(see ?led status indicators? on page 22, line faults) output monitoring function the current output can be monitored for line breaks and maximum load. this is activate d via the configuration. in safety-related applications (s il = on), the output monitor- ing is always active. the voltag e output is not monitored. as soon as the fault has been eliminated, th e temperature transducer continues to perfor m its normal functions. (see ?led status indicators? on page 22, 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 config urations can be selected in the order key (see ?order key? on page 6). 8.13.2 service mode service mode can be selected at any time via the ifs-op-unit operator interfac e 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 temp erature 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 sign al (force). in this case, in safety-related applications the safety function of the device is deactivated and the initial va lue 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 buttons if the configuration is modified using the ifs-op-unit operator in terface and pc-based software (e.g., ifs-conf) or via dip switch, the changes made must always be checked again and released before tran sfer 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. p w r d a t e r r d o 1 4 . 2 5 . 2 2 . 2 3 . 2 4 . 3 5 . 3 2 . 3 3 . 3 m a cx mcr -e x -t- u i- up ess um form er ut d i g i ta l C out ma x. v a l ues r m a / 10 v wa r nin g do n o t s e p a r ate when ene rg ize d an d in s talle d in z o ne 2 www. phoen ix contact . com see manua l u = 253 v m u = 6,0 v d c o t C 20 ...+ 65c / C 4 ...+ 1 4 9 f amb 0,5 a (30 v a c ) / 1 a (30 v dc) i = 7, 4 m a o p = 11 m w o u = 30 v ( z one 2) m ou t in g n d 1 4 11 12 n c i o u t u o u t 1 . 1 2 . 1 5 . 1 3 . 1 4 . 1 1 . 2 2 . 2 5 . 2 3 . 2 4 . 2 1 . 3 2 . 3 5 . 3 3 . 3 4 . 3 + s - p o r t c ? s1 s2 s3

appendix - safety-related applications (sil 2) en version 04 phoenix contact a-1 appendix a1 safety-related applications (sil 2) valid hardware and firmware versions sil regulations apply to the following modules: the safety-related temperat ure transducers listed above from the macx mcr(-ex)-t-... series have been evaluated by exida certification s.a. via a full assessment in accor - dance with iec 61508 ed.1.0 to sil 2. certificate number: phoenix contact 100134c p0019 c001. a1.1 safety function and safety requirements the safety-related measuring transducers are used for the acquisition of a sensor signal (rtd, tc sensors, resistance- type sensors, mv sources), that is converted into a scaled signal and from which a standardized ?life zero? current sig - nal is generated. the entire co nversion is continuously mon - itored to a maximum transmissi on error of 5%. in the event of greater deviations, the device switches to the safe state. the safe state is an output sign al of either < 3.6 ma or > 21 ma. with the rel versions, an additional signal is generated, which is compared with up to two specified switching thresh - olds. when the first threshold is reached, the safety relay is switched on without confirmation contact and when the sec - ond threshold is reached, it is switched off. depending on the application, the safety for the switching output is imple - mented by either the series or parallel connection of relays 2 and 3, a fuse connected in series, and by monitoring the calculated switching value. in the event of deviations of more than 5%, the device swit ches to the safe state. the safe state in this case is an uncontrolled relay. the hardware is also continuous ly monitored. if an internal failure is detected, the measuring transducer also switches to the safe state (current outp ut < 3.6 ma or > 21 ma or un - controlled relay). the transition to the safe state always takes place within the internal failure detection time of 50 s. the measuring transducer is re leased (restarted) by switch - ing off the supply voltage and swit ching it back on again, by resetting the transducer via the serial interface, or by activat - ing the ?restart? option during configuration. the integrated startup tests are then performed. if the error is still present, it will be detected during these te sts. if it is still present, the measuring transducer switches back to the safe state. in addition to the safety functi ons, there are also monitoring functions for the input and the current output. evaluation failures which are detected in the measuring transducer and to which the transducer re sponds by switching to the safe state are safe failures ( s). failures where the measuring tr ansducer does not follow a change of input signal or generates an output signal that de - viates from the intended valu e by more than 5%, are eval - uated as dangerous failures ( d). both safe ( s) and dangerous ( d) failures can be detected by diagnostic measures. detected dangerous failures ( dd) are handled in the same way as safe failures. the monitoring functions refer to events whose cause is detected and reported outside of the device. note: only those devices with sil designa - tion and device firmware with revision 0.92 or higher are certified for sil 2. designation order no. standard configuration macx mcr-t-ui-up 28 11 394 macx mcr-t-ui-up-sp 28 11 860 macx mcr-t-uirel-up 28 11 378 macx mcr-t-uirel-up-sp 28 11 828 macx mcr-ex-t-ui-up 28 65 654 macx mcr-ex-t-ui-up-sp 29 24 689 macx mcr-ex-t-uirel-up 28 65 751 macx mcr-ex-t-uirel-up-sp 29 24 799 order configuration macx mcr-t-ui-up-c 28 11 873 macx mcr-t-ui-up-sp-c 28 11 970 macx mcr-t-uirel-up-c 28 11 514 macx mcr-t-uirel-up-sp-c 28 11 831 macx mcr-ex-t-ui-up-c 28 11 763 macx mcr-ex-t-ui-up-sp-c 29 24 692 macx mcr-ex-t-uirel-up-c 28 65 722 macx mcr-ex-t-uirel-up-sp-c 29 24 809 note: the evaluation unit following the measur - ing transducer (e.g., safety-related plc) must recognize these states and correspondingly con - trol the actuator as the final link in the safety chain.
