Product Description:

In case of a detected open-circuit the numerical value of 32767 is set. If the sensor is short-circuited, the numerical value of -32767 is set.If the open-circuit or short-circuit monitoring is configured, the detected error is displayed by the red LED Ovl as long as it is present. In the PLC system an error message is
stored (FK4, error number 9). In order to avoid error messages with unused analog inputs, it is useful, not to configure this channels for Pt100.In the operating mode "Pt100 in 3-wire configuration"two adjacent analog inputs belong together (e.g. EW 6,00 and EW 6,01). For configuration, both inputs must be configured to the desired operating mode, see configuration table Fig. 4-18.The constant current of the one channel flows through the Pt100 resistance sensor, the constant current of the other channel through one of the wires. The basic unit 07 KT 94 calculates the measuring valuefrom the two voltage drops and stores it under the odd
address (e.g. EW 6,01).

Product's Character:

When resistance thermometers are used, a constant current must flow through the measuring resistor in order to create the necessary voltage drop for the evaluation. For this purpose, the basic unit 07 KT 94 provides a constant current sink, which is multiplexed to the 8 analog channels. The following figure shows the connection of Pt100 resistance thermometers in 2-wire configuration. it has to be measured bipolar in order to compensate measuring errors. Additionally, in case of singlepole configuration, AGND1 would be connected directly to the remote earth potential. This would cause inadmissable (and possibly dangerous) earthing loops. In all configurations using differential inputs two adjacent analog inputs belong together (e.g. EW 6,00 and EW 6,01).
