Bosch Rexorth Electronic contact thermometer ABZMT-1X/0300MS/E3-T2-K24 R901247787 Rexroth

Electronic contact thermometers are used for the temperature control of hydraulic systems.
The contact thermometers have two or four programmable temperature switching outputs, or alternatively one programmable switching output and one analog output 4 … 20 mA, with display and control unit.
The temperature display can be selected in °C or °F.
Display and control unit function
The micro-processor controlled display and control unit processes the analog input signals for the analysis of the temperature control. The temperature can be set at the control unit in an easy menu navigation by means of pushbuttons and the settings can be read off at the LED display.
The display and control unit has a four-digit, red seven-segment LED display and 3 pushbuttons for the operation as well as up to 4 LEDs integrated in the front plate for the display of alarm conditions.
The device moreover has two (t2) and/or four (T4) freely adjustable PNP switching outputs plus the adjustable switch-back points. One PNP output can be programmed as frequency output. Alternatively one freely programmable PNP switching output and one 4 … 20 mA output for the continuous temperature measurement. The switching conditions are shown in the display which can be rotated by 270° (version D0).
The output 4 … 20 mA can optionally be set to 0 … 10 V, 2 … 10 V or 0 … 5V.
Depending on the setting for the measured temperature, the desired unit (°C, °F) will be displayed. By default, the temperature display is set to °C.
During the setting and/or programming of the corresponding process parameters, the parameter values and/or the related menu items are shown in the display. In case of energy supply failure, all input values will be stored, the max/min values can be called from a permanent memory, if necessary.
Parameterization
The menu navigation is based on the VDMA standard sheet for fluid sensors 24574-1.
The operating menu is designed hierarchically as tree structure.
That means that frequently used functions and adjustment points are quickly accessible and rarely used menu items can be found in a submenu.
Using the ▲ and ▼ keys, the corresponding parameters are set and/or the next menu item is displayed.
Using the ► key, the selected menu item is selected and/or the set parameter is accepted and stored.
The parameter may be a numerical value and a selection of functions (e.g. NO [output as normally open contact], NC [output as normally closed contact] or i1 [analog output 4 … 20 mA]).
After confirmation of a parameter or function selection by means of the ► key, the display will switch back to the current menu item. Then, you can use ▲ and ▼ to display the next menu item and the ► key to select it.
