Frequently Asked Questions - 75424004 BERKER

What is the role of the Berker 75424004 analog input module?

This module expands an EIB weather station or an EIB analog input by four additional inputs for analog transducers. It analyzes voltage (0-1 V, 0-10 V) or current (0-20 mA, 4-20 mA) signals and transmits the data to the KNX/EIB device.

How to power the module?

The module requires an external power supply of 24 V AC (e.g., ref. 7591 00 01). Maximum consumption is 170 mA. This power supply can also be used for connected sensors.

What types of sensors can be connected?

You can connect analog transducers such as brightness (WS 10H), twilight (WS 10D), temperature (WS 10T), wind (WS 10W), rain (WS 10R) or ambient humidity/temperature sensors. Other detectors can be used with manual parameter setting.

How to install the module on a DIN rail?

Mount the module on a DIN rail of 35 x 7.5 mm according to EN 50022. Connection to the EIB device is made via the supplied 6-pin system connector.

What does the status of the red LED mean?

During commissioning: on = self-test OK; fast flashing = initializing; slow flashing = module not configured; off = initialized. In normal operation: on = fault; off = normal operation.

Can I hot-swap the module?

Yes, you can replace a defective module with an identical model during normal operation after disconnecting the module's power. The KNX/EIB device resets to initial state after 25 seconds.

What is the power supply capacity for external sensors?

The +U_s and GND terminals provide a voltage of 24 V DC with a maximum current of 100 mA. In case of overcurrent or short-circuit, the voltage is cut off and automatically restored after fault elimination.

What safety precautions should be observed?

Installation must be carried out by a qualified electrician. Do not connect the U_s and GND terminals to other devices. Do not power sensors via the Us and GND terminals of an EIB device. Observe fire prevention regulations.

How to clean the module?

Clean the module with a dry cloth. Do not use abrasive products or solvents. Disconnect the power before cleaning.

What to do in case of module defect?

Send the defective device postage paid to Berker after-sales service with a description of the defect. Replacement with an identical module can be carried out during normal operation after disconnecting the module's power.

USER MANUAL 75424004 BERKER

Operating Instructions

• Electrical equipment must be installed and fitted by qualified electricians only and in strict observance of the relevant accident prevention regulations.
• Failure to observe any of the installation instructions may result in fire and other hazards.
• Risk of irreparable damage to the device!

U_s and GND must not be interconnected with the corresponding terminals of another device.

Never supply sensors connected to the inputs of the analog input module (E1...E4) from the supply terminals U_s and GND of a connected EIB device.

GB

Function

• This analog input module extends an EIB weather station 'Komfort' order no. 7541 40 03 or an EIB analog input, order no. 7541 40 04 by four additional sensor inputs for analog transducers.
• Measuring data evaluation and limit processing take place in the KNX/EIB device.
• The analog input module accepts both voltage and current signals: Voltage signals: 0 ... 1 V DC 0 ... 10 V DC Current signals: 0 ... 20 mA DC 4 ... 20 mA DC
• The current inputs 4 ... 20 mA can be monitored for wire breakage (parameter setting).

Installation

GB

The device is snap-fastened on a 35 x 7.5 mm rail as per EN 50022.

An analog input module must be connected to the EIB device by means of the 6-pole system connector only (supplied with the analog input module).

For operation, the analog input module needs an external 24 V power supply unit, e.g. order no. 7591 00 01.

In addition, the unit can supply power to connected sensors as e.g. WS 10W, WS 10R, their heating circuits or to the connected KNX/EIB device.

GB

Power supply of connected sensors

• The connected sensors can be supplied from terminals +U_s and GND (see fig. ①). These terminals are provided in duplicate and internally interconnected.
• The total current consumption of all sensors supplied this way must not exceed 100 mA.
• In the event of overload or short-circuit between +U_s and GND, the power will be switched off. After removal of the fault, the power is switched on again automatically.
• Sensors connected can also be supplied externally (e.g. if their current consumption exceeds 100 mA). In such case, they must be connected between terminals E1...E4 and GND.

Attention!

Risk of irreparable damage to the device!

U_s and GND must not be interconnected with the corresponding terminals of another device.

Never supply sensors connected to the inputs of the analog input module (E1...E4) from the supply terminals U_s and GND of a connected EIB device.

Please observe the following basic rules when installing an analog input module:

• Replacement of a module (e.g. in case of defect) by one of the same type can be effected during operation of the system (for this purpose, disconnect the module from the power supply). After replacement, the KNX/EIB device will reset after abt. 25 s. All inputs and outputs of the KNX/EIB device and the modules connected are then re-initialized and reset to their original state.
• Removing or adding modules without adapting their project configuration and subsequent downloading into the KNX/EIB device is not allowed as this will result in system failure.

Status LED

During commissioning of the module:

On : Module ready for operation (self-test OK).

Quickly blinking : Module initialization in progress

Slowly blinking : Module not configured (in EIB device)

Off : Module initialized and in operation

Precondition: LED must have been on beforehand!

Normal operation:

On : Module not ready for operation (fault condition)

Off : Modul initialized and in operation.

Precondition: LED must have been on beforehand!

Slowly blinking = 1/s; quickly blinking = 2/s
