3.2.1 Types of actuators
Double-acting
This actuator actively opens and closes with activated drive motor. In the event of a power failure it
stops in the current position.
Single-acting, spring close
This actuator actively opens with activated drive motor. The closing procedure is carried out by spring
force. The actuator closes in the event of a power failure.
Single-acting, spring open
This actuator actively closes with activated drive motor. The opening procedure is carried out by
spring force. The actuator opens in the event of a power failure.
MOV, motor valve
This actuator behaves likes a double-acting actuator and contrary to this automatically turns the drive
motor off upon reaching the end position. The control module always leaves the current supply
switched on during normal operation.
Spring close, mechanical override with handwheel
This actuator corresponds to a normal spring-close actuator, but can be opened manually with the as-
sistance of a handwheel. This operating status is permitted and the control module will not report this
as an error. In order to re-close the manually opened actuator this must initially be completely opened
electrically. This function is carried out automatically by the control module.

spring close, electro-hydraulic override with hand pump and separate hand valve
The actuator operates like a standard spring close type but can manually be opened by means of a
manual operated valve and a hand pump. This operation mode is signalised at the CM3 module but is
not indicated as a fault. The actuator may be closed again by the CM3 by powering the magnetic
valve of the EHS. This will open the manual operated valve again.
spring close, hydraulic override with hand pump and separate hand valve
The actuator operates like a standard spring close type but can manually be opened by means of a
hand pump. Using the hand pump will open actuator and automatically prevent the oil from flowing
back to the tank. This operation mode is signalised at the CM3 module but is not indicated as a fault.
The actuator may be closed again manually by pressing a button or by the CM3 by starting the pump
for a few s.
double acting, Ex-Type
The Ex-type actuator can only be operated in combination with the capacitor module (9311222810).
The function equals a standard double acting actuator. This kind of actuator is available with
open/close and analog position indicator.
3.2.2 Operation modes of the actuators
Operation mode: open / close
After the drive command has been given, e.g. by pushing the command key in the direction of ”close“,
the actuator will operate until the final position is reached or the maximum permissible operating time
is exceeded. The alarm output is activated if the operating time is exceeded and alarm status signal-
ised via the light-emitting diodes on the module.
Operation mode: open / step closing
To a large extent this operation mode corresponds to the open/close operation mode. Upon closing,
however, the actuator is repeatedly stopped briefly in order to extend the closing time. In this connec-
tion the closing time is extended by the set operating time, i.e. the closing time is approximately dou-
bled. The turn-on times of the actuator amount to at least 1 second. Depending on the operating time
the actuator is halted up to 20 times.
Operation mode: step opening / step closing
To a large extent this operation mode corresponds to the open/close operation mode. Upon closing
and opening, however, the actuator is repeatedly stopped briefly in order to extend the closing or
opening time. In this connection the closing or opening time is extended by the set operating time. The
turn-on times of the actuator amount to at least 1 second. The actuator is halted up to 20 times.
Operation mode: %
In this operation mode the actuator is only operated for as long as the command key is depressed or
the command is pending. The actuator can thus be stopped in any position. Only exception: Insofar as
either of the actuator limit switches is operated, the actuator is moved to the appropriate end position
when the key is released. This ensures that the actuator has actually moved completely to the end po-
sition if this is signalised by the end position switch. For example, this function is used for throttle
valves.
Operation mode: %Pos
This operation mode is only used in connection with the issue of a command via a superimposed con-
trol system. In this case the superimposed control system prescribes the desired position of the valve
as a percentage and the control module automatically moves the valve into the target position. Devia-
tions from the target position not exceeding 2% are ignored by the module. This operation mode is al-
ways replaced by operation mode % during mimic diagram operation or local command input.

