Measuring value and programmed unit are shown in the display. The integrated transmitter supply offers direct connection of loop powered sensors. Simple programming, up to 4 alarm outputs (SPDT) and optional available fully isolated free programmable analog output 0/ m; 0/ V DC meets the demand for different applications. Peak value indication for minimum and maximum measured values are stored in the background and can be read out from the display at any time. Short information Programming Inputs larm outputs Fault function The device is programmed by frontal buttons, in connection with the LCD display. Standard signal 0/ m and 0/ V DC The alarm outputs can be programmed as max. or min. function. Switch-on delay and switch-off delay time is programmable from 1 s up to 9 h. The switching status is displayed through LED s. break of wire in the measuring circuit could be monitored. The switching function of the analog and alarm output(s) is programmable in case of an fault

The required parameter is called up with the button. The selection within a parameter and the setting-adjustment of a value is implemented with the buttons and. Button combinations (press buttons simultaneously): + 1 parameter back + Parameter is set to "0" or minimum value. fter the switching on the supply voltage, the device initializes itself. In the display the message indicating device type and software version is shown. fter the initialization, the device is running in the working level. The peak value storage is called up and the setpoints of the alarm outputs can be programmed. The configuration level is called up by activation of the button for 2 seconds. In this case, all parameters which determine the properties of the device are programmed. fter the last menu item, or if no button is pressed for longer than 2 minutes, a skip-back into the working level is implemented automatically and the current measured value is indicated in the display. The configuration level can be exited at any time by holding down button for 2 seconds. Error reports In case of occurring faults, the messages are shown on the display in plain text. This simplifies location of the error. See description page 11. Operational startup reference! The device is preset with an ex-works default setting. Therefore it must be adapted to each special application. See Page
