2.2 Electrical work •Electrical work must be carried out by a qualified electrician.
•Before commencing work, disconnect the product from the
mains and safeguard it from being switched on again.
•Observe applicable local regulations when connecting to the
mains power supply.
•Adhere to the requirements of the local energy supply com-
pany.
•Earth the product.
•Observe technical information.
•Replace a defective connection cable immediately.
2.3 Functional safety Note the following if the pump is operated within explosive en-
vironments:
•Install dry-running protection and connect using an Ex-i evalu-
ation relay.
•Connect level sensor via a Zener barrier.
•Connect thermal motor monitoring using Ex-certified evalu-
ation relay. It is possible to retrofit the "MCB112" PTC thermis-
tor card in the frequency converter for a connection to the
Wilo-EFC!
•In connection with a frequency converter, connect dry-running
protection and thermal motor monitoring to the Safe Torque
Off (STO).
SIL level
Provide safety equipment with SIL-Level 1 and hardware fault
tolerance 0 (according to DINEN50495, category 2). Consider all
components within the safety circuit for system assessment.
Refer to the individual components' manufacturer’s instructions
for the required information.
Ex rating sensor CLP01
•The built-in capacitive sensor CLP01 is type-tested separately
according to guideline 2014/34/EU.

en
6 Installation and operating instructions • Wilo DDI-I • Ed.03/2023-06
•The sensor also meets the requirements according to IECEx on
the basis of the prototype test.
2.4 Data security All network requirements, in particular network security require-
ments, must be complied with to integrate the product into the
network. For this purpose, buyers or operators must comply with
all valid, national and international directives (e.g. Kritis Directive)
or statutory stipulations.
2.5 Emergency operation in
applications critical to
safety
The pump and frequency converter are controlled by the para-
meters input at the corresponding device. The pump also over-
writes the frequency converter's parameter set 1 in LPI and LSI
mode. We recommend creating a backup of corresponding con-
figurations and saving them in a central location to guarantee fast
troubleshooting.
NOTICE!It is possible to save a further configuration in the fre-
quency converter in applications critical to safety. In the event
of a fault, the frequency converter can be operated in emer-
gency operation using this configuration.
3 Product description
3.1 Structure The Digital Data Interface is a communication module with integrated web server that has
been integrated in the motor. It is accessed and controlled in an Internet browser using a
graphical user interface. The user interface enables easy pump configuration, control and
monitoring. Different sensors may have been installed in the pump for this purpose. Ex-
ternal signal transmitters may also input additional system parameters in the control. The
Digital Data Interface is capable of the following, depending on the system mode:
•Pump monitoring.
•Controlling the pump with a frequency converter.
•Controlling the complete system with up to four pumps.
3.2 System modes The Digital Data Interface can be licensed for three different system modes:
•DDI system mode
System mode with no control function. Only temperature and vibration sensor values are
recorded, evaluated and saved. The pump and the frequency converter (if present) are
controlled via the operator’s primary control.
•LPI system mode
System mode with control function for frequency converters and clogging detection.
The pump/frequency converter pairing works as a unit: the frequency converter is con-
trolled through the pump. This allows clogging detection to be carried out and, if neces-
sary, a cleaning process to be started. Level-dependent control of the pump takes place
via the operator’s primary control.
•LSI system mode
System mode for complete control of the pumping station with up to four pumps. In this
process, one pump operates as the master and all other pumps are slaves. The master
pump controls all other pumps depending on the system-specific parameters.
Licence keys enable system mode. System modes with less comprehensive functional
scopes are included.

3.5 I/O modules – additional inputs
and outputs
A host of measuring data is required to control the pump/frequency converter combination
(LPI system mode) or the complete system (LSI system mode). Usually the frequency con-
verter provides a sufficient number of analogue and digital inputs and outputs. If required,
inputs and outputs can be supplemented by two I/O modules:
•Wilo IO1 (ET-7060): 6x Digital inputs and outputs
•Wilo IO2 (ET-7002): 3x Analogue and 6x digital inputs, 3x digital outputs
NOTICE
Wilo IO2 for LSI system mode is mandatory!
Include Wilo IO2 (ET-7002) in system planning to record all required
measured values! System control is not possible without Wilo IO2.
4 Electrical connection DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death
due to electric shock!
• Electrical work must be carried out by a qualified electrician!
• Observe local regulations!
DANGER

•Wire 2: -
4.4.3 Connecting PTC sensors to the
motor winding
Pt100 or Pt1000 sensors installed in the motor winding are used for thermal motor monit-
oring as part of software. View and adjust current temperature values and configure limit
temperatures with the user interface. PTC sensors installed in the hardware define the
maximum winding temperature and switch off the motor in an emergency.
CAUTION!Perform a functional check! Check the resistance prior to connecting the PTC
sensor. Use an ohmmeter to measure the temperature sensor's resistance. PTC sensors
have a cold resistance between 60 and 300ohm.
Connecting the PTC sensor to the on-site switching system:
•Operating voltage: 2.5 to 7.5VDC
•Wires: 3 and 4
•Evaluation relay for PTC sensor, e.g. for enhancing the "MCB112" Wilo-EFC PTC ther-
mistor board or "CM-MSS" relay
DANGER
Risk of explosion due to incorrect connection!
There is a risk of fatal injury within potentially explosive atmosphere if
thermal motor monitoring has been connected incorrectly! The connec-
tion must always be carried out by a qualified electrician. If used in po-
tentially explosive atmospheres:
• Connect thermal motor monitoring via an evaluation relay!
• Deactivation by the temperature limiter must be conducted with re-
activation lock! It must only be possible to restart the unit once the
unlock key has been actuated by hand!
4.4.4 Network connection Prepare the network control cable and install the enclosed RJ45 plug. Connect to a network
socket.

•Use shielded cables.
•The unit automatically configures parameters during initial commissioning. Individual di-
gital inputs are pre-assigned as part of this process. It is not possible to modify pre-as-
signments!
•Assign the corresponding function in the Digital Data Interface to guarantee correct
functionality of freely configurable inputs.

Description of preassigned input functions:
•Start
Input/output signal from primary control. NOTICE!If the input is not required, install a
converter bridge between terminals 12 and 18!
•External off
Remote deactivation using a separate switch. NOTICE!The input directly switches over
the frequency converter!
•Safe Torque Off (STO) – safe deactivation NOTICE!If the input is not required, install a
converter bridge between terminals 12 and 27!
Hardware shutdown of the pump by the frequency converter, independent of the pump
control. Automatic reactivation is not possible (reactivation lock). NOTICE!If the input
is not required, install a converter bridge between terminals 12 and 37!
It is possible to assign the following functions to available inputs at the Digital Data Inter-
face:
•High Water
Signal for overflow level.
•Dry Run
Signal for dry-running protection.
•Leakage Warn
Signal for external sealing chamber monitoring. A warning message is output in the
event of a fault.
•Leakage Alarm
Signal for external sealing chamber monitoring. The pump is shut down in the event of a
fault. Modify the alarm type in the configuration to define the downstream response.
•Reset
External signal to reset error messages.
•High Clogg Limit
Activating higher tolerance ("Power Limit - High") for clogging detection.