3.3 Adjusting the operating time
The operating time of the actuator can be adjusted by means of a potentiometer on the front side of
the module. The transparent module cover flap must be opened for this. In general a fairly rough ad-
justment (-5% .. +25%) is sufficient whereby, if anything, the time should be assessed somewhat too
generously.
The operating time should only be determined exactly for actuators with a successive opening or clos-
ing function and in particular for actuators with the %Pos operation mode. A help function is integrated
into the control software for this purpose, allowing this to be very simple and reliable.
In case of a %Pos operation mode the runtime setting determines when the actuator is stopped while
it is approaching the nominal position. If the actuator stops too early and does not reach the nominal
position please increase the runtime a bit. On the other hand, if the actuator overshoots the nominal
position please decrease the runtime.
3.3.1 Calibration of the operating time
• Set the operating time to maximum (r.h. limit stop).
• Move the actuator from the closed position to the open position by selecting the “local”
operation mode and pushing the command key in the direction of “open”.
• Once the actuator has opened completely, push the command key again in the direction of “open“
and hold depressed. Now slowly reduce the operating time until the red LED also starts blinking. If
both LED are blinking, the time has been adjusted correctly.
3.4 Extended operation modes
The function of the CM3 module can be changed by setting several extended operation modes. This
feature is implemented from Version V2.0 upwards. Up to four extended operation modes can be set:
1. mimic inputs are active even in local operation mode (V2.3 or higher)
2. mimic close input is inverted, that means it is activated if connected to 0V (V2.5 or higher)
3. mimic open input is inverted, that means it is activated if connected to 0V (V2.7 or higher)
4. the alarm contact indicates the position of the local remote switch,
closed = remote, open = local (V2.7 or higher)
One or more extended operation modes may be set concurrently.
If the Profibus is chosen during step 3, step 4 is not applicable.
Automatic baud rate setting is generally used for the Profibus protocol. When the last parameter is en-
tered the module changes to normal operation.
7.1.2 Setting the address of the EHS-CM3 / CCM modules
The address of the CM3 / CCM control modules is adjusted with the assistance of the CM3 / CCM
control elements. Those modules do not provide separate address switches. Operation mode change-
over on the CM3 / CCM module brings about the indication of the current module address on the
fieldbus interface for the duration of approx. 2 seconds.
As the address setting needs to be protected against unintentional alteration, it is necessary to
put the system in addressing mode. Addressing mode is set by pressing the “prgm” and “set”

keys on the BI simultaneously. This operation mode is shown as on the BI display. To leave this
mode just press both push buttons once more.
The CM3 / CCM module to be programmed is now switched to “remote“ operation mode. The
lowest available address on the local bus is now displayed by operating the command key in
any direction. An available address is an address to which no CM3 / CCM module will currently
respond. The two programming functions “delete“ and “accept“ are now available.
New modules are programmed in turn from left to right. Once programming has been completed the
fieldbus interface must be set to normal operation mode. For this both buttons are again pressed sim-
ultaneously.
PLEASE NOTE: The module address determines which register / data word is used by this actuator in
the data model of the fieldbus connection. If the address is not allocated as arranged, the wrong
valve will be activated. If possible, addressing should be carried out in such a way that the address
complies with the slot, i.e. that the 7th module, for example, is given address no. 7.
7.1.2.1 Deleting the module address
If the command key is pushed in the direction of “open“ and the operation mode is then switched to
local while the command key is depressed, the module address is erased. The module is then no
longer visible for the fieldbus interface.
7.1.2.2 Accepting the lowest available address
If the command key is pushed in the direction of “close“ and the operation mode is then switched to
local while the command key is depressed, the module address is set to the lowest available address.
This new address can be displayed again by changing the operation mode.
7.1.3 Setting the address and operation mode of the RK 16/8
The address of the RK16/8 control modules is adjusted with by means of the push button near the sta-
tus LED of the RK. If the button is pressed the module’s address is displayed at the BI. If the button is
pressed for more than 3s the module’s software version is displayed instead of the address.
As the address setting needs to be protected against unintentional alteration, it is necessary to
put the system in addressing mode. Addressing mode is set by pressing the “prgm” and “set”
keys on the BI simultaneously. This operation mode is shown as on the BI display. To leave
this mode just press both push buttons once more.
Now the push button of the appropriate RK must be pressed for some seconds. The status LED
first lights brightly and the turns off. The BI module now shows the lowest unused address for
an RK module in the range 61..80. As soon as the LED turns on again the button may be re-
leased. The RK is now programmed.
New modules are programmed in turn from left to right. Once programming has been completed the
fieldbus interface must be set to normal operation mode. For this both buttons are again pressed sim-
ultaneously.
PLEASE NOTE: The module address determines which register or data word in the data model of the
fieldbus connection to the BI is assigned to this RK. If the address is not allocated as arranged, the
wrong outputs are activated respectively the wrong inputs are read
Stetting the operation mode:
If the button is kept pressed after the LED turns on again for at least 2,5s the LED starts blinking. This
indicates the activation of the extended operation mode. In this case the state of each digital input is
hold for at least 0,9s. By this means even very short events can be detected securely. The version
changes from .x to .x if this operation mode is turned on (Version D.4 and higher).

