4 Configuration and programming 4 Configuration and programming 4.1 General instructions It is recommended to configure and program the device prior to installation and wiring. Configuration and programming are carried out when creating a user project in ALP. WARNUNG The device must be powered off before connecting to PC. Switch on the power supply only after the connection over USB cable is established. Proceed as follows: 1. Connect the PR100 programming connector (Fig. 6.3, Pos.
4 Configuration and programming 4.3 Analog inputs Open the node Inputs > Analog in the open window Device configuration (Fig. 4.1) and select an input for configuration. Abb. 4.1 Analog input configuration For quick access select an input in the circuit program and use Property Box (Fig. 4.2) to set the parameters. The parameter Input mode has to be set first. ACHTUNG Ensure that the input signal is connected to the correct input terminals and that the input configuration corresponds to the signal.
4 Configuration and programming With the option "4-20 mA", a 121 Ω shunt resistor is connected to each channel. – Lower measuring limit – minimum level of the input signal – Upper measuring limit – maximum level of the input signal. The lower and upper measuring limits must be set to scale the input signal. – Decimal point offset (DP) – The input value is saved as REAL32 and INT16 in the device Modbus register.
4 Configuration and programming The device can be used as master or slave. For further information about Modbus working and RS485 interface configuration see ALP HELP. 4.4.1 Master mode There can be only one master in Modbus network. The following request methods are supported: – read by time using the parameter of master Interval between requests – write by change (default) – read / write by event PR100 as a master can control up to 16 slaves. Each slave can maintain up to 256 variables.

5 Installation 5 Installation The relay is designed for DIN rail mounting. The operating conditions from the sect. 3.2 must be taken into account when choosing the installation site. For dimension drawing see Fig. A.1. Installation: 1. Place the device on a DIN rail as shown in Fig. 5.1. 2. Press the device firmly against the DIN rail in the direction of arrow 2 until the latch locks. 3. Wire the device using the supplied terminal blocks. Abb. 5.1 Removing: 1.
5 Installation WARNUNG The device must be powered off before connecting to peripheral devices or PC. Switch on the power supply only after the wiring of the device has been completed. VORSICHT The program runs after transferring it to the relay. It is recommended to transfer the program before wiring the relay. Otherwise ensure that all peripheral devices are disconnected from relay outputs before transferring the program. ACHTUNG Supply voltage may not exceed 30 V. Higher voltage can damage the device.

If it does not help, contact technical service Overheating Ensure the operation temperature according to Tab. 3.6 6.
7 Firmware update 7 Firmware update The firmware update is carried out in ALP using the menu item Device > Firmware update or during user project transfer. If the firmware update was unsuccessful (power outage, communication errors etc.), it can be forced. The forced firmware update can be made if the device is not detected in ALP, but the device connection is correctly displayed in the Windows Device Manager. To force the firmware update: 1. Connect the PR100 programming connector (Fig. 6.3, Pos.
8 Maintenance 8 Maintenance 8.1 General instructions The maintenance includes: – cleaning of the housing and terminal blocks from dust, dirt and derbis – checking the device fastening – checking the wiring (connecting leads, fastenings, mechanical damage) ACHTUNG The device should be cleaned with a damp cloth only. No abrasives or solventcontaining cleaners may be used. During maintenance, observe the safety instructions in the section "Wiring" 8.
9 Transportation and storage 9 Transportation and storage Pack the device in such a way as to protect it reliably against impact for storage and transportation. The original packaging provides optimum protection. If the device is not taken immediately after delivery into operation, it must be carefully stored at a protected location. The device should not be stored in an atmosphere with chemically active substances.

Appendix B Calibration Appendix B Calibration If the accuracy of the input or output of the module is no longer in accordance with the specification, it can be calibrated. The module must be connected to the basic device to be calibrated. The calibration is carried out the same way as with the basic device. VORSICHT Ensure reliable power supply of the basic device and modules during the calibration. If it fails, the calibration should be repeated.
Appendix B Calibration Set the three points for calibration curve and the filter time constant. The greater the filter time constant, the longer the calibration process will take, but the more accurate calculation of the coefficients will be achieved. Select the input to calibrate. If you select All, all inputs will be calibrated sequentially, therefore the appropriate reference signal has to be applied to all inputs. 7. Click Next and follow the instructions.
