Input monitoring function The input monitoring function for line break and short circuit refers to the sensor connected to the input. When an error is detected, the output signal is set to the configured error value. In the case of RTD sensors and resistance-type sen- sors, short-circuit failures are detected resistance values <1 Ω. Short circuits of thermocouples and mV sources cannot be detected, since 0 V can be a valid signal. On RTD sensors, resistance-type sensors and potentiome- ters, a line break is detected when the current flow through the sensor is faulty. As soon as the fault has been eliminated, the temperature transducer continues to perform its normal functions. (see “LED status indicators” on page 23, Line faults) Output monitoring function The current output can be monitored for line breaks and maximum load. This is activated via the configuration. In safety-related applications (SIL = ON), the output monitor- ing is always active. The voltage output is not monitored. As soon as the fault has been eliminated, the temperature transducer continues to perform its normal functions. (see “LED status indicators” on page 23, Line faults) 8.13 Operating modes 8.13.1 SIL ON/SIL OFF The temperature transducer can either be operated in SIL ON or SIL OFF. The standard configuration is SIL ON with DIP switch S1 set to the OFF position. With the order config- uration, customer-specific configurations can be selected in the order key (see “Order key” on page 7). 8.13.2 Service mode Service mode can be selected at any time via the IFS-OP-UNIT operator interface and the configuration soft- ware, e.g., IFS-CONF or via DIP switch S1. If settings are changed during service mode and service mode is then exited, the temperature transducer performs a warm start in order to apply the newly set values. If no changes are made, the transducer starts up in normal mea- suring mode without a warm start. The switching output switches according to its configuration. In service mode, it is also possible to simulate the output sig- nal independently of the input signal (force). In this case, in safety-related applications the safety function of the device is deactivated and the initial value for the analog output sig- nal is 2 mA, which allows subsequent devices to detect the deviation from normal operation as a result of the measured value being underrange. During service mode, the switching output is deactivated and remains in its idle position. 9Configuration Figure 7 Position of the DIP switch and button If the configuration is modified using the IFS-OP-UNIT operator interface and PC-based software (e.g., IFS-CONF) or via DIP switch, the changes made must always be checked again and released before transfer to the temperature transducer. After the transfer, the new data in the temperature transducer is applied by means of activation and a warm start. WARNING: Explosion hazard When configuring in zone 2, the PC used must be approved for use in zone 2. When a DIP switch from S1-2 ... S1-8 (ON) is switched on, the device is switched to service mode. The red ERR LED flashes (1.2 Hz) and a diagnostic I/O fault is displayed in the start screen.