7.1.3.1 Deleting the module address
To erase the module address the button must be pressed again. As soon as the LED turns off the but-
ton must be released. The module address is erased now and the module becomes invisible for the
BI.
7.1.4 Skipping addresses
If necessary an address gap may be inserted at an arbitrary position. If the BI module is in “set-up
mode” and the CM3 is set to “remote” operation, the lowest unused address is show when the close
button of the CM3 is pressed. Now the address may be increased by pressing the BI´s “Set” button or
decreased again by pressing the “Prgm” button. Only unused addresses are selected by the BI. This
set-up, that means the number of address gaps, is also used for further addressing of the CM3 mod-
ules until the BI´s “set-up mode” is left. (Remark: This function is only available for BI firmware version
V1.6 or higher).
Also addresses of the RK16/8 modules can be skipped. As soon as the lowest used address is shown
on the BI the “set” and “prgm” button can be used to modify the RK address.
7.1.5 Display functions
Various system data can be displayed for diagnosis purposes in connection with the “Set” and “Prgm”
keys of the fieldbus interface or the operation mode switches of the CM.
Display of the address of a CM3 module
Upon changing the operation mode (local – remote) of a CM3 its address is displayed for 2 sec-
onds via the 7 digit display of the BI (. = address 12).
Display of the lowest available address
The lowest available local address is displayed by pressing the set key of the fieldbus interface
(. = address 17). The address of the module in position 17 should be programmed as the
next CM3 module.
Display of modules that have failed
If a module does not respond to queries from the fieldbus interface for a certain period of time,
it moves to “offline“ status. The address of this module is then displayed for 3 seconds (.. =
address 13). The display of the address of the module that have last moved to offline status can
be repeated at any time by pressing the “prgm” key. Displaying .. indicates that none of the modules
have gone offline.
PLEASE NOTE: Only the change to offline status is registered. If a module never answers after
power up, it will not be displayed.
Display of control inputs 1 and 2
If control input 1 or 2 is set, or output will appear on the display.
Position indication of actuators with analog position feedback
If an actuator with analog position feedback is operated in „local“ mode the current position is dis-
played at the 7-segments display of the BI module. This indication is turned off a few seconds after
the actuator comes to a standstill. (Remark: This function is only available for BI firmware version V1.6
or higher).
Normal operation
If status display is not necessary, the display will switch to . (program execution).

7.1.6 Start messages and self test
Directly after the programme has started up, the module displays the last “reset“ cause in the form of
two digits. The module subsequently carries out a short self test. In the event that the self test is not
carried out successfully, the red LED will start to flash. If Profibus DP is selected as fieldbus the red
LED always indicates an error while the error code is shown in the display.
Once the self test has been carried out successfully the version number of the software (x.y) is dis-
played briefly. The normal status display begins subsequently (see above).
7.1.7 Power management
The BI module provides a power management function to limit the 230VAC supply current. To avoid
that the high starting current of the drives blows the fuses the actuators are started successively al-
ways one drive every 100ms. Additionally the number of running drives that are connected to the
same fuse is limited (default 8). The current that is required to keep the magnetic valve of a single act-
ing drive closed is neglected. A motor valve is treated like an EHS even though the current is much
less.
If more than 8 actuators of a group connected to the same fuse get a command, the execution of this
command is delayed in such a way that not more than 8 actuators are running simultaneously. Up to 4
of such groups can be configured for each BI. The first group begins with the drive using the address
1 and ends with address A1, the second groups begins with A1+1 and ends with A2 and so on.
The default set up uses 2 groups:
• group 1: drive 1..25
• group 2: drive 26..50
• number of drives: 8
7.1.7.1 Configuring the power management
To configure the power management the „Set“ button must be pressed for at least 3s while the BI
starts up. The display will now show . By pressing the “Set” button the group number can be in-
creased. Pressing the “Prgm” button will select this group and the last address of this group is shown
in the display. The “Set” button may now be used to increment the last address. The highest value is
50, the lowest value is the last address of the preceding group plus one. Pressing the “Prgm” button
once more will store the address and return to the group number display. If the last group (no 3) is
programmed or any group is programmed to address 50 the set-up is finished.
From BI V2.2 the number of drives running at the same time can also be adjusted. Instead of leaving
the set-up mode the number of drives is displayed in the lower digit while the upper digit shows a “.”.
The number can be changed using the “Set” button. Pressing the “Prgm” button will store the selected
number and leave the set-up mode.
PLEASE NOTE: The BI firmware secures that the last address of a succeeding group is always
higher than the last address of the preceding one. If this condition is not fulfilled the
firmware will adjust the addresses automatically.

