel meter to suit the application.

1.2 Overall Description
The EDM series 35 is based on a modular
concept consisting of a main unit and plug-in
modules. The concept provides the meter with
high flexibility and versatility. The offer of
input-, output- and power supply modules
makes it possible to configure the meter to
suit most applications.
Furthermore, the modular concept ensures
that the stock costs are minimized.
1.3 Features
The main features of the EDM series 35 are:
- Modularity
- Continuous measurement and monitoring of the analog signal of
the input variable
- Continuous monitoring of the measured value for exceeding the
programmed setpoint values
- Setpoints individually programmable: Value, hysteresis, high/low
alarm, time delay
- Separate programming of each output relay: energized/deener-
gized and status in overflow condition
- Additional software functions: scaling, data hold and peak/valley
- Input modules for measuring voltage (AC or DC), current (AC or
DC), resistance, temperature (Pt 100 or thermocouple J or K),
frequency or revolutions per minute
- Output modules with 1 or 2 relays or with analogue output (4 - 20 mA,
0 - 20 mA, 0 - 10 V)
- Power Supply modules for AC or DC supply as well as excitation
supply for sensor supply
- Interface to Carlo Gavazzi’s Dupline®Field and Installation Bus
The large variety of input signals of both electrical and industrial process
variables make the EDM an extremely versatile instrument suitable for
many applications.
The characteristics of the instrument are complemented by its easy
programming and configuration in accordance with the application.

2.1 Modules
2.1.1 Common description
The modules are parted into 3 categories: Power supply modules, input
modules and output modules. Each module is dedicated to its own
function or input variable.
To minimize the number of modules many input modules are designed
to cover all ranges. If you want to change the input range just press the
locking tabs and pull out the module to change a jumper position, rein-
stall the jumper and reprogram the range selection. If you change the
range from low to high level or vice versa it might be necessary for you
to use other terminal positions as well.
The input modules are available with terminals for program lock to
protect against unauthorized admittance.
All modules are easy to plug in - for your information the slot position is
marked on the drawing on the rear of the module.

2.1.2 Variants
2.1.2.1 Power Supply Modules
You will always need the power supply module. These are
available for the most common supply voltages. Due to the
size of the transformer the power supply module always
occupies 2 slots.
2.1.2.2 Input Modules
The input modules are divided into the following categories:
Voltmeters (AC or DC)
Ammeters (AC, DC or 10A AC/DC)
Ohmmeters
Thermometers (Pt 100, Thermocouple J or K)
Frequency - and Tachometers
Dupline®Analink Interface
For voltmeters, ammeters, ohmmeters, frequency - and tachometers
a jumper in the module determines the actual range for the module.
Switching from one range to another also means that you are switching
from one input circuit to another input circuit.
For ammeters 10 A AC/DC the jumper determines whether you are
measuring AC current or DC current. The thermometers do not include
a jumper - here the range is changed only through the programming.
For the Dupline®Analink interface module only the channel number has
to be coded on two rotary switches.
All input modules occupy 1 slot and they are always placed at left (rear
view of the main unit).

2.1.2.3 Output Modules
The output modules are divided into the following categories:
Relay output (1 or 2 relays)
Analogue output (4-20 mA, 0-20 mA and 0-10 V)
Excitation output (for sensor supply)
Depending upon the application you can choose between different out-
put types: An output module with 1 or 2 relays and/or an output module
with analogue output where you are able to select the required type of
analogue output with the jumpers. The relay output module is always
placed at right (rear view of the main unit).
With the excitation output module inserted you are able to supply for
example sensors which are a part of the application. With a jumper you
can select 12 or 24 VDC. This module shares slot #2 with the analogue
output module.

3.1 Procedure
Before the instrument is ready for use, i.e. before it is ready for the ap-
plication dependent programming, you have to prepare the instrument
physically (engineering unit, modules etc.) - this is described in chapter
3.2 Installation.
Before you are connecting the instrument to the mains or the power
supply you have to be sure that the right power supply module is used.
This is discussed in chapter 3.3 Rated Operational Voltage.
You have to check the jumper settings on some of the modules. The
range selected must be in accordance with your application. The
jumper setting is shown in chapter 3.4 Jumper Setting on Modules.
After you have set the jumpers the processing unit must know which
range you have selected. This “range code” has to be entered in the
software when the instrument is turned on. Further information will be
given to you in chapter 3.5 Input Range Selection.
3.2 Installation
First, if desired, you insert the engineering unit (3). You can choose a
unit from the set of engineering unit labels.
Then you mount the front
panel (2) on the instrument -
remember to seal with the enclosed
gasket (the largest of the two enclosed). Place the remaining gasket
round the body of the instrument and slide instrument into the panel
aperture. To optimize the tightness be sure that the panel cut-out is
completed and deburred. Be also aware that a too thin panel may
distort and not provide sufficiant sealing.
Fasten the instrument with the two brackets (1).

If you later want to replace the engineering unit (3), you insert a screw-
driver into the lateral slot in the front panel and turn (be careful!) the
screwdriver as shown until the front panel has been completely
removed. Replace the engineering unit.
You can find the panel cutout and the mechanical dimensions in chapter
7.3 Mechanical Dimensions.
3.3 Rated Operational Voltage
Before you switch on the instrument, make sure that the supply voltage
corresponds to the rated operational voltage indicated on the power
supply module.
3.4 Jumper Setting on Modules
As some modules are designed to cover several ranges it can be neces-
sary for you to select the required range by moving an internal jumper.
The major part of the input modules, the excitation output module and
the analogue output module have this possibility for range selection. On
the following pages the jumper setting is shown for the modules:
3.4.1 Voltmeters
3.4.2 Ammeters
3.4.3 Ohmmeters
3.4.4 Frequency - and tachometers
3.4.5 Dupline®Analink Interface module
3.4.6 Output modules
Note! Always remember to turn off the power supply before you plug in
or pull out the modules.

Rated operational voltage
Caution!!
Since the input circuitry is not galvanically
isolated, the potential of the measured
variable will be present on all connections
to the unit (i.e. “HOLD” input). This is im-
portant specially when you are measuring
line voltage and current.

3.4 Jumper Setting on Modules) you have to update or check the pro-
gramming to be sure that the programmed range code corresponds to
the range selected with the jumpers on the module. This is accom-
plished in calibration mode. Other functions in calibration mode are dis-
cussed in chapter 8.1 Calibration Mode. To change or check the pro-
grammed range follow the description below.
1. Press and simultaneously and switch on the unit. The
display shows . Release the keys. The display shows

4.2.1 Measurement and Control
In the measuring and control operating mode the instrument has the
following basic functions:
- Measurement of the input variable
- Display of the measured variable in the correct engineering unit
- Setpoint control with activation/deactivation of the alarm LED’s and
relays
- Detects when the input is out of range and indicating this with ±EE
in the display. The relay status will be as the preprogrammed fault
condition
- ‘Hold’ input detection
- Update of peak and valley function
- If analogue output module is present, repetition of the displayed
value in analogue form
The , and control the display. The normal function of
the display is to indicate the measured input variable.

The programming mode allows the user to define the instrument para-
meters:
- Password for access to programming
- Decimal point position
- Minimum and maximum values of the electrical input range
- Display span
and for each alarm setpoint:
- Setpoint
- High or low alarm levels
- Hysteresis
- Time delay
- Alarm relay normally energized/de-energized
- State of alarm relay in overflow conditions
Stepping from the programming of one parameter to the programming
of the next happens by pressing .
The normal measurement and control functions are not active in pro-
gramming mode. The alarm outputs are OFF. The analogue output is low.
