Introduction
The electronic unit builds the interface between
the actuator and the control
system.
During continuous positioning, the electronic unit
varies the motor torque continuously until the
actuator force and the control valve force are
balanced.
High response sensitivity and high positioning
accuracy with short positioning time ensure a
n
excellent control quality and a long actuator life.

… 2 Design and function
Principle of operation
The electronic unit builds the interface between the actuator and
the control system.
During continuous positioning, the electronic unit varies the
motor torque continuously until the actuator force and the
control valve force are balanced. High response sensitivity and
high positioning accuracy with short positioning time ensure an
excellent control quality and a long actuator life.
Electronic units are available for assembly in the field near the
actuator, remotely in a mounting rack or for integrated assembly
(smallest actuator type). In addition to the terminals, the
electronic unit contains the microprocessor, frequency converter
for motor control, analog and binary inputs and outputs,
PROFIBUS® or HART® communication interfaces, the
commissioning and service field and a plug connection to
connect a PC.
No matter what the motor power of the respective actuator is,
all electronic units are supplied single-phase by 230 V or 115 V
mains supply (50 Hz or 60 Hz).
The commissioning and service field enables the end positions
and direction of rotation to be set on the actuator. Moreover,
status information is displayed using LEDs. Push buttons can be
used to operate the actuator and set the operating mode
(Automatic, Out of Service).

All claims for damages must be submitted to the shipper
without delay and before installation.
Transporting the device
Safety instructions
DANGER
Danger to life due to falling or toppling loads.
Risk of death or serious injury due to the device falling down
or toppling over!
• Standing under suspended loads is prohibited.
• Do not detach the hoisting equipment until installation is
complete.
• Only use the dedicated load pick-up devices (eyebolts) for
suspending the components.
Consider the following items during transport:
• Pay attention to the device weight details.
• Do not expose the device to humidity during transport.
Pack the device accordingly.
• Pay attention to the permissible transportation
temperatures for the device.
Returning devices
For the return of devices, follow the instructions in Repair on
page 38.
Storing the device
The electronic units EAS822, EBS852, EBS862 comply with IP

If, for technical reasons, the load-bearing eyelet cannot be used,
the two halves of the housing can be installed separately.
Separating the housing halves
1. Place the electronic unit on a horizontal surface.
2. Unscrew the cover screws (Figure 2).
3. Flip open the electronic unit cover.
4. Disconnect the internal plug connection between the housing
halves.
5. Close the electronic unit cover.
6. Unscrew the hinge screw (Figure 2).
7. Flip the electronic unit cover forward while lifting it up and
off the hinge pin. Precisely guide the cover of the electronic
unit cover in the process.
Mounting
1. Fasten the electronic unit or the lower part of the electronic
unit to the vertical mounting rail of the mounting rack using
grade 8.8 screws. Tensile strength 800 N/mm2
(116032 pounds/square in.), yield strength 640 N/mm2
(92826 pounds/square in.).
2. Provide adequate room for installation and ensure easy
access.
3. The cable entries must be directed down.
Mounting the housing halves
1. Set the electronic unit cover down on the hinge pin and screw
in the hinge screw. Precisely guide the cover of the electronic
unit cover in the process.
2. Reconnect the internal plug connection.
3. Close the electronic unit cover and screw in the cover screws
(Figure 2 on page 5).

Safety instructions
WARNING
Risk of injury due to live parts!
When the housing is open, contact protection is not provided
and EMC protection is limited.
• Before opening the housing, switch off the power supply.
WARNING
Danger due to electric current!
Danger of electric shock by residual voltage at the terminals
after switching off the power supply.
• Before opening the terminal compartment, switch off the
power supply and wait for > 2 minutes.
NOTICE
Damage to the device due to improper handling!
• When replacing the defective safety fuses, only fuses with
types and characteristics should be used (see Fuses on
page 39).
The electrical connection may only be established by authorized
specialist personnel.
Notices on electrical connection in this instruction must be
observed; otherwise, electric safety and the IP-rating may be
adversely affected.
Safe isolation of electric circuits which are dangerous if touched
is only guaranteed when the connected devices fulfill the
requirements of EN 61140 (basic requirements for secure
separation).
To ensure safe isolation, install supply lines so that they are
separate from electrical circuits which are dangerous if touched,
or implement additional isolation measures for them.
Each actuator requires a suited Contrac electronic unit with
installed actuator-specific software. Observe the information in
the operating instruction. The specifications on the name plates
of the electronic unit and actuator must match to guarantee
correct hardware and software allocation.
Instructions on the use of Error Current
Circuit Breakers (RCDs)
If additional protection against accidental contact due to the
use of an RCD is required by local regulations, the following
items should be observed:
• For the electronic unit EBS822, the use of a type B RCD is
not necessary, since from a design viewpoint, no voltage
levels > 60 V DC which can be dangerous upon contact
can occur.
• The use of a Type B RCD is recommended for the
electronic units EBS852 and EBS862.
• The operator is responsible for the correct layout of
additional protection against accidental contact due to
the use of an RCD!

Selection of suited connection cables
Please observe the following information when selecting cables:
• Use shielded cables for the motor/brake cable, the
sensor cable, and the signal cable to the control
system/controller.
• Connect the shielding of the motor/brake cable and the
sensor cable on both sides (to the actuator and to the
Contrac electronic unit).
Potential equalization
In order to avoid the risk of an electric shock, it must not be
possible to come into contact with dangerous live parts and
conductive parts that can be touched should not become
dangerous live parts either under standard conditions or under
conditions when a single fault occurs.
The actual current flowing in the event of a fault is obtained
from the phase to ground voltage and the total impedance
present in the fault circuit.
For long cables, the voltage drop may be dangerous to come
into contact with high current flowing.
Preferably, the electronic unit and the actuator must be
connected with low resistance (ground resistance < 0.1 Ω) to the
potential equalization.
In the process, the respective standards of the VDE 100 series
must be observed.

Scenario 1
If the PE of the actuator is done only via the PE conductor of the
motor cable, the maximum permissible cable lengths for the
electronic units EAS822 and EBS852 are reduced in accordance
with the following table.
The maximum permissible shutdown time of 200 ms in case of a
fault is complied with in the process.

Scenario 2
By laying an extra potential equalization conductor between the
electronic unit and the actuator, with a small conductor cross-
section of the motor cable (e.g. 1.5 mm2), the maximum
permissible cable length can be increased.
The ground resistance of the potential equalization conductor
must be < 0.1 Ω.
The maximum permissible shutdown time of 200 ms in case of a
fault is complied with in the process.

Scenario 3
If the cable lengths specified in Actuator assignment and
maximum cable lengths on page 20 are fully utilized, an
additional protective potential equalization must be connected.
To do this, the electronic unit and the actuator must be
connected via a short cable with a minimum cross-section of
4 mm2(12 AWG) to the on-site potential equalization.
The installation regulations for setting up grounding systems
must be observed and followed.
