Page 4: Important Notes
Important Notes Usage for the intended purpose The temperature switch TRS 5-6 serves as safety device in plants requiring official approval and is used in conjunction with resistance thermometers TRG 5-53, TRG 5-54, TRG 5-55 and TRG 5-57. Use the temperature switch only for signalling temperature limits. -
Page 5: Explanatory Notes
The failure of one channel (loss of redundancy) is signalled by the light- ing-up of one red LED. The combination of TRG 5-... and TRS 5-6 provides fail-safe protection against a first fault, i.e. the system will still continue to provide the safety function even after the occurrence of a first fault. -
