USER MANUAL 75424004 BERKER

• 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!

and GND must not be interconnected with the corres- ponding terminals of another device. Never supply sensors connected to the inputs of the analog input module (E1...E4) from the supply terminals U

and GND of a connected EIB device.Installation

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.

• 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).Power supply of connected sensors

Attention! Risk of irreparable damage to the device!

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

and GND of a connected EIB device. Power supply of connected sensors

• The connected sensors can be supplied from terminals +U

and GND (see fig. c). 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

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.Connection

• 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. GBSensors suitable for connection
