1 Preliminary note

This document applies to the DF21xx supply modules and the DF22xx circuit
protection modules.

Read this document before use to familiarise yourself with operating conditions,
installation and operation. Keep this document during the entire duration of use of
the device.

WARNING

Adhere to the warning notes and safety instructions (→ 2 Safety instructions).

The devices are not suitable for battery-backed applications.

2 Safety instructions

• The devices are intended for use with a 24 V DC safety extra-low voltage.

• A wrong connection to voltage which is higher and/or not safely isolated may
lead to damage or conditions which are dangerous to life.

• Use the supply module only with the matching circuit protection modules.

• Observe the technical data of the circuit protection modules used.

• The devices must be installed, connected and put into operation by a qualified
electrician.

• Adhere to the national regulations regarding the installation and selection of
cables.

• Do not mount the devices and do not actuate the contact levers while live.

• Supply the devices with energy only after they have been properly installed.

• After triggering a circuit protection module and before power on again, remove

the cause of triggering (short circuit or overload).

• Check the devices for damage prior to installation. Faulty devices must not be
used.

• In case of malfunction of the unit or queries, please contact the manufacturer.
Any tampering with the device can seriously affect the safety of operators and
machinery.This is not permitted and leads to the exclusion of any liability and

warranty claims.

Green on correct operation (→ 5.1.1) yes

Orange on uncritical error (→ 5.1.3) yes

Red on critical error (→ 5.1.4) no

off missing operating voltage no

flashing independent operation(→ 5.1.2) no

flashing system start (→ 5.1.5)

5.1.1 Correct operation

No fault occurred and there is connection to the IO-Link master.

4

5.1.2 Independent operation

No connection to the IO-Link master. If there is no connection to the IO-Link
master when the operating voltage has been applied, the supply module transfers
the parameter data to the connected circuit protection modules. The behaviour
of the connected circuit protection modules is controlled via the configuration
of the supply module. Either the status of the circuit protection modules is kept

(FREEZE) or the circuit protection modules are switched off (UNFREEZE). If there

is again connection to the IO-Link master and no fault occurred, the device goes
to the "correct operation" mode.

UK

5.1.3 Uncritical error

No valid configuration data is available. The connected circuit protection modules
remain switched off. Cyclic data exchange is not possible, acyclic data exchange
is conditionally possible. After the device has received the valid configuration and
parameter data, it quits this operating mode.

5.1.4 Critical error

During initialisation an error is found or a critical error occurs. Communication with
the IO-Link master is not possible. The connected circuit protection modules are
and remain switched off.

► Reboot the device.

5.1.5 System start

The supply module is initialised when the operating voltage is applied. During this
time communication with the IO-Link master is not possible.

5.2 DF22xx circuit protection modules

The different operating states of the circuit protection modules are indicated by
LEDs.

5.3 Interrogation of module to confirm the set nominal current

Only for circuit protection modules with adjustable nominal current.

► Press the ON/OFF/reset button of the requested channel between 2 and 5

seconds.

> The status LED of the selected channel flashes red once.
> The status LED flashes orange to display the set nominal current. The LED

Flashes red once to confirm completion of the cycle. The LED flashes orange,
once or multiple times, in accordance with nominal current setting in amperes

(orange flashing once = 1 A; orange flashing twice = 2 A; etc.).

> The set nominal current is displayed five times. After 5 cycles the display

changes to the current operating status.To interrupt/stop the interrogation cycle,
and return to normal status indication mode, press the ON/OFF/reset button of
the requested channel at any time.

5.4 Setting of the nominal current

Only for circuit protection modules with adjustable nominal current.

► Set the nominal current via IO-Link using a corresponding parameter setting

software.

6.1 Temperature factor / continuous current rating

The time-current characteristic curve depends on the ambient temperature. To
determine the max. permitted load current multiply the nominal device current by
the temperature factor taking into consideration the series connection.

Ambient temperature [°C] 0 10 23 40 50 60
Temperature factor 1 1 1 0.95 0.90 0.85

With series installation the nominal device current can be max. 80% or has to be
overdimensioned accordingly. With increased temperature the load current war­ning limit "warning limit typ. 0.8 x I

" is reduced by the temperature factor.

N

6.2 Fail-safe element

The load circuits are additionally protected by the circuit protection modules that

are equipped with a fail-safe element (integrated fuse). The fail-safe element is

adapted to the nominal current I

of the respective circuit protection module and

N

the respective wire cross-sections.

7 IO-Link

The load current warning threshold can be configured via the IO-Link inter­face to provide a visual warning and a warning via IO-Link with a capacity
utilisation between 50 and 100 %.

The IO-Link devices can also be used as stand-alone devices without IO­Link master.

Extended functions of the DF2101 head module via IO-Link:

• Min. / max. value generation of the measured current and voltage values for
each channel over any period of time

• Averaging of the measured current and voltage values for each channel over
any period of time

• Permanent switching on of individual channels in order to ignore the cyclic

data exchange (e.g. to guarantee the voltage supply of important devices). The

safety function remains active.

You will find the IODDs necessary for the configuration of an IO-Link device and
