Simple programming, up to 4 alarm outputs (SPDT) and optional available fully isolated free programmable analog output 0/ m; 0/ V DC offers a lot of solutions for temperature monitoring. Peak value indication for minimum and maximum measured temperature are stored in the background and can be read out from the display at any time. Short information Programming The device is programmed by frontal buttons, in connection with the LCD display. Inputs RTD (Pt100/Pt1000), 3-wire connection or thermocouple type J, K, N or S. larm outputs 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. Fault function fault in the measuring circuit could be monitored (break of wire/short-circuit). The switching function of the analog and alarm output(s) is programmable in case of an fault

4 Controls and indicators Device name Measured value Input probe larm output 1 larm output 2 larm output 3 larm output 4 Power-ON LED Parameter button Up/down buttons Description The operation of the device is implemented in 2 levels. 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 explanation page 10. Operational startup reference! The device is preset with an ex-works default setting. Therefore it must be adapted to each special application. See Page

11 Error reports Caution! Parameter locked switched on Description The parameter can not be changed, because the parameter lock for the configuration level, or work and configuration level, is switched on. Caution! Undervoltage Supply voltage to low Caution! XX Parameter error Please check t the check-up of the parameter memory, XX errors are detectet. The incorrect parameter are resetted to the factoty settings. Please check and correct parameters if necessary. Caution! XX Parameter error Calibration necessary s before, but the factory settings are incorrect. The device must be checked at works. Change of decimals? Some parameters not representable! dapt parameters automatically? Yes No Change of decimal places While changing number of decimal places, some parameters can be converted, but however, not represented! Selection "No" : Change of the decimal places is not carried out. Selection "Yes" : Decimal places are changed automatically, where the affected parameters are set to the maximum possible value. subsequent verification of the accepted parameters is absolutely necessary.