7.1.8 Set-up of Quick Close Functions
The control input E2 of the BI module is used to activate differ-ent quick close functions. As soon as the input is set a close or open command is sent to all CM3 modules that are appropri-ately parameterised. This parameterisation is done in the set-up mode of the BI module. At first the appropriate CM3 is se-lected by changing its operation mode. Afterwards the “Prgm” push-button is pressed. The present mode is now displayed.
By pressing the „Set“ push-button the required mode is se-
lected and confirmed by pressing the “Prgm” push-button once more. The mode that is valid at pre-
sent is displayed with the decimal points turned on otherwise the decimal points are turned off.
This function must be repeated for all required CM3. Press both push-buttons simultaneously to leave
the set-up mode.
7.1.9 Alarm output
To begin with the alarm output is closed after the self test has been carried out successfully. Cyclical
testing is carried out subsequently as to whether the modules connected to the local bus are working
accurately. If a module is not available (offline) or if a CM3 / CCM module reports a fault (e.g. timeout)
or is set to local operation mode, the alarm output will be opened and not closed until the fault has
been removed and the alarm acknowledged on the CM3 module.
7.1.10 Lamp test
Terminal no. 3 on the local bus is used as a lamp test input. As soon as 24V are applied, the 3 LED
and all segments of the 7-segment display of the module are illuminated.
7.1.11 Bus Termination
If the BI module is placed at a physical end of the bus the bus cable has to be termi-
nated. This can be done by means of a miniature switch at the front of the module. If
both sliders are set to ON position the termination is turned on, if they are set to the op-
posite position the termination is turned off. All other settings are not allowed.
The bus termination is an active one and meets the Profibus standard.

8 BI Modbus interface (slave) The Modbus interface of the fieldbus interface serves to exchange data with a superimposed control
and visualisation system, hereinafter referred to as Modbus master. A register in both report direction
and control direction is used for every valve. Transmission is carried out via an RS485 connection.
The baud rate (4800-76800 baud), the parity (none, even, odd) and the Modbus address (1h..6Fh) can
be parameterised. The number off data bit is fixed to 8. One stop bit is used.
The fieldbus interface has a Modbus RTU interface (slave) and serves the following functions:
• 03 Read holding registers
• 06 Preset single register
• 16 Set multiple registers
This chapter describes the applied data model, i.e. the use and meaning of the individual registers of
the Modbus. This information is required for the preparation of the data model of the superimposed
control system and for the commissioning of the Modbus interface as the case may be. More detailed
information about the Modbus protocol may be obtained from www.modbus.org.
8.1 Modbus data model
The data model described here complies with the program version 1.5 or higher.
The first register is always used to monitor the fieldbus interface itself. The following registers are
used for the CM3 and the IO modules.
In detail, the binary digits of the registers have the following meaning:
8.1.1 Fieldbus interface BI status, register 1, (read only)
Bit Meaning
Bit0 CM3 fault, collective message
Bit1 IO fault, collective message
Bit2 reserved
Bit3 control input E1 set
Bit4 control input E2 set
Bit5 control input „lamp test“ set
Bit6 running in passive mode (see also: 10 !used only if secondary BI is connected)
Bit7 RK16/8 fault, collective message
Bit8..14 not used
Bit15 live bit, changes state every 2s *
*implemented in BI version V1.6 or higher
CM3 fault collective message
This binary digit is set if at least one EHS-CM3 reports a fault.
IO fault collective message
This binary digit is set if at least one IO module reports a fault.
Fault on the local data bus
This binary digit is set if at least one module on the local bus replies to broadcast address 0 or if fur-
ther faults arise that cannot be allocated to a specific bus participant.
Control input E1 / E2 set
This binary digit is set if control input E1 / E2 has been set (24V).
Control input lamp test set
This binary digit is set if lamp test input has been set.
